摘要：A new spatial domain probability based watermarking scheme for color Images is
proposed. The blue channel of the color image has been used for watermark embedding. Host image
is divided into 8x8 blocks and each bit of the binary encoded watermark is embedded in each such
block. For each inserted bit, intensity of all the pixels in the block is modified according to the
embedding algorithm. Non-blind probability based watermark extraction is performed with the help
of original host image. The method has been proved to be robust to various image processing
operations such as filtering, lossy image compression, and various geometrical attack such as
rotation, scaling, cropping.
