First Claim
1. A card, comprising:
- a substrate having first and second opposite sides,at least one biometric data entry device on said first side of said substrate to receive biometric data about an individual engaging with said at least one biometric data entry device;
at least one memory component on said substrate and containing biometric data about an individual authorized to use the card and at least one private key;
a processor configured to compare biometric data received via said at least one biometric data entry device to biometric data contained in said at least one memory component to determine whether they match and when they match, initiate a process requiring use of the at least one private key for authorized use of the card;
a chassis intrusion detector system that detects tampering with the card and upon such detection, causes erasure or deletion of the at least one private key in said at least one memory component to thereby prevent unauthorized use of the card,said chassis intrusion detector system comprising conductors spaced apart from each other over both said first and second sides of said substrate,said conductors being electronically connected together to form a transmission line, whereby breaking of one of said conductors causes variation of current through the transmission line,said processor being configured to erase or delete the at least one private key upon detecting a variance in current through the transmission line defined by said conductors caused by breaking of one of said conductors; and
a protective cover comprising;
a top cover on said first side of said substrate over a portion of said chassis intrusion detector system on said first side of said substrate, said top cover including a respective opening aligning with said at least one biometric data entry device, anda bottom cover on said second side of said substrate over a portion of said chassis intrusion detector system on said second side of said substrate such that said substrate and said chassis intrusion detector system are between said top and bottom covers.

Abstract
Card including a substrate, at least one biometric data entry device on the substrate to receive biometric data about an individual holding the substrate, a memory component on the substrate and containing biometric data about an individual possessing the card and at least one private key, and a processor configured to compare biometric data received via the biometric data entry device to biometric data contained in the memory component to determine whether they match. When there is a biometric data match, a process requiring use of the private key(s) is initiated for authorized use of the card. A chassis intrusion detector system detects tampering with the card and upon such detection, causes deletion of the private key(s) to thereby prevent unauthorized use of the card.

16. A method for validating use of a card by an authorized user, comprising:
-
prior to use of the card, placing biometric data of the authorized user into at least one memory component on the card along with at least one private key required for authorized use of the card, the at least one private key being contained in the at least one memory component on the card; receiving via at least one biometric data entry device on a first side of a substrate in the card, biometric data about an individual engaging with the at least one biometric data entry device, the substrate having a second side opposite the first side; comparing, via a processor on the card, biometric data received via the at least one biometric data entry device to biometric data contained in the at least one memory component to determine whether they match and when they match, initiating a process requiring use of the at least one private key for authorized use of the card; enclosing the substrate with a chassis intrusion detector system that detects tampering, the chassis intrusion detector system comprising conductors spaced apart from each other over the first and second sides of the substrate; covering the chassis intrusion detector system with a protective cover; and periodically determining whether the chassis intrusion detector system has detected tampering and if so, erasing or deleting the at least one private key to thereby prevent authorized use of the card, the protective cover including a top cover on the first side of the substrate over a portion of the chassis intrusion detector system on the first side of the substrate, the top cover including a respective opening aligning with the at least one biometric data entry device, and a bottom cover on the second side of the substrate over a portion of the chassis intrusion detector system on the second side of the substrate such that the substrate and the chassis intrusion detector system are between the top and bottom covers. - View Dependent Claims (17, 18, 19, 20)
