Abstract:
Authenticating transaction of the digital media becomes an active research field now a day. That is emerging due to the illegal use of data resources and hacking by unauthorized users. In this article, we implemented new algorithms for embedding and extracting watermark. Our algorithm works on spatial domain of digital images where it can embed invisible watermark. A secret key is used to embed and extract watermark. The watermark, according to the secret key, locates in a random manor vertically or horizontally across the base-
