Auditable cross-domain data sharing via threshold secret sharing and zero-knowledge proofs

This research paper proposes a method for securely sharing data across different organizations or systems using threshold secret sharing (a technique where data is split into pieces so that a minimum number of pieces are needed to reconstruct it) and zero-knowledge proofs (cryptographic methods that let one party prove something is true without revealing the actual information). The approach aims to allow data sharing while maintaining auditability, meaning organizations can track and verify that data was shared appropriately.
