The Graphometric Signature is a type of Advanced Electronic Signature (AES), obtained by capturing the biometric data of a user and binding it indissolubly to a document to be signed.

What is a Graphometric Signature?
A Graphometric Signature is a set of data collected when a user signs a document on a tablet or smartphone. This data is then encrypted and stored along with the signed document.

How does a Graphometric Signature work?
Signing with a Graphometric Signature involves a specific series of steps: first, the signer is identified using a valid identification document, which is then linked to their signature. This is followed by exclusive control by the signer over the signing system and the ability to verify that the document has not been modified after the signature was applied. This process ensures the authenticity of the signature and protects the signer.

Does the Graphometric Signature have legal value?
Applying this type of Advanced Electronic Signature allows the creation of digital documents with full legal validity, minimizing both manual operations and paper use. This paperless solution reduces the environmental impact associated with document completion and signing, while also speeding up and simplifying the procedures required for proper document archiving.
