Identity card, information carrier and housing designed for its application

Abstract

An identity card comprises an easy-to-use, more specifically card-shaped, information carrier provided with an electronically readable memory capable of digitally storing personal user data, including data concerning the user's physical features. The information carrier is installed in and can be removed from an input unit of a housing of comfortable dimensions. The housing has been provided with reading equipment which is capable of reading the personal data stored in the memory of the information carrier. Moreover, the housing has been provided with a screen for representing the data read.

Description

,. By means of a command key 104 installed on the housing for this purpose the various personal data can be checked one by one, so that a relatively small screen will suffice for the representation of all relevant personal data.

The identity card in this example comprises in addition to the first information carrier 107, also a second information carrier 207 which has been provided with a folded sheet 210 suited for making notes. This sheet leaves room for notes by the competent authorities e.g. visa, so that the identity card according to the present invention is also suitable as a valid travelling document. During use both information carriers are collectively entered into the housing which has been designed with the appropriate internal dimensions. The second information carrier also comprises an integral circuit 208 with at least an electronically readable memory. In this memory a unique code has been stored in encrypted form; this code is also present in the memory of the first information carrier. The identity card will only function if the codes in both information carriers 107, 207 fully correspond; in case of any differences this will be represented in the screen 103 as an error code. If desired, the processing unit on the first information carrier 107 may also be programmed in such a way that a faulty second information order to immediately combat any fraudulous attempts.

An electronically readable memory in the second information carrier in itself suffices and it is not necessary to also provide for a central processing unit. In order to save costs, the second information carrier in this case has therefore been designed with an electrically programmable memory only, a so-called PROM, whereas the first information carrier also contains a full microprocessor in order to execute the identity control and activate the screen 103 of the housing.

An identification system to be used in combination with the identity card according to the invention has been schematically represented in FIG. 2 this identification system comprises a central processing unit in the form of a computer 1 which has been connected to both a screen 2 and registration tools in order to register the features, either external or not, of a person to be identified 6. In this example the registration tools comprise a camera 3 and a microphone 4, as well as a sensor 9 by means of which a fingerprint can be read. In addition to this, a terminal unit 5 has been connected to the computer 1.

In order to identify a person 6, this person's picture is recorded with a camera 3 and this person's voice is recorded with a microphone 4. Moreover, a fingerprint a taken electronically by means of the sensor 9 and then digitised. The analogue signal which is emitted from microphone 4, is digitised and analysed by computer 1 after which the digital voice data are sent to terminal unit 3. The picture registered by the camera, whether or not processed, is sent by the central computer 1 to terminal 5 in a similar fashion. In this case, a digital camera 3 is assumed, but within the framework of the invention an analogue camera may just as well be applied in which case its picture is digitised by means of well-known techniques such as a frame grabber in combination with an analogue-digital converter.

The person to be identified 6 has an identity card according to the invention consisting of a card-shaped information carrier 7 of handy credit card dimensions, of the type as referred to above. The information carrier 7 has been manufactured from synthetic material and contains an integral circuit linked to an electronically readable memory. Such a carrier is generally referred to ass as a chip card, smart card or similar names. The memory of the card 7 contains the personal data of the user 6 recorded in digital form, including data concerning the physical features and in this case, in addition to a digital passport photograph and personal data, the user's voice and fingerprint as well. The information carrier 7 is manually entered into the slot of the terminal unit after which the data from the computer 1 are transferred to the card 7. These data are processed in the card by means of the integral circuit and compared to the stored personal characteristics. To this end, the integral circuit comprises a central processing unit which is activated by an appropriate program code which is loaded onto the card from the memory. In addition to this. the circuit comprises reading equipment in order to read the personal data stored in the memory of the card. Thus card 7 comprises all means for fully executing the actual identification on the card itself. The results of the identification procedure may be represented visually, e.g. on screen 2, acoustically or both acoustically and visually. Screen 2 may also serve to represent the user's passport photograph 6 as read from card 7, so that the controlling officer of service is also able lo execute a manual identification control.

For that matter, the various personal data of card holder 6, such as name, address and permanent domicile or place of residence, as well as birth register data, eye colour, length, etc., possibly in combination with a passport photographs may, in addition to registration in the card's memory, of course also be registered on the card 7 in the conventional Away way enabling a quick identity control of the user on the basis of these data. Furthermore, the card may also be provided with e.g. an indication of the country or company, whether or not in combination with the according logo and authenticity features, such as for instance particularly a hologram or characters punched into the card, in order to combat forgery.

The personal data in the card's memory 7 comprise various characteristic external features in parameters, particularly concerning the user's external features 6, in order to minimise the influence of cosmetic changes in the user's external features 6 and to enhance the processing speed. These features may include the eye to eye distance, the enclosed (tri)angle between eyes on the one hand, and nose, mouth or chin on the other hand, the relative position of the ears and the like. Characteristic features like these are not or hardly influenced by the use of make up changing beard or hair growth, glasses and other cosmetic external changes which often considerably hinder a conventional identification.

In order to protect the stored personal data, especially in the case of loss or theft, the card 7 can be linked to a unique access code which the user 6 is to enter first before identification takes place and the personal data are made accessible. Entering this access code may take place by means of the key board 8 of the computer unit 1 or the system may be expanded with a separate input unit designed for this use. For increased protection the personal data are stored in encrypted form so that the data cannot be read outside of the integral circuit of the card. The present-day encryption techniques allow for encryption which is so adequate that decoding without knowledge of the encryption key applied is virtually impossible.

In this way the invention provides for a highly efficient and reliable identification system, using an identity card according to the present invention which can be applied on a large scale, not only as official travelling documents such as a passport, driving licence, visa, etc. but also within secured institutions such as company premises and, last but not least, military premises.

Although the invention has been clarified by means of this exemplary embodiment only, it goes without saying that the invention is by no means restricted to this one embodiment. On the contrary, many variations and embodiments can be realised by an average professional in this area without him being required to go beyond the scope of the invention. If desired, the invention may in this way be expanded by further registration tools in order to establish features, whether or not external, of the person to be identified, or the registration tools may, for instance, be restricted to only a camera or sensor (system) in order to record the picture, the fingerprint or eye characteristics. Instead of a more advance chip card, it is also possible to use, less complex card-shaped or otherwise shaped body as information carrier which, however, may contain a memory which can only be read by means of the terminal. Processing and comparing the to personal data will in this case entirely take place outside of the card itself, e.g. in the system's central computer unit as described above.

The data transfer in the terminal may take place by means of physical contact between the electrical contacts on the card on the one hand and in the terminal on the other hand. However, it is also possible to transfer the data without the contacts., in which case the transfer for instance, takes place optically, by means of radiography or induction.

The invention may also be applied more broadly than within the strict sense of person identification only, which use is restricted to obtaining the user's identity. The invention may for instance be incorporated in credit cards, cash cards and the like, for the purpose of verifying the data of its rightful user. To this end, the card in question will not only be equipped with data and/or software enabling the desired payments to be made, but also with digital personal data and characteristics in accordance with the invention. If the card is used, the identity of the user will then be determined, e.g. on the basis of a scan or the fingerprint or a recording of the external characteristics, and the payments can only be made after this has been electronically confirmed. In this way the invention provides for a virtually fraud-proof means of payment, which, among others, is not susceptible to loss or theft and the like. More over the identity card according to the present invention can also be programmed in such a way that it is suited as multiple identity card for various environments, For for instance as travelling document, driving licence, and proof of access for one or more company premises or events. Moreover,the Moreover, the housing of the identity card according to the present invention is not restricted to the example given. It may for instance be expanded by a sound generator in order to enable an audio, or even spoken representation or signaling. One may also apply a more sophisticated screen in order to e.g. fully represent a passport photograph stored in the memory of the information carrier. In addition, the single command key may be replaced by a number of similar keys or even a full numeric or alphanumeric key board for the purpose of making the control of the identity card even more comfortable.

In short, the invention provides for an intelligent identity card which has no or hardly any restrictions when it comes down to ease of operation, protection against fraud and usability.
