On the Possibility of Non-Invertible Watermarking Schemes (2004)
Recently, there are active discussions on the possibility of non-invertible watermarking scheme. A non-invertible scheme prevents an attacker from deriving a valid watermark from a cover work. Recent...
Proactive Secret Sharing with Low Bandwidth and Fine Granularity (2003)
Qiming LI, Charng Rang GUO, Ee-Chien CHANG
We consider (K,N) proactive secret sharing schemes whereby a large number of secrets are shared by N servers, and the secrets are reconstructible from shares in any K servers. The schemes are...
Public watermark detection using multiple proxies and secret sharing (2003)
Abstract. A central issue in public watermarking schemes is the design of a detector that will not reveal sufficient information that leads to the erasure of embedded watermark, even if an adversary...
