Abstract
A method and system for authentication in a computer system is disclosed. The method and system of the present invention includes registering a biometric template in the computer system, thereafter, verifying the authenticity of the registered biometric template and then comparing the biometric template with a biometric image of the user if the biometric template is authentic. If the user's biometric image matches the biometric template, the computer system will continue to boot.
Claims41
A method for authenticating a user of a computer system, the method comprising the steps of:
- a) registering a biometric template in the computer system;
- b) verifying the authenticity of the biometric template;
- and
- c) comparing the biometric template with a biometric image of the user if the biometric template is authentic.
A computer readable medium containing programming instructions for authenticating a user of a computer system, the programming instructions for:
- a) registering a biometric template in the computer system;
- b) verifying the authenticity of the biometric template;
- and
- c) comparing the biometric template with a biometric image of the user if the biometric template is authentic.
A system for authenticating a user of a computer system comprising:
- a processor running an application program for registering a biometric template;
- means for verifying authenticity of the biometric template;
- a sensor coupled to the processor for allowing the user to enter his or her biometric image into the computer system;
- and
- means for comparing the biometric template with the biometric image of the user if the biometric template is authentic.
A method for registering a biometric template in a computer system, the method comprising the steps of:
- (a) prompting a user to provide biometric information to a computer system via a sensor coupled to the computer system;
- (b) creating a biometric template from the biometric information;
- (c) calculating a biometric template hash from the biometric template by hashing a copy of the biometric template;
- and
- (d) encrypting the biometric template hash.
