Chu presented a Multicast Watermark Protocol, however, did not provide the schemes by which the fingerprint can be coded, so from the theoretical point of view, there does not exist the foundation for leaker identification and being collusion free, Furthermore, from the practical point of view, MWP cannot identify the leaker and be collusion free in the case of smaller amount of raw data.

Chu提出了一个多播水印协议MWP ，但没有研究如何进行指纹编码，因此在识别泄漏者、抵御合谋攻击方面缺乏理论依据，并且从实践的角度看，在原始数据量较小的情况下，MWP不能识别泄漏者，也不能抵御合谋攻击。
