Samsung patents biometric check that adjusts for hidden data shifts
This filing describes a method for verifying a user's identity by comparing live biometric data against stored records. It applies a mathematical change to both sets of data and calculates multiple similarity scores using different internal settings to decide if the match is valid.
In the filing’s own words
In one embodiment, a method includes accessing query biometric data associated with a verification request for a user. The method further includes applying a transformation to the query biometric data to generate a transformed query template representing the query biometric data and accessing a transformed enrollment template comprising transformed enrollment biometric data of the user. The method further includes determining, based on a scoring function comparing the transformed query template and the transformed enrollment template, a plurality of similarity scores, each similarity score associated with a different value of a scoring parameter; and determining, based on the plurality of determined similarity scores, whether to grant or deny the verification request.
What exactly they claim (claim 1)
1. A computer-implemented method comprising: accessing query biometric data associated with a verification request for a user; applying a transformation to the query biometric data to generate a transformed query template representing the query biometric data; accessing a transformed enrollment template comprising transformed enrollment biometric data of the user; determining, based on a scoring function comparing the transformed query template and the transformed enrollment template a plurality of times, a plurality of similarity scores, wherein: the scoring function comprises (1) one or more explicit parameters and (2) one or more latent parameters, each latent parameter having a value that is not directly measured; each similarity score of the plurality of similarity scores is based on the one or more explicit parameters and the one or more latent parameters; and each similarity score is associated with a different value of at least one of the one or more latent parameters; and determining, based on the plurality of determined similarity scores, whether to grant or deny the verification request.
