Data privacy issues and regulations are on the rise. Privacy and transparency concerns are quickly defining a new era in data management and service operation across applications, platforms and industries. With a continuous flow of revisited privacy laws worldwide, adopted in different regulations such as the General Data Protection Regulation (GDPR), the urge to enhance transparency, and provide efficient and dynamic control over individual consent to use personal data, has peaked. Importantly, data-centered service providers must implement tools and integrate frameworks that are accessible, with reliable updates and viability assurances across the entire information life cycle. Data transparency and consent management platforms become then an essential tool that allows service providers to communicate their privacy practices and build up users' trust, while giving consumers enhanced control over their privacy preferences. In this context, we present a consent management system based on multiple blockchains. We assure a scalable user-friendly solution using a web-based blockchain model, performing a decentralized solution and a separation between the private data and consent data for more security and privacy assurance.
