Abstract:
A method of creating a personal identification instrument on which personal data and at least one of a picture and signature of a legitimate holder are retained, comprising the steps of:(a) acquiring a first digital representation of at least one of a picture and signature of said legitimate holder of said instrument,(b) extracting first feature data from said digital representation,(c) combining said feature data with said personal data into a single data sequence,(d) generating a security code by encrypting said single data sequence using a private secret key of a kind for which decrypting using a public key would allow authentication of the instrument, and(e) affixing the personal data, and said at least one of a picture and a signature of a legitimate holder and said encrypted security code to the instrument to provide a substantially forgery-proof instrument.
