DIGITAL WATERMARKING SCHEMES FOR AUTHORIZATION AGAINST COPYING OR PIRACY OF COLOR IMAGES

A number of Techniques have been proposed of watermarking, However our purposed technique is more robust than LSB Technique thus provide better results in case of Copyright

The entropy of the watermarked image and correlation coefficient of extracted watermark image is very close to ideal values, proving the correctness of proposed

Internet digital information protection is achieved through blind watermarking because with watermarked information, message can be detected successfully without original data..

Removal attacks: Removal attacks are attacks that attempt to analyze the watermarked data, estimate the Watermark or the host data, separate the watermarked

In this paper we propose a DWT based dual watermarking technique wherein both blind and non-blind algorithms are used for the copyright protection of the

• Apply inverse Legendre transform (ILT) on each pair of adjusted components to re-generate the pixel components pair in spatial domain. • During inverse transform, if the second

We evaluated the performance of the combined DWT-DCT image watermarking algorithms using a 512 × 512 'Lena' as the original cover host image, and a 256 × 256

Conclusion/Recommendations: Digital watermarking does not alter medical diagnosis when assessed by clinical radiologists.. The quality of the watermarked images was
