摘要：The present paper provide the conceptual framework on security issue in Watermarking. In the modern era of Information and Communication Technology, each and every user need secure communication. The image watermarking is widely used to provide the security. Watermarking is used to provide such kind of security. In image watermarking, it is the process of engrafting information into a digital signal which may be used to affirm its authenticity or the affirm of its owner. Detailed discuss has been provided on the basis of the three phases. In the first phase of present paper focus has been made on image watermarking and data set will be prepared on which watermarking technique will be executed. Second phase need to locate a specific watermarking technique [LWT WALSH HADMARDSVD] which will provide appropriate results in term of PSNR and processing time. In second phase various attacks will be tested on images so that implemented method must stand against various attacks. Last phase emphasise on reverse process will be executed to extract cover and watermark image. Proposed technique is based on the secure encryption watermark .It is associated with image encryption. The encryption algorithm had been introduced in which watermarking information was based on the size of an image. Proposed techniques provide high level of security. It is clear from the outcomes of the hybrid proposed technique shows that it provides more security than the existing technique.
