Definitions

• the invention relates to identification cards, such as those used in a variety of forms and configurations at banks, in trade and in industry. Examples of such cards are: identity cards, check cards, credit cards, authorization cards for locking systems, safes, etc., other security papers, savings books, certificates.
• a fingerprint of the cardholder is printed on the credit card.
• the natural fingerprint of the cardholder is compared with the print on the card. Even fingerprints are not forgery-proof and can be copied and copied together with the credit card.
• an identification card is described on which a person's fingerprint is stored in coded form.
• This saved Fingerprint is encoded with a characteristic coding key derived from this fingerprint according to a predetermined rule. Only if there is a match between the natural fingerprint and the fingerprint encoded on the identification card, is a Freiga-approved.
• the effort for coding and decrypting and comparing the coding is not insignificant.
• the object of the invention is an identification card which enables coding and checking in a simple manner and which cannot be used by a third party in the event of theft or loss.
• a method for coding identification cards by means of fingerprints in which a plurality of fingerprints are taken from a fingerprint sensor by the cardholder. From the fingerprints taken, an imprint as a key code is applied to the identification card and after one Scrambling key is selected and stored at least one of the other fingerprints as the identification code.
• all fingers of both hands including the thumb for generating the key code and the identification code, are removed by a fingerprint sensor.
• a fingerprint sensor For many people who use the card little, and especially for older people, this has the advantage that they do not need to remember which fingers the impressions were made with during coding.
• the cardholder does not need to know the fingerprint selected as the key code. He's going for one Above all, laypeople cannot be realized if only a certain part of the fingerprint is used as coding. Knowing the finger from which the key code originates is of little value even for an unauthorized person, since it is only the key code that does not yet allow the identification card to be used.
• the key coding is carried out only by pressing certain fingers. If this form of coding is combined with a measure known per se, which makes the card unusable if the key coding does not match the natural fingerprint, a further security level is installed.
• the identification code can consist of a single fingerprint or of several. Multiple fingerprints increase security. Given the difference in fingerprints, a single impression is also completely sufficient.
• the method for identifying an identification card encoded according to one of claims 1 to 4 consists in that a plurality of fingerprints are taken from the cardholder by means of a fingerprint sensor, that the fingerprints taken have the key code - fingerprint on the identification card are compared and, if a natural fingerprint matches the key code - fingerprint of the identification card, a memory is opened is that the fingerprint selected and stored according to a scrambling key is compared with the natural fingerprints taken and that if one of the natural fingerprints taken matches the stored fingerprint, a release signal is given.
• This identification method is simple to carry out and requires only a relatively small amount of equipment at the location of the identification card. If one considers that the annual volume of credit card fraud alone amounts to 100 million marks in Germany, the advantage of the double-secured fingerprint identification card according to the invention is considerable. Professionals use a card to damage up to 100,000 marks.
• the cardholder pushes his identification card into a fingerprint acceptance and comparison device and places a plurality or all of the fingers of both hands on the fingerprint sensor.
• the sensor surface is arched, so that all fingers including the thumb come into contact well.
• a memory is opened by means of a signal which contains the fingerprint of the cardholder selected according to a scrambling system.
• This memory can be a local terminal at the location where the card is used.
• a central terminal that is connected online to the fingerprint acceptance and comparison device at the place of use is more advantageous.
• an identification card can be provided with at least one further key code fingerprint. A corresponding identification code fingerprint is then assigned to this in the memory.
• Such cards are useful if several people use the card for the same purpose at different times. The number of cards issued is thereby kept low.
• Such an identification card can also be used instead of an easily forged proxy for e.g. Cash withdrawals are used.
• An advantageous embodiment of the invention consists in storing the key code fingerprint in a hologram on the identification card.
• the methods according to the invention described can also be used according to the invention for owner identification of paintings, porcelain, valuable prints and other art objects.
• a key code fingerprint is applied to the painting, etc., which can only be removed by removing it.
• the key code imprint on the painting is compared in the same way with a specific ten natural fingerprint of the holder. For double security, a specific natural fingerprint of the holder is then compared with a specific scrambled fingerprint of the holder and stored in a terminal.
• Standard devices can be used as a fingerprint sensor.
• the methods according to the invention can be carried out particularly well if the sensor surface is curved. This means that all fingers, including the thumbs, rest easily and completely.
• a particularly advantageous arcuate configuration consists in a rotatable drum, in particular with a diameter that is sufficient but also large enough for the placement.
• Another advantageous embodiment is a band-shaped transparent film.
• the sensor surface is passed through a cleaning bath after the fingerprints have been removed. This serves, in particular, for the immediate removal of the prints from the sensor surface so that they cannot be removed.
• the fingerprint acceptance and comparison device is arranged in a room, the input of which can be locked immediately by a signal as soon as the key code and / or identification code fingerprints of the user match those of the user legitimate cardholder does not match.
• the additional arrangement of a camera and alarm device supports this measure.
• a drawing of an identification card according to the invention is shown in the drawing. The key code fingerprint is applied at point A.
