a: detecting mouse movements of a user;
b: obtaining at least one metric of mouse movement information characterizing the user;
c: comparing the metric against a database; and d: authenticating the user.

2. A method according to Claim 1 wherein the method provides information regarding the user's class identity.

3. A method according Claim 1 wherein the step of detecting the mouse movements of the user is executed without the user's awareness.

4. A method according to Claim 1 wherein the database comprises an aggregated representation of previously detected mouse movement information.

5. A method according to Claim 1 wherein the comparison between the metrics and the database uses at least one eigenvector derived from the metrics.

a database.

9. A system according to Claim 8 wherein a target pattern is used to elicit information known only to an authorized user.

10. A system according to Claim 8 wherein a target pattern that changes from a session to session is used to elicit the user's mouse movements.

11. A system according to Claim 8 wherein said information processing system is distributed over a plurality of networked devices.

12. A system according to Claim 8 is used for online commercial transactions.
