Electronic Signature vs Digital Signature – WeSignature

Do you use a digital signature when you sign a document online?

Is it possible to have an electronic one?

Is there a difference at all?

There is, indeed.

A very common question that gets asked while discussing the topic of electronic signatures is; What is the difference between digital signature vs electronic signature?

A very direct and generic answer to this question is that electronic signature vs digital signature is used interchangeably, but the fact of the matter is that these two are quite different.

A significant difference between digital signature versus electronic signature is that digital signatures are mostly utilized to secure documents because they guarantee the authenticity of documents while online electronic signatures are like symbols attached with a contract where the signer has a very clear intent to sign documents.

We’ll go over the difference between digital and electronic signature so you’ll know what to look for if you’re thinking about switching to a paperless, digital platform.

What is Electronic Signature?

Electronic signatures are like an electronic process, or a symbol attached or logically associated with a contract or any other document. E-signatures are executed to perform online document signing by a person who has a clear intent to sign the document for different purposes.

In other words, an e-signature is more like a digital version of a handwritten signature. They are used to showcase the intent to either approve or accept the contents of important documents by either a person or different parties involved.

One of the most relevant and significant benefits of electronic signatures is that they make signing online documents remarkably simple. They enable the users to create an electronic signature in word with either a tap or just a click of the mouse allowing them to sign using their fingers or a stylus.

What is Digital Signature?

Digital signatures are one of the categories of electronic signatures that leverage algorithms to produce a unique digital fingerprint for each document. This digital fingerprint is linked to the signer’s identity and is used to authenticate it.

Fundamentally, one can create digital signatures utilizing the public key infrastructure system. The signature software uses an algorithm to produce two keys (a public and a private key) consisting of a sequence of numbers that are essentially linked to each other mathematically.

When any user signs an online document, he/she uses the private key to create a suitable signature. The private key is basically used to stay under the owner’s control essentially. At the time of the signing process, a crypto code ID is created and embedded inside the document.

When verification is facilitated, the signer simply utilizes his/her public key for unwrapping the digital signature code while subsequently comparing it with the document to ensure that there is a match.

A digital signature uses cryptography to provide authentic proof of the integrity and origin of every signature while verifying it.

What is a Digital Certificate?

Public Key Infrastructure (PKI) and the use of public and private keys are the foundation of digital signatures, which assure the safety of digital transactions. You need to know that all parties involved in an electronic signature transaction are utilizing valid keys.

At this point, the digital certificate becomes useful. An electronic document called a digital certificate is issued by a Certificate Authority (CA) or Trust Service Provider (TSP) to authenticate a signer’s identity and associate the signer’s public key with their name. Best-in-class eSignature systems integrate digital certificates in the e-sign process to authenticate the signer because the legal definition of an electronic signature always contains language around signer ownership.

Since the certificate contains data about the signer’s identity, it is used to verify and attest that a certain electronic signature belongs to a particular individual (e.g., name, ID number, signature keys, certificate issuer, etc.). In order to create a digital signature, certificates are frequently saved on the devices used to make those signatures, such as secure smart cards, tokens, and a hardware security module (HSM) in the cloud. The signer’s certificate is cryptographically linked to the document using the signer’s private key during the signing process.

Types of Digital Certificates

Organisational needs for digital certificates and how they are managed might vary widely depending on factors including location, industry, and the level of risk associated with a given transaction. It’s important to note that the location of the certificates is independent of the method chosen for signing.

Server-Signing Certificate: Digital signatures are stored in the cloud, where a trusted certificate is used to verify the signer’s identity and the authenticity of the document.

Local-Signing Certificate: It is the signer’s personal certificate stored locally on a PIN-protected smart card, USB token, or computer that verifies the signer’s identity and is used to digitally sign the document.

Key Differences Between Digital Signature Vs Electronic Signature

Electronic Signature

  • Electronic signatures online are mainly used to verify the documents.
  • An electronic signature is not regulated by the certification authorities.
  • eSign uses a wide range of methods for the purpose of authenticating the signer’s identity such as enterprise ID, emails, phone verification, etc.
  • Electronic signatures use an audit trail to showcase the proof of signing a document.
  • eSign is concerned with a comparatively lesser number of security features when compared to digital signatures.

Digital Signature

  • Digital signatures are mainly used to secure a document.
  • On the other hand, digital signatures are most commonly regulated by certification authorities.
  • Digital signatures use the certificate-based ID for the purpose of authenticating the signer’s identity.
  • Digital signatures bind each signature to the document through encryption to showcase the proof of signing.
  • Digital signatures are specifically concerned with an increasing number of security features.

The Main Differences Between Digital Signature and Electronic Signature

  • The main difference is that, while a digital signature refers to a set of cryptographic methods, the concept of an electronic signature is fundamentally legal in nature, as it provides the signature with a regulatory framework that grants it legal validity.
  • Another distinction is the context in which they are employed. An electronic signature is mostly used to sign electronic documents where the signatory intends to use his e-signature to sign the document. A digital signature, on the other hand, is used to safeguard papers and is utilized by certification bodies.
  • Electronic signatures serve as proof that the signee has accepted the conditions of a contract via electronic means. This may include things like typing their name into an email, entering a PIN into an ATM, signing their name electronically on a touch screen gadget, or checking a box to sign up for a new streaming subscription.
  • The basic goal of digital signatures is to secure a document so that it cannot be altered without permission. An electronic signature, on the other hand, is primarily used to verify a document.
  • The verification process of the digital signature is performed by a trusted service provider or a trusted certification authority. There is no verification process for creating online signatures.

Conclusion – Difference Between Digital Signature and Electronic Signature

Digital signatures and electronic signatures are primarily used to sign documents online. When comparing the two, it is possible to conclude that electronic signatures are superior to digital signatures.

FAQ – Digital vs Electronic Signature

1. Does the Law Accept Digital Signature and Electronic Signature?

Both digital signature and electronic signature are legally binding where U.S. federal rule applicable, according to the federal ESIGN Act. In many cases where ESIGN fails to apply, UETA is a suitable alternative. The Uniform Electronic Transaction Act (UETA) was first introduced in 1999 and has essentially the same terms as ESIGN.

When both parties agree to move forward with a document signed electronically, the electronic signature is legally equivalent to a handwritten signature under both acts. UETA rules were adopted by Washington, D.C., the U.S. Virgin Islands and 47 states. Both ESIGN and UETA are electronic signature laws which is governed by US.

2. Do Electronic Signature and Digital Signature use Cryptographic Algorithms?

If we compare digital signature versus electronic signature, both have a lot of differences.

A digital signature has been created under cryptographic algorithms whereas electronic signatures are less secure. Cryptographic algorithms are not used in electronic signature.

3. When to Use a Digital vs Electronic Signature?

In many situations, a basic electronic signature is acceptable if you have been sent a document in PDF or Word format for signing. Talk to an expert if you’re unsure about the type of signature that’s needed.

Consider the significance of the document and the potential for legal objections to the signature before deciding whether to use an electronic signature vs digital signature. Certain types of documents require digital signatures in particular industries and countries, while others may need to be signed in wet ink or sealed with a notary.

4. What is the Difference Between an Advanced Electronic Signature and a Digital Signature?

Advanced electronic signatures (AES) and digital signatures are two types of electronic signatures used to sign documents and transactions electronically. AES is a more secure and trustworthy type of electronic signature that meets specific legal requirements set by eIDAS, the European Union’s regulation on electronic identification and trust services. 

In contrast, digital signatures use mathematical algorithms to create a unique digital fingerprint of the signed data, providing a high level of integrity and authenticity. Both types of electronic signatures offer a convenient and secure alternative to physical signatures and play an important role in modern business and legal practices.

5. Are Electronic Signature and Digital Signatures Better?

The choice between electronic and digital signatures depends on the specific needs and requirements of the user. Advanced electronic signatures (AES) have specific legal requirements set by eIDAS, providing a higher level of security and trustworthiness compared to other types of electronic signatures. 

Digital signatures use mathematical algorithms to create a unique digital fingerprint of the signed data, which provides a high level of integrity and authenticity. The choice will depend on factors such as the level of security and legal recognition required, the technical capabilities of the signing system, and the user’s personal preferences. 

Ultimately, both electronic and digital signatures provide a secure and convenient alternative to physical signatures.

6. Which is More Secure Between an Electronic Signature vs Digital Signature?

When it comes to security, digital signatures are generally considered to be more secure than electronic signatures. 

Digital signatures use cryptographic algorithms to create a unique digital fingerprint of the signed data, which is then encrypted with a private key. This process ensures that the integrity and authenticity of the signed data cannot be tampered with or altered without invalidating the signature. 

The use of encryption and public key infrastructure (PKI) provides a high level of security and protection against fraud and forgery. 

In contrast, electronic signatures can include a range of different technologies and processes that do not necessarily provide the same level of security as digital signatures. 

While advanced electronic signatures (AES) meet specific legal requirements set by eIDAS, they do not necessarily use the same level of encryption and PKI as digital signatures. 

Overall, while both electronic signatures and digital signatures provide a secure way to sign documents on iPhone, Android devices and transactions electronically, digital signatures are generally considered to be more secure due to their use of encryption and PKI.
