The Comparative Study of DCT and DWT in Blind Detection Based Digital Watermarking
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 5
Abstract
Digital Watermarking is one of the data hiding technique, has been popular in today for providing copyright protection. Fundamentally, to implement a digital watermarking, there are two approaches, pixel modification based and frequency domain based. In frequency domain based watermarking techniques, DCT and DWT are commonly used and popular today. The purpose of this paper is to compare and represent watermarking performance with the same technique, the two techniques; DCT and DWT are presented with new approach. At first, the new approach watermarking technique is discussed and proposed. In the technique, on-line handwritten signature is acquired from G-Pen F350 tablet, which is used as watermark. Watermark is embedded in mid-band DCT domain. On the other hand, LH band of DWT is used as embedded media.Finally with the help of experimental results, several performance analyses over the robustness of watermark against various attacks of each technique are compared to determine which technique is better
