DCT-Based--Watermarking-Scheme
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.
