Abstract

The security of the multimedia file is one of the central concerns in this era of online trade and communication. This paper proposes an algorithm for the robustness of authenticity of digital image against various attacks through embedding and extracting watermarking into image. Using DWT-SVD technique, the RGB colors are separated from both cover and watermark image. For watermarking process, a threshold values from R planes of the watermark image is integrated into R channel of the cover image. The experimental result shows that this method has better robustness against known attacks.
