Role of Digital Watermark in e-governance and e-commerce

Watermarking techniques, for four media data - video, image, audio, and text are interpreted as DWvideo, DWimage, DWaudio and DWtext respectively in DWM techniques respectively.. In this paper, we focus on important role of digital watermark in electronic governance and electronic commerce applications. Results show that watermarks for video and audio data have to be invisible and robust, and watermarks for text data has to be invisible and fragile, while watermark for image has to be either visible and fragile, or invisible and robust for electronic governance and electronic commerce applications. The watermark is used to protect intellectual property in electronic governance and electronic commerce applications. This facilitates electronic governance and electronic commerce application developers to select adequate digital watermarking techniques for their development.
