The use of digital media applications , and copyright protection has obtained tremendous importance. Real time camera image digital Watermarking is a technology used for the copyright protection of digital applications. digital encryption and decryption, its history, requirements, and application. Due to piracy of data the need to have some technique to prevent piracy and illegal copying of data arises. This need give rise to a new technique, known as Digital Watermarking. While proposing any algorithm some parameters are needed to keep in mind on which the proposed algorithm must be consistent. These parameters are discussed in following section. Following sections are dedicated to watermarking application and attacks. A lot of work is going on for making watermarking techniques immune towards attack to retain the originality of image in receiving end and assuring successful extraction of encryption image to receiving the decryption image Iin receiving side with low error probabilities so to sort out disputes, if any, over copyrights or ownership of image.
