How to create a handwritten signature within electronic signing?

The handwritten signature has its origin in ancient times. For thousands of years up until relatively recent times, this handwritten graph had barely evolved. After the digitisation of processes, including especially those related to the acceptance of the content of a document, the handwritten signature has been digitised.

The digital evolution of the handwritten signature culminated some time ago in the electronic signature concept. This legal concept, equivalent to the handwritten signature, collects a series of electronic data that are unequivocally linked to a digital document.

The structure that the electronic signature demands and the different methods for it to be legitimate in the digital format can vary, from the electronic signature based on the person’s biometric patterns to coordinate cards or NFC devices.

# The handwritten signature and its uses

The handwritten signature or rubric, also called holographic signature, is used to legally identify a person. It is made up of a series of graphic strokes, also called graphs, which may or may not contain the name of the person it represents.

It is generally done by hand and must have unique characteristics and features to correctly represent the person who has performed it, avoiding fraud or falsification.

The handwritten signature has been used for different applications, although the process of acceptance of the content of a document stands out above all of them. Although the handwritten signature is used on a daily basis to indicate the authorship of, for example, a letter, its main purposes correspond to those of authorisation, consent or approval.

# Digital electronic signature solutions

With the digitisation of processes and the penetration of digital devices in productive activities, the handwritten signature as well as identity verification methods have been digitised. The result of the digitization of the handwritten signature is the electronic signature.

An electronic signature is used to sign digital documents and accept conditions in certain online procedures for legal, banking or representative purposes. On many occasions, especially in industries such as banking and finance or telecommunications, the electronic signature is a mandatory requirement for a large part of the procedures.

Signing electronically in accordance with established standards ensures fraud and risk prevention as well as complying with required AML5 (Anti-Money Laundering) standards and controls. Therefore, the use and types of electronic signature are configured as follows:

  • Simple electronic signature: The set of digital data joined together with others or unequivocally related are used to identify a signer. It has no additional requirements.
  • Advanced electronic signature: This type of signature, in addition to identifying the signer, detects any subsequent changes made to the signed data and in the signature itself. It is exclusively used by the user and holds a protected control.
  • Qualified electronic signature: Also known as a recognised electronic signature, it is based on an official electronic certificate generated through a certified signature creation device. It is similar to the advanced signature, although it must be issued by a certificate authority.

Taking into account the characteristics of the different types of electronic signature, we can see how this signature is safer compared to the traditional way of signing documents. Likewise, it gains versatility since there are different ways to generate identifying data that recognise and legitimise the identity of the signer: from facial or fingerprint recognition to the traditional handwritten graph.

# Creating a handwritten signature for electronic signing

The electronic signature consists of two fundamental elements: the content to be signed and the data representing the signer. This data must be legitimate proof that represents the identity of the person. The use of the handwritten signature as proof of identity verification is perfectly valid to make an electronic signature complying with the key standards.

The creation of this proof and its association to content or document to be signed is simple and only requires a device with a touch screen and the appropriate software. From an ATM or terminal of the company’s network to a smartphone, tablet or similar device both on-site and remotely, the process runs as follows:

  1. The document to be signed is displayed to the user, being able to check it as long as they need.
  2. The user reads the document and clicks the “sign” button.
  3. The user is requested to sign on the screen with their handwritten signature.
  4. The document has been electronically signed with an electronic certificate of a natural person and a qualified time stamp.

Digitised handwritten signature has been carried out with guarantees and through an agile and comfortable process. It is a solution that may be more familiar to many older users than biometric facial recognition, as they are wary of this type of innovative technology.

For this reason, at Signicat, we are committed to providing comprehensive solutions that let the user choose how to verify their identity during the signing process so that they can agree to a contract or approve the contents of a document.
