A Novel Study on Multi-Tier Biometric Security using digital Watermarking

Abstract: This paper presents multitier biometrics using watermarking algorithms with two levels of security for simultaneously verifying on individual and protecting the biometric template. The fingerprint as unique biometric templates is used as a watermark for digitally signing images linked to the watermark. The image can be used directly for verification and the watermark fingerprint data is used to cross authenticate the individual any attempt to tamper the image will consequently change the watermark embedded within it and create a discord between the embedded watermark and biometric data obtained on verification.
