Keyless lock system

The present invention relates to a keyless lock system that can be locked and unlocked without using a key.

In the conventional key lock system, if the door is locked with the key attached in a car, or if the key is lost or stolen, the key lock cannot be released and the key lock is released. I had no choice but to ask a professional contractor to unlock the key. Further, in such a conventional locking system using a key, there is a risk that the lock may be unlocked by an unrelated third party when the key is lost or stolen.

As a lock system that solves these problems and improves convenience and security, biometric information of users with legitimate authority is registered in advance, and the biometric information is used to authenticate the user. A keyless lock system that unlocks and locks the lock has been proposed (see, for example, Patent Document 1).

However, simply by authenticating the user using biometric information, if the specified phrase or voiceprint data is recorded by a malicious third party, unauthorized unlocking by the third party will occur. It cannot be prevented. In particular, since voice and the like can be stolen relatively easily by recording, it is not possible to completely prevent spoofing by another person when only biometric information is used.

Further, in the conventional key lock system, there are various inconveniences because the person who unlocks the key must be in the locked place. For example, a child may return home while a parent is out. If the child does not have a mobile phone at that time, or if the child's authentication data is not registered in the keyless lock system, the child cannot normally enter the house. Also, even if you realize that you have forgotten to lock the front door of your home while you are out, you cannot lock it unless you return to your home from wherever you are.

In order to eliminate such inconvenience, a keyless lock system that enables locking and unlocking from a remote location using a mobile phone has been proposed (see, for example, Patent Documents 2 and 3).

However, in the system described in Patent Document 2 above, it is necessary to obtain certification at the driver identification center, and in the system described in Patent Document 3 above, locking / unlocking cannot be performed without going through a management server on the Internet. .. Therefore, it cannot be used when the object to be locked is in an area where the radio wave from the base station of the mobile phone system does not reach. For example, if you park your car in a parking lot in the mountains far from the city, you cannot unlock it even if you have a car in front of you.<patcit num="1"><text>Japanese Unexamined Patent Publication No. 2003-27788</text></patcit><patcit num="2"><text>Japanese Unexamined Patent Publication No. 2001-241229</text></patcit><patcit num="3"><text>JP-A-2002-288750</text></patcit>

<p> The conventional keyless lock system described above has the following problems. (1) A system that authenticates using biometric information cannot prevent spoofing by another person if the biometric information itself is stolen. (2) A system that uses a mobile phone to access a server or the like for authentication cannot be used in a place where radio waves from the base station of the mobile phone system do not reach.</p><p> An object of the present invention is that even if biometric information is stolen, it is possible to prevent spoofing of another person, and it can be used even in a place where radio waves from a base station of a mobile phone system do not reach. It is to provide a keyless lock system that achieves both improvements.</p>

<p> In order to achieve the above object, the keyless lock system of the present invention is a keyless lock system capable of locking and unlocking without using a key, and includes a biometric data input device for inputting biometric data and the above. A recognition processing unit that recognizes biometric data input from a biometric data input device, a data encryption processing unit that encodes biometric data recognized by the recognition processing unit and information different for each mobile phone, and the above. A mobile phone including a biometric data encoded by a data encryption processing unit and a first communication control unit that directly transmits information different for each mobile phone via a mobile phone network or directly. A lock unit that mechanically locks and unlocks the object to be locked, a personal biometric data storage unit that stores biometric data of the user to be authenticated in advance, and biometric data transmitted from the mobile phone and each mobile phone. Decryption by a second communication control unit that receives different information, a data decryption processing unit that decrypts biometric data from the second communication control unit and different information for each mobile phone, and the data decryption processing unit. The biometric data is the same as the biometric data registered in advance in the personal biometric data storage unit, and the information is different for each pre-registered mobile phone, and the mobile data decrypted by the data decryption processing unit. It is composed of a locking / unlocking device composed of a lock control unit that locks or unlocks the lock unit when different information is matched for each telephone.</p><p> According to the present invention, the mobile phone transmits the biometric information of the user to be authenticated and the unique information different for each mobile phone to the locking / unlocking device, and the locking / unlocking device differs for the biometric information and the mobile phone. Since the authentication is performed based on both the information and the information, even if the biometric information is stolen, it is possible to prevent spoofing by another person. Further, since the mobile phone and the locking / unlocking device can directly communicate with each other not only via the mobile phone line network, it can be used even in a place where the radio wave from the base station of the mobile phone system does not reach.</p><p> As the information different for each mobile phone, the telephone number of the mobile phone may be used, or the serial number of the mobile phone may be used.</p><p> Further, the first communication control unit and the second communication control unit may be directly communicated by wireless LAN or may be directly communicated by infrared communication.</p>

<p> As described above, according to the present invention, the following effects can be obtained. (1) Since authentication is performed using both biometric information and information different for each mobile phone, it is possible to prevent spoofing by another person even if the biometric information is stolen. (2) Since the mobile phone and the locking / unlocking device can directly communicate with each other, it can be used even in a place where the radio wave from the base station of the mobile phone system does not reach.</p>

Next, the keyless lock system according to the embodiment of the present invention will be described in detail with reference to the drawings.

The keyless lock system of this embodiment secures the convenience of the lock system by using the communication function of mobile phones that are widely used in the market, and voiceprint data authentication / fingerprint data authentication / iris authentication / retinal pattern authentication, etc. The present invention is applied to a keyless lock system that secures security by using the biometric data of the above for personal authentication and can lock / unlock the lock of a house or a car safely and easily without using a key. It is applied.

FIG. 1 is a block diagram showing a configuration of a keyless lock system according to an embodiment of the present invention. As shown in FIG. 1, the keyless lock system of the present embodiment includes a mobile phone 10 and a locking / unlocking device 30. The mobile phone 10 and the locking / unlocking device 30 are connected by a mobile phone line network 20.

Further, the mobile phone 10 includes a voice input device 101 for inputting voice data, a video input device 102 for inputting video data, a fingerprint input device 103 for inputting fingerprint data, another biometric data input device 104, and voice. It includes a recognition processing unit 105, a video recognition processing unit 106, a fingerprint authentication processing unit 107, other recognition processing units 108, a data encryption processing unit 109, and a communication control unit (wireless unit) 110. Here, the configuration and the like required for a call on the mobile phone 10 will be omitted.

The voice recognition processing unit 105 performs recognition processing of biological data such as a voiceprint / spoken word from the voice data input from the voice input device 101. The image recognition processing unit 106 performs recognition processing of biological data such as an iris / retinal pattern from the image data input from the image input device 102. The fingerprint recognition processing unit 107 performs fingerprint pattern authentication processing from the fingerprint data input from the fingerprint input device 103. The other recognition processing unit 108 recognizes the biometric data from the data input from the other biometric data input device 104.

The data encryption processing unit 109 encodes biometric data recognized by the voice recognition processing unit 105, the video recognition processing unit 106, the fingerprint recognition processing unit 107, and other recognition processing units 108, and information different for each mobile phone (encryption). To).

The communication control unit (wireless unit) 110 transmits the biometric data encoded by the data encryption processing unit 109 and information different for each mobile phone via the mobile phone network 20 or directly to the locking / unlocking device 30. ..

Here, as the information different for each mobile phone, the telephone number or serial number of the mobile phone can be used. The telephone number and serial number of the mobile phone are unique, and security can be improved by combining such unique information with biometric data.

Then, when the distance to the locking / unlocking device 30 is long, the communication control unit 110 transmits biometric data and information different for each mobile phone to the locking / unlocking device 30 using the mobile phone network 20. When the distance to the device 30 is short, the information may be transmitted directly to the locking / unlocking device 30 by communication via wireless LAN or the like.

As shown in FIG. 1, the locking / unlocking device 30 includes a lock unit 301 that mechanically locks / unlocks an object to be locked, a lock control unit 302, a data decryption processing unit 303, and a communication control unit (wireless). Part) 304 and personal biometric data storage part 305.

The personal biometric data storage unit 305 stores in advance the biometric data of the user to be authenticated, such as voiceprint / spoken word / iris / retina pattern / fingerprint pattern.

The communication control unit (wireless unit) 304 receives the biometric data transmitted from the mobile phone 10 and information different for each mobile phone, and outputs the data to the data decryption processing unit 303.

The data decryption processing unit 303 decrypts the biometric data from the communication control unit 304 by decrypting the information different for each mobile phone, and for each unencoded biometric data and the unencoded mobile phone. Get different information.

The lock control unit 302 matches the biometric data decrypted by the data encryption decryption processing unit 303 with the biometric data registered in advance in the personal biometric data storage unit 305, and is different for each pre-registered mobile phone. When the information matches the information decrypted by the data decryption processing unit 303 for each mobile phone, the lock unit 301 is locked or unlocked. Next, the operation of the keyless lock system of the present embodiment is illustrated. Will be described in detail with reference to.

First, the biometric information of a user having a legitimate authority is stored in the personal biometric data storage unit 305 of the locking / unlocking device 30. Further, the telephone number or the serial number of the mobile phone 10 is stored in the lock control unit 302 as information different for each mobile phone. Here, a case where the biometric data registered in advance is fingerprint data and a telephone number is used as information different for each mobile phone will be described.

Then, from the input devices 101 to 104, the one corresponding to the biometric data registered in advance is selected and the biometric data is input. Here, since the biometric data registered in advance is fingerprint data, the fingerprint data is input by the fingerprint input device 103. Then, this fingerprint data is recognized and processed by the fingerprint recognition processing unit 107 to obtain a fingerprint pattern, and the data of this fingerprint pattern is encoded by the data encryption processing unit 109. The mobile phone number information is also encoded by the data encryption processing unit 109. Then, the encoded fingerprint pattern data and the mobile phone telephone number information are transmitted to the locking / unlocking device 30 via the mobile phone network 20 or directly.

The encrypted biometric data sent wirelessly directly from the mobile phone 10 or sent via the mobile phone network 20 is received by the communication control unit (wireless unit) 304. Then, the data cryptanalysis processing unit 303 decrypts the encrypted biometric data and acquires the information of the unencrypted raw biometric data and the unencrypted mobile phone number.

The lock control unit 302 compares the biometric data transmitted from the mobile phone 10 with the biometric data registered in advance in the personal biometric data storage unit 305. Further, the lock control unit 302 compares the telephone number registered in advance with the mobile phone number sent from the mobile phone 10. Then, the biometric data transmitted from the mobile phone 10 and the biometric data pre-registered in the personal biometric data storage unit 305 match, and the pre-registered telephone number is sent from the mobile phone 10. If the mobile phone number matches, the lock unit 301 is locked or unlocked.

In the keyless lock system of the present embodiment, since the mobile phone 10 is used to transmit information such as biometric data to the locking / unlocking device 30 via the mobile phone network 20, the lock / unlock from a remote location is performed. And even if you forget to lock it, you can lock it from outside.

In addition, even if the child returns home while the parent is out and the child does not have a mobile phone or the child's authentication data is not registered in the keyless lock system, this implementation is carried out. According to the keyless lock system of the form, a child calls a parent's mobile phone from a public telephone or the like, and the parent performs wireless communication (telephone network, etc.) to access the locking / unlocking device 30 to unlock. Safe unlocking can be performed even from a remote location.

In the keyless lock system of the present embodiment, since the authentication is performed by both the biometric information and the information peculiar to the mobile phone, it is possible to prevent spoofing by another person even if the biometric information is stolen.

Further, in the keyless lock system of the present embodiment, since the mobile phone 10 and the locking / unlocking device 30 can directly communicate with each other, it can be used even in a place where radio waves from the base station of the mobile phone system do not reach.
