Title:
セキュア・メディア・パスのシステム
Document Type and Number:
Japanese Patent JP5390000
Kind Code:
B2
Abstract:
Methods, systems and architectures for processing renderable digital content are described. The various embodiments can protect against unauthorized access or duplication of unprotected content (i.e. decrypted content) once the content has reached a rendering device such as a user's computer. A flexible framework includes an architecture that allows for general media sources to provide virtually any type of multimedia content to any suitably configured rendering device. Content can be protected and rendered locally and/or across networks such as the Internet. The inventive architecture can allow third parties to write components and for the components to be securely and flexibly incorporated into a processing chain. The components can be verified by one or more authenticators that are created and then used to walk the chain of components to verify that the components are trusted. The various embodiments can thus provide a standard platform that can that can be leveraged to protect content across a wide variety of rendering environments, content types, and DRM techniques.
