Abstract
Subject matter disclosed herein may relate to a biometric security technique, and may relate to biometric identity verification and emotional stress state evaluation.
Claims21
A biometric security method, comprising:
- generating a plurality of test keyboard metrics from a received identity verification request;
- comparing a typing pattern expressed in the received identity verification request with those expressed in a one or more stored entries from a plurality of registered users;
- refusing access to a controlled resource in the event the typing pattern expressed in the received identity verification request does not substantially match any of those expressed in the stored entries, and, in the event the typing pattern expressed in the received identity verification request does substantially match the or each typing pattern expressed in a one or more of the stored entries, determining a closest matching registered user whose typing pattern most closely matches that expressed in the received identity verification request;
- comparing the test keyboard metrics with a one or more stored keyboard metrics associated with a normally stressed state of the closest matching registered user;
- and
- allowing access to the controlled resource in the event the typing pattern expressed in the test keyboard metrics substantially matches that associated with a normally stressed state of the closest matching registered user.

A biometric security system, comprising
- a keyboard metric calculator to generate a plurality of test keyboard metrics from a received identity verification request;
- an identity comparator to determine whether a typing pattern expressed in the received identity verification request substantially matches a typing pattern expressed in a one or more stored entries from a plurality of registered users, and in the event the typing pattern expressed in the received identity verification request substantially matches a plurality of the typing patterns expressed in the stored keyboard metrics, establish a closest matching registered user whose typing patterns, most closely match that of the received identity verification request;
- a stress state comparator to compare the test keyboard metrics with a one or more stored keyboard metrics associated with a normally stressed state of the closest matching registered user;
- an access controller to refuse access to a controlled resource in the event the typing pattern expressed in the received identity verification request does not substantially match any of the typing patterns expressed in the stored entries and in the event a match is found, to allow access to the controlled resource in the event the typing pattern expressed in the received identity verification request substantially matches that associated with a normally stressed state of the closest matching registered user.
