TrustSearch: Toward Secure and Efficient Reverse Image Search via SGX

Published
Record updated

Summary

TrustSearch performs reverse image search over stored images inside an Intel SGX enclave, so the search runs on plaintext data while the enclave provides security guarantees. Because SGX has tight resource limits, directly running the search there is costly, so the authors use design approaches to reduce that overhead. Evaluated on real-world image datasets, it outperforms state-of-the-art approaches in search performance while keeping enclave space use efficient.
