摘要:Availability of digital data such as images, audio and video has increased by the rapid expansion of internet. Public can easily access and share files on internet. With this availability, the technology also needs to enhance to protect data from unauthorized user. To protect infringement of the intellectual property digital watermarking becomes very important. Digital Watermarking is the process of embedding a secret information into a digital data. A methodology for comparing robustness of watermarking techniques is proposed. The techniques are used into a standard form to make comparison possible. In this paper, I will implement three different digital watermarking techniques each from Spatial Domain (LSB) and Transform Domain (DCT and DWT) evaluate their performance using various parameters such as PSNR, MSE, similarity ratio(SR), correlation(CORR) and BCR against robustness for attacks
