TECHNICAL REFERENCE
Architecture Center
Technical entry point for CTOs, CISOs and Chief Architects: system landscape, trust boundaries,
security, evidence, deployment and integration.
System Landscape
Experience channels reach subject/process orchestration through an integration/API edge;
document/eID/biometric/authoritative-source methods produce results, and policy/assurance turns
them into decisions/evidence for relying parties.
Trust Boundaries
Separate user/device, customer client, CheckID ingress/core, authoritative/third-party sources,
evidence layer and customer enterprise systems, with owner/trust assumptions per boundary.
Identity Proofing Architecture
Subject/process contracts, evidence acquisition, holder binding, policy and results are
connected without collapsing authentication or identification into proofing.
Security Architecture
Current API authentication is OAuth2 Client Credentials + Bearer. TLS/mTLS, data-at-rest
encryption, HSM, tenant isolation and privileged-access claims require separate security
evidence.
Evidence Architecture
Correlation uses subject/process/billcode identifiers where the contract exposes them. Integrity
and retention mechanisms remain source-bound.
Deployment and Operations
HA/DR/RTO/RPO/scale are NFR/contract values; the architecture center presents models and
responsibilities without inventing numbers.
