Abstract

In the present work, the multiple watermarking techniques have been executed to present information security. DWT - SVD based multiple watermarking for color images are proposed and has been implemented in cloud computing. The multiple watermarking is used to share the copyright of multiple users improves the robustness and high security. In the proposed work, multiple watermarks are embedded into the cover image. Image quality is computed using Normalized Correlation (NC) and Peak Signal to Noise Ratio (PSNR) for color images. The proposed scheme provides a secure and well imperceptibility to different image processing attacks.
