ABSTRACT
Digital watermarking is a technology to hide information in
digital media. We extend the digital watermarking technique
PhasemarkTM, originally developed solely for image
authentication, to biometrics to assist in forensic analysis. Using a
signature extracted from the Fourier phase of the original image,
we hide an encoded signature back into the original image
