Abstract

Data may contain personal information and be subject to privacy requirements. The data may be encrypted and only a secure enclave may be able to decrypt the encrypted data. The secure enclave may be used to generate a report based on the encrypted data and a first set of added noise. The report may be subject to audit requirements and satisfy a differential privacy guarantee. The encrypted data may be stored for a first period. After the first period, the secure enclave may be used to generate a private synopsis based on the encrypted data and a second set of added noise. The private synopsis may satisfy the differential privacy guarantee. The private synopsis may be encrypted and only the secure enclave may be able to decrypt the encrypted private synopsis. The encrypted data may be expunged, and the encrypted private synopsis may be retained for a second period.
