Blockchain Pointer Records for Secure User Data Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently and compliantly managing user data in digital transactions due to overlapping and conflicting regulatory requirements for fraud prevention and personal privacy protection, particularly in global financial systems.
Innovation Solution
User data is partitioned into multiple components and stored across different storage locations, with encoded addresses recorded in blockchain-based pointer records, allowing authorized access and reconstruction only when both components are combined, ensuring compliance with regulatory requirements and privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user data is stored in a centralized manner to facilitate easy access, then ease of operation is improved, but data security and privacy protection deteriorate
Solution Approach 1:
The user data is divided into multiple data portions that are stored at different locations (on-chain and off-chain). No single location contains the complete user data, thereby eliminating centralized storage while maintaining accessibility through the blockchain-based pointer record system.
2Productivity
If complete user data is stored at a single location for efficient retrieval, then productivity is improved, but data security and regulatory compliance deteriorate
Solution Approach 1:
User data is segmented into multiple portions stored at different locations. The blockchain-based pointer record stores references to these portions, enabling efficient retrieval by accessing the pointer record and reconstructing data from the distributed portions without requiring centralized storage.
Solution Approach 2:
The blockchain-based pointer record acts as an intermediary between the user data portions stored at different locations and the authorized parties requesting access. It provides a centralized reference mechanism that enables efficient data retrieval while maintaining the security benefits of distributed storage.
3Adaptability or versatility
If detailed user data is stored to fulfill regulatory requirements, then compliance with regulatory requirements is improved, but personal privacy protection deteriorates
Solution Approach 1:
User data is divided into multiple portions that can be selectively accessed and reconstructed based on regulatory requirements. Authorized parties can retrieve specific portions of data needed for compliance without accessing the complete data set, thereby reducing privacy risks while maintaining regulatory compliance.
Solution Approach 2:
The system enables partial access to user data portions only when and where required by regulatory requirements, rather than providing complete data access. This partial action approach allows compliance with minimum regulatory standards while protecting unnecessary personal information.
4Reliability
If user data is stored in multiple locations for security, then data security is improved, but device complexity and storage management complexity deteriorate
Solution Approach 1:
The blockchain-based pointer record serves as an intermediary that simplifies the management of distributed data portions. It stores centralized references to the data locations, abstracting the complexity of distributed storage from users and enabling straightforward data retrieval without manual management of multiple storage locations.
Data Source
AI summary
Method and apparatus for protecting confidential user data associated with a User. The user data are partitioned into portions which are stored in different memory locations, each portion insufficient to facilitate reconstruction of personally identifiable information without use of each of the remaining portions. A storage address for at least one portion is encoded and incorporated into a minted non-fungible asset (NFA) recorded to a distributed blockchain and placed in a User digital wallet. To subsequently reconstruct and access the user data, the storage address from the NFA is decoded, and the portions are retrieved from memory and recombined. A secure communication link facilitates authorized access to the reconstructed user data. Main and associated wallets may be used to track original and updated NFAs. The storage address may be in the Interplanetary File Storage (IPFS) system. The user data may be destroyed by erasing at least one portion from memory.
