Hence, it is called fragile watermarking to differentiate this method from regular watermarking that should present some robustness against image alterations. ...
But, by using the BATH dataset comprising 32 000 iris images collected for 1 600 distinct eyes, we verify that the proposed alterations have no impact on iris recognition reliability, although statistically ...
This can be explained by a smaller area that must be searched for the iris when the image is being segmented. ...

This study proposes an embedded block hash searching scheme at the decoder side to achieve motion estimation and recover the lost packets, while maintaining format compliance and cryptographic provable ...
Traditional cryptographic encryption can achieve provable security but is unfortunately sensitive to a single bit error, which will cause an unreliable packet to be dropped to create packet loss. ...
With the search range, the block hash is extracted from each macroblock belonging to Φ ψ , and compared with the extracted hash MH j,k,l by calculating the Hamming distance. ...
