Abstract
The present invention makes it possible for a user to have a security key created from one or more biometric elements of the user, such as a fingerprint. For example, a biometric feature or combination of biometric features of the user can be used to create an instance of a problem which can only be solved by data inherent in the biometric feature or combination of biometric features. The user can supply the data to solve the problem by inputting, through an appropriate input device, an image, or other representation of the biometric elements from which the data that will solve the instance of the problem is derived. If problem is solved, either completely or partially, using the derived data then the identity of the user can either be verified or ascertained. the solution can then be used for other purposes such as the generation of a cryptographic key.
