Information-Processing Device Domain Authentication for Copyright Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in effectively protecting copyrighted digital content from unauthorized access and distribution over IP networks, where VPN technology allows remote connections, potentially bypassing geographical restrictions.
Innovation Solution
An information-processing device with interfaces for unique identification management and authentication, using AKE processing and encryption-decryption to control content transmission based on stored unique IDs, ensuring that content is only transmitted within authorized domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VPN technology is used to connect remote home networks over IP, then network connectivity and content accessibility are improved, but copyright protection is compromised as content can be accessed beyond authorized geographical boundaries
Solution Approach 1:
The patent introduces a domain management server as an intermediary between content providers and users. This server acts as a mediator that verifies user domain information and controls content distribution permissions, preventing unauthorized access while maintaining legitimate network connectivity. The server mediates between the need for remote access and copyright protection by validating domain boundaries before allowing content transmission.
Solution Approach 2:
The system performs preliminary verification of user domain information before allowing content access. The domain management server checks whether the user's domain ID matches the authorized domain for the content before permitting transmission. This preliminary action prevents copyright infringement by validating authorization credentials in advance, rather than attempting to control access after content has been distributed.
2Object-affected harmful factors
If content transmission is restricted to specific geographical areas, then copyright protection is improved, but network utility and content accessibility are reduced
Solution Approach 1:
The patent implements dynamic content distribution control based on user domain verification. Rather than static geographical restrictions, the system dynamically determines whether to permit or block content transmission based on real-time verification of the user's domain ID against the authorized domain for the content. This dynamic approach maintains copyright protection while allowing flexible content accessibility within authorized domains.
Solution Approach 2:
The system changes the control parameter from physical geographical location to logical domain identification. By using domain IDs and comparing them against authorized domains, the system maintains copyright protection through logical boundaries rather than physical restrictions. This parameter change enables content to be accessible anywhere within the authorized domain while blocking access from unauthorized domains, regardless of physical location.
3Object-affected harmful factors
If unique identification verification is implemented for content transmission, then copyright protection is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent extracts the complex authentication and domain verification functions from individual content-transmitting devices and consolidates them into a centralized domain management server. Individual devices only need to transmit their domain ID, while the centralized server handles the complex verification logic, domain boundary checks, and permission decisions. This extraction reduces device complexity while maintaining comprehensive copyright protection.
Solution Approach 2:
The system uses domain IDs as simplified copies or representations of complex user identity and authorization information. Instead of verifying complete user profiles, cryptographic credentials, or detailed device identities, the system uses concise domain ID strings that capture the essential authorization information. This copying approach maintains security while reducing processing overhead and simplifying the verification process.

AI summary
An information-processing device includes a first interface configured to transmit content to a first communication unit through a network, a second interface configured to receive a first unique identification allocated to the first communication unit from a second communication unit and transmit a second unique identification allocated to the information-processing device to the second communication unit, an identification list configured to store at least one unique identification through the second interface and an identification judgment unit configured to determine whether the first unique identification received through the first interface is stored in the identification list, wherein when the identification judgment unit determines that the unique identification of the first communication unit is stored in the identification list, the first interface allows the content to be transmitted to the first communication unit.
