What is the Graphometric Signature?
The Graphometric Signature captures a handwritten signature on a digital device, such as a tablet or signature pad, and records the biometric traits of the gesture itself: pressure, speed, stroke order, acceleration and pen angle. This turns a familiar, natural act, signing your name, into strong biometric evidence.
How it works with Quantidia
The signatory signs directly on a tablet, signature pad or touchscreen. Quantidia encrypts the biometric data at the moment of capture and binds it cryptographically to the document, so the signature can be verified later without exposing the raw biometric information. The result carries a legal presumption of authorship comparable to an Advanced Electronic Signature.
