Digital Watermarking Using MATLAB

Digital Watermarking Using MATLAB

Embedding a hidden stream of bits in a file is called Digital Watermarking. The file could be an image, audio, video or text. Nowadays, digital watermarking has many applications such as broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control, device control, and file reconstruction (Cox et. al., 2008). In literature, the host f...

DWT Based Blind Digital Video Watermarking Scheme for Video Authentication

Digital video is one of the popular multimedia data exchanged in the internet. Due to their perfectly replicable nature many illegal copies of the original video can be made. Methods are needed to protect copyrights of the owner and prevent illegal copying. A video can also undergo several intentional attacks like frame dropping, averaging, cropping and median filtering and unintentional attack...

Matlab Simulink Based Digital Protection of Transformer

Power transformer is one of the most important equipment in a power transmission and distribution system. This paper presents a technology to simulate differential relay in Matlab Simulink based environment for determining its behavior during various operating conditions. The results show that this simulation method can work properly and this will allow rapid modeling and testing of new algorit...

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...
