Image security

Over the past decades, research in security has concentrated on the development of algorithms and protocols for encryption, authentication, and integrity of textual data or data with similar characteristics. despite tremendous advances in security-specifically, the development of asymmetric cryptographic protocols and the inception of strong symmeric ciphers-plenty of security problems still afflict systems. For example, hackers exploiting weaknesses in other systems and the use of inadequate (too short) cipher keys produce frequent news headlines about broken security systems.
