Verifiable Credentials & Digital Identity Security
Security advisory and assurance for national digital identity programmes, verifiable credential infrastructure and open-source DPI identity stacks — with practitioner expertise in MOSIP, OpenG2P, GovStack, W3C VC, DID standards and eIDAS 2.0 across Africa, Asia and the Pacific.
National digital identity programmes consolidate sensitive personal data — biometrics, demographic records, linkages to benefit payments, healthcare and financial accounts — into a single foundational infrastructure. A breach is not just a data incident: it can undermine public trust in the entire programme, expose millions of citizens to identity fraud, and create regulatory and diplomatic consequences that take years to resolve.
Nucleus Systems brings specialist expertise in the security of the open-source DPI identity platforms being deployed at scale across Africa, Asia and the Pacific — MOSIP (Modular Open Source Identity Platform), OpenG2P (social protection delivery), and the GovStack identity building block. Our practitioners have worked inside these systems, understand their architecture and trust boundaries, and can assess and advise on security in ways that general security consultants cannot.
We also cover the verifiable credential and decentralised identity layer — W3C Verifiable Credentials, DID standards, selective disclosure schemes, and the eIDAS 2.0 European Digital Identity Wallet framework — advising governments, issuers and relying parties on secure implementation of the emerging digital identity trust infrastructure.
Services
From national ID programme security architecture through to verifiable credential system assessment and eIDAS 2.0 compliance advisory.
Digital Identity Security Architecture Review
End-to-end security architecture assessment of digital identity systems — covering registration, biometric capture, deduplication, authentication, credential issuance, and relying party integration. Threat model built to the specific programme context and deployment environment.
MOSIP Platform Security Assessment
Purpose-built security assessment for MOSIP deployments — covering the registration client, kernel services, ID repository, authentication server, resident portal, and partner management. Based on direct platform expertise, covering the MOSIP-specific threat model and known vulnerability classes.
OpenG2P Security Review
Security assessment of OpenG2P deployments for social protection and benefit delivery programmes — covering beneficiary registry security, payment disbursement controls, ID-to-payment linkage integrity, and the specific fraud and exclusion risks in social protection digital delivery.
Verifiable Credential System Assessment
Security assessment of verifiable credential issuance, presentation and verification infrastructure — covering W3C VC data model implementation, DID resolution and key management, credential status mechanisms, selective disclosure implementation, and holder binding security.
Decentralised Identity Infrastructure Review
Security review of DID method implementations, VDR (verifiable data registry) security, key rotation and recovery procedures, and the governance frameworks that underpin decentralised identity trust. Covers enterprise, government and cross-border DID deployments.
Biometric System Security Assessment
Security assessment of biometric capture, storage, matching and deduplication systems — covering biometric data protection, liveness detection and presentation attack resistance, biometric template security, and compliance with ISO/IEC 30107 and applicable data protection regulations.
National ID Programme Security Advisory
End-to-end security advisory for national digital ID programme design and implementation — from initial threat modelling and architecture review through to procurement security requirements, vendor assessment, pilot security, and operational security design for national-scale rollout.
eIDAS 2.0 & Privacy-Preserving Design
Advisory for eIDAS 2.0 European Digital Identity Wallet compliance — covering EUDIW architecture requirements, PID (Person Identification Data) attestation security, and selective disclosure. Also privacy-preserving identity system design for programmes that must balance verifiability with minimal disclosure and anti-surveillance principles.
