What is<\/span>
an electronic seal?<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

An electronic seal is the digital equivalent of a corporate stamp applied to a document. It enables the issuer to be identified with certainty and ensures that the content has not been altered since its issuance.<\/p>\n

Any subsequent alteration is immediately detectable, making it a recognised evidentiary mechanism in cases of fraud, inspection or litigation.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

\n
\n
\n

Electronic seal: <\/span>
how does it work?<\/h2>\n<\/div><\/div>\n\n

The client application transmits the document to be sealed to the Evidency service via API, which applies an electronic seal using the certificate of the issuing organisation.<\/p>\n

The document is then timestamped to establish a reliable date and returned to the client application as a sealed and timestamped file, ready to be used and retained for evidential purposes.<\/p>\n<\/div><\/div>\n<\/div>\n\n

An electronic sealing solution
\n<\/span>designed for developers<\/h2>\n<\/div><\/div>\n\n

The electronic seal integrates directly into your applications to guarantee the origin and integrity of your documents. Implementation is facilitated through a REST API, a dedicated sandbox and SDKs, designed to simplify interactions with the Evidency platform and to accommodate your technical constraints.<\/p>\n

eIDAS-compliant electronic seal<\/h3>\n

With a single API call, a PDF document is sealed in accordance with ETSI EN 319 142 (PAdES), as referenced by the eIDAS Regulation. The service allows either the application of the Evidency seal as a trusted third party or the application of a seal in the name of your organisation.<\/p>\n

This latter option requires the use of a certificate issued by a certification authority, a step for which our teams provide support (in particular for the generation of the required technical prerequisites, such as the CSR).<\/p>\n

Time savings for your technical teams<\/h3>\n

Evidency services are designed to reduce development effort and enable your teams to focus on business integration. API call examples are available in several programming languages to secure and accelerate implementation.<\/p>\n<\/div><\/div>\n\n

Preventing attempts at document fraud<\/h3>\n

The electronic seal acts as a deterrent against the alteration, manipulation or substitution of digital documents.
By sealing the content at the time of issuance and linking the document to the identity of the issuer, it enables any modification to be detected immediately and limits subsequent challenges.<\/p>\n

Ensuring document compliance and traceability<\/h3>\n

Compliant with the eIDAS Regulation and delivered by a Qualified Trust Service Provider (QTSP) qualified by ANSSI, the Evidency service operates within a legal framework recognised under French and European law.
The qualified timestamp associated with each seal enables operations to be traced over time and, where appropriate, the production of evidentiary material usable in the context of an inspection, audit or litigation.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
