Private Set Intersection (PSI)

PSI is a cryptographic protocol allowing two parties to compute the intersection of their datasets without revealing any other elements. At TrustedMatch, we support both hashing‑based PSI (Bloom filters) for large volumes and advanced MPC‑based PSI for high‑security jobs.

Secure Enclave Technologies

We process pseudonymized data inside hardware‑enforced enclaves to guarantee confidentiality. Our current providers include:

• AWS Nitro Enclaves – isolated, hardware‑level VMs for sensitive workloads.
• Azure Confidential Computing – Intel SGX‑based secure enclaves on Microsoft Azure.
• IBM Confidential Computing – robust, tamper‑resistant enclaves for critical data.

Integration Tips

Combine PSI and secure enclaves to maximize privacy. Always run a GDPR “balancing test” to document legitimate interest, and choose solutions that scale with your dataset size.
