摘要
内容认证技术对多媒体在传播过程中感知内容的真实性、完整性和原始性进行鉴定。国内外学者已经提出了很多认证算法,但基础理论的缺乏制约着研究工作的进一步开展。本文从认证技术的内在规律出发,定义了内容认证系统基本概念和表达符号,指出了认证系统的性能评价体系和方法。这些方法可以简单明确的对认证系统进行表达与分析,可以作为多媒体内容认证进一步研究的基础。
The Content Authentication Technology verifying the reality, the completeness and the originality of multimedia in the process of communication. Many algorithms have been proposed, but the lack of basic theory restricts the development of future research works. We first defined the basic concepts and express symbol of Content Authentication System. Then the performance analysis methods of authentication system are introduced. These methods can clearly express and analyze an authentication system, and can be a base of content authentication technology research.
