System and Method for Fingerprint Validation

摘要

The invention provides a system and method for rapid validation of identity from tissue using registered two dimensional and optical coherence tomography (OCT) scan images. The preferred embodiment provides, for a human fingerprint, validation that the surface fingerprint matches the primary fingerprint. An alternate embodiment provides validation of “aliveness” by ascertaining blood flow. Various embodiments are taught.

1. A method of validating a fingerprint, said method comprising:
selecting a relative positioning of an optical coherence tomography system and a surface imaging device, with respect to each other; performing an optical coherence tomography scan to produce at least one cross sectional tomographic scan of said fingerprint, said scan including the interface of the epidermis and the dermis; obtaining a surface image of said fingerprint; validating, by comparing said cross sectional tomographic scans of said fingerprint with said surface image of said fingerprint, that said cross sectional tomographic scan is compatible with the corresponding region of said surface image; outputting result of said validation step.
