Method for biometric encryption of email
First Claim
1. A method for exchanging electronic messages between a sender with an enrolled biometric feature set and a receiver with an enrolled biometric feature set, comprising:
- a. exchanging enrolled biometric feature sets between the sender and receiver;
b. generating a live-scan biometric feature set of the sender;
c. generating a first difference key derived from the difference between the sender'"'"'s live-scan biometric feature set and the sender'"'"'s enrolled biometric feature set;
d. encrypting the message with the first difference key;
e. encrypting said sender'"'"'s live-scan biometric feature set with an encryption key;
f. transmitting to the receiver the encrypted message and said encrypted sender'"'"'s live-scan biometric feature set;
g. decrypting by the receiver said encrypted sender'"'"'s live-scan biometric feature set;
h. regenerating by the receiver the first difference key by calculating the difference between said sender'"'"'s live-scan biometric feature set and the sender'"'"'s enrolled biometric feature set;
i. decrypting the message by use of the regenerated first difference key.

Abstract
A method for permitting the secure transmission of electronic messages by using biometric certification is provided. Enrolled fingerprint feature sets, which have been uniquely modified for a particular person with whom messages will be exchanged, are cross-enrolled between the sender and receiver such that the biometric identity of both the sender and receiver can be checked during message sending and receiving. In one embodiment, the sender provides a live-scan fingerprint feature set which is subtracted from the enrolled fingerprint feature set of the sender to create a “difference key” or “difference key” that is used to encrypt the message and other fingerprint data. The receiver decrypts the sender'"'"'s live-scan fingerprint feature set that is then used to reconstruct the difference key, which is then used to decrypt the message.
