Spatial Domain Robust Watermarking Scheme for Color Image
Designing an efficient watermarking technique for digital media is still a challenge. Here we presented a robust watermarking method in spatial domain of the color image. We divided the image into eight parts and embedded the binary form of the copyright information after encrypting each bit with a secret key, inside the blue component of the color image. We used a random sequence for selecting the pixel in which we want to insert the information. We stored the information in the blue component of the pixel. We put the recovery record by changing the corresponding green component of the pixel, comparing the changed blue component and the red component of the pixel.. The extraction of the copyright information is based on comparing red and green component with the blue component of the pixel from any available block or part of the any eight block of the image. Testing is done by Stirmark benchmark 4.0. The test result shows that the proposed method is very secure and robust against various attacks.
