SECURE MULTI-PARTY COMPUTATION (MPC)

Collaborate on AI Without Compromising Data Sovereignty

Engineer cryptographic protocols for joint AI model development across organizations without exposing raw data.

Enable cross-enterprise AI collaboration where insights are shared, but sensitive datasets never leave their sovereign control. Our MPC engineering services build the cryptographic infrastructure for secure, multi-party AI training and inference.

We design and implement distributed protocols using frameworks like MP-SPDZ and Obliv-C that allow multiple entities to:

  • Train a shared model on their combined datasets without any party seeing another's raw data.
  • Perform joint inference on encrypted inputs, revealing only the final aggregated result.
  • Maintain cryptographic proof of data privacy for regulatory compliance (GDPR, CCPA).

This is the foundational layer for privacy-preserving consortium AI in sectors like:

  • Financial Services: Collaborative fraud detection across banks.
  • Healthcare: Multi-institutional research on patient data.
  • Supply Chain: Optimizing logistics with partner data while protecting trade secrets.

Business Outcomes of MPC-Powered Collaboration

Our Secure Multi-Party Computation (MPC) Engineering service enables strategic data partnerships without the legal and security risks of raw data sharing. We build cryptographic protocols that allow you to train superior AI models with partners, competitors, or suppliers while keeping all source data private and secure.

01

Unlock New Data Partnerships

Collaborate with industry peers, research institutions, or supply chain partners on joint AI initiatives. Our MPC protocols enable training on combined datasets for richer insights, while cryptographic guarantees ensure no party can access another's raw data. This removes the primary legal and competitive barrier to data collaboration.
