Implementation of watermarking technique using matlab

Abstract

Everyone uses the internet for their personal or professional use. Due to this it is important to protect user data from unauthorized access. When we talk about copyright protection means an unauthorized person claims that copied data was created by him. What do we do at that time? How can we prove that we are the right owner of data? To overcome this problem Digital watermarking mechanism is used to protect data from illegal copies or illegal distribution. It is an art of hiding information into digital data in a way , unauthorized people can’t access or copy that data for misuse. Data which is inserted into digital media is called watermark. It is information (any label, citations, author name, id) about data. The proposed paper is an analysis of new enhancements in digital image watermarking techniques in both spatial domain and transform domain.
