Worked on ProvableHQ/snarkVM, implementing ownership-aware filtering in the record finding workflow to enhance both security and efficiency. The approach involved refactoring backend logic to pre-filter records by ownership before attempting decryption, ensuring that only records owned by the requester are processed further. This change reduced unnecessary computation and exposure of unrelated data. A targeted test was added to confirm that only owned records are returned and that unrelated view keys yield no results, providing robust validation of the new logic. The work leveraged Rust and cryptography skills, focusing on backend development and secure data handling within the repository’s core systems.
