A key challenge in litigation is verifying that all relevant case content has been produced. Adding to the challenge is the fact that litigating parties are both bound to produce relevant documents and bound to protect private information (e.g. medical information). This leaves open the possibility of withholding content inappropriately, and verifying that this has not occurred is a time-consuming process involving the presiding judge. We introduce testable commitments; a cryptographic technique for verifying that only the right information has been withheld without the need for a trusted third party. We present two constructions of testable commitments and discuss an implementation of one of the constructions.
