Abstract: With the proliferation of the internet and rapid
development of multimedia, media distribution and traitor tracing issues have
become imperative and critical.
In this paper, the Digital Rights
Management (DRM) system based on
novel Joint Fingerprinting and Decryption (JFD) scheme is
proposed, which transmit the encrypted image to different customers and makes
each customer decrypt the image into a different copy that contains the customer’s unique information. Till now,
some JFD schemes have been reported, that solves
encryption and fingerprinting simultaneously and has high efficiency, but
several problems still remain to be tackled in JFD, including poor encryption
security, severe fingerprinted image distortion, etc. An improved JFD scheme,
which based on Discrete Wavelet Transform (DWT) of media and collusion
resistant fingerprint encoding, is presented in the paper. The experimental results show that the proposed
scheme is more secure compared with the existing scheme, it obtains good
imperceptibility and robustness. These properties make it a suitable choice for
secure image distribution in real time applications.
