| 摘 要： | A trusted third party introduced in watermarking protocols would decrease the security and affect the implementation of the protocols. In this paper, a new watermarking protocol with an un-trusted third party （UTTP） was proposed. Based on the idea of all-or-nothing disclosure of secret （ANDOS）, all of the buyer, the seller and the third party didn＇t know the exact watermark, which was embedded in a digital content for tracing piracy. The proposed protocol provided mechanisms to trace piracy and protect customer＇s right. In addition, the problem that a seller colluded with UTTP to frame the buyer, namely, the conspiracy problem, could be avoided.

| Abstract: | A trusted third party introduced in watermarking protocols would decrease the security and affect the implementation of the
protocols. In this paper, a new watermarking protocol with an un-trusted third party (UTTP) was proposed. Based on the idea
of all-or-nothing disclosure of secret (ANDOS), all of the buyer, the seller and the third party didn't know the exact watermark,
which was embedded in a digital content for tracing piracy. The proposed protocol provided mechanisms to trace piracy and
protect customer's right. In addition, the problem that a seller colluded with UTTP to frame the buyer, namely, the conspiracy
problem, could be avoided.
