ContentGuard, spun out of Xerox PARC, specializes in content privacy and protection technologies. The company serves a diverse range of clients, including major technology firms such as LG, Microsoft, Nokia, Panasonic, Sharp, Sony, Toshiba, Casio, Hitachi, Time Warner, and Xerox. Operating in the digital rights management (DRM) market, ContentGuard develops and licenses technologies that safeguard digital content through advanced encryption and mobile number verification. Their solutions prevent unauthorized forwarding and ensure that shared content does not remain on devices indefinitely, thanks to features like countdown timers ranging from 1 minute to 30 days. The business model primarily revolves around licensing agreements, which generate revenue by allowing other companies to integrate ContentGuard's patented technologies into their own products and services.
