Trust Stamp, Partisia, and Digital Platformer have signed a commercial agreement to deploy privacy-preserving biometric identity verification in Japan’s financial services sector and the broader Asia-Pacific region. The three-party deal combines Trust Stamp’s Fuzzy IT² biometric tokenization with Partisia’s multi-party computation (MPC) platform in an architecture designed to ensure that no single entity, including the identity service provider, can access a user’s confidential data.
Under the technical design, a privacy-preserving biometric token is generated on the user’s device. An MPC-based facial matching and signing process then executes using a secret-shared private key. The resulting identity tokens are split into secure shares distributed across multiple MPC nodes, ensuring they are never reassembled at any single location during comparison. The approach also reduces dependence on any single point of failure. Target sectors include financial services, insurance, healthcare, and government.
“This collaboration is grounded in a shared commitment to advancing both security and usability across the digital economy,” said Gareth Genner, CEO of Trust Stamp. Ikkei Matsuda, CEO of Digital Platformer, said the partnership marks “a significant step toward redefining digital identity and financial security.” Mark Medum Bundgaard, Chief Product Officer at Partisia, said the company’s MPC technology “was designed precisely for challenges like this: sensitive data must be processed with full verifiability but zero exposure.”
The Japan deployment commercializes Trust Stamp and Partisia’s MPC biometric partnership first announced in May 2025, which combined Trust Stamp’s irreversible biometric tokenization with Partisia’s encrypted MPC architecture. Digital Platformer had already established a working relationship with Trust Stamp through an earlier bilateral partnership announced in February 2025 before the three-way Japan agreement was signed.
The partnership enters a market shaped by ongoing reform. Japan’s digital identity opening to private-sector applications is accelerating, with the Digital Agency having authorized private use of My Number Card IC chips in early 2026. Digital Platformer was founded in Tokyo in 2020 and specializes in blockchain-based trustless identity solutions and digital asset transaction security. Trust Stamp is an AI-powered identity services provider operating across banking, finance, compliance, and healthcare in more than 20 countries. Partisia is an MPC specialist focused on enabling secure data collaboration without exposing confidential data to any processing party.
