Real Time Analysis of Digital Watermarking Techniques

Digital watermarking includes a number of techniques that are used to imperceptibly convey information by embedding it into the cover data. There has always been a problem in establishing the identity of the owner of an object. In case of a dispute, identity was established by either printing the name or logo on the objects. But in the modern era where things have been patented or the rights are reserved (copyrighted), more modern techniques to establish the identity and leave it untampered have come into picture. Unlike printed watermarks, digital watermarking is a technique where bits of information are embedded in such a way that they are completely invisible. The problem with the traditional way of printing logos or names is that they may be easily tampered or duplicated. In digital watermarking, the actual bits are scattered in the image in such a way that they cannot be identified and show resilience against attempts to remove the hidden data.
