What is an Electronic Signature?
An electronic signature is a digital representation of an individual's intent to sign a document or agreement. These signatures can take various forms, including scanned images of handwritten signatures, typed names, or even recorded voices.
More loosely, e-signatures are used to refer to any signature that's applied electronically as opposed to on a physical piece of paper. An electronic signature does not confirm the content within a document, nor does it provide security and assurance and not all electronic signatures’ assurance levels are the same in the eyes of the law. If you're in an industry that is highly regulated where you deal with personal and/or private information and data – finance or accounting, HR, legal, or healthcare, to name a few – then you might need to consider a more secure option.
What are the Different Types of Electronic Signatures?
There are 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 Signature.
- 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.
What is a Digital Signature?
A digital signature is a type of electronic signature that uses cryptographic technology to create a digital certificate, to provide proof of an identity. By creating a unique digital fingerprint, digital signatures provide the highest level of security assurance by verifying the signer’s identity. This is done through a trusted third party, known as a Certificate Authority (CA).
Advanced Electronic Signatures (AES) and Qualified Electronic Signatures (QES) are digital signatures, as they are backed with cryptography and provide security assurance of varying levels.
Digital signatures assure that:
- The document is authentic and comes from a verified source.
- Identities have been verified by a publicly trusted organization (the CA).
- The document has not been tampered with since being digitally signed as the signature would be displayed as invalid if changes were made.
Are Digital Signatures Legal?
Yes, digital signatures are recognized as legally binding. But it is important to note that the different types of signatures hold a different weighting. For example, a Qualified Electronic Signature (QES) cannot be disputed or be denied admissibility as evidence as it is uniquely tied with the signer’s identity.
Various laws and regulations, such as the Electronic Signatures in Global and National Commerce (ESIGN) Act in the United States and the eIDAS Regulation in the European Union, provide a legal framework for the use and acceptance of digital signatures. It is important to familiarize yourself with the specific laws and regulations in your jurisdiction to ensure compliance and legal validity.
What's the Difference Between Electronic Signatures and Digital Signatures?
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.
Electronic signatures encompass a broad range of methods for signing documents, whereas digital signatures additionally offer advanced security and authentication measures through cryptographic technology.
Let’s understand the key differences in more detail:
- Technology and Infrastructure: Electronic signatures can be applied with a range of methods, including scanned images of handwritten signatures, typed names, or recorded voices. Digital signatures, on the other hand, create a unique digital fingerprint of the document using cryptographic technology, providing enhanced security and integrity.
- Level of Security and Authentication: Digital signatures provide a higher level of security compared to electronic signatures. Electronic signatures do not provide security, assurance or confirmation of the content within a document.
- Legal Frameworks and Compliance Requirements: Digital signatures require the use of a certificate issued by a Qualified Trust Services Provider to establish the identity of the signer. A QTSP provides the verification of the signer’s identity and must comply within the regulations, such as eIDAS. On the other hand, electronic signatures may not meet the legal requirements and acceptance can vary.
- Use Cases and Industry Adoption: Documents which have been signed electronically in the simplest form, has increased over the years and across several industries. Digital signatures however, due to their enhanced security and legal validity, are typically preferred in situations where there is a need for higher levels of integrity and non-repudiation, such as in financial transactions, legal documents, or sensitive agreements.
Benefits of Digital Signatures
There are number of benefits of using digital signatures, including:
- Cost and Time-saving Advantages: Digital signatures streamline the signing process as documents can be signed and shared instantly, saving time and reducing delays in transactions.
- Enhanced Security: By using digital signatures and the cryptographic elements, a signed document can retain its integrity and authenticity and provide a high level of security, and reduces the risk of fraud and tampering.
- Cost Savings and Environmental Sustainability: The need for printing, paper, ink and postage is eliminated saving on cost associated with physical documentation whilst also contributing to environmental sustainability.
- Improved User Experience: Digital signatures can enhance the experience by offering the flexibility to sign documents from anywhere, at any time, using any device with an internet connection.

Adding a certifying signature to a PDF means you are the author of the document, have finalized its contents and want to secure it against tampering after it has been distributed.
Certified documents display a blue ribbon across the top of the document containing the signer's name and the Certificate issuer - a clear, visual indicator of document authenticity and authorship.
- Approval Signatures
Approval signatures expedite an organization's approval procedure by capturing the electronic approvals made by individuals or departments and embedding them within the actual PDF.
Signatures can be customized to include an image (e.g., your physical signature or official seal) and various signature details (e.g., signing location, date, reason for signing).
Microsoft Word
Microsoft also supports two types of Digital Signatures using a token certificate - visible and non-visible.
- Visible Digital Signature
This appears as a signature line, like a physical document. This method is commonly used when you need multiple users to sign documents like contracts or other agreements.
- Invisible signature
An invisible signature is used when you need to provide document authenticity, integrity and origin assurances, but don’t need a visible signature line. Documents with a non-visible signature display a blue ribbon in their task bar.
