A Watermarking Approach to Enhance the Protection of Watermarks

Chetika Sharma; Ashish Oberoi; Mamta Oberoi

Digital watermarking is one among the planned solutions for copyright protection of multimedia information. Digital Watermarking describes strategies and technologies that hide data. The embedding takes place by manipulating the content of the digital data (images audio and video), which implies that information is not embedded in the frame around the data. In this research, Fast Fourier Transform is used for image watermarking, that can embed more number of watermark bits within the gray scale cover image and increase the protection of watermarks.
