A Policy-Based Conjunctive Scheme for Digital Forgetting of Co-Owned Data

This academic paper from ACM Transactions on Privacy and Security presents a policy-based conjunctive scheme, a method for managing the deletion of data that is owned or controlled by multiple parties. The research addresses the challenge of 'digital forgetting' (the ability to completely remove data from systems), which becomes complicated when more than one person has rights or claims to that data. The paper proposes a framework using policies (rules that determine who can do what) to coordinate data deletion across co-owned datasets.
