Don't know what to choose between electronic signature and digital signature? In this article we offer you everything you need to know.
Digital transformation has driven the adoption of electronic methods to authenticate documents and transactions. In this context, terms such as digital signature and electronic signature are often used interchangeably, although they have significant differences. This article explores these differences and how to create each type of signature.
What is an electronic signature?
An electronic signature is a broad term that encompasses any digital mark, symbol, image, or process used to indicate consent or approval on a document or transaction.
According to Entrust, “An electronic signature can be an image of a signature, a drawing, a click on a button, or any symbol that verifies a document. However, it does not always guarantee the identity of the signer or the authenticity of the document.”
In short, an electronic signature:
- Is legally binding in many contexts.
- Can take simple forms such as a scanned handwritten name or a click of acceptance on a form.
- It is generally not supported by advanced technology such as encryption.
Advantages of electronic signature
Ease of use: It is easy to implement and use, ideal for commercial contracts or simple agreements.
Time saving: It allows you to sign documents quickly without the need for physical processes.
Versatility: It is suitable for various sectors, from employment agreements to online acceptance forms.
What is a digital signature?
A digital signature is an advanced type of electronic signature that uses Public Key Infrastructure (PKI) technology to ensure the authenticity, integrity and origin of a document. As Entrust notes, “A digital signature is an electronic fingerprint backed by digital certificates containing verified details of the signer’s identity.”
The digital signature:
- Provides high levels of security by using encryption.
- Guarantees the identity of the signer using certificates issued by Certification Authorities (CAs).
- It is used on documents where authenticity and confidentiality are crucial, such as financial data or medical records.
Key features of digital signatures
Authenticity: Verifies the identity of the signer in a reliable manner.
Integrity: Ensures that the document has not been altered after being signed.
Non-repudiation: Prevents the signer from denying having signed the document.
Key differences between digital signature and electronic signature
Here are the main differences according to Geeks for Geeks:
How to create a digital signature?
Creating a digital signature involves using tools backed by PKI technology. Here are the basic steps:
Acquire a digital certificate:
- Request it from a trusted Certificate Authority such as Entrust or GlobalSign.
Set up the software:
- Use programs such as Adobe Acrobat, Microsoft Word or specialized document management solutions.
Digital sign a document:
- Upload the document to the chosen platform.
- Select the option to digitally sign and verify your identity with the certificate.
Validate the signature:
- The software will confirm the authenticity and integrity of the signed document.
How to create an electronic signature?
Unlike digital signatures, electronic signatures are simpler to create:
Scan a written signature:
- Write your signature on paper, scan it, and save it as an image.
Use online tools:
- Platforms like DocuSign or HelloSign allow you to draw or upload a signature.
Insert into documents:
- Add the image or symbol of your signature to documents in PDF, Word, or other formats.
Although it is a more accessible process, it is important to consider that the electronic signature does not offer the security levels of the digital signature.
Which one to choose?
The choice between a digital signature and an electronic signature depends on specific needs:
Electronic signature:
- Ideal for business agreements, acceptance forms, or simple internal processes.
- Easy to implement in applications where security is not the primary concern.
Digital signature:
- Recommended for legal contracts, financial data, or documents requiring strict validation.
- Guarantees authenticity, confidentiality, and integrity.
Both electronic signatures and digital signatures are valuable tools in the digital age, but they should not be confused. While the electronic signature is simpler and more accessible, the digital signature offers a higher level of security and authenticity.
By understanding these differences and knowing how to create each type of signature, companies and users can choose the most suitable solution for their needs, optimizing their processes and ensuring trust in their digital transactions.
