The probative value of an electronic signature in finance hinges on three fronts: demonstrating strong customer authentication (DSP2 SCA), proving compliance with legal deadlines (Scrivener, waiver, withdrawal), and guaranteeing contract integrity in archived form in case of ACPR/AMF audit.
Certyneo delivers for each signature an audit certificate embedded in the PDF, which aggregates technical evidence:
- Signatory identity (email + phone verified by OTP — DSP2 SCA compatible)
- Qualified timestamp of each action (sending, viewing, signing, refusal)
- SHA-256 cryptographic fingerprint of the signed document
- IP and rough geolocation of the signatory
- Detailed log of reminders and notifications
- Traceability of legal deadline (Scrivener reflection, withdrawal, waiver)
This body of evidence meets the requirements of Article 1366 of the Civil Code, the eIDAS regulation, and supervisory authorities (ACPR, AMF). In case of audit or client dispute, the audit trail constitutes direct admissible evidence.
