Enabling secure distribution of digital media to SD-cards

摘要

As the marketplace for digital media increases we witness the rise of new media distribution models where timely delivery, convenience, privacy and personalization are essential features of competitive offerings. Consumers are looking for innovative ways to access content in a service-oriented manner that suits their mobile life style. This paper describes a prototype standard-based system that allows the secure and fast download of content to SD-Card-enabled consumer devices. Content is protected by Content Protection for Recordable Media (CPRM) technology; specifically we use CPRM SD-Video. Our prototype shows Digital Media Terminals (DMT, also denoted kiosks) that enable innovative rental and purchase models. Our solution combines IBM's plug-in web services, Panasonic's leading-edge devices and Porto Media's high-speed data transfer to Secure Digital Memory Flash Cards (SD-Cards).
