Abstract-In the process of transmission, the various factors can effect easily the multimedia information. The receiver can't distinguish whether the received multimedia data has been tampered. The fragile watermarking can authenticate the authenticity and integrality of the multimedia data. The paper analyzes the fragile watermarking based on local binary pattern. Experimental results demonstrate that, in a copy-move and splicing forgery, the existing algorithms can't determine whether a digital image is original or doctored.

Abstract. In order to authenticate the authenticity and integrity of watermark, a fragile watermarking algorithm is proposed for the content authentication of digital media products. First, the watermark is embedded into the least significant bit (LSB) of the pixel of the host image, and then the hash value is generated by the Hash function form the watermark information and is saved the text, Then the watermark hash value is embedded into the image of the carrier. On the authentication side, After extracting the watermark information and the Watermark Digest information, the extracted watermark information is generated by the hash function to generate a new set of watermark summary information, and compared with the extracted watermark information. The experimental results show that the fragile watermarking algorithm can achieve good authentication capability.
