Data carrier and patient card consisting of such a data carrier

The invention relates to a data carrier for storing and Processing digital data and a patient card comprising from such a disk.

There are known to a disk, the only transmission Data are from one computer to another and to other media that the transfer and testing of recording data for access to computer systems and networks serve. While the former only store data, the latter are also able to calculate mathematical algorithms and execute corresponding commands or the execution to deny.

A known data carrier is the so-called Mini Compact Disc, hereinafter referred to as a mini-CD. Fig. Figure 6 shows a Plan view of a mini-CD and Fig. 7 a in the thickness direction greatly enlarged section along the line AA in Fig. 6.

The Mini CD is like the well-known Compact Disc, an optoelectronic Disk. The mini shown in Fig. 6 CD 100 is in contrast to the known CD with a circular Diameter of 120 mm formed in such a way that it has two opposite straight longitudinal sides 101, 102 and these together connecting arcuate narrow sides 103, 104 has. In the center, the mini CD a central bore 105 of circular Cross-section with a diameter d, the so dimensioned is that in the bore of the centering pin of a CDoder can engage the DVD player. The diameter for the players currently used 15 mm. The longitudinal dimension L mini CD is 80 mm and the dimension in the Width B is 63 mm. Thus, the mini CD has a format corresponds to the format of a standard business card.

As can be seen from under the greatly enlarged sectional view of Fig. 7 is is the Mini CD essentially of two structured layers, a first lower layer 106 thin transparent plastic and a laminated thereon Aluminum foil 107 of the highest quality. According to the standardized Preparation of Mini CDs, the thickness of the transparent Plastic layer 0.8 mm and the thickness of the aluminum foil 0.01 mm. The facing of the transparent plastic layer 106 carrying side of the aluminum foil 107 in a known Manner by means of a CD recorder or branded geschriebenden Data. facing away from the transparent layer 106 Side of the aluminum foil is not shown in the figure Plastic protective layer provided. The data are starting from the inner bore 105 of circular outwardly written. Thereby, it is possible to form an asymmetrical in contrast to the earlier conventional records, where the data has been written from the outside inwards, to realize. The only necessity is that the maximum diameter of the mini-CD is not greater than the Diameter of 80 mm an inner recess, as today have CD drive tray.

The storage capacity of the mini CD with the described dimensions is approximately 50MB. There are nurlesbare Mini CDs (CD-ROMs) and rewritable Mini known CDs. In the latter is up to a thousand times cancellation and recall possible.

Due to the high memory capacity, the Mini CD is preferred for advertising applications including complex image sequences, Video films and extensive text documents used. In addition to the massive storage, there are other advantages of the Mini CD is that it is practically readable everywhere because almost each personal computer nowadays a CD or DVD drive having. For computers with the Windows operating system, which is spread throughout the world, is on a view Mini CD no need for a driver software that before inserting the mini CD must be loaded into the computer, since this software already existing part of the Windows Operating system. there is another advantage of the mini CD in the global interoperability since it after inserting - If appropriate programs stored on the mini CD are - can connect the host computer to the Internet. Through this function, the user is hosting on the mini CD and the computer is able, via the global communications to install Internet and perform.

Disadvantages of the mini CD are that this exclusively a storage medium is automatically and no processing power can accomplish, ie only in conjunction with a computer Host that plays Mini CD, programs are executed can.

A second type of data carrier is the so-called Smart Card. Under this Betriff refers plastic cards on a predetermined location having a microprocessor chip. The Figures 8 to 10 show schematically examples of various Smartcards. Fig. 8 shows a smart card 200 in the form of a Contact Smart Card. This consists of a substantially rectangular plastic card 201, in the at a predetermined location a microprocessor chip 202 is embedded, the just above positioned above it and standardized contacts 203 connectable to a corresponding reader for smart cards is to get on the microprocessor chip preprogrammed arithmetic operations perform.

Today, on the market smartcards by ISO 7810 defined in all physical properties.

Fig. 9 shows another example of a smart card 210 in an exploded view, referred to as the contactless smart card becomes. This consists of a card body rear 211 and a front card body 212, between them a microprocessor chip 213 having an antenna coil 214. is connected, including. The antenna 214 is usually as laminated interconnect provided. The connection takes place between the reader and the smart card in this Case wirelessly over a certain radio frequency. If the contactless Smart card in a certain distance, for example, a maximum of 5 meters, moved past the reader, so the smart card transmits to the microprocessor chip stored data to the reader. to increase the performance of the smart card can not, the microprocessor chip only a main processor, but also math co-processors contain. Via the microprocessor chip, data such as conditional access information, such as PIN numbers veroder be decrypted.

Fig. Figure 10 shows a further known embodiment of a SmartCard. The smart card 220 similar to the smart card 200 constructed in accordance with FIG. 8, but additionally includes a fingerprint sensor 221, which is also on the surface on which which are contacts 222 for the microprocessor, laminated is. Instead of entering an access authorization for example in The form of a secret code detects the fingerprint sensor 221 to Fingerprint operator. If the detected fingerprint identical to a fingerprint stored on the chip is replaced by the smart card reader, the information that the User is authorized, or otherwise, that he is not authorized is.

Alternatively, a fingerprint sensor on the smart card Reader even exist.

Smartcards are due to the ability to execute on complex crypto graphical algorithm suitable for access control systems in high security areas, in which the encryption data is of great importance. The scope smart cards is because of this ability to solve highly complex tasks varied. Smart cards are used for credit card systems, access control systems, Ausweisund Identity cards, insurance cards, including patient cards of health insurance, season tickets for public Vehicles and much more.

The great advantage of smart cards as opposed to the previously Mini CDs described is that the smart cards with the microprocessor chip can solve complex computational tasks and therefore include the possibility of the information stored encrypt. Furthermore, the smart cards are for Fingerprint sensor systems or "combo card" applications, such as eg suitable contactless data acquisition.

Disadvantages of the smart card in addition to the compared to the Mini CD small storage volume of data and the limited field of application. For visualization of the on the smart card stored data set or to trigger a desired Calculation is a smart card reader including keyboard required. These readers are technically available, but so far not widely introduced in large numbers. The number of installed smart card readers in relation to CD-ROM drives in personal computers with the operating system Windows is negligible. Another disadvantage is that interoperability and network compatibility is low smartcards. Originally, Smartcards designed so that it distributed with certain Readers communicate, for example, an ATM. A specific smart card is therefore usually on a specific network used, for which it develops has been. For example, a credit card on the basis the smart card technology only in the special information system the credit card company and may be used in this access, but not the same one on the network Hospital system or a car rental company.

So far, it is the manufacturers of smart cards have failed, the Internet to a large extent as a communication network to use. The need for the utilization of a large Communication network such as the Internet has been available in the Application of smart cards and the fact contrary that these mainly decentralized used at certain terminals are, for example, as an access control system for high security areas.

From US 5,790,489 a compact disc is well known, the a has glued in the middle region microprocessor. This constitutes a mechanism for copy protection.

From US 2002/0006103 it is described as desirable to combine a CD disk with a microprocessor chip, but the position of the chip is not defined.

From DE 200 07 767 U1 is a doctor or a patient card known, in which also a microprocessor chip with a CD is combined, wherein the position of the chip is not defined is.

The object of the invention, a data carrier for storing to provide and processing digital data, the Disadvantages of the disk described above is not practical having and is universally applicable and therefore new applications opened.

The object is achieved by the data carrier according to claim 1 and the patient card according to claim fourteenth

The inventive data carrier is now based on figures 1 described to 4. FIG.

The inventive data carrier 1, which also called Smart CD is, is seen in particular in FIG. 3 is built up in layers and comprises of a first layer 2 a plastic on a layer thickness of 0.6 mm, it adjacent second layer in the form of a recorder film 3, for example, an aluminum foil having a thickness of 0.01 mm, and a to these adjoining third layer in the form of a transparent Plastic layer 4 of 0.15 mm thickness. The recorder film 3 facing side of the first layer 2 is completely flat. The first layer 2 is the combination of recorder film 3 and transparent layer 4 by gluing or laminating connected.

As shown in Fig. 1 and 2 it can be seen the outline of which is of from the data carrier layers 2, 3 and 4 similar to those formed 1 the Mini CD shown in FIG. 6. The media has two parallel long sides 5, 6 and two each of these circular arc connecting the narrow sides 7, 8.

The longitudinal dimension L of the data carrier as in the above-described Mini CD 80 mm, the dimension in the width, however, is In contrast to the above-described mini CD only 54 mm, which corresponds to the width of a smart card according to ISO 7816th As in the above described mini-CD is a central 9 hole through all three layers provided through, whose diameter d is the diameter of the well-known mini CD corresponds.

On the recorder film 3 opposite side 2a of the first Layer 2 is at a predetermined position, below the is described with reference to FIG. 4, a recess 10 is formed, in which a microprocessor chip 11 is used and, for example, is secured by gluing. Above the microprocessor chips 11 a contact surface 12 is provided, which in the known of the smartcard way metal terminals 12a, 12b, etc. to be accessed by a reader are formed.

In FIG. 4, on the basis of the outline of a known smart card the predetermined by said ISO standard positions of Contacts of the contact surfaces with respect to the longitudinal sides 5 'and 6 'and the wide sides 7' and 8 'are indicated. Based on the Disk of Fig. 1, the distances to said one transverse side 7 'with respect to a tangent to the curved 7a broadside 7 to measure the volume, which the extension Longitudinal sides 5, 6 at a right angle intersects what is shown by the dashed line in FIG. 1.

2 as is apparent from Fig., Are on the upper Layer 2 remote side of the recorder film 3 D data starting of a distance from the central bore 9 to the outside towards enrolled.

has the above-described layered structure of the data carrier a total thickness of 0.75 mm, which is the maximum thickness of the prescribed by the described ISO standard dimension of Smartcards.

The preparation of the disk is as follows. First is the first layer 2 of the same or similar produced plastic material from which the previous Smartcards are manufactured. The layer 2 is in this case the cut in connection with FIG. 1 described form or punched, or the like. Thus, the first layer 2 is a similar shape as the known CD Mini except that the width B is smaller and a smart card equivalent. In this first layer 2 is at the ISO standard 7816 specified for the smart card body a recess eingefräßt or otherwise attached, in which the microprocessor chip 11 is glued or laminated in such a way that the contact area usually already associated with this 12 oriented outward. The arrangement of the Contact surfaces 12 of the microprocessor chip 11 corresponds to exactly those represented by the ISO standard 7816 for smart card is predetermined.

Then, a combination of the transparent Plastic layer 4 and the bonded thereto recorder film 3, which is also brought to the dimensions shown in Fig. 1 has been glued in such a way with the layer 2 that the film recorder faces 3 of the layer. 2 Then the disk is like the famous Mini CD with a CD burner from the side the transparent plastic layer 4 described. Further is the data memory contained in the microprocessor chip 11 described. Data writing in both the chip as on recorder film 3 may even stick together before of the data carrier take place. The layered structure the recorder film 3 between the layers 2 and 4 protected.

During operation of the media in a CD drive is a read the personal computer and / or described, depending on what kind of recorder film 3 is and what Type is the drive. On the other hand the media may be used in a smart card reader and the microprocessor chip in reads data stored on certain Calculations are performed and / or rewritten data will.

In a further development shown in FIG. 5, the inventive Disk on the top 2a of the first Layer 2 adjacent to the contact surfaces 12 for the microprocessor 11 identification devices on. A first example of Identifying means is a fingerprint sensor 20 for Detecting a fingerprint, the fingerprint detected with in the microprocessor chip 11 or in the compare smart card reading device stored fingerprint is. Another identification device is on the top 2a of the layer 2 provided barcode 21 eg special authentication information includes. As Another example of an identification device is a applied on top of the layer 2a 2 photo 22 or any other label provided. The identification devices described Either alone or in combination be provided together. The bar code 21 and / or any prints or photos 22 are tamper-proof, for example, applied or laminated by a screen printing method. In a modification, on the first layer 2 on the recorder film 3 side facing away from a paper sheet be provided to receive printing.

In operation, the information on the identification device is 20 and / or 21 and / or 22, by read the reader and with predetermined data, for example, are stored in the microprocessor chip 11 or interrogated by the reading device from a remote host computer are compared.

In a further development, instead of the compact disc portion of the data carrier, the transparent film from the recorder 3 and the Plastic layer 4, a DVD-ROM or a DVD-RW Part used, in which case an increase in the storage capacity is from 40 mB to about 4.0 gigabytes possible. In the DVD-RW embodiment, the stored data more than are overwritten 1,000 times.

In a further inventive development is in addition or instead to the existing contact surfaces 12 the microprocessor chip, an antenna conductor in the first Layer 2 laminated. Here, the layer 2 may be in several Layers may be divided. This causes the disk to a contactless Combi Smart CD.

It should be noted that the invention is not limited to the indicated above, described by the current ISO standard Dimensions of the carrier is limited, but also possibly due to changes in standards changed dimensions includes.

Hereinafter, a specific embodiment of the application the inventive data carrier in the form of a patient card described. The microprocessor chip 11 are the Basic information about a patient, such as name, date of birth, etc. is stored, as well as a connection to a central computer, for example, as a central computer for Healthcare for all countries worldwide - for each country or - in the future is common. are on this central computer the medical information about a patient, such as the Medical history, possible treatments, blood group etc. a patient file stored. Similarly, on the CD part, ie stored on the recorder film 3, the basic data of the patient, and access software to the central computer, which when the media is inserted into a CD-ROM or DVD drive a personal computer is activated and the Internet makes access to the central computer. Further the patient receives an identification number.

In operation, the patient puts his patient card with a Doctor visit to the smart card reader of the doctor and enters his personal Idenfikationsnummer. subsequently enabled the media connection to the central computer, where the personal health information has been saved. Thus the doctor immediately of any health-related information the patient informed. Data to the central computer only with appropriate authority of the physician to be changed.

The patient card is, for example, as a pharmacy card usable. are In this embodiment, an application in the central computer of the central patient file Information about the place to be occupied by the patient or also prescribed medicines stored. The Calculator Pharmacist detected the drugs issue and regulate the process warehousing / ordering and billing with the Health insurance.

In a modification of the patient card additionally contains a Fingerprint sensor. In operation, the access to the central is Computer and to the medical file prepared by The patient sets his thumb on the sensor, and the sensor detects the fingerprints and with one in the microprocessor chip compares stored fingerprint. Alternatively contains the patient card a stored in the microprocessor chip digital fingerprint, a fingerprint of over an input to the smart card reader Fingerprint is compared.

The patient card of the invention can for retrieval of patient data from a central computer independent of the used System, such as personal computers with access to the Internet or smart card reader can be used. So is it possible, for example, when a patient outside his Homeland suffers an accident that the accident doctors use patient card and either via the smart card reader the system used in the country, if this matches the system used in the home country, Read the map and so access to patient data have or to the patient records stored in the central computer on the CD portion of the volume of in a personal can computer is used to access. For this purpose, be provided in that the respective user, in this case Asked the Accident physicians after an identification number is, for example, an eight-digit ID number AMA. After this the Authorisierungsvorgang is finished, get the Casualty doctors access to central patient file or -akte of the patient.

The application areas of the disk are not on patient cards limited. The media can in particular Banking and credit card beings are applicable but also for all kinds of trading companies and product manufacturers, since the unique combination of a high-capacity CD and a microchip with large computing power over the prior art is exceptional. More Application areas are identity cards, social security cards and special badges for certain occupations.

In the further embodiment shown in Figures 11 to 14 The invention of the disk 300 in two parts by two rotatably interconnected elements 320 and 340 educated. The microprocessor chip-containing first Element 320 has the dimensions of the smart card forming Layer 2 of the embodiment of FIG. 3. The second Element 340 is a mini-CD with the dimensions of the Mini-CD the layers 3 and 4 of the embodiment of FIG. 3 educated. The two elements 320 and 340 are close to a a corner opposite to the microprocessor chip 11 provided Riveted joint 350 is rotatably connected to each other, so that is a member to the other member pivotally. The elements 320 and 340 are relative to each other arranged such that the microprocessor chip on the first element 320 and the described side of the mini-CD of the second element 340 are on the opposite outer sides. On of the second member 340 facing side of the first element 320, a bar code 360 ​​or a magnetic stripe 361, as shown in Figure 14, may be provided.

The production of the data carrier according to this embodiment is performed such that, to a sticking together of the layers 2 and 3 4, which is done in the first embodiment, dispense is, but the shape expression of the original layers (height x width x thickness) as maintained. Instead of the all-over Bonding of the two layers is at a defined Body mounted in the upper right corner of both cards a bore and then both cards by an unbreakable Plastic rivet is introduced into the Bohnung connected. In this respect are here two disks according to the dimensions gem. Fig. 6 before. Taking these two disks properly matching, as corresponds to the top of the analog SmartCard 2 in Fig. 3 and the other lower, the mini-CD 3, 4 of Fig. 3. The plastic rivet are now both layers a hand to but movable and can be as over open a hinge with a pocket knife or principle swing open. This one gets a flexible dual card, which is readable on the one hand in each CD drive (in folded State) but on the other hand in all smart card readers can be read, the sonsten the previously illustrated not recognize Ausfuehrungsformen.

In operation 11, the data carrier according to FIG. In folded State be read in any CD drive. In the FIG. 12 shown fully unfolded state, the disk with his first, the smart card forming element 320 easily in each smart card reader will be introduced, while the second, the mini-CD-forming element 340 are taken. In the fully unfolded state of FIG. 14 may further one on the bottom of smart card element 320 provided Barcode or magnetic stripe through a compatible device to be read.

The embodiment which forms a flexible combi card, easy to use. You can in a case made of unbreakable Plastics are transported. It has the special Advantage that it is also applicable when smart card readers the older generation are available, in which the embodiment of FIG. 3 may appear on Due to the thickness of the card can not be read.

In the described embodiment can also shown in Fig. 5 modifications which in connection with the first embodiment have been described, may be provided.

connected A further development of CD-health kartenysstems with central or partially decentralized server structures is also the increasing need for data security justice.

Core of the demand of Datenschuetzer is that all health-related Data on the one hand only the sovereignty of the patient may be subject to and on the other hand no one without permission the patient can view this data.

With centralized storage of patient records thus diving two problem levels, on which a threat to data confidentiality could be given. This is one part of the The field of transmission of data by data lines and On the other hand the level of central data storage itself, also hosting the data gennant. By this is meant the central Server computers, where patient records stored centrally are awaiting retrieval.

The further development provides that the patient data already at the point of data entry, namely the doctor's office where the Original file is put together, encrypted or encryptet will. Therefore only enkryptete signals over sent data lines and at the same time only enkryptete Data collections in central hosting server stored. These are unreadable for the host.

If the data is authorized by the patient or a accessed doctor so the enkrypteten data again in an encrypted State of a data line in the computer transported the patient or the attending physician and there decryptet again, that is made readable.

The implementation is such that the patient the CD contains complete De-and Entcryptungssoftware, regardless of other data stored on it. After completion of the New diagnosis is by means of this Encryptungs-software of complete Data content according to the preset by the patient Password verschusselt and encrypteten data in exactly defined patient folders in the central file uploaded. To decrypt it does the opposite, used either the Decryptungssoftware on the CD or a copy the software that is already stored on the respective computer doctor is. The patient enters his password, which he also every time can change and then the patient record encrypted uploaded. The process can be settle very quickly. One requires only a protected Keyboard on the reception desk of the medical reception. interrupted is this system only by the built-in emergency program, which is also stored on the CD or DVD is, if the patient desires. In this case, takes place decryption of stored patient data automatically after an authorized physicians through an online Verification of its Health Professional Card its admission documented to the data. The input from the patient PIN number to decryp- "overwritten" by the emergency PIN number of the physician.

This development is in all embodiments described above, applicable.
