Abstract:
The need to protect sensitive business and personal information while adhering to data protection regulations, along with the exponential growth of digital data, presents a significant challenge. Data sovereignty addresses this challenge by focusing on safeguarding data across different domains, such as business and healthcare. This objective is accomplished through the specification of Usage Control policies, implementation of data anonymization techniques, and enhancement of policy enforcement in distributed systems. In this work we present a data sovereignty solution that enhances the capabilities of the XACML framework within a data sharing ecosystem. When this solution is realized, the data providers can benefit from dynamic enforcement of Multiparty Computation (MPC) by specifying MPC-enabling policies. Following this approach, the data providers who seek to collaboratively compute a function over their inputs while keeping those inputs private can enforce MPC by specifying a c
orresponding policy at runtime. Resulting in heightened security and privacy preservation, our solution motivates data providers to engage in data sharing.
