28 August 2018

The use of signatures is inseparable from our daily lives. How not, signatures have various important functions for all of us such as to prove identity, maintain the integrity of a letter or document, or to make corrections to a letter / document as proof of the approval of the change.

Then, along with the development of technology, signatures also experience development and transformation. The transformation of this signature comes in the form of a digital signature. However, not all digital signatures have the same protective power. What are the differences? How do you choose the right type of digital signature?.

Digisign digital signatures not only have a high-level security system, but are also very practical and easy to use. Digisign can be used anytime and anywhere regardless of your gadget thanks to an integrated platform. The good news? Digisign digital signatures are also FREE for you to have!

Digital signature is divided into 3 types

Based on the technology it uses, here are 3 types of digital signatures that you need to recognize:

1. Simple

A simple digital signature is a digital signature in its simplest form because it is not protected by any encryption method. The most common example is a wet signature scanned by an electronic device and then inserted into a document. Another example of a simple digital signature is the email signature that we often add at the end of the email, and check the terms and conditions box in the software installation process.

This simple digital signature has various disadvantages. This signature is not encrypted so it is unable to show the signer's identity or changes that occur in the document after the document is signed. In addition, simple digital signature categories are very easy to duplicate or fake. Both in terms of security and legality, the use of digital signatures in this type is not recommended.

2. Basic

Digital basic signatures don't have much difference compared to simple digital signatures. The advantages of basic digital signatures from simple digital signatures are only their ability to show changes that occur after the document is signed. However, this signature still cannot guarantee the security of your identity because it cannot refer to a verified identity. Although using the asymmetric cryptography method, basic digital signature service providers do not optimally verify the user's identity. The signing process is also not through 2-factor authentication. As a result, documents signed with digital signatures of this category still do not have legal power and legal consequences.

3. Advanced & Qualified

Digital signature Advanced & Qualified is the safest digital signature and has legal strength equivalent to a wet signature on paper. Advanced and qualified digital level signatures are made with asymmetric cryptography technology and public key infrastructure. Just like a digital signature in a basic category, advanced and qualified digital level signatures are also able to show when, where, and what devices to use during the document signing process. All changes that occur after the document is signed can also be easily known.

What makes this digital signature service provider more special is the process of verifying the identity of the user they are applying. In fact, advanced and qualified digital signature service providers are required to impose a 2-factor authentication before the document can be signed by the user. The authentication method used also varies: from sending one time passwords via SMS, to biometric scanning on mobile phones. It is this extensive verification and authentication process that makes documents signed with digital signatures this category already has an electronic certificate that is uniquely attached to the identity of the signatory.

Choosing Legitimate Digital Signature Services in Indonesia

After learning the 3 types of digital signatures on the market, of course you as a user can already determine for themselves that advanced and qualified digital level signatures are the best choice you have. In Indonesia, certification of advanced and qualified digital level service providers is regulated by the Ministry of Communication and Information.
