Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems are limited in proving identity, location, and asset custody in a distributed manner while ensuring privacy and security, as they lack robust security mechanisms, are prone to tampering, and inefficient in storing and sharing data across entities.
Innovation Solution
The use of location beacon devices and blockchain technology to transmit secured representations of blockchain addresses, combined with interactive proving protocols, enables secure proof of presence and custody by creating distributed attestations on a blockchain network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized authorities control identity and data, then verification and access control are simplified, but security and privacy are compromised due to central points of failure and misuse
Solution Approach 1:
The system segments identity verification into distributed components: blockchain stores verification records immutably, location beacons provide decentralized location proof, and users maintain control of their own data through cryptographic keys. This eliminates the single central authority while maintaining verification reliability through distributed consensus and cryptographic proof.
Solution Approach 2:
The patent introduces cryptographic proofs and blockchain attestations as intermediaries between users and verifiers. These intermediaries enable verification without exposing raw personal data, acting as a mediator that preserves privacy while establishing trust through mathematical proof rather than centralized authority.
2Ease of manufacture
If traditional data storage and sharing methods are used, then system implementation is simpler, but data integrity and security are compromised due to tampering risks
Solution Approach 1:
The system performs preliminary cryptographic hashing of location and identity data before storage or transmission. This preliminary action creates tamper-evident records that are computationally infeasible to alter, ensuring data integrity is built into the system architecture rather than added as a later security layer.
Solution Approach 2:
The patent replaces traditional mechanical/trust-based security systems with cryptographic and blockchain-based verification. Instead of relying on physical security measures or trusted intermediaries, the system uses mathematical cryptography and distributed ledger technology to guarantee data integrity automatically.
3Reliability
If repeated attestations are required for verification, then security is enhanced through multiple checks, but process efficiency deteriorates due to redundant verification steps
Solution Approach 1:
The system performs verification准备工作 in advance by pre-registering location beacons, pre-generating cryptographic key pairs, and pre-storing verification rules on the blockchain. This preliminary setup enables rapid verification execution without repeated complex computational steps, maintaining security while improving efficiency.
Solution Approach 2:
The patent uses cryptographic copying where a single verification attestation on the blockchain can be referenced multiple times by different verifiers without requiring repeated full verification processes. The immutable blockchain record serves as a reusable copy that proves verification once and for all, eliminating redundant checks.
4Measurement precision
If detailed personal data is stored for verification, then verification accuracy is improved, but privacy protection deteriorates due to data exposure risks
Solution Approach 1:
The system extracts only the essential verification elements from personal data and stores them on the blockchain in hashed or encrypted form. Instead of storing complete personal profiles, the system extracts and verifies cryptographic proofs of identity and location, achieving verification accuracy without retaining detailed personal information that could be exposed.
Solution Approach 2:
The patent implements local quality by allowing different levels of data disclosure for different verification purposes. Users can selectively reveal only the specific attributes needed for each verification context (e.g., proving age without revealing birthdate, proving location without revealing precise coordinates), maintaining verification accuracy while minimizing privacy loss through selective disclosure.

AI summary
Systems and methods described herein are directed to using a distributed ledger network and devices that transmit secured representations of distributed ledger addresses to prove the custody of an asset by a user at a particular location and time. In some implementations, a method includes: transmitting to a server system operating as a node on a distributed ledger network: a first secured representation of a distributed ledger address associated with a first location; a second secured representation of a distributed ledger address associated with an asset; and a third secured representation of a distributed ledger address associated with a user; and receiving a confirmation message from the server system.
