# Trusted LTANS — Mobile-ID Long-term Preservation. Verifiable Digital Evidence. Trusted LTANS combines intake, lifecycle governance, cryptographic evidence, verification, renewal and transfer. DMS manages records; backups restore copies; a TSA binds a digest to time; LTANS maintains evidence and lifecycle accountability. Choose a managed service or customer infrastructure and provider-managed, customer-managed or hash-only custody. Agree byte/key ownership, durable reread access, TSA sources and exit conditions before integration. Digests alone do not supply originals. Mobile-ID announced its RAR Center contract for VNeID SSO/ShareInfo. GoPaperless SSO supports identity journeys; RS-HUB and CA/TSA connections follow authorization and service scope. LTANS connector configuration and acceptance are confirmed per environment. RFC 4810, ERS/XMLERS and PKI references have distinct design scopes; LTAP is an expired Internet-Draft. Organizational ISO/IEC 27001 and component certificates do not themselves certify Trusted LTANS or QTSP status. Start with synthetic data, custody and PoC criteria. Website documentation describes integration designs/contracts; service levels follow approved agreements. Contact info@mobile-id.vn · 1900 6884 · +84 28 3622 2982.
