Abstract

Plastic cards for different types of stored data are in wide use at present. Examples are credit cards and cards bearing access control information for automatic teller machines. More powerful devices with non-volatile read/write memory of several kilobytes, possibly with some intelligence, (Personal Data Cards), open new fields of applications in banking, administration, health care and communications.

If sensitive data is stored on such cards, protection of this data and authentication of the authorized user becomes crucial. This paper describes a method for user verification and selective record protection in a network of terminals and one or more trusted Authentication Servers. The method is based on Single Key and/or Public Key Cryptography in conjunction with personal feature recognition (such as fingerprints) and selective key distribution. All the system information that needs secrecy protection is one key in the Authentication Server(s). The reference pattern for the feature recognition is stored on the card in encrypted form. The Authentication Server(s) can be kept very simple and inexpensive since no long-term data storage is required. As no user specific information remains permanently in the terminals, full user mobility is assured.
