传统的数字水印系统假设分发者（服务器）是完全可靠的组织。如果服务器不是可靠的组织，则在传统系统中，怀疑可能落在没有非法分发的用户身上。已经提出了几种方法来处理这个问题。然而，在这些方法中，系统基本上由两种实体组成：代理和用户。没有讨论由三个实体-作者、代理和用户-组成的系统，其中二次分发发生在从作者到代理，然后到用户。本文提出了一个数字水印系统，可以防止非法行为的二次分发系统组成的三种类型的实体-作者，代理人和用户。© 2003威利期刊公司Electron Comm Jpn Pt 3，86（6）：76-85，2003;在线发表于Wiley InterScience（www.interscience.wiley.com）。DOI 10.1002/ecjc.1151
Conventional digital watermark systems assume that the distributor (server) is a completely reliable organization. If the server is not a reliable organization, in a conventional system it is possible that suspicion may fall on a user who is not illegally distributing. Several methods have been proposed to handle this problem. In these methods, however, the system is essentially composed of two kinds of entities: the agent and the users. There is no discussion of a system composed of three entities—authors, agent, and users—where secondary distribution takes place from the author to an agent and then to the users. This paper proposes a digital watermark system that can prevent illegal conduct in a secondary distribution system composed of three types of entities—authors, agent, and users. © 2003 Wiley Periodicals, Inc.
