Extensible Consent Management Architectures for Data Trusts

Sensitive personal information of individuals and non-personal information of organizations or communities often needs to be legitimately exchanged among different stakeholders, to provide services, maintain public health, law and order, and so on. While such exchanges are necessary, they also impose enormous privacy and security challenges. Data protection laws like GDPR for personal data and Indian Non-personal data protection draft specify conditions and the $\mathit{\text{legal}}\mathit{\text{capacity}}$ in which personal and non-personal information can be solicited and disseminated further. But there is a dearth of formalisms for specifying legal capacities and jurisdictional boundaries, so that open-ended exchange of such data can be implemented. This paper proposes an extensible framework for consent management in Data Trusts in which data can flow across a network through “role tunnels” established based on corresponding legal capacities.
