Because multimedia files can be shared with increasing ease and efficiency, the need to ensure their secure transmission and consumption has become acute, particularly in light of multimedia-specific exploits. This article explores a variety of strategies and technologies that address the requirements and implementation elements of secure multimedia communications. To maintain acceptable performance, a security strategy must be aware of multimedia-specific needs and not severely detriment metrics such as jitter and frame rate. The wrong security techniques can burden the data with excessive encoding that reduces its perceptual quality and doesn't achieve the intended security objectives.
