Enhanced Watermarking Technique using Computational Wavelet and Cosine Transformation

Harmandeep Kaur, Simarjeet Kaur

Abstract: Over the use of Internet, digital watermarking provides the protection for multimedia data. In the contemporary days, misuse of multimedia data is done at a huge level and encryption of the sensitive data flowing through the network or Internet is one of the most important factors for the copyright issues. So, in order to save the information from being stolen or misused, digital watermarking technique is proving to be a great invention in the field of information technology and multimedia. It comprises of general process of lodging the data in the original content. Where data can be in any form, whether audio, video, image or text. The text can be concealed in the image, audio or video as a watermark. Moreover, the fraud use of important data can be avoided using this type of encryption. In this research paper, an idea of watermark is proposed and implemented. To sum up, the PSNR, MSE, NC of the watermarked image would be calculated to check the quality of image and would be compared with others.
