One-time Signatures (Documents)

Files can be signed by the user without integration as part of a one-time process. The necessary identity verification of the user can be accomplished via two options:

1. Ident Lite by Evtrotrust via WebSDK or mobile SDK
2. Identification by Client (Third Party Reliance)

1. One-time Signatures based on Ident Lite by Evrotrust

This workflow enables users to digitally sign documents without requiring a full Evrotrust account integration. The process leverages Ident Lite, Evrotrust's streamlined identity verification service, to establish the signer's identity before issuing a qualified electronic signature.

How it works:

The signing process is split into two phases:

1. Identity Verification: The user completes a one-time identity verification via Ident Lite using either the WebSDK (for enhanced eID verification) or mobile SDK (for enhanced or basic identification levels)
2. Document Signing: Once verified, the user can sign the document(s) within a 2-hour validity window

Key characteristics:

• Time-sensitive: Signatures must be completed within 2 hours of the Ident Lite verification
• No account required: Users don't need an existing Evrotrust account
• Flexible verification: Choose between web-based eID scanning or mobile app verification
• Compliance: Meets eIDAS requirements for qualified electronic signatures with proper identity assurance

This approach is ideal for scenarios where users need to sign documents occasionally or as part of isolated business processes, without the overhead of account creation and management.

2. One-time Signatures based on Identification via Client

This workflow allows organizations to leverage their own Know Your Customer (KYC) processes for identity verification, with Evrotrust relying on the identification performed by the Client. In this model, the Client acts as a Registration Authority to Evrotrust, enabling document signing based on existing customer relationships or in-person verification procedures.

How it works:

The signing process follows these phases:

1. Identity Verification: The Client verifies the user's identity through their own KYC procedures (either at the current moment face-to-face or based on historical identification)
2. RA IDV Statement: A registration agent from the Client organization provides a signed RA IDV statement to Evrotrust.
3. Document Signing: Once the declaration is processed, the user can sign the document(s)

Key characteristics:

• Leverage existing KYC: Utilize your organization's established customer identification processes
• No duplicate verification: Users already identified by the Client don't need to repeat identity checks
• Third-party reliance: Evrotrust trusts the Client's identification procedures and acts upon the Registration Authority declaration
• Two implementation options: RA IDV statement can be signed within the Evrotrust app or signed separately and uploaded via API
• Compliance: Meets regulatory requirements through delegation to the Client as Registration Authority

This approach is ideal for financial institutions, government agencies, or other organizations with robust existing KYC processes who want to extend qualified electronic signature capabilities to their verified customer base without redundant identity checks.
