Hasn’t this question crossed our minds at least once?   

We have known the concept of and use of signatures since our childhoods without even acknowledging its importance.    

So, this brings us to the first question, why are signatures used?  

Well, for centuries, signatures have been used to authenticate someone’s identity and consent. They are considered as someone’s agreement or consent for maybe, a sales agreement, employment contract, or one’s identity.   

But, in the last decade, the world became increasingly delocalized. This meant that the contracts were not always happening in the here and now with all the parties present.    

In the 20th century, fax machines an efficient method of sending documents, with legally enforceable signatures, became popular. Traditionally, documents were printed, then signed, and then scanned to the computer for storage.  

This process was not only tedious and frustrating but also leads to wastage of paper and other resources. This birthed the idea of electronic documents and digital signatures.  

Q1. What is Digital Signature?  

To think, a digital signature is a digital equivalent of a handwritten signature, is an understatement.   

Instead, a digital signature is a mathematical technique used to validate the authenticity and integrity of a digital document.   

You might think that this method is fairly new but individuals and businesses started to adopt it widely in the late 2000s.   Paperless Digital Signature

Q3. What are the Types of Digital Signatures?  

Based on the technology it uses, all the digital signatures fall into these three types:  

1. A simple Digital Signature: is the simplest form of the digital signature because it is not protected by any encryption method. For example, a simple digital signature that we often add at the end of the email.  

As this signature is not encrypted, it does not show the signer’s identity or changes that occur after the document is signed.    

2. Basic Digital Signature ability to show changes that occur after the document is signed. But, this type of signature still does not guarantee security.   

The documents signed with both simple and basic types of digital signatures do not have the legal power and legal consequences.  

3. Advanced Digital Signature is the safest and has the legal strength equivalent to a wet signature. Advanced signatures can show when, where, and what devices are used during the document signing process.

But, the three most crucial benefits of a digital signature are:    


Digital Signature offers efficiency as documents can be signed at any time, from anywhere in the world.   


The owner of the digital signature also has a digital key and is bound to a specific user. Hence, there is no need for a handwriting expert anymore.

Well, for one, the information exchanged over the internet is facing more security issues than ever before. For instance, Security Magazine says that there are over 2,200 attacks each day which breaks down to nearly 1 cyberattack every 39 seconds.  

A digital signature is a great way to curb or mitigate these kinds of attacks. For instance, a malicious email is sent in a phishing attack that appears to be from someone different than the person who sent it.  

Let’s understand it this way, you receive an email from the CEO. It contains a directive that guides you to click on a certain link and fill in the required details.   

A few hours later you are informed about the breach in security and the bread crumbs ultimately lead the security team to your computer.  

The security team tells you that the email you clicked on and the link you followed was from the hacker pretending to be the CEO.
