    Abstract: The legality of redistribution of digital content over
    the Internet has become critical in commerce. The goal of the
    traitor tracing problem is to find out the traitor who illegally
    distributes the digital content. In this paper, a joint
    fingerprinting and decryption (JFD) scheme based on vector
    quantization and bipartite matching for traitor tracing is
    proposed. Before transmission, the proposed method encrypts
    the VQ compressed image through bipartite graphs. After the
    receiver performs decryption and fingerprinting, the recover
    image containing user’s fingerprint is only slightly different
    from the original one and can be used for traitor tracing. The
    experimental results show that the encrypted image possesses
    unintelligibility and the recovered image has desirable image
    quality greatly related to the codebook size.
