This paper introduces the PCA’s audio perception hash algorithm of the media perception and significance of the research topic. The related concepts are used in the project to develop tools and also focus on using Mat lab to achieve the technical goal of the project. Theory analysis,design rules and algorithm construction of perceptual hash in content authentication and copy detection are studied. An authentication model based on perceptual hash is propose, then the authentication veracity is described and the difference of authentication veracity of perceptual hash from different features is analyzed.The advantage of perceptual hash construction based on multiple features and multi-resolution is demonstrated according to which a design rule of perceptual hash based on multiple features is proposed.The Authentication model can help to analyze and design perceptual hash schemes effectively by analysis. The effectiveness of the proposed algorithm is demonstrated by the experimental results.
