Abstract
Aspects and features of the present disclosure can provide a trusted, privacy-preserved deduplication process by executing deduplication functions in a trusted execution environment (TEE). In some examples, encrypted, incoming user data blocks are decrypted in the TEE to produce unencrypted user data blocks. An incoming digital fingerprint or each unencrypted user data block is produced. A processing device can compare the incoming digital fingerprint to existing digital fingerprints stored in the TEE to determine a presence of the incoming digital fingerprint and hence the presence of a copy of the data block in the storage platform, and writes the encrypted. Incoming data blocks are written to storage only when necessary. The technique allows public mass storage systems to meet cybersecurity objectives while achieving the storage space efficiency that deduplication provides.
