MOSIP Identity-Management Platform

Biometrics with PKI trust

A proof-of-concept identity-management stack on the open-source MOSIP standard — the platform behind national-ID programmes — with biometric capture on a Raspberry Pi 4 device server and certificate-chain trust securing identity at every stage.

help The problem

National-scale identity systems cannot just capture biometrics — every capture device must be trusted, and every identity record must be verifiable as it moves through enrolment, storage and authentication. MOSIP is the open-source standard several countries build national ID on, and it enforces exactly this: certified devices, signed data and authority-verified trust chains.

build What we built

  • A MOSIP-compliant device server on Raspberry Pi 4 in Java and C, capturing fingerprint, iris and face biometrics.
  • Certificate-chain and authority verification throughout: identity data is stored, loaded and verified against the PKI trust chain at each stage, so no unsigned device or tampered record passes.
  • A management server in Java Spring Boot — the backend of the identity system.
  • A background desktop service for device monitoring and a desktop UI client driving the device server's and desktop service's APIs.

check_circle The result

  • done A working PoC demonstrating the full MOSIP pipeline — trusted capture on real hardware through PKI-verified storage and verification to the management backend.
  • done Security engineering, standards compliance, biometric-device integration and backend development — proof the skill set extends from bare-metal firmware up through secure backend systems.
