Card authentication system
First Claim
1. A system for authenticating a data card having an intrinsic magnetic characteristic and recorded data on the data card, the system comprising:
- a reader configured to read information from the data card, the data card information comprising the intrinsic magnetic characteristic and the recorded data;
a network coupled to the reader;
a scoring server coupled to the network, the scoring server configured to;
receive a portion of the data card information encrypted, the portion comprising at least the intrinsic magnetic characteristic of the data card;
decrypt the portion; and
generate a score indicative of a degree of correlation between the intrinsic magnetic characteristic of the received data card information and a stored value; and
a second server coupled to the network and configured to determine an authenticity of the data card based at least in part on the score,wherein a location of the scoring server is different from a location of the second server.
