%X We
propose a novel biometric sensing technique for personal authentication in
which fingerprint images are captured using an optical encryption method. This method
can reduce the risk of data theft or leakage of personal information captured
by biometric sensing. This method, termed encrypted sensing, is implemented
using digital holography with double random phase encoding. We demonstrate
experimentally that a fingerprint image can be captured as an optically
encrypted image and can be restored correctly only when the correct cipher key
is used. Moreover, we investigate experimentally the verification accuracy of
the decrypted images.
