Methods and systems for generating and reading 2d barcodes

FIELD OF THE TECHNOLOGY

0001The present disclosure relates to the field of information processing technologies, and in particular, to methods and systems for generating and reading 2D barcodes.

BACKGROUND OF THE DISCLOSURE

0002With the ongoing development of information processing technologies, a 2D barcode has found wide application for its characteristics such as wide encoding range and high fault tolerance. A Quick Response (QR) 2D barcode is one type of 2D barcode, and each QR2D barcode is represented in the form of an image, where the image is a square array. The generation of a 2D barcode refers to conversion of information into an image, and reading of a 2D barcode refers to conversion of an image into information. As the application scope of a 2D barcode is broadened, the types and quantity of information recorded in a 2D barcode keep growing, especially, information involving privacy of a user. Further, after 2D barcode software installed on a terminal scans the 2D barcode, information recorded in the 2D barcode may be directly obtained. When information recorded in a 2D barcode is private information, security of the private information cannot be protected. Therefore, how to generate and read a 2D barcode for private information becomes an issue that draws people's attention.

0003Currently there are two manners of generating and reading a 2D barcode. A first manner of generating a 2D barcode is: acquiring private information, and enciphering the private information; and generating a 2D barcode according to the enciphered private information. A first manner of reading a 2D barcode is: acquiring a 2D barcode, and scanning the 2D barcode, to obtain enciphered private information; and deciphering the enciphered private information by using a deciphering manner corresponding to an enciphering manner, to obtain the private information, and using the private information as a reading result of the 2D barcode.

0004A second manner of generating a 2D barcode is: acquiring private information and a private information indicator, the private information indicator being for distinguishing private information from nonprivate information and indicating whether to present the private information; and generating a 2D barcode according to the private information and the private information indicator. A second manner of reading a 2D barcode is: scanning a 2D barcode, to obtain private information and a private information indicator, so that if the private information indicator indicates to present the private information, the private information is used as a reading result of the 2D barcode, and if the private information indicator indicates not to present the private information, the reading result of the 2D barcode is empty, that is, the private information cannot be read.

0005In a process of implementing the present disclosure, the inventor finds that the existing technology at least has the following problems:

0006In the first manner of generating a 2D barcode, private information is enciphered, so that information recorded in a generated 2D barcode includes the enciphered private information; however, the enciphered private information is at a risk of being cracked, resulting in that security of private information cannot be ensured, and a cost of generating a 2D barcode is increased for enciphering of private information. In the first manner of reading a 2D barcode, a deciphering manner corresponding to an enciphering manner needs to be used, so that a cost of reading a 2D barcode is increased, and application of a 2D barcode is adversely affected. In the second manner of generating a 2D barcode, a generated 2D barcode includes private information, and security of private information cannot be ensured either. In the second manner of reading a 2D barcode, although presentation of private information may be indicated by using a private information indicator, security of private information still cannot be ensured.

0007It is noted that <patcit id="pcit0001" dnum="US8356033B2"><text>patent publication US 8,356,033B2</text></patcit> discloses a photographing device which is capable of easily uploading a photographic image to an online album server in an album system by using a wireless communication function and is capable of easily setting up management information of the photographic image.

0008It is further noted that <patcit id="pcit0002" dnum="WO2014044183A1"><text>patent publication WO 2014/044183 A1</text></patcit> discloses methods and devices for resource sharing. Address information of a resource to be shared can be acquired by a user device in response to a sharing request. A two-dimensional barcode corresponding to the address information of the resource can be generated by the user device. The generated two-dimensional barcode can be published by the user device to one or more of an Internet platform and a specified Internet communication application client via a network.

Embodiment 3

0038An embodiment of the present invention provides a method for generating a 2D barcode. The method provided in the embodiment of the present invention is described in detail with reference to the above content in Embodiment 1. Referring to <figref idref="f0003">FIG. 5</figref>, a procedure of the method includes: 501: A terminal acquires private information input by a user, and sends the acquired private information to a server through a network.

0039A manner of acquiring private information input by a user is not specifically limited in this embodiment. Specific implementation includes, but is not limited to: providing an information input interface, the input interface being further provided with a submit button; and acquiring information input, through the information input interface, by a user, and using, when it is detected that the user clicks the submit button, the information input, through the information input interface, by the user as the acquired private information input by the user.

0040To ensure security of the private information, the method provided in this embodiment includes, but is not limited to, sending the acquired private information to the server through the network.

0041In addition, referring to an architecture diagram of a secure 2D barcode service system shown in <figref idref="f0004">FIG. 6</figref>, the secure 2D barcode service system includes a client program and an information storage subsystem. The client program includes an information processing module and a 2D barcode module. The information processing module is connected to a user input, and the 2D barcode module is connected to scanning of a 2D barcode by a user. The information storage subsystem includes a data processing module, a network service module, and a 2D barcode information database. The network service module is connected to the scanning of the 2D barcode by the user. The user input correspondingly acquires private information input by the user, and the information processing module is configured to send the private information to a server through a network.

0042502: The server receives the private information sent, through the network, by the terminal, and stores the private information.

0043Referring to the architecture diagram of the secure 2D barcode service system shown in <figref idref="f0004">FIG. 6</figref>, the network service module is configured to receive the private information sent, through the network, by the terminal, and transfer the private information to the data processing module, so that the data processing module saves the private information in the 2D barcode information database.

0044It should be noted that in the method provided in the embodiment of the present invention, private information is stored on a server, so that a generated 2D barcode does not include private information, so that security of private information is ensured. A manner in which the server stores the private information is not specifically limited in this embodiment, and includes, but is not limited to, storing each piece of private information according to an information identifier of the private information.

0045503: The server generates an information access address corresponding to the private information.

0046Because private information is stored on a server side, to access private information, in the method provided in this embodiment, the server generates the information access address corresponding to the private information, the information access address being for accessing the private information. During specific implementation, the generated information access address may be one Uniform Resource Locator (URL).

0047As an embodiment, the generating an information access address corresponding to the private information includes, but is not limited to: <ul id="ul0017" list-style="none"><li>acquiring an information identifier of the private information, and storing the information identifier, one information identifier corresponding to one piece of private information; and</li><li>generating the information access address including the information identifier of the private information.</li></ul>

0048A manner of acquiring the information identifier of the private information is not specifically limited in this embodiment. Specific implementation includes, but is not limited to, calculating a Message Digest Algorithm 5 (MDS) value according to the entire private information, and the MDS value is a 64-bit 8-byte integral type. The MDSvalue is used as the acquired information identifier of the private information. Because one information identifier corresponds to one piece of private information, an information identifier is used as an information access address, so that private information may be accessed by using an information identifier.

0068Neither of manners of acquiring a 2D barcode including an information access address and scanning the 2D barcode is specifically limited in this embodiment. During specific implementation, a 2D barcode may be generated by using the method provided in Embodiment 3 above, and the 2D barcode is used as the acquired 2D barcode including the information access address. After the 2D barcode is acquired, the 2D barcode may be scanned by using a 2D barcode scanning device. The 2D barcode scanning device may be a mobile phone, a tablet computer, and the like. Because the acquired 2D barcode includes the information access address, after the 2D barcode is scanned, the information access address included in the 2D barcode may be obtained, the information access address being for accessing private information.

0069In addition, referring to an architecture diagram of the secure 2D barcode service system shown in <figref idref="f0004">FIG. 6</figref>, a user scans a 2D barcode to correspondingly acquire a 2D barcode including an information access address, and a 2D barcode module is configured to scan the 2D barcode, to obtain the information access address included in the 2D barcode.

0070802: The terminal sends the information access address to a server through a network.

0071To enable acquisition of private information according to an information access address, in the method provided in this embodiment, the information access address is sent to the server through the network.

0074804: The server searches prestored private information for private information corresponding to the information access address.

0075In this embodiment, a manner of searching for the private information corresponding to the information access address is not limited. During specific implementation, because the information access address is for accessing private information, the prestored private information may be directly searched for the private information corresponding to the information access address.

0076As an embodiment, the information access address includes an information identifier of the private information; and <ul id="ul0019" list-style="none"><li>the searching prestored private information for private information corresponding to the information access address includes:</li><li>searching the prestored private information for the private information corresponding to the information identifier included in the information access address.</li></ul>

0077By using the information identifier, the prestored private information may be rapidly searched for the private information corresponding to the information identifier included in the information access address.

0078As an embodiment, the information access address further includes a check identifier and/or a time identifier; the searching the prestored private information for the private information corresponding to the information identifier included in the information access address includes: <ul id="ul0020" list-style="none"><li>determining whether the check identifier included in the information access address is consistent with a prestored check identifier, and/or determining whether the time identifier included in the information access address is ineffective; and</li><li>executing, if the check identifier included in the information access address is consistent with the prestored check identifier, and/or the time identifier included in the information access address is not ineffective, the step of searching the prestored private information for the private information corresponding to the information identifier included in the information access address.</li></ul>

0079The information access address provided in this embodiment may include the information identifier of the private information, or may further include the information identifier of the private information and the check identifier corresponding to the private information, or may further include the information identifier of the private information and the time identifier corresponding to the private information, or may further include the information identifier of the private information, the check identifier corresponding to the private information, and the time identifier corresponding to the private information. For the four types of information access addresses, during the search for the private information, four cases are included: <ol id="ol0001"><li>(1) When the information access address includes the information identifier of the private information, the prestored private information is directly searched for the private information corresponding to the information identifier included in the information access address.</li><li>(2) When the information access address includes the information identifier of the private information and the check identifier corresponding to the private information, it is determined whether the check identifier included in the information access address is consistent with the prestored check identifier; and when the check identifier included in the information access address is consistent with the prestored check identifier, the step of searching the prestored private information for the private information corresponding to the information identifier included in the information access address is executed.</li><li>(3) When the information access address includes the information identifier of the private information and the time identifier corresponding to the private information, it is determined whether the time identifier included in the information access address is ineffective; and when the time identifier included in the information access address is not ineffective, the step of searching the prestored private information for the private information corresponding to the information identifier included in the information access address is executed.</li><li>(4) When the information access address includes the information identifier of the private information, the check identifier corresponding to the private information, and the time identifier corresponding to the private information, it is determined whether the check identifier included in the information access address is consistent with the prestored check identifier; when the check identifier included in the information access address is consistent with the prestored check identifier, it is determined whether the time identifier included in the information access address is ineffective; and when the time identifier included in the information access address is not ineffective, the step of searching the prestored private information for the private information corresponding to the information identifier included in the information access address is executed.</li></ol>

0080For ease of understanding, an example in which the information identifier corresponds to a user information ID, the check identifier corresponds to a check KEY value, and the time identifier corresponds to a timestamp is used for description. When it is determined that the check KEY value included in the information access address is consistent with the prestored check KEY value, it is determined that the information access address is effective; and when it is determined that the check KEY value included in the information access address is inconsistent with the prestored check KEY value, it is determined that the information access address is ineffective, and it is returned that acquisition of private information fails.

0081The determination of whether the time identifier included in the information access address is ineffective includes, but is not limited to, comparing time recorded in the timestamp with time of a current server; if a difference value between the time recorded in the timestamp and the time of the current server is greater than a preset time threshold, it is determined that the time identifier included in the information access address is ineffective, and it is returned that acquisition of private information fails; and if the difference value between the time recorded in the timestamp and the time of the current server is not greater than the preset time threshold, it is determined that the time identifier included in the information access address is effective. The preset time threshold may be 5 minutes. Certainly, in addition to the above preset time threshold, other preset time thresholds such as 4 minutes and 6 minutes may be further used, and are specifically limited in this embodiment.

0106An embodiment of the present invention provides a terminal. Please refer to <figref idref="f0010">FIG. 16</figref>, which is a schematic structural diagram of a terminal involved in the embodiment of the present invention, and the terminal may be configured to implement the method for generating a 2D barcode provided in the above embodiment. Specifically: The terminal 1600 may include components such as a Radio Frequency (RF) circuit 110, a memory 120 including one or more computer readable storage media, an input unit 130, a display unit 140, a sensor 150, an audio circuit 160, a Wireless Fidelity (WiFi) module 170, a processor 180 including one or more processing cores, and a power supply 190. A person skilled in the art may understand that the structure of the terminal shown in <figref idref="f0010">FIG. 16</figref> does not constitute a limitation to the terminal, and the terminal may include more components or fewer components than those shown in the figure, or some components may be combined, or a different component deployment may be used.

0107The RF circuit 110 may be configured to receive and send signals during an information receiving and sending process or a call process. Particularly, downlink information from a base station is received and then delivered to one or more processors 180 for processing. In addition, related uplink data is sent to the base station. Generally, the RF circuit 110 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), and a duplexer. In addition, the RF circuit 110 may also communicate with a network and another device by wireless communication. The wireless communication may use any communications standard or protocol, which includes, but is not limited to, Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), e-mail, Short Messaging Service (SMS), and the like.

0108The memory 120 may be configured to store a software program and module. The processor 180 runs the software program and module stored in the memory 120, to implement various functional applications and data processing. The memory 120 may mainly include a program storage area and a data storage area. The program storage area may store an operating system, an application program required by at least one function (such as a sound playback function and an image display function), and the like. The data storage area may store data (such as audio data and an address book) created according to use of the terminal 1600, and the like. In addition, the memory 120 may include a high speed random access memory, and may also include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory, or another volatile solid-state storage device. Accordingly, the memory 120 may further include a memory controller, so that the processor 180 and the input unit 130 access the memory 120.

0109The input unit 130 may be configured to receive input digit or character information, and generate a keyboard, mouse, joystick, optical, or track ball signal input related to the user setting and function control. Specifically, the input unit 130 may include a touch-sensitive surface 131 and another input device 132. The touch-sensitive surface 131, which may also be referred to as a touch screen or a touch panel, may collect a touch operation of a user on or near the touch-sensitive surface (such as an operation of a user on or near the touch-sensitive surface 131 by using any suitable object or accessory, such as a finger or a stylus), and drive a corresponding connection apparatus according to a preset program. Optionally, the touch-sensitive surface 131 may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch position of the user, detects a signal generated by the touch operation, and transfers the signal to the touch controller. The touch controller receives the touch signal from the touch detection apparatus, converts the touch signal into touch point coordinates, and sends the touch point coordinates to the processor 180. Moreover, the touch controller can receive and execute a command sent from the processor 180. In addition, the touch-sensitive surface 131 may be may be a resistive, capacitive, infrared, or surface sound wave type touch-sensitive surface. In addition to the touch-sensitive surface 131, the input unit 130 may further include the another input device 132. Specifically, the another input device 132 may include, but is not limited to, one or more of a physical keyboard, a functional key (such as a volume control key or a switch key), a track ball, a mouse, and a joystick.

0110The display unit 140 may be configured to display information input by the user or information provided for the user, and various graphical user interfaces of the terminal 1600. The graphical user interfaces may be formed by a graph, a text, an icon, a video, and any combination thereof. The display unit 140 may include a display panel 141. Optionally, the display panel 141 may be configured by using a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch-sensitive surface 131 may cover the display panel 141. After detecting a touch operation on or near the touch-sensitive surface 131, the touch-sensitive surface 131 transfers the touch operation to the processor 180, so as to determine the type of the touch event. Then, the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although, in <figref idref="f0010">FIG. 16</figref>, the touch-sensitive surface 131 and the display panel 141 are used as two separate parts to implement input and output functions, in some embodiments, the touch-sensitive surface 131 and the display panel 141 may be integrated to implement the input and output functions.

0111The terminal 1600 may further include at least one sensor 150, such as an optical sensor, a motion sensor, and other sensors. Specifically, the optical sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor may adjust luminance of the display panel 141 according to brightness of the ambient light. The proximity sensor may switch off the display panel 141 and/or backlight when the terminal 1600 is moved to the ear.

0141An embodiment of the present invention provides a terminal. Please refer to <figref idref="f0012">FIG. 19</figref>, which is a schematic structural diagram of a terminal involved in the embodiment of the present invention. The terminal may be configured to implement the method for reading a 2D barcode provided in the foregoing embodiment. Specifically:

0142The terminal 1900 may include components such as a Radio Frequency (RF) circuit 210, a memory 220 including one or more computer readable storage media, an input unit 230, a display unit 240, a sensor 250, an audio circuit 260, a Wireless Fidelity (WiFi) module 270, a processor 280 including one or more processing cores, and a power supply 290. A person skilled in the art may understand that the structure of the terminal shown in <figref idref="f0012">FIG. 19</figref> does not constitute a limitation to the terminal, and the terminal may include more components or fewer components than those shown in the figure, or some components may be combined, or a different component deployment may be used.

0143The RF circuit 210 may be configured to receive and send signals during an information receiving and sending process or a call process. Particularly, downlink information from a base station is received and then delivered to one or more processors 280 for processing. In addition, related uplink data is sent to the base station. Generally, the RF circuit 210 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), and a duplexer. In addition, the RF circuit 210 may also communicate with a network and another device by wireless communication. The wireless communication may use any communications standard or protocol, which includes, but is not limited to, Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), e-mail, Short Messaging Service (SMS), and the like.

0144The memory 220 may be configured to store a software program and module. The processor 280 runs the software program and module stored in the memory 220, to implement various functional applications and data processing. The memory 220 may mainly include a program storage area and a data storage area. The program storage area may store an operating system, an application program required by at least one function (such as a sound playback function and an image display function), and the like. The data storage area may store data (such as audio data and an address book) created according to use of the terminal 1900, and the like. In addition, the memory 220 may include a high speed random access memory, and may also include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory, or another volatile solid-state storage device. Accordingly, the memory 220 may further include a memory controller, so that the processor 280 and the input unit 230 access the memory 220.

0145The input unit 230 may be configured to receive input digit or character information, and generate a keyboard, mouse, joystick, optical, or track ball signal input related to the user setting and function control. Specifically, the input unit 230 may include a touch-sensitive surface 231 and another input device 232. The touch-sensitive surface 231, which may also be referred to as a touch screen or a touch panel, may collect a touch operation of a user on or near the touch-sensitive surface (such as an operation of a user on or near the touch-sensitive surface 231 by using any suitable object or accessory, such as a finger or a stylus), and drive a corresponding connection apparatus according to a preset program. Optionally, the touch-sensitive surface 231 may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch position of the user, detects a signal generated by the touch operation, and transfers the signal to the touch controller. The touch controller receives the touch signal from the touch detection apparatus, converts the touch signal into touch point coordinates, and sends the touch point coordinates to the processor 280. Moreover, the touch controller can receive and execute a command sent from the processor 280. In addition, the touch-sensitive surface 231 may be may be a resistive, capacitive, infrared, or surface sound wave type touch-sensitive surface. In addition to the touch-sensitive surface 231, the input unit 230 may further include the another input device 232. Specifically, the another input device 232 may include, but is not limited to, one or more of a physical keyboard, a functional key (such as a volume control key or a switch key), a track ball, a mouse, and a joystick.

0146The display unit 240 may be configured to display information input by the user or information provided for the user, and various graphical user interfaces of the terminal 1900. The graphical user interfaces may be formed by a graph, a text, an icon, a video, and any combination thereof. The display unit 240 may include a display panel 241. Optionally, the display panel 241 may be configured by using a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch-sensitive surface 231 may cover the display panel 241. After detecting a touch operation on or near the touch-sensitive surface 231, the touch-sensitive surface 231 transfers the touch operation to the processor 280, so as to determine the type of the touch event. Then, the processor 280 provides a corresponding visual output on the display panel 241 according to the type of the touch event. Although, in <figref idref="f0012">FIG. 19</figref>, the touch-sensitive surface 231 and the display panel 241 are used as two separate parts to implement input and output functions, in some embodiments, the touch-sensitive surface 231 and the display panel 241 may be integrated to implement the input and output functions.

0147The terminal 1900 may further include at least one sensor 250, such as an optical sensor, a motion sensor, and other sensors. Specifically, the optical sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor may adjust luminance of the display panel 241 according to brightness of the ambient light. The proximity sensor may switch off the display panel 241 and/or backlight when the terminal 1900 is moved to the ear. As one type of motion sensor, a gravity acceleration sensor may detect magnitude of accelerations in various directions (generally on three axes), may detect magnitude and a direction of the gravity when static, and may be applied to an application that recognizes the attitude of the mobile phone (for example, switching between landscape orientation and portrait orientation, a related game, and magnetometer attitude calibration), a function related to vibration recognition (such as a pedometer and a knock), and the like. Other sensors, such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be configured in the terminal 1900, are not further described herein.

0148The audio circuit 260, a loudspeaker 261, and a microphone 262 may provide audio interfaces between the user and the terminal 1900. The audio circuit 260 may convert received audio data into an electric signal and transmit the electric signal to the loudspeaker 261. The loudspeaker 261 converts the electric signal into a sound signal for output. On the other hand, the microphone 262 converts a collected sound signal into an electric signal. The audio circuit 260 receives the electric signal and converts the electric signal into audio data, and outputs the audio data to the processor 280 for processing. Then, the processor 280 sends the audio data to, for example, another terminal by using the RF circuit 210, or outputs the audio data to the memory 220 for further processing. The audio circuit 260 may further include an earplug jack, so as to provide communication between a peripheral earphone and the terminal 1900.

The program stored in the storage medium 2030 may include one or more modules (not shown), and each module may include operations on a series of instructions in the server 2000: <ul id="ul0041" list-style="none"><li>receiving an information access address sent, through a network, by a terminal and for accessing private information;</li><li>searching prestored private information for private information corresponding to the information access address; and</li><li>returning the found private information to the terminal through the network, so that the terminal uses the private information as a reading result of a 2D barcode.</li></ul>

0163In another embodiment, the following instructions may be further included:

0164The information access address includes an information identifier of the private information; and the searching prestored private information for private information corresponding to the information access address includes: searching the prestored private information for the private information corresponding to the information identifier included in the information access address.

0165In another embodiment, the following instructions may be further included: <ul id="ul0042" list-style="none"><li>the information access address further includes a check identifier and/or a time identifier; and</li><li>the searching the prestored private information for the private information corresponding to the information identifier included in the information access address includes: <ul id="ul0043" list-style="none"><li>determining whether the check identifier included in the information access address is consistent with a prestored check identifier, and/or determining whether the time identifier included in the information access address is ineffective; and</li><li>executing, if the check identifier included in the information access address is consistent with the prestored check identifier, and/or the time identifier included in the information access address is not ineffective, the step of searching the prestored private information for the private information corresponding to the information identifier included in the information access address.</li></ul></li></ul>

0166Furthermore, the central processing unit 2022 may be set to communicate with the storage medium 2030, and operations of a series of instructions in the storage medium 2030 are executed on the server 2000.

0167The server 2000 may further include one or more power supplies 2026, one or more wired or wireless network interfaces, 2050, one or more input/output interfaces 2058, and/or, one or more operating systems 2041, for example, Windows Server^™, Mac OS X^™, Unix^™, Linux^™, and FreeBSD^™.

0168In the server provided in the embodiment of the present invention, an information access address sent by a terminal through a network is received, and private information corresponding to the information access address found from prestored private information is returned to the terminal through the network, so that the terminal uses the private information as a reading result of a 2D barcode; therefore, reading of a 2D barcode is implemented without deciphering, a cost of reading a 2D barcode is reduced, an application scope of a 2D barcode is broadened, and a read 2D barcode includes an information access address, so that security of private information is ensured.

0169It should be noted that when the terminal for reading a 2D barcode and the server provided in the foregoing embodiments read a 2D barcode, the foregoing division of functional modules is only used as an example for description. In practical applications, the foregoing functions may be allocated to be accomplished by different functional modules according to needs, that is, the internal structures of the terminal and the server are divided into different functional modules to accomplish all or some of the functions described above. In addition, the terminal for generating a 2D barcode and the server provided in the foregoing embodiments share the same concept with the embodiments of the method for reading a 2D barcode, and reference may be made to the method embodiments for the specific implementation processes of the terminal and the server, which are no longer elaborated herein.
