COMPARATIVE ANALYSIS OF WATERMARKING IN DIGITAL IMAGES USING DCT,DWT &LSB
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 2
Abstract
Due to large use of internet and high speed development in technology,it is very difficult to transmit information safely from one place to other.For safe and secured transmission of information digital watermarking is used.Watermarking of digital images is a technique of hiding a data, also it gives security of data or identifying information in the digital data. The digital watermarking process embeds a signal into the media without significantly degrading its visual quality. In this paper there is a comparison of three methods i.e. DCT, DWT & LSB based algorithm for watermarking in digital images.
