The Oxford dictionary defines e-signatures (or electronic signatures) as “A person’s name written in a distinctive way as a form of identification in authorizing a cheque or document or concluding a letter.”

Paper-based documents in the past required what is now termed as a “wet” signature, or a hand -written name. More formal documents or contracts/agreements required witnesses to the signature, and an initial on each page, for both the signatory and the witnesses.

This process can be cumbersome, and time consuming. As a result, contracts or agreements often went unsigned, and even signed agreements ran the risk of being challenged in Court. Was the signatory authorised to sign? Is it the original documentation? Does the signature match the identity of the person signing? And documents that have been tampered with, are some examples.

Electronic signatures (or e-signatures) are the most secure and tamper-proof way of signing documents. In most countries these are permitted through legislation, defining what constitutes a digital signature.

There Are Typically Four Forms of Electronic Signature

  1. A click wrap or text box where a user ticks somewhere in an electronic form that they accept the terms and conditions.
  2. An electronic signature, an example would be a digital image of a person’s handwritten signature.
  3. A digital signature, which is a level higher in security than an electronic signature, that ensures the authentication, date and time stamped, and tamper proofed documentation.
  4. An advanced digital signature, which is authenticated and certified by a legislated body, and required in a few very specific type of agreements.

Electronic signatures require software for their generation, and can look quite different from a traditional signature, in some cases for familiarity they can include a record of the electronic signature. Examples are provided below.

The concept of an e-signature goes back as far as 1976, although later refined standards emerged in 1984. Now millions of documents are signed globally using e-signatures, as the concepts become widely adopted.

A Digital Signature

There are Four Major Benefits of Electronic Signatures:

  1. Efficiency: documents can be signed in an instant from anywhere in the World where there is an internet connection. All pages can be automatically initialled, and there is no need for witnesses. It’s customer friendly, allows for contracts to be signed sooner, booking revenue sooner.
  2. Authentication: the owner of the digital key is bound to a specific user, no need for a handwriting expert anymore.
  3. Integrity: the document and the signatory are linked, so that there can be no changes to the document post signature.
  4. Non-repudiation: an entity that signed digitally cannot deny that they have signed.

It’s not only the financial benefits that accrue, the case for digital signatures is made from a governance and risk perspective as well. If combined with a contract management application, the entire process is simplified and automated from origination through to signing, storing, audit trails and management.
