Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in securely and efficiently sharing sensitive user data, such as personal media content, while ensuring accurate proof of location and ownership, particularly in decentralized systems without a trusted central authority.
Innovation Solution
A method and apparatus utilizing a distributed ledger to associate spatiotemporal information with user data, generating a proof of location indication transaction, and enabling secure sharing of user information by verifying user consent and ownership through a decentralized consensus algorithm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized server is used to control access to sensitive user data, then trust and access control are improved, but system complexity and single point of failure risk increase
Solution Approach 1:
The patent extracts the centralized server from the system architecture and replaces it with a distributed ledger network. User data remains on user devices while the ledger stores only access control transactions and proofs, eliminating the single point of failure while maintaining access control reliability.
Solution Approach 2:
The system segments functionality between user devices (storing sensitive data), wireless access network devices (verifying location), and the distributed ledger (recording access transactions). This segmentation distributes trust and eliminates the need for a centralized server while maintaining secure access control.
2Productivity
If user data is shared widely via social media services, then data distribution and accessibility are improved, but privacy security and data misuse risk increase
Solution Approach 1:
The distributed ledger acts as an intermediary between data sharers and data recipients. It verifies user consent, location authenticity, and ownership through cryptographic proofs before enabling data sharing, thus facilitating productivity while protecting against privacy risks.
Solution Approach 2:
The system performs preliminary verification of user consent, location proof, and ownership authentication before allowing any data sharing to occur. This preliminary action ensures that only authorized sharing happens, preventing data misuse while maintaining sharing productivity.
3Measurement precision
If location proof is required for data sharing, then data authenticity and ownership verification are improved, but system complexity and processing overhead increase
Solution Approach 1:
User equipment generates its own location proof using onboard sensors and wireless network information, without requiring complex external verification infrastructure. The proof is then validated by the distributed ledger using standard cryptographic methods, achieving precise location verification with minimal added complexity.
4Reliability
If decentralized system is used without trusted central authority, then system reliability and resistance to single point of failure are improved, but trust establishment and consensus coordination become difficult
Solution Approach 1:
The distributed ledger serves multiple functions simultaneously: it stores location proofs, records user consent, verifies ownership, coordinates data sharing, and establishes trust among participants. This multi-functionality achieves reliable decentralized operation without requiring overly complex specialized mechanisms for each function.
