Image Security
Abstract
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 symmetric 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. Despite the news headlines, such problems have been well explored and even solved in principle, therefore they aren't the primary focus of this special theme issue. Rather the articles here cover the unsolved problems in image security, which relate fairly closely to computer graphics. The unsolved challenges arise from the increased availability and distribution of multimedia content over Internet services such as the World Wide Web and their implications for intellectual property protection and copyright issues.
