چکیده مقاله:

Due to high speed computer networks, the use of digitally formatted data has increased many folds.The digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. Digital Watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .Digital watermarking is a well-known technique used for copy rights protection ofmultimedia data. A number of watermarking techniques have been proposed in literature. DigitalWatermarking is the process that embeds data called a watermark into a multimedia object such thatwatermark can be detected or extracted later to make an assertion about the object. A variety oftechniques in different domains have been suggested by different authors to achieve above mentionedconflicting requirements. All the watermarking techniques are different from each other and are usedfor differing applications.

A Robust Digital Image Watermarking Scheme Based on DWT

In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
