Analysis and Implementation of Digital Watermarking Using Spread Spectrum Method

Abstract

In this research paper, a new approach for digital watermarking using the spread spectrum method is proposed that can address the enduring issues faced with copyrighting digital data. Discrete Wavelet Transform (DWT) technique is applied to overcome the problems concerning authentication and protection of digital media. The aim is to hide the watermark image in the host image without affecting its robustness. After going through the implementation, the invisibility of the watermark image is almost 100%, and the robustness of the host image is around 80%, which is good enough to ensure the protection of contents from different attacks. This watermarking method will ensure the authentication of digital media, and it can be used for limiting usage control, content labeling to protect the ownership, and making an assertion about the owner.
