System, method and apparatus for electronic authentication
First Claim
1. A method for authenticating a user, comprising:
- receiving, at an authentication server, identification data from an authentication device;
generating random data at the authentication server;
combining the random data and the identification data to map at least two data points; and
determining a geometric curve that includes the at least two data points;
wherein an authentication decision is based on one or more characteristics of the geometric curve.

Abstract
A system, method and apparatus for on-line authentication of a user. The system may include an authentication device, such as a portable authentication token, in communication with an authentication server or system of a trusted party. In one aspect, authentication is based on an authentication curve or data derived from it, the authentication curve being mapped from points that are based on a combination of unique data stored or obtained by the authentication device and provided to the authentication server, and on information stored or obtained at the authentication server. In one embodiment, authentication is based at least in part on biometric data of a user to be authenticated.

6. A method for reaching a positive or negative determination of authentication in response to a request by an unknown user, comprising:
-
reaching a positive determination of authentication only when;
data received from the unknown user are combined with data stored to determine a curve, the curve having a unique mathematical property; and
the unique mathematical property matches a stored mathematical property associated with a known user;
wherein the unique mathematical property is permanently associated with the known user; and
wherein the curve having the unique mathematical property cannot be calculated from the data stored alone. - View Dependent Claims (7, 8, 9)
