> Identity verification that never sees your data. Privacy-preserving credential checks powered by Multi-Party Computation (MPC) and Zero-Knowledge Proofs (ZKP), built for the EU Digital Identity Wallet era.

Partisia Applications ApS is a Danish identity-infrastructure company spun out of Aarhus University in 2018 by researchers who pioneered Multi-Party Computation and Zero-Knowledge Proofs, including co-founder Prof. Ivan Damgård. The platform lets verifiers check identity claims (age, country, accreditation, residency, eligibility) without the verifier (or Partisia) ever decrypting the underlying personal data. It aligns with GDPR, NIS2, and eIDAS 2.0. Based in Aarhus, Denmark.

## Products

- [VisitorPass](https://www.partisia.com/products/visitorpass): drop-in identity + age gating for regulated venues and customer flows.
- [AgeVerify](https://www.partisia.com/products/ageverify): standalone age-assurance flow with no personal-data hand-off to the verifier.
- [Open Platform](https://www.partisia.com/products/platform): SDKs (TypeScript, Java, Go, Python) for building custom credential issuance + verification flows on the same MPC/ZKP primitives.

## Technology

- [Technology overview](https://www.partisia.com/technology): how decentralized identity, MPC, blockchain, Know Your AI, and quantum-safe key distribution combine into a privacy-preserving stack.
- [Decentralized Identity](https://www.partisia.com/technology/decentralized-identity): decentralized identifiers, verifiable credentials, and zero-knowledge proofs — prove a claim without revealing the document behind it. Aligned with eIDAS 2.0 and the W3C VC/DID standards.
- [Multi-Party Computation (MPC)](https://www.partisia.com/technology/mpc): jointly compute over private inputs (incl. secure data collaboration / MPC+ for cross-organisation analytics); each party learns the result and nothing else.
- [Blockchain](https://www.partisia.com/technology/blockchain): a decentralized, immutable ledger that hosts MPC smart contracts — a contract can add a privacy layer parallel to the ledger by allocating MPC nodes that compute on secret-shared inputs.
- [Know Your AI](https://www.partisia.com/technology/ai): verifiable identity, delegation, and authorization for AI agents. Decentralized identifiers and zero-knowledge proofs composed into a trust framework for autonomous systems.
- [Partisia Quantum](https://www.partisia.com/technology/quantum): MPC-based quantum-safe key distribution: keys split across independent nodes and never assembled at any single point, NIST PQC-compliant, pure software on existing infrastructure.
