摘　　要：分析了目前基于数字版权管理的电子文档保护技术的研究现状,提出了一种可认定非法扩散责任的电子文档保护系统模型,讨论了系统实现中的难点、解决方法与关键技术。通过将用户的特征信息作为数字指纹嵌入到电子文档中,能够在发现电子文档遭到非法扩散时,为用户的责任认定提供必要的技术手段,对合法用户非法传播电子文档的行为具有一定的约束作用。current research situation in the electronic document protection based on digital rights management technology is analyzed, the new model of electronic document protection system that Can be available for identifying the responsibility for illegal Leakage of electronic document is put forward, the implement difficulties, solutions and key technologies in the model is discussed. By imbedding users＇ characteristics information regarded as digital fingerprint into the electronic document, the essential technological means can be offered to identify the users＇ responsibility once the electronic document is leak illegally, so it have certain force of constraint for the users＇ illegal leakage of the classified electronic documents.

关 键 词：责任认定 数字版权管理 电子文档保护 数字指纹
