Blockchain Wallet Segments Encrypted Activity Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face privacy concerns when allowing their portable computing devices to continuously track their activities, as existing solutions do not effectively balance data collection with privacy protection.
Innovation Solution
The use of asymmetrical encryption, specifically private/public key encryption, combined with distributed ledger systems like blockchain, to encrypt and verify user activity data, ensuring only the user can access and decrypt their information, while maintaining an immutable record of their activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous data collection about user activities is implemented, then information completeness is improved, but privacy protection deteriorates
Solution Approach 1:
The patent segments data into two distinct categories: encrypted personal activity data stored locally on the user's device, and unencrypted metadata (timestamps, locations) stored on the server. This segmentation allows the system to maintain complete activity information while protecting sensitive personal details from server-side access, thereby resolving the contradiction between information completeness and privacy protection.
Solution Approach 2:
The patent introduces encryption as an intermediary mechanism between the user's personal data and the server. The server can store and process metadata without directly accessing encrypted personal activity data, which acts as a protective barrier. This intermediary approach enables continuous data collection while maintaining privacy through cryptographic protection.
2Object-affected harmful factors
If encrypted data storage is implemented, then privacy protection is improved, but data verification capability deteriorates
Solution Approach 1:
The patent uses cryptographic hash functions as intermediaries to enable verification without decryption. The system stores hash values of encrypted data blocks, allowing the server and third parties to verify data integrity and authenticity without accessing the actual encrypted personal information. This resolves the contradiction by providing verification capability while maintaining encryption-based privacy protection.
Solution Approach 2:
The patent replaces traditional verification mechanisms (which would require decrypting and inspecting data) with cryptographic verification methods. Instead of mechanically accessing encrypted data to verify it, the system uses mathematical hash functions that provide verification capability without compromising the encrypted state, thus maintaining both privacy and reliability.
3Reliability
If distributed ledger system is used, then data integrity is improved, but system complexity deteriorates
Solution Approach 1:
The patent segments the system into two parts: a simplified local component that handles encryption and data storage on the user's device, and a distributed ledger component that stores only metadata and verification information. This segmentation reduces the complexity burden on individual devices while maintaining the integrity benefits of distributed ledgers at the system level.
