Performance Evaluation of LSB Technique for Digital Watermarking
نویسندگان
چکیده
Watermarking of digital content is an imperative and interactive method for identification and protection of digital data. It allows veritable watermarks to be hidden in digital data for example image, audio, and video. Procedure of embedding and extracting of watermark from original image and watermarked image is complex. These include randomization of the watermark and selection of locations to embed and extract it from the specific locations. Proposed work gives a robust digital watermarking algorithm that follows Least Significant Bit Technique. Embedding of watermark is done at the least significant bit of each pixel value of the cover image. Watermarked image is used to extract the watermark without any help of the original image. Parameters used to evaluate the performance watermarking technique are Peak Signal to Noise Ratio, Mean Square Error and Normalized Cross Correlation for Gaussian noise, Poisson noise, Salt and Pepper noise and Speckle noise.
