Abstract
A secure enclave may be used to satisfy privacy requirements and audit requirements. Code may be loaded into the secure enclave. The code may generate a predefined report based on data and added noise. The pre-defined report may be subject to audit requirements. The data may be subject to the privacy requirements. The secure enclave may generate an encryption key and a decryption key based on the code. Only the secure enclave may have access to the decryption key. And the secure enclave may allow only a verified copy of the code to access the decryption key. With the added noise, the report may satisfy a pre-defined differential privacy guarantee. Encrypting the code and ensuring that the report satisfies the differential privacy guarantee may satisfy the privacy requirements. Retaining the report, the code, the secure enclave, and the encrypted data may satisfy the audit requirements.
