What is an eSignature?

An electronic signature, commonly referred to as an eSignature, is a broad category that encompasses various methods of signing documents electronically rather than using paper and ink. 

It can take the form of a scanned image of a handwritten signature, a typed name, a digital representation of a signature, or a unique identifier such as a PIN or password. These are used to indicate the signer’s intent to agree to the contents of a document or transaction.

An eSignature can take various forms such as: 

  • Typed Names: Simply typing your name into a designated field in a document.
  • “I Agree” Buttons: Clicking buttons on websites that state you agree with the terms or conditions presented.
  • Digital Drawing: Using tools to draw your signature just like you would do on paper but digitally.

eSignatures are recognized legally in many jurisdictions around the world thanks to laws like the U.S. Electronic Signatures in Global and National Commerce Act (ESIGN Act) and the European Union’s Electronic Identification And Trust Services regulation (eIDAS). These legislations have paved the way for wider adoption by providing legal standing similar to traditional signatures under certain conditions.

Potential Security Concerns with eSignatures

While eSignatures offer convenience and efficiency, they may not always carry the same level of security assurance as digital signatures — a more secure subset that uses encryption technologies. 

Some forms of electronic signatures could be easily manipulated or forged if proper verification processes aren’t implemented. 

For instance, typed names or clicked agreements don’t provide evidence about who actually performed these actions without additional authentication measures being taken. Therefore, businesses using this technology, especially for digital contracts, need to ensure that their chosen solution has adequate security features capable of verifying the identity of the user effectively.

Incorporating robust electronic signature solutions like FillFaster can significantly enhance contract management workflows while ensuring compliance with relevant regulations and safeguarding against potential fraud risks associated with less secure methods.

What Is a Digital Signature?

On the other hand, digital signatures are a specific type of electronic signature that offers an added layer of security and authenticity. Digital signatures use cryptographic technology to provide a unique digital fingerprint for both the document and the signer. This ensures the integrity of the document and verifies the identity of the signer.

How Does Digital Signature Work?

Digital signatures operate on the principle of public-key cryptography, establishing a secure and verifiable link between the signer and the document. Here’s how digital signature works:

  • Key Pair Generation: Two mathematically related cryptographic keys are generated for the signer – a private key and a public key. The private key remains solely in the signer’s possession, while the public key is made available to those needing to verify the signature.
  • Hash Function: A unique, fixed-length digest, called a “hash,” is calculated from the document’s contents using a cryptographic hash function. This mathematical algorithm produces a digital fingerprint that is fundamentally tied to that specific version of the document. Even the slightest change to the document’s contents will generate a completely different hash.
  • Signature Creation: The signer’s private key is used to encrypt the hash value, resulting in the digital signature. This signature is then appended to the document being signed. 
  • Signature Verification: To verify the signature, the recipient utilizes the signer’s public key to decrypt it. They concurrently generate a new hash value from the received document. If the decrypted hash and the newly calculated hash match exactly, it confirms two crucial points: (1) The document is authentically signed by the holder of the private key, and (2) The document has not undergone any alterations since the moment of signing.

Cryptographic Keys: The Foundation of Trust

Central to this system are two types of keys used in cryptography: public and private keys. 

Public keys, as their name suggests, can be shared openly without compromising security because they’re used solely for verifying signatures – not creating them. 

Private keys must remain confidential since they’re used to create your signature; revealing it would allow others to forge your signature on documents.

Elevating Document Security with Identity Verification

Apart from preventing unauthorized changes to signed documents, digital signatures also serve another crucial role: validating identities online securely. 

Through digital certificates issued by trusted Certificate Authorities (CAs), each signature gets linked back uniquely to its signer – assuring who exactly has signed off on any given contract or agreement within platforms.

Benefits of Digital Signatures

These advanced electronic signatures offer a secure and efficient way to sign documents electronically, providing several key advantages over traditional e-signatures.

1. Security

Digital signatures come with enhanced security features that safeguard against fraud and unauthorized access. By utilizing encryption technology, digital signatures ensure that the document content remains confidential between the signing parties. This level of security is paramount for small to medium-sized business owners who rely on digital contracts for their services.

2. Authenticity

The authentication process behind a digital signature verifies the signer’s identity using their unique personal identification details, such as PIN or biometric data. This ensures that each party involved in the transaction can trust the legitimacy of both the document and its signatories. The rigorous verification process adds an extra layer of assurance for all parties involved.

3. Non-repudiation

A digitally signed document cannot easily be denied by its signer once it has been executed. Non-repudiation prevents any party from disputing their involvement or agreement after the fact, making these types of signatures incredibly reliable in binding agreements.

This feature is particularly beneficial when dealing with high-stake contracts or sensitive information requiring indisputable proof of participation and consent.

3. Integrity

Digital signatures also guarantee that a document has not been altered after being signed. Any modification made post-signature invalidates it immediately – ensuring complete transparency and integrity throughout its lifecycle. For businesses operating online, this means peace of mind knowing your documents remain untampered from point A to B.

4. Legal Admissibility

In many jurisdictions around the world, digital signatures hold up in court similarly to handwritten ones due to legislation like the Electronic Signatures in Global and National Commerce Act (ESIGN). Their legal admissibility provides an added advantage by streamlining dispute resolution processes should issues arise during contract enforcement phases – offering yet another reason why transitioning to digital signature solutions like FillFaster and DocuSign can be highly advantageous for modern businesses looking toward future-proofing their operations.

Key Differences: e-Signature vs Digital Signature

As the digital landscape evolves, small to medium-sized businesses are increasingly leveraging technology for contracts and agreements. Understanding the difference between an electronic signature (eSignature) and a digital signature is crucial for ensuring compliance, security, and efficiency in your business operations. 

Here’s a breakdown of their key differences.

Featuree-SignaturesDigital Signatures
Legal ImplicationsVarying levels of enforceabilityGenerally recognized as legally binding, especially with certificates issued by trusted authorities
SecurityBasic to moderate, depending on the methodHigh security using cryptography, encryption, and tamper-proofing
AuthenticationSimple (usernames, passwords, etc.)Advanced (Public Key Infrastructure (PKI), digital certificates)
Use CasesWide range (contracts, forms, agreements)Sensitive documents, high-value transactions, regulated industries
Industry RegulationsMay vary by industry and regionOften subject to specific legal and compliance frameworks

Legal Implications and Security Features

One of the key differences between e-signatures and digital signatures lies in their legal implications and security features.

Digital signatures use cryptographic techniques to ensure the authenticity and integrity of the signed document, providing a higher level of assurance compared to standard e-signatures.

Authentication Methods

Another important distinction is the authentication methods used in e-signatures and digital signatures. E-signatures may rely on simple authentication methods such as a username and password, whereas digital signatures use more advanced methods such as Public Key Infrastructure (PKI) to verify the identity of the person signing. This difference in authentication methods contributes to the higher level of security provided by digital signatures.

Use Cases and Industry Regulations

The use cases and industry regulations surrounding e-signatures and digital signatures also differ. 

  • E-signatures are commonly used for a wide range of documents, including sales contracts, HR forms, and customer agreements. 
  • Digital signatures are often required for highly sensitive documents, such as legal contracts, financial transactions, and government records. Additionally, certain industries and regions may have specific regulations regarding the use of digital signatures for compliance and legal purposes.

Both are legally solid, but if you’re dealing with sensitive info or need extra authentication, go for the digital signature.

💡 E-signatures are the quick and easy way to sign off on everyday documents, while digital signatures come with heavy security when it matters.
