PERSONAL IDENTIFICATION SYSTEM FOR ELECTRONIC LOCKS AND OTHER COMPUTER SYSTEMS

摘要

The invention relates to a personal identification system for electronic locks and other computer systems. The system basically enables an individual to identify himself before a great variety of locks (and also enables him to use them mechanically), computer systems or services provided therein by using a single element resembling a house or car key. The system comprises a (personal) key and a lock (in the system that provides the service), both of which are electronic. One of the two elements may not have its own autonomous power supply. When the key is inserted in the lock, a series of contacts between these two elements is activated. Some of these contacts make it possible for the element that does not have its own power supply to be supplied by the other. Other contacts make it possible to transfer data between the two elements. These contacts make it possible for the key and lock to identify one another in a biunivocal and exclusive manner using, for example, an asymmetric key system. Once identification has occurred, both interlocutors with act accordingly.
