2. What's the difference between a digital signature and an electronic signature?

Digital and electronic signatures are types of signatures that are quite confusing to many people. In fact, scores of people use them interchangeably, thinking they are the same thing. However, the two types of signatures are not the same and differ in several aspects. Understanding the differences between these two signatures will help you understand where and when to use them. Some of the major differences between digital and electronic signatures are:

  • A digital signature combines cryptographic keys for document and user identification, while an electronic signature is an image or drawing appended electronically/digitally on a document.
  • A digital signature is primarily used to protect a document, while an electronic signature is majorly used for document verification.
  • A digital signature can be verified because it contains signer details and the authorizing company/party. On the other hand, an electronic signature cannot be verified because it does not carry the information of the respective parties. It is simply a character/image.
  • A digital signature is regulated by a certification authority, while an electronic signature is not regulated.
  • A digital signature is highly secure, while an electronic signature is vulnerable to compromise.
  • A digital signature has more security features compared to an electronic signature.
  • Digital signatures have encryption standards, while electronic signatures do not involve coding or standards.
  • Digital signatures are used in applications that require verification of the signer's identity, especially when handling sensitive data, paperwork, and contracts. On the other hand, electronic signatures are useful in contracts and agreements.
