摘要

在许多多媒体应用中，除了潜在的篡改攻击外，还需要对受到噪音、压缩等良性降解的信号源进行验证。认证可以通过在原始信号中嵌入适当选择的标记来实现。我们对这一问题进行了信息论表述，并确定和解释了相关的基本性能限制。

On authentication with distortion constraints

In many multimedia applications, there is a need to authenticate sources subjected to benign degradations such as noise, compression, etc., in addition to potential tampering attacks. Authentication can be enabled through the embedding of suitably chosen markings in the original signal. We develop one information-theoretic formulation of this problem, and identify and interpret the associated fundamental performance limits.
