Since the ESIGN Act (Electronic Signatures in Global and National Commerce Act) was passed in 2000, electronic signature adoption has been on the rise among businesses worldwide. In fact, 65% of businesses are expected to replace their paper-based processes by the end of this year.
With the DTM (Digital Transaction Management) industry poised to grow into a $30 billion market by 2020, electronic signatures are likely to achieve mainstream adoption on a similar timeline. However, consumer awareness in the electronic signature space is limited in a number of ways. For example, the terms ‘electronic signature’ and ‘digital signature’ are often used interchangeably.
To set the record straight once and for all, this blog post will highlight the important differences between these two types of signatures.
What is an electronic signature?
According to the ESIGN Act, electronic signatures (or e-signatures) are an “electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.”
In other words, an e-signature is a digitized version of your handwritten signature. It can be used to indicate the intent to approve or accept the contents of a document.
What makes electronic signatures popular?
E-signatures’ greatest advantage is that they are easy to use. They allow users to sign documents online with the click of a mouse, or trace their handwritten signature using a finger or a stylus.
What is a digital signature?
A digital signature refers to a category of electronic signature that leverages algorithms to generate a unique digital fingerprint (AKA a hash) that is unique to each document. This hash can be linked to the signer’s identity.
How do digital signatures work?
Digital signatures are usually created using the Public Key Infrastructure (PKI) system. These signature softwares leverage an algorithm to generate two keys (a sequence of numbers) – a private key and a public key, which are mathematically linked.
When a user signs a document online, he/she leverages the private key to create a signature. The private key remains solely under the owner’s control.
During the signing process, a crypto code ID is created and embedded into the document. At the time of verification, the signer simply uses his/her public key to unwrap the digital signature code and compare it with the document to ensure a match.
What makes digital signatures popular?
Digital signatures leverage cryptography to provide proof of the integrity and origin of each signature, thus providing for non-repudiation.
