HYBRID NONBLIND WATERMARKING BASED ON DWT FHT AND SVD

Electronics and Communication Engineering

Watermarking the image files is an extremely proficient method used to the field of communication technology. When any information required to transmitting from one place to another security is vital. This security is provided by hiding data into the images, audio and video. It details about the different watermarking techniques gives the clear concept of the watermarking scheme. It proposed a digital watermarking technique which is based on hybrid watermarking. Using hybrid watermarking technique, watermark the image with another image it gives the watermarked image. Evaluate the performance of PSNR for watermarked image. Evaluating the three parameters of PSNR, MSE and SSIM for various types of attacks and the proposed watermarking technique is imperceptible. Explore the robustness of the proposed watermarking technique by evaluating the parameters of PSNR, MSE and SSIM.
