Digital watermarking scheme is used to protect copyrights of owners. We proposed blind watermarking scheme based on DCT (Discrete Cosine Transform) algorithm. The proposed method provides hiding a watermark in Gray Scale Image. Digital color image is transformed into Gray Scale Image then the DCT algorithm is used for watermarking process. Block based DCT algorithm used for embedding watermark. For embedding watermark, all bits of the watermark image are embedded in various DCT blocks. To extract watermark same process will be done in inverse manner. In such watermarking scheme, it requires original image to retrieve embedded image where in blind watermarking process it doesn't require cover image to retrieve embedded image.

Abstract


Digital watermarking scheme is used to protect copyrights of owners. We proposed blind watermarking scheme based on DCT (Discrete Cosine Transform) algorithm. The proposed method provides hiding a watermark in Gray Scale Image. Digital color image is transformed into Gray Scale Image then the DCT algorithm is used for watermarking process. Block based DCT algorithm used for embedding watermark. For embedding watermark, all bits of the watermark image are embedded in various DCT blocks. To extract watermark same process will be done in inverse manner. In such watermarking scheme, it requires original image to retrieve embedded image where in blind watermarking process it doesn't require cover image to retrieve embedded image.
