Remote Authentication for Audio-Visual Products via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional encryption and authentication methods for audio-visual products fail to provide reliable copyright protection as they typically conduct authentication on the player side, making them vulnerable to illegal access.
Innovation Solution
The authentication data and process are separated by transmitting authentication data from a player to a mobile communication device, which then forwards it to an authentication server for processing, ensuring that the authentication occurs remotely and not on the player side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication data and authentication process are both conducted on the player side, then the authentication process is simple and fast, but the system is vulnerable to illegal access and copyright protection is unreliable
Solution Approach 1:
The authentication system is segmented into multiple independent components: authentication data storage (separate from the player), authentication process execution (on authentication server), and result verification (at player). This segmentation prevents unauthorized access because no single component contains both the keys and the authentication logic, resolving the contradiction between reliability and complexity.
Solution Approach 2:
An authentication server acts as an intermediary between the player and the authentication data. The server receives authentication requests, processes them using stored authentication data, and returns results. This intermediary architecture enhances copyright protection reliability by centralizing secure authentication operations while maintaining system manageability through standardized communication protocols.
2Reliability
If authentication data is separated from authentication process and stored remotely, then copyright protection is more reliable, but the authentication system becomes more complex
Solution Approach 1:
Authentication data is extracted from the player and stored remotely on an authentication server. The player only retains authentication logic and result verification capabilities, while the sensitive authentication data resides in a secure remote location. This extraction improves authentication security by removing the security vulnerability of having both data and processing on the same device, while the standardized interface minimizes the perceived complexity.
Solution Approach 2:
The authentication server serves as an intermediary that manages authentication data securely and processes authentication requests. This mediator architecture separates concerns: the player handles user interaction and basic processing, while the server handles secure data storage and authentication logic, making the overall system more manageable despite the distributed architecture.
3Reliability
If authentication is conducted remotely over wireless network, then illegal duplication is prevented, but authentication time and network dependency increase
Solution Approach 1:
Authentication data is pre-loaded and securely stored on the authentication server before any playback occurs. When a player requests authentication, the server already has the necessary credentials ready, enabling rapid verification without requiring real-time data retrieval or complex computations during the authentication moment, thus reducing authentication time while maintaining strong anti-duplication protection.
