DESIGN AND DEVELOPMENT OF USER SELECTION SYSTEM FOR WATERMARKING TECHNIQUE AS VISIBLE AND INVISIBLE

Sandeep Singh, Rakesh singh

Watermarking is the process that embeds data called a watermark, a tag, or a label into a multimedia object, such as images, video, or text, for their copyright protection. According to human perception, the digital watermarks can either be visible or invisible. A visible watermark is a secondary translucent image overlaid into the primary image and appears visible to a viewer on a careful inspection. The invisible watermark is embedded in such a way that the modifications made to the pixel value are perceptually not noticed, and it can be recovered only with an appropriate decoding mechanism. This paper presents new visible and invisible watermarking using discrete wavelet transform (DWT). The proposed architecture is designed to compare the results of visible and invisible watermark on the basis of BER, MSE and PSNR.
