Biometric or Digitized Signature

The digitized or Biometric Signature are electronic handwritten signatures we draw on graphic tablets. However, there isn’t a single definition for these signatures in this industry. There are many different usage scenarios, for example card payments (as in Mercadona or El Corte Inglés), receiving online orders from Correos ( State-owned Spanish courier) or any other courier company, signing a car leasing agreement…

The digitized signature is the most basic and ancient version of digital signature. This is the typical paper document signature that is then scanned and collected in a digital document (jpg, pdf, etc.) and easy to forge. Although its security level is very low, it is still used in many business processes.

Biometric signature is any signature of an electronic document in which the signatory’s identity is linked to this document by capturing his biometric data, which can be of many types: iris, locution, fingerprint, etc.

There’s a specific type of biometric signature in which the data linked are those produced when physically signing on a device that can collect aspects of the signature – stroke, pressure, or speed implemented – that all together makes it unique. They are those electronic handwritten signatures we carry out on graphic tablets. There are many use case scenarios, such as in the case of paying by debit or credit card (typically in large commercial areas), receiving parcels and signing car rental contracts, etc.

As this type of signature is the most commonly used, it is generally accepted to identify the biometric signature with the collection of biometric data of the electronic handwritten signature
