Claim One:
1. A method for verifying a user's identity from a test biometric image obtained from the user, the method comprising: (A) comparing the test biometric image provided by an imaging device with reference biometric data stored in a reference database, wherein the reference biometric data comprises a plurality of reference biometric images of different portions of a surface of an organic tissue of the user, wherein each reference biometric image partially overlaps at least one other reference biometric image, and wherein the reference biometric data further comprises relative location information between each reference biometric image and at least one other reference biometric image, and wherein comparing the test biometric image with reference biometric data comprises using a matching algorithm to compare the test biometric image with each of the reference biometric images to identify matching reference images having overlapping data with the test biometric image; (B) determining spatial correspondence between the test biometric image and each of the matching reference images identified in step (A); (C) determining spatial correspondence between each of the matching reference images identified in step (A) based on the spatial correspondence determined in step (B); and (D) comparing the spatial correspondence determined in step (C) with the relative location information of the reference biometric data.
