Resource Title Using zero-knowledge proofs in a blockchain-based distributed ledger for privacy and verifiability of identities in health research
Date Issued 04 September 2023
Abstract Participants in health research are often given compensation and/or reimbursement as incentives to participate and cover the costs incurred in participation. This process would involve third-parties whether in auditing or disbursement and could be a concern for the participant’s privacy. Therefore, there is a need to balance between the participant’s privacy as well as the ability to verify participant identities to prevent fraud. A solution using a blockchain-based distributed ledger and zero-knowledge proofs was explored. The study used Ethereum as the blockchain-based distributed ledger platform and Zokrates for generating and verifying zero-knowledge proofs. The study showed that it is able to provide protection against replay attacks, impostor attacks, and identity linking. Additionally, due to the system’s design, collusion resistance was also guaranteed to a certain degree. We have also tested the performance of the explored solution and it is shown that, while it does not meet theoretical expectations, it is acceptable in practical usage.
