Virtual Reality Media Access Control via Segmented Key Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media content distribution technologies lack effective access control mechanisms to protect virtual reality media content from unauthorized access while ensuring quality user experiences.
Innovation Solution
A virtual reality media content access control system that selectively provides access based on access permissions profiles and authorization data, allowing for customized and secure presentation of virtual reality media content to authorized users, using a combination of access keys, device keys, and metadata to manage access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing media content distribution technologies are used, then media content can be distributed to users, but the media content lacks effective protection from unauthorized access and misuse
Solution Approach 1:
The access control system is segmented into multiple independent components: access keys for user identification, device keys for device authentication, metadata for content information, and access permissions profiles for authorization rules. This segmentation allows each component to perform its specific function efficiently while collectively providing comprehensive protection against unauthorized access.
Solution Approach 2:
The patent introduces an intermediary access control system that mediates between the media content distribution system and end users. This intermediary layer validates access keys, device keys, and metadata against access permissions profiles before allowing content access, thereby protecting media content without requiring direct modification of the distribution infrastructure.
2Reliability
If access control mechanisms are implemented to protect virtual reality media content, then unauthorized access is restricted, but the system complexity increases
Solution Approach 1:
Access control parameters including access keys, device keys, and access permissions profiles are established and configured before virtual reality media content is distributed. This preliminary setup ensures that security measures are already in place when content delivery occurs, eliminating the need for complex real-time security decision-making during content streaming.
Solution Approach 2:
The system uses variable parameters such as access keys, device keys, and metadata that can be dynamically changed and updated. These parameters allow flexible configuration of access permissions without requiring structural changes to the underlying system architecture, thereby maintaining simplicity while enhancing security.
3Ease of operation
If existing distribution technologies are used, then media content delivery can occur, but quality user experiences cannot be ensured due to lack of access control
Solution Approach 1:
The access control system incorporates feedback mechanisms where the results of access validation (success or failure) are communicated back to the distribution system and user devices. This feedback loop ensures that only authorized users receive content delivery confirmation, while unauthorized attempts are blocked, thereby maintaining both security effectiveness and user experience quality.

AI summary
An exemplary virtual reality media content access control system (“system”) selectively provides access to virtual reality media content for experiencing by a user of a media player client device (“client device”). In certain examples, the system detects a request from the client device to access an immersive virtual reality world that includes a virtual object assigned an access permissions profile, determines an access key and a device key associated with the request, validates the access key and the device key associated with the request, determines metadata associated with the access key, and selectively provides, based on the access permissions profile for the virtual object and on at least one of the device key associated with the request and the metadata associated with the access key, access to the virtual object for experiencing by the user of the client device as part of the immersive virtual reality world.
