Types of E-Signatures

There are three leading classifications of electronic signatures such as simple, advanced, and qualified. Let’s comprehend them in a bit more detail.

1. Simple Electronic Signatures (SES)

This is the most simple yet amazing type of eSignaure. Generally, they don’t need identity verification and are used for documents with low liability threats. 

Since these signatures have minimum legal weight when compared with advanced and qualified electronic signatures, they are usually used to sign various documents like information letters, internal documents, and others.

2. Advanced Electronic Signatures (AES)

The Advanced Electronic Signatures (AES) mandate an elevated tier of user authentication. The main purpose of AES is to recognize the signatory and ensure that there are no subsequent alterations in the data. 

Nevertheless, AES requires certification from a Certificate Authority and typically counts on public-key infrastructure (PKI) technology with the help of cryptographic keys and certificates. Documents that utilize the AES e-signature solution are Mortgage documents, non-disclosure agreement forms, rental agreements, and others.

3. Qualified Electronic Signatures (QES)

QES or Qualified Electonic Signatures are regarded as identical as to handwritten signatures. This implies not only the act that they are leveraged for signing the documents with high liability threat but also that they fulfill the stringent needs for authentication.

However, there are some documents that use the QES e-signature solution like bank loans, audit reports, consumer credit contracts, and others.

How Does E Signature Work?

An e-signature works by leveraging cryptographic approaches to establish the signer’s originality and guarantee the signed document’s probity. Firstly, the signer makes a digital replica of their signature with the assistance of a private key that is unusual to them.

This private key renders a digital signature as per the document. After this, recipients can ascertain the genuineness of the signature with the assistance of the signer’s general key that is associated with their individuality.

The validation approach ensures that the document has not been altered or changed since it was first signed. Digital signatures deliver a tamper-evident and protected approach to electronically signing documents in order to secure trust and integrity in digital marketing.
