A trust journey architecture
Choice of building blocks, proof sequence, decision points, logging and interfaces with your existing IS.
Digital trust
Digital Trust — e-KYC, eIDAS electronic signature, EUDIW e-wallet and fraud prevention
Identity verification, strong authentication, electronic signature, fraud prevention. The critical building blocks of your digital journeys.
Observation
When trust becomes an architectural constraint.
Regulation becomes a product constraint
eIDAS 2, PVID, AI Act, DORA, AML/CFT, Open Banking: requirements become architecture constraints, not checkboxes.
Every flow is an attack surface
Identity, signature, payment: a poorly secured or non-compliant journey is enough to trigger a major security or regulatory incident.
Fraud evolves faster than tools
Deepfakes, document injection, behavioural attacks: detection cannot be static or delegated to a single tool.
Strengthen security without ruining the journey
Each added step can either protect the journey or break conversion. The trade-off must be arbitrated end to end, not step by step.
Three trust territories
Identity & Access
Identity verification (e-KYC, PVID, ANJ/ACPR/AML journeys), European EUDIW e-wallet (eIDAS 2.0, PID/QEAA attestations, OpenID4VC/VP), strong authentication (adaptive MFA, FIDO2, OpenID Connect, SSO, FranceConnect+).
Engagement & Proof
Electronic signature at the three eIDAS levels (simple, advanced, qualified), qualified sealing and timestamping, evidentiary digital safe, complete traceability and legal admissibility.
Flow Protection
Fraud prevention (real-time scoring, liveness detection, deepfake detection, document analysis), Open Banking PSD2 (AISP, PISP, SCA), PKI and cryptography (X.509 certificates, TLS/mTLS, code signing, encryption).
AVANT Situation fréquente
- Conformité rattrapée en urgence Audits de dernière minute, refontes coûteuses, mises en production retardées.
- Empilage d'API tierces KYC d'un côté, signature de l'autre, fraude ailleurs. Aucun fil conducteur.
- Preuves discontinues Traces partielles, archivage isolé, dossier audit fragmenté.
- Friction parcours utilisateur Chaque contrôle ajouté fait chuter la conversion sans renforcer la confiance.
APRÈS Avec REELIANT
- Conformité posée dès l'architecture Niveaux de preuve définis, exigences traitées en conception, pas en rattrapage.
- Chaîne de confiance unifiée Identité, wallet, signature, fraude orchestrés dans un même flux cohérent.
- Preuve continue et opposable Trace d'audit complète, archivage probant, dossier défendable à tout moment.
- Sécurité sans friction Contrôles arbitrés selon le risque réel, parcours fluide, conversion préservée.
Chain of trust
From first contact to legal archiving.
Each step corresponds to a distinct responsibility and an admissible proof. The full chain remains traceable and defensible.
PVID
Identity verification
Document control, liveness detection. ANJ, ACPR, AML/CFT journeys.
E-wallet
Credential storage
EUDIW, PID/QEAA credentials. Portability and user control.
Signature
Provable consent
Simple, advanced or qualified eIDAS. Multi-party contractual journeys.
Sealing
Legally binding archiving
Qualified timestamping, digital safe, complete audit trail.
What we deliver
What must be clear before a critical journey goes live.
02
A regulatory and evidence framework
Signature levels, identity requirements, audit trail, admissibility conditions and control points made explicit.
03
Integrated fraud and authentication controls
Liveness, scoring, MFA, PKI, signature or wallet integrated as one coherent journey, not as a loose stack of tools.
04
Go-live and operating conditions
Runbook, supervision, evidence handling and governance. The journey remains defensible over time, not only on launch day.
Proof in production
Regulated journeys already live in production.
Signature, identity, wallets and fraud are won in the integration details as much as in the choice of components.

Frequently asked questions.
What is digital trust?
The set of mechanisms that guarantee an identity has been verified, consent is traceable and a document or transaction has legal standing: KYC, e-signature, PKI, fraud prevention.
What are eIDAS 2.0 and the European digital wallet (EUDIW)?
eIDAS 2.0 is the European regulation requiring each member state to provide a digital identity wallet (EUDIW) by 2026. It allows citizens to store and present verifiable credentials (PID, QEAA) via OpenID4VC/VP protocols.
What is the difference between simple, advanced and qualified e-signatures?
A simple signature timestamps consent; an advanced signature binds the signatory in a verifiable way; a qualified signature (eIDAS) has the same legal standing as a handwritten signature and requires a certificate issued by a qualified trust service provider (QTSP).
How do you secure a KYC journey against deepfake fraud?
Through a chain combining real-time liveness detection, document metadata analysis, behavioural scoring and cross-referencing with reference databases, without relying on any single tool.
What do you deliver on a digital trust project?
We deliver the journey architecture, the proof and control choices, the required integrations, the expected audit trail and the operating conditions. A digital trust subject cannot be left to loose API assembly.
Critical journeys to secure?.
We have already handled these cases. A first conversation is enough to frame the target architecture and the regulatory perimeter.
