Remote authenticating biometric apparatus and method for networks and the like
First Claim
1. A method for authenticating a user over a network comprising the steps of:
- a) sending a random number from a remote site to a local site of a user, b) measuring a first biometric parameter from said user with a biometric reader, c) comparing said first biometric parameter with a previously stored second biometric parameter, d) operating on said random number with a math table to create a first cryptogram when a positive match occurs between said first and second biometric parameter, e) sending said first cryptogram from said local site to said remote site for comparison with an internally generated cryptogram.

Abstract
A secured biometric apparatus and method for authenticating only authorized users into secured networks where sensitive information is located and stored. The method having the steps of sending a random number from a remote site to a local site of a user, measuring a first biometric parameter from the user with a biometric reader, comparing the first biometric parameter with a previously stored second biometric parameter, operating on the random number with a math table to create a first cryptogram when a positive match occurs between the first and second biometric parameter, sending the first cryptogram from the local site to the remote site for comparison with an internally generated cryptogram.

7. A method for authenticating a user over a network comprising the steps of:
-
a) sending a random number from a remote site to the site of the user, b) measuring a biometric parameter from said user with a biometric reader, c) comparing said first encrypted biometric parameter with a second encrypted biometric parameter previously stored on said biometric reader, d) generating a second random number when said first encrypted biometric parameter does not positively match said second encrypted biometric parameter, e) operating on said second random number with a math table to create a first cryptogram when a positive match fails to occur between said first and second biometric parameter, f) sending said first cryptogram from said local site to said remote site for comparison with an internally generated cryptogram. - View Dependent Claims (8, 9)
