A Digital Watermarking Algorithm for Binary Image Authentication

摘要：

An image authentication watermarking technique is proposed. The image block is firstly scrambled by two chaotic sequences. The watermarked image can be got by altering the “flippable pixels according to Pixel Spread Deviation (PSD). Experimental results show the imperceptibility of the watermarking process, the proposed algorithm can successfully localize the content modifications. Further, it can protect the homogeneous region which is the urgent issue in the binary image authentication.
