A secure invisible watermarking using rijndael algorithm and wavelet transform

Abstract EN

Digital watermarking hides secret or personal information in host digital data to demonstrate and protect the copyrights of digital products, to authenticate the contents of digital data, or to convey side information such as access control or annotations.

There are several fundamental requirements for watermarking such as : Perceptual invisibility.

For robustness, a watermark should be resistant to a variety of manipulations, either unintentional or malicious.

The detection should be accurate and especially the mean square error rate should be very small.

To help protect the copyright and data security, Rijndael algorithm will be used using many mathematical operations like (byte substitution, shift row, mix column and add round key).

The wavelet transform or wavelet analysis is probably the most recent solution to watermarking Rijndael code.

Meaning by factoring technique for invisible watermarking Rijndael code is calculated and inputted in random locations.

At the end, a detection process based on back propagation neural network will be used to detect watermarking string
