KeFirma™: the graphometric signature solution on tablet
KeFirma™ is an innovative, simple, and secure system to sign documents on tablet and digitize your company documents.

How does graphometric signature work
- Your clients, suppliers, or employees sign the digital document directly on your tablet or graphics tablet connected to a computer.
- KeFirma™ detects the graphometric signature of the person who signed and proceeds with the validation of the document on the cloud.
- The document is archived on digital repository systems compliant with legal regulations, and it can be fetched whenever necessary.

KeFirma™ technology
KeFirma™ is based on graphometric technology, which means that the device on which the person signs acquires the behavioural biometric parameters that make a signature unique, such as:
- Rhythm
- Speed
- Pressure
- Acceleration
- Movement
Each document managed by KeFirma™ using graphometric signature has the maximum security level possible thanks to an asymmetric encryption mechanism.
It means that there are two keys that allow for the signature to be decrypted: the first key (public) identifies the digital print of the sender, but the recipient can decipher the message only using a second key.
The latter is preserved by a notary, who can use the key only in case of a legal dispute, to verify the authenticity of the graphometric signature.

KeFirma™ can help you in case of a legal dispute
With KeFirma™, our digital signature solution, the signature on a document is open to evaluation on a legal dispute, because it is a plain electronic signature. Compared to paper signatures, the handwritten trait is associated with biometric parameters that, in case of a legal dispute, can be evaluated by a calligraphy expert beyond the signature trait.
The system and process supporting KeFirma™ provide more information beyond the calligraphy verification, since it is possible to associate these parameters to documents:
- Univocity of biometric data for the person who signs
- The certainty of the date of the signature
- The scanning of the identity document for the person who signs
- The possibility to store the document in electronic format
- The possibility to access the private deciphering key available to the notary
