SIGPAD AND GRAPHOMETRIC SIGNATURE
Sigpad and graphometric signature
The Graphometric Signature on tablets is a great innovation, because it allows the "ab-origin" digitization of all documents and a consequent increase in the efficiency of business processes in compliance with the GDPR, reduces the use of paper and improves the corporate image.
The Graphometric Signature (FEA) is an electronic signature method created with a manual gesture completely analogous to the handwritten signature on paper. The execution of a Graphometric Signature allows to collect unique and personal data connected to the subscriber through a device, tablet or pad, capable of dynamically acquiring the movement of a stylus - operated directly by a person's hand - on a sensitive surface (similarly to a pen on the paper).
During signature, signature signature information, such as speed and pressure, are securely stored in the document, and can later be assessed by a handwriting expert, similar to the handwritten signature. The transfer of data from the tablet to the PC is encrypted, in this way it is impossible to spy on the biometric characteristics. Biometrics could be encrypted inside the pad using an RSA public key.
The data thus collected are then processed and attached to the IT document (typically PDF) in order to guarantee:
- identification and univocal connection to the signatory;
- the univocal connection of the signature to the signed document;
- the possibility of verifying that the signed electronic document has not undergone changes since the signature was affixed.
After confirmation, the document signed with the software is automatically archived and can be recalled at any time.
This application is reflected in a wide variety of applications such as identity documents and all documents that need to be signed in order to be validated.
The graphometric signature described above therefore represents a particular form of Advanced Electronic Signature - as defined by the latest edition of the Digital Administration Code and the related Technical Rules - and has the same legal value as the handwritten signature.
This is thanks to the fact that it allows the identification of the user through the recording of unique graphometric parameters - such as rhythm, acceleration, movement, pressure, speed - connected unequivocally to the subscriber.
