Consentio: Managing Consent to Data Access using Permissioned Blockchains

TL;DR

Consentio is a scalable blockchain-based system that enables efficient management and auditing of data access consent, supporting high throughput and low latency for large-scale deployments.

Contribution

We introduce Consentio, a novel permissioned blockchain system that ensures scalable, efficient, and auditable consent management for personal data access.

Findings

Handles up to 6,000 access requests per second

Achieves high throughput and low latency

Scales to large deployments

Abstract

The increasing amount of personal data is raising serious issues in the context of privacy, security, and data ownership. Entities whose data are being collected can benefit from mechanisms to manage the parties that can access their data and to audit who has accessed their data. Consent management systems address these issues. We present Consentio, a scalable consent management system based on the Hyperledger Fabric permissioned blockchain. The data management challenge we address is to ensure high throughput and low latency of endorsing data access requests and granting or revoking consent. Experimental results show that our system can handle as many as 6,000 access requests per second, allowing it to scale to very large deployments.
