Secure Content Delivery via Device Profile Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content streaming systems cannot ensure secure delivery of content when the content provider lacks control over the client application, as certificates are ineffective in such scenarios.
Innovation Solution
A secure content delivery system that verifies device profiles through a database of properties and uses dynamic profile verification requests to authorize devices, preventing unauthorized access and content theft, employing a content system manager and media unit for secure streaming over public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If certificates are used for secure streaming, then content security is improved, but the system requires provider-controlled client applications which limits device compatibility
Solution Approach 1:
The patent introduces a profile verification mechanism as an intermediary between the content provider and the media player. Instead of requiring direct certificate-based authentication between provider and client, the system uses a profile database and verification requests as a mediator. The content system manager stores device profiles and sends verification requests to media players, which respond with profile data. This intermediary layer enables secure authentication without requiring provider-controlled applications, thus resolving the contradiction between content security and device compatibility.
2Reliability
If profile verification is implemented, then unauthorized access prevention is improved, but system complexity increases due to database requirements
Solution Approach 1:
The patent extracts the authentication logic from the media player and places it in the content system manager. The media player becomes a simple respondent that provides profile data, while the content system manager handles the complex profile verification process. This extraction reduces the complexity burden on the device side and centralizes the verification logic in the content delivery system, making the overall system more manageable while maintaining strong unauthorized access prevention.
Data Source
AI summary
A system and method for secure content delivery is provided. The system and method has a content system that verifies a device with a media player based on one or more properties of the device with the media player wherein the content system delivers content to the device with the media player only when the device with the media player is verified.
