MITIGATION OF COLLUSION ATTACKS AGAINST WATERMARKED CONTENT |
摘要 |
Media content containing a substantially invisible watermark and/or a fingerprint may be redistributed/retransmitted in a way that bypasses bypass the detectability of a hidden or invisible watermark or fingerprint. In particular, a first segment of media content may be received by a first receiver and a second segment of media content may be received by a second server. The first and second segments may be stored on a storage device. The first and second segments may be made available to a client in the form of a concatenated media content. |
