APPARATUS AND METHOD FOR PERSONAL IDENTIFICATION

摘要

There is provided by this invention a personal identification card for gaining access to controlled areas or computer systems having a microprocessor combined therein that has stored in its memory personal trait characteristics of the individual user. The microprocessor also has stored algorithms for comparing the personal trait characteristics stored in the card with personal trait characteristics inputted from an external device. Stored algorithms are used to update the personal stored traits. The microprocessor verifies the identity of the user of the card. A security system within the microprocessor protects the stored personal trait characteristics and restricts access to the card.
