User Rights Authentication for Network DVR Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network-based DVR systems face high transaction loads due to the need for frequent user rights authentication, particularly during simultaneous recording and playback, which can spike to millions of transactions, leading to inefficiencies and increased network load.
Innovation Solution
A method and system for processing user rights that authenticate user entitlement based on the state of user rights at the time of content storage, allowing playback authorization independently of the time of request, thereby reducing the transaction load by processing entitlements retroactively and minimizing network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user rights authentication is performed at the time of playback, then content protection is ensured, but transaction load spikes to millions of transactions causing network congestion
Solution Approach 1:
The system performs preliminary user rights authentication at the time of content storage (first time) rather than at playback time. The entitlement server authenticates user rights and stores authentication results with the content, so that during playback the system only needs to verify the pre-stored authentication state, dramatically reducing transaction load during peak playback periods while maintaining content protection
Solution Approach 2:
The authentication process is segmented into two phases: (1) initial authentication at storage time where user rights are verified and results are stored with content metadata, and (2) verification at playback time where only the pre-stored authentication state is checked. This segmentation moves the computationally intensive authentication work away from playback高峰期 to distributed storage operations
2Reliability
If entitlement checks are performed at the start of recording or playback, then content authorization is ensured, but network transaction load increases significantly
Solution Approach 1:
The system performs entitlement verification preliminarily at content storage time and stores the authentication state with the content. During playback, the system retrieves and verifies the pre-stored authentication state rather than performing new entitlement checks, significantly reducing network transaction load while ensuring content authorization is maintained
Solution Approach 2:
The authentication state and user rights information are copied and stored with the content metadata at the time of storage. This creates a local copy of the authorization information that can be verified without requiring continuous network communication with the entitlement server, reducing network load while maintaining authorization integrity
