A Novel Approach for Implementation of Robust Watermarking for Images

Anup. V. Kalaskar; Prof. Yash Kshirsagar; Shilpa. R. Jadhav

In this paper we introduce approach for implementation of robust watermarking for images. It is to be expected that digital photographs, videos, and sound tracks will gradually replace their analog counterparts in the near future. Digital representation of signals brings many advantages when compared to analog representations, such as lossless recording and copying, convenient distribution over networks, easy editing and modification, and durable, cheaper, easily reachable archival. Unfortunately, these advantages also present serious problems including wide spread copyright violation, illegal copying and distribution, problematic authentication, and easy forging. Piracy of digital photographs is already a common phenomenon on the Internet. Information hiding in digital documents provides a means for overcoming those problems. Depending on what information in which form is hidden in the image, one can distinguish at least two types of data hiding schemes: non-robust, undetectable data hiding, and robust image watermarking. The objective is to implement robust image watermarking by embedding 32 bits of information into a single image in such a way that it is robust to JPEG compression and cropping
