There are number of differences between electronic signatures and digital signatures, from the technology and infrastructure used to deploy and the level of security and authentication, to legal frameworks and compliance requirements across and, use cases and industry adoption.

 

 five types of signatures:

Simple Electronic Signatures (SES) – the most basic type of signature and is the least secure type as it doesn’t provide any verification of the signer’s identity.
Electronic Seal (eSeal) – is a digital equivalent of a corporate seal used to verify the integrity and origin of an electronic document. eSeals hold the same weight as an
Advanced Electronic Signatures (AES) – is a type of electronic signature that offers a higher level of security and authentication by using cryptography through a digital certificate issued by a Trust Service Provider.
Qualified Electronic Signatures (QES) – is the most secure form of electronic signature that meets specific legal requirements and is backed by a qualified digital certificate, again issued by a Qualified Trust Service Provider (QTSP).
Qualified eSeals – are verified with a qualified certificate, issued by a QTSP, meaning the owner of the seal has been vetted and verified to provide a strong level of digital trust.
Qualified Trust Seals (QTSeals) - A Type of electronic seal which is generated with a qualified digital certificate. Issued by a QTSP, it provides a quantified level of trust and can be used to sign documents at scale.

Best Practices for Implementing Digital Signatures 
Once you’ve assessed your organization's specific needs and goals, implementing digital signatures effectively requires implementing best practices.

Develop policies and procedures around signature processes, and educate employees.
Prioritize security by selecting a solution that employs robust encryption and authentication.
To maximize efficiency, integrate the solution seamlessly into existing workflows .
Regularly review and update your processes to stay compliant with relevant requirements and regulations.
Provide adequate training and support to ensure smooth adoption and usage across the organization.
