Mediated Reality Server Secure Content Publishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing devices face challenges in securely publishing and consuming mediated reality (MR) content, particularly with DRM-protected high-value content, due to difficulties in managing licensing rules and unauthorized access in non-trusted environments, and in combining content from multiple creators while ensuring content restrictions are honored.
Innovation Solution
A system comprising a mediated reality server that performs attestation procedures, securely distributes session and back-channel encryption keys, aggregates and licenses MR content, and enforces DRM licensing requirements, ensuring secure content publishing and consumption while allowing for rich MR experiences and follower feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM-protected content is used in MR experiences, then content security and licensing control are improved, but content manipulation and processing become difficult in non-trusted environments
Solution Approach 1:
The patent introduces a trusted computing environment (TCE) as an intermediary between DRM-protected content and MR processing operations. The TCE acts as a secure mediator that enables content manipulation while maintaining DRM protection, allowing licensed operations to proceed within the trusted boundary without exposing the underlying protected content to unauthorized access or manipulation outside the TCE.
Solution Approach 2:
The system segments the computing environment into trusted and non-trusted zones. The trusted computing environment is isolated from the general non-trusted system, creating distinct operational boundaries. This segmentation allows DRM-protected content to reside securely in the TCE while enabling controlled interactions with external MR processing tools through defined interfaces and APIs.
2Adaptability or versatility
If content from multiple creators is aggregated, then MR experience richness is improved, but licensing rule management and restriction enforcement become complex
Solution Approach 1:
The patent implements a universal licensing management system within the trusted computing environment that can handle multiple licensing schemes simultaneously. The TCE provides a multi-functional platform that processes different creator licensing rules through a unified interface, automatically managing rights, restrictions, and permissions for aggregated content from multiple sources without requiring separate management systems for each creator.
Solution Approach 2:
The system incorporates feedback mechanisms that track and report licensing compliance status across aggregated content. The trusted computing environment monitors usage patterns and provides feedback on restriction enforcement, enabling dynamic adjustment of licensing rules and ensuring that content from multiple creators adheres to their respective terms while being combined in the MR experience.
Data Source
AI summary
Technologies for secure mediated reality content publishing includes one or more mediated reality servers, multiple mediated reality listeners, and multiple mediated reality creators. The mediated reality server performs an attestation procedure with each listener based on a pre-provisioned attestation credential of that listener and provisions a session encryption key to each validated listener. The attestation procedure may validate a trusted execution environment of each listener. The mediated reality server generates aggregated mediated reality content based on protected mediated reality content received from the creators and generates an associated license that defines one or more content usage restrictions of the aggregated mediated reality content. The server sends the aggregated mediated reality content to the listeners, protected by the corresponding session encryption key. The server may provision each of the listeners with a back-channel encryption key to protect feedback data generated by sensors of the listeners. Other embodiments are described and claimed.
