How check the signature correctly

Why is it advisable to check the signature on important documents? You just received a document that it signed electronically and you may ask yourself: Is this a real signature? Has this been forged?

There are several ways to verify the authenticity of an electronic signature. Here’s how to do it.

Methods to check the signature of an electronic document

E-signature technology like Viafirma offers multiple options to verify the signatory’s identity before they can access the document and sign, including:

  • Email address: signers enter their own email address, which is compared to the email address used in the invitation
  • Phone number: signers must enter their phone number to continue with the process
  • OTP SMS access code: signers must enter a one-time passcode sent via SMS text message
  • Video-based onboarding validation: signers are requested to prove their identity through a video selfie and a picture of their ID document

Besides, any signed document with Viafirma will contain an audit trail file with all the above information from the signing process, ensuring information integrity at all times, avoiding any kind of manipulation. Therefore, this document serves as valid legal evidence in any court of law.

Why should any company adopt eSignatures

Mobile solutions are on the rise as we are immersed in a digital age. E-signing let their users validate documents within seconds. It’s an increasingly used tool as its benefits in efficiency and closing contracts on-the-go are interesting for businesses.

While many think ther are still security issues, eSignatures go under the principles of integrity, non-repudiation, authenticity and confidentiality. They are your best ally to carry out any telematic procedure with total legal guaranteees.

They are now widely used in private affairs, legal dealings, business transactions, and even as part of official government documents

What should we analyze when we check the signature? 

To check the signature of any electronic document, we must take a deep dive into the definition from Regulation 910/2014/EC on electronic identification and trusted services, known as eIDAS.

There are three types of electronic signatures:

  • Simple e-signature: data in electronic form attached to or logically associated with other data in electronic form and which is used by the signatory to sign. It has legal effect and might hold up in a court of law, though they are easy to forge and cannot uniquely identify the signer.
  • Advanced electronic signature: It is uniquely linked to the signatory. Allows to uniquely identify the signer. Created using signature creation data that only the signatory can use, with a high level of confidence, under his exclusive control and linked to the data signed by him so that any possible further changes are detected. This type of signature certifies the identity of the signatory, integrity of data, providing more legal guarantees.
  • Qualified Electronic Signature: means an advanced electronic signature that is created by a qualified electronic signature creation device, and which is based on a qualified certificate for electronic signatures

The qualified signature provides the highest level of admissibility in EU courts and has the equivalent legal effect of a handwritten signature but it is not the most practical and operational signature. The advanced signature also provides high levels of security and legality; providing full legal support to the process while maintaining ease of use during the signing process and offering an excellent user experience.

Make sure there’s legal evidence attached to the document

Legal evidence is required to be considered advanced type, so when we check the signature we can tell if it’s fully legal and that it is uniquely linked to the signatory. Here are some examples of legal evidence which will be registered in the audit log:

Timestamp

Timestamping allows a trusted third party (Timestamp Service Provider) to claim that a document has been electronically signed at a specific date and time that were set by state protocols. 

Timestamps make it easier to determine whether a document has been altered after signing, which makes them a powerful piece of evidence in the event of a legal dispute. They are useful to prevent fraudulent commercial transactions. Our solutions include default timestamps for free to ensure the integrity of the signed content.

Signer location

Signer location is another feature from Viafirma, especially when collecting signatures on-the-go. 

Clear examples are carriers, deliverers or healthcare professionals with informed consents. In these cases we would normally use the biometric signature via tablet, iPad or a device specially designed for this purpose.

SMS/email OTP

It’s a short code sent to the device or email of the person at the time of signing. It allows the signatory to eSign wherever, on any device.
