Abstract:
1. Computer-readable medium having a database of a plurality of unique transaction security codes, each transaction security code comprising a transaction code and a unique biometric security code which is appended to the transaction code, the transaction code being generated from a commercial transaction of a user and the unique biometric security code being determined from a unique biometric sensor code generated from a biometric presentation of a finger of the user to a fingerprint sensor, the uniqueness of the biometric sensor code resulting from an inherent uniqueness in the biometric presentation which results from an inherent variation of one or more of a group consisting of the amount of pressure exerted by the user on the fingerprint sensor, lateral rotation of the finger, longitudinal rotation of the finger, and other variation in the biometric presentation of the finger to the fingerprint sensor, and a resolution of the fingerprint sensor, the transaction security code being statistically irreproducible, a subsequent presentation of the finger by the user not generating the same biometric security code, the uniqueness of the biometric security code and the resultant uniqueness of the transaction security code providing for a check against other transaction security codes in the database to detect any attempted fraudulent reuse of a biometric security code for a prior commercial transaction in the database.
