Summary:
|
Distributed ledger technology has achieved wide applications in industries, considering its decentralization, tamper-proof features. Current approaches for sharing business data and PII data with companies and digital platforms lead to privacy vulnerabilities from hacks or poor data management. Adopting DLT/blockchain in data sharing management allows individuals or companies to maintain more direct control over their own confidential information. In the DLT-based solution, only non-PII data, e.g. hashed data values, are stored in the on-chain. PII data about data owner are stored in the offchain. DLT-based solution provides a way that improves the traceability of data, verifiability of data, and changeability of data status. In this context, this recommendation is to specify the security architecture of data sharing management based on in distributed ledger technologies. Based on the architecture, it specifies the interfaces between the functional entities and the procedures of data sharing management based on DLT.
