STUDY ON IMAGE BROADCAST USING WATERMARK AND SECURITY TECHNIQUES
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 4
Abstract
Image broadcast is existing in this paper by experimental outcomes. In this method, an unauthorized person is easily determine through piracy of an image. Watermark is appended into image at the time of sending an image. Embedding the information into a digital signal is called as watermark and it is used to verify authenticity or identity of its owner. The embedded message contains some encryption of data. Cryptography and Digital Signatures are mainly used to provide security. Whatever the message will be added to image as watermark is also be extracted from watermark image to overcome different types of attacks such as image-processing operations. Digital signature and encryption must be applied at message creation time to avoid tampering. Probability and strength have been satisfied by encryption and watermark.
