Security of Transactional Media Systems in the Cloud Using IMF and Other File Formats

With the number of media platforms and the demand for regionalization and localization increasing, technology such as interoperable mastering format from SMPTE opens the door for standardized interchange of versioned content. This paper looks at the security concerns that might need to be addressed and some of the technologies that address those concerns when high-quality versionable masters are stored in the cloud for rendering directly into a customer’s delivery format. The paper considers many issues of security and efficiency including: (1) identity of the parties trading an asset, (2) establishing trust between parties, (3) encrypting the media, (4) authenticating access to the media, (5) ownership of media components, technical metadata, delivery profiles, and transaction metadata, and (6) compromises between security and efficiency.
