New Semi-fragile Authentication Watermarking

In this paper we propose a semi-fragile watermarking scheme, which can be used for image authentication. Let the original image be performed by the l-level discrete wavelet transformation. Then the approximate wavelet coefficient matrix of the original image and the real-value chaotic sequences are used to generate the content-based and secure watermark. The watermark is embedded into original image by using the technique of HVS. The tamper detection can identify the tampered region of the received watermarked image which may be undergone tamper attacked. Experimental results are excellent.
