Abstract
A efficient digital watermarking algorithm is used from a encrypted biometric data.This biometric data is unique to everyone and can be logically owned to prove the ownership to digital media.So in that case we expose biometric as a watermark but it may not be secure hence in this paper proposes the method to encrypt the biometric data by using chaotic secret key to enhance the security.Thus this joint encryption and watermarking scheme helps us to address the ownership of digital media and keeps biometric secured.Arnold transformation is used for encryption and Discrete Wavelet Transform is used for watermarking in the image. Later the biometric extracted based on the watermark after decrypting the biometric was unique and was identified by feature matching algorithm and thus the ownership is proved.
