A Multiple Redundant Digital Watermarking Technology Basedon Singular Value Decomposition
Eng Z · 2006
This paper proposes a digital watermarking technology,It encrypts the watermarking information with the bit transposition al- gorithm, and carry on singular value decomposition to the original image,and embeds multiple redundant watermarking information . Experiments have proved that the technology proposed in this paper has preferable security and great robustness.It can withstand many kinds of attacks of rotating,cropping etc.
