Electronic signatures are already widely used to sign business and legal documents today. However, electronic signatures are still as prone to forgery and manipulation as wet signatures. That’s why you need to check the validity of electronic signatures on digital documents.

The question is, how do we check the authenticity of electronic signatures so that the electronic documents we sign are legitimate? Find out the answer in this article!

What is an Electronic Signature?

As the name implies, an electronic signature is a signature created electronically through a particular system or application and used to identify its owner on an electronic document.

In today’s digital era, electronic signatures are an efficient solution to streamline business processes. Electronic signatures already represent approval or authorization on electronic documents so you and your partners don’t need to be physically present.

Electronic signatures include a variety of methods, including the use of special encryption codes and other authentication methods that secure the signature process in cyberspace.

It is important to note that e-signatures have expanded their use to various sectors, ranging from large corporations to small businesses.

The utilization of electronic signatures not only speeds up the transaction and agreement process but also reduces dependence on physical documents. This is in line with the digital transformation that is happening in various industries where efficiency and speed are the keys to success.

how digital signatures work

Based on the level of security, there are three types of electronic signatures:

1. Simple

Simple electronic signatures are usually used on documents that do not require a strict identification process or the information contained in them is not too sensitive.

The process of creating a simple signature often only involves using methods such as entering a name or manual signature through a touchscreen device. Although low-level, the validity of this electronic signature is still guaranteed through the use of encryption technology so that it is difficult to fake.

2. Basic

This electronic signature offers a higher level of security compared to the simple signature. The process involves more sophisticated identity verification steps, such as authentication codes or digital signatures that require additional confirmation.

This type of signature is often used for documents that require a medium level of security, such as business contracts or legal agreements.

3. Advanced and Qualified

Advanced electronic signatures signify the highest level of security. The use of advanced technologies such as public key encryption or digital certificates makes these signatures difficult to forge.

This type of signature is generally used for documents that are legal or require a high level of security, such as notarized documents or important contracts.

Risks Posed by Fake Electronic Signatures

While electronic signatures bring many benefits, we should not overlook the potential risks that may occur, especially those related to forged signatures.

Some types of signature forgery include manual replication by unauthorized parties or forgery using certain technologies to make fake signatures difficult to detect visually. This risk becomes even more serious when forged electronic signatures are found on legal or financial documents.

The potential risks of forged signatures involve financial loss, loss of trust, and even legal issues. Irresponsible parties can take advantage of the inability to verify the authenticity of electronic signatures.

Therefore, it is important to understand and implement proper security measures in the use of electronic signatures to protect the integrity of documents and the information contained therein.

How to Verify Validity

You need technological assistance to check the validity of electronic signatures.

Many applications can be used to check the authenticity of electronic signatures, ranging from Microsoft Word to the website provided by the Ministry of Communications and Informatics (Kemkominfo). Here are some steps to verify the authenticity of electronic signatures on each tool.

1. Adobe Reader

First, you can use Adobe Reader if the electronically signed document has a PDF format. The steps are as follows:

  • Open Adobe Reader, then open the file you want to check the authenticity of the electronic signature.
  • Select ‘Signature Properties’ in the menu.
  • Adobe Reader will display information about the electronic signature contained in the document. For example, the time of signing, the identity of the electronic Signature owner, and other details. If the signature is fake, this information will not be visible.

2. Microsoft Word

If the signed file is in .docx format, then you need to use Microsoft Word to check the validity of the electronic signature. Here are the steps:

  • Open the file you want to check the authenticity of the signature in Microsoft Word.
  • Go to the ‘File’ menu, then select ‘Info’ and click the ‘Show Signature’ option.

3. Ministry of Communications and Informatics (Kemkominfo) Website

The Ministry of Communications and Informatics (Kemkominfo) launched a website that is useful for checking the authenticity of electronic signatures. However, the files checked can only be in PDF format. To check the authenticity of an electronic signature on a file, follow the steps below:
