a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery

data and two bit Authentication data of the image block into the least

significant bits (LSB) of its corresponding mapping block.The integrity

of a test block is decided by comparing 2×2 non overlapping block

of the test block with its corresponding mapping block. Experimental

results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well

as in tamper recovery of the image.
