Abstract

Digital watermarking techniques have been proposed for the copyright protection of digital images. A digital watermarking technique is a technique for embedding invisible watermarks in a digital image. The watermarks must be designed to be unrecognizable by unauthorized people and to be identified by the legal copyright owner of the image. In this paper, we proposed a new copyright watermarking scheme. Our scheme is based on one-way hash functions, which are widely used in cryptosystems. The main goal of our method is to design a secure watermarking scheme
