Device Identification via Intermediary Authentication Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content service providers face challenges in establishing a uniform and secure authentication method across diverse devices, as existing security solutions are inconsistent and not easily verifiable, making it difficult to manage content access and prevent unauthorized sharing.
Innovation Solution
The system allows for device authentication using any security solution, generating identifiers independent of the device type or security solution, enabling devices to request content secured by a different security protocol, and renewing identities and keys for secure communication with a content distribution system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated public key infrastructure (PKI) is used for secure authentication, then security is improved, but compatibility across all devices deteriorates and additional software installation is required
Solution Approach 1:
The patent introduces an intermediary authentication mechanism that mediates between the security requirements and device compatibility. Instead of requiring dedicated PKI infrastructure on each device, the system uses an intermediary authentication server that handles the cryptographic operations, allowing devices to authenticate securely without having PKI software installed locally.
Solution Approach 2:
The patent replaces the mechanical/PKI-based authentication system with a software-based alternative that uses standard communication protocols. Instead of relying on hardware-enforced PKI infrastructure, the system uses software-implemented cryptographic verification that can operate across diverse device platforms without additional hardware or software installation.
2Adaptability or versatility
If third party DRM security solutions are used, then accessibility across device classes is improved, but security verifiability outside the security solution deteriorates
Solution Approach 1:
The patent introduces an intermediary authentication server that acts as a trusted third party to verify security credentials. This intermediary can validate authentication tokens from various DRM systems and provide verifiable confirmation of device authentication status outside the original security solution context, enabling cross-platform verification.
Solution Approach 2:
The patent creates a universal authentication mechanism that can verify security credentials from multiple different DRM systems and security solutions. The authentication server is designed to handle various security protocols and provide a unified verification interface, making security verifiable across different platforms and security implementations.
3Reliability
If device authentication is tied to a specific security solution, then security control is improved, but ability to access content from different security solutions deteriorates
Solution Approach 1:
The patent implements a universal authentication token system that maintains security control while enabling access across different security solutions. The authentication server issues standardized tokens that encode security verification information in a solution-agnostic format, allowing authenticated devices to access content protected by different DRM systems without being locked to a single security solution.
Solution Approach 2:
The patent transforms the authentication mechanism by changing the parameters from solution-specific credentials to standardized authentication tokens. This parameter transformation allows the system to maintain strict security control through verified authentication while enabling cross-solution access through standardized token presentation and verification.
