Digital Image Protection Using Reversible Watermarking And Private Symmetric Key Encryption Technique

Abstract

igital watermarking is a technique which has been recommended as a way to achieve digital protection. The aim of digital watermarking is to embed the data into the image without affecting the visual quality. The related work defines a robust block-based watermarking system on the singular value decomposition (SVD) and human visual system in the discrete wavelet transform (DWT) domain. The proposed method is considered to be a block-based scheme that utilizes the entropy and edge entropy as HVS characteristics for the selection of significant blocks to embed the watermark, which is a binary watermark logo. The proposal work includes reversible watermarking techniques and private symmetric key encryption techniques are processed to maintain high imperceptibility and high robustness and also avoid the distortion caused by the geometric attacks. The experimental evaluation is also obtained for the proposedwork.
