Abstract
Image authentication has achieved a sharp attention now a day due to broad availability of internet services. Maldistribution and illegal copying of image volatiles the authenticity of image-ownership. In this regard the digital watermarking-based image authentication system is studied. A color image authentication system is proposed. This system converts a color image into a grayscale image, and divides the grayscale image into 8*8 small pieces. Each small piece is made into DCT transform and extracted low frequencies to form the watermark. Then, the original image uses LSB algorithm and hash algorithm in watermark image to form authentication code. The system makes the authentication code as watermark information to embed watermark. The system is made in experiment. The result shows the system has good imperceptibility.
