Implementation of Secured Information Model for Color Image Authentication and Copyright Protection Rapid growth in multimedia and internet has made the requirement of authentication most critical issue in recent times. Copyright protection requires the detection of illegal copies of original images or text documents or video. Similarly we need some scheme with the help of which we can differentiate between the original and fake images that can be further used in court as evidence. Recently we have some methods available that can be used in cases that we discussed so far, steganography, cryptography and watermarking. It is an active research area to develop effective watermarking scheme for different applications. This dissertation work is focusing on implementation of secured information model for authentication and copyright protection.
