The Data Empowerment and Protection Architecture (DEPA) enables people to seamlessly and securely access their data and share it with third-party institutions. But the proposed consent management solutions force data owners to trust intermediaries, resulting in a lack of user-centricity and making the process prone to censorship.
To overcome these issues, we have developed a decentralized consent management solution using permissioned blockchain. The goal of decentralized consent management is to provide data owners and other parties, an automated and trusted framework to manage data consent. The consent lifecycle is managed through smart contracts, which can be upgraded as and when required by the owner.
The decentralized consent management solution can be deployed in any ecosystem where Data Protection and Empowerment Architecture is applicable; i.e., there is a need to manage consent through the data owner. These sectors include Finance, Telecom, Healthcare, Urban Exchange Framework, etc.
Further it can facilitate data exchange by charging a nominal fee. However, since most individuals are accustomed to free services, we could subsidise or relinquish the service fee charged to the data principals by charging the data users (much like a subscription model).
