Research on Fragile Watermarking based on Image Authentication

摘要：

　　To keep algorithm”s high robustness and accuracy, a semi-fragile digital watermarking algorithm based on slant transform and chaos sequence was proposed.As the Slant transform has a high energy and have a fast calculation.Chaos sequence also has a good privacy.Experiment results show that the algorithm tolerates the accidental tampering, such as the gauss noise ,JPEG compression, etc.The tampered areas can be detected effectively and located accurately.
