Apparatus and methods for verifying identity using biometric information collected during a pre-enrollment phase
First Claim
1. A method comprising:
- during a pre-enrollment phase collecting a plurality of samples of at least one biometric measure from an individual;
saving the plurality of samples of the at least one biometric measure;
deciding that an enrollment phase may be initiated upon detecting satisfaction of at least one predetermined criterion;
informing the individual who provided the samples of the at least one biometric measure collected during the pre-enrollment phase that the individual may proceed with the enrollment phase;
upon activities associated with the enrollment phase being initiated, discontinuing the pre-enrollment phase;
prior to or during the enrollment phase, retrieving the plurality of samples of the at least one biometric measure collected from the individual;
during the enrollment phase selecting valid samples of the at least one biometric measure from the plurality of samples collected from the individual, where the valid samples reflect statistically significant variations in the at least one biometric measure;
generating, by a biometric measure authentication model generation apparatus, an authentication model of the at least one biometric measure using the valid samples of the at least one biometric measure; and
using the authentication model of the at least one biometric measure to authenticate a sample of the at least one biometric measure provided during an identity verification even by a person claiming to be the individual who provided the plurality of samples of the at least one biometric measure collected during the pre-enrollment phase.

Abstract
Apparatus and methods are disclosed for verifying identity using a plurality of biometric samples collected during a pre-enrollment phase, where the plurality of biometric samples concern one or more biometric measures. In one embodiment, the biometric measure comprises an individual'"'"'s signature, samples of which are collected over a period of time prior to an enrollment procedure. Collecting signatures over a period of time prior to an enrollment procedure allows a more robust signature model to be developed since the signature model will reflect natural, statistically significant, variations that occur over time. During an enrollment procedure, the user then attests to the validity of the signatures collected during the pre-enrollment phase. Valid signatures are used to construct a signature model that will be used to authenticate signatures provided during later transactions. Apparatus and methods of the invention additionally encompass collecting biometric samples of other biometric measures such as, for example, facial appearance, during a pre-enrollment phase.

19. A memory tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus of a computer system to perform operations for verifying identity of an individual using at least one biometric measure, the operations comprising:
-
during a pre-enrollment phase, collecting from an individual a plurality of samples of the at least one biometric measure; storing the plurality of samples of the at least one biometric measure in a database; deciding that an enrollment phase may be initiated upon detecting satisfaction of at least one predetermined criterion; informing the individual who provided the samples of the at least one biometric measure collected during the pre-enrollment phase that the individual may proceed with the enrollment phase; upon activities associated with the enrollment phase being initiated, discontinuing the pre-enrollment phase; retrieving the plurality of samples of the at least one biometric measure from the database; during the enrollment phase receiving input identifying certain samples contained in the plurality of samples of the at least one biometric measure as valid samples; detecting an identity verification event involving a person claiming to be the individual who provided the plurality of samples of the at least one biometric measure during the pre-enrollment phase; receiving a sample of the at least one biometric measure provided during the identity verification event by the person; and using the valid samples of the at least one biometric measure to authenticate the sample provided by the person during the identity verification event, wherein authentication of the sample verifies that the person providing the sample of the at least one biometric measure during the identity verification event is the individual who provided the plurality of samples during the pre-enrollment phase, where using the valid samples of the at least one biometric measure to authenticate the sample further comprises generating, by a biometric measure authentication model generation apparatus, a biometric measure authentication model using the valid samples, and using the biometric measure authentication model to authenticate the sample provided during the identity verification event. - View Dependent Claims (20, 21)
