Analysis of Secure Watermarking Based on DWT-SVD Technique for Piracy

In this paper, application of the secure watermarking scheme based on DWT-SVD domain is examined for piracy. This technique cryptography based on invisible and compressed (using DWT-SVD) watermark image embedded into host image without make an impression the imperceptibility and increase the security of watermark, this technique provides a robust solution for watermarked image. A comparative study of various watermarks attacks is also examined. Space complexity has also been taken into consideration, which makes this technique lesser space complex in comparison to other techniques. The performances of the secure watermarking technique are compared on the basis of entropy and PSNR values.
