Third Party Signature Security

What are the available options to improve traceability with a third party signature? How can I validate that the account I selected, received and signed my contracts? What authentication options are available to our contract signing process?

1. ID Verification

Enhanced authentication using government photo IDs

For the highest level of signer identification, OneSpan Sign’s ID verification option quickly determines whether the signer’s government photo ID is authentic. 

Allow your signers to take a photo of their passport, driver’s license, or other government-issued IDs directly from their mobile device. Machine learning algorithms analyze the authenticity and validity of the photo ID to determine whether the ID document is genuine.

2. Biometric Verification

Ensure signers are who they say they are

For a higher level of security and confidence, pair ID verification with the biometric comparison option. Signers are asked to take a "selfie" with the camera on their mobile device. Advanced algorithms extract biometric data from the image and compare it to the image on the authenticated ID document to determine whether the signer is genuine.​ 

Liveness detection involves the signer performing an action, for example blinking or moving their head, to prove that they are genuinely present and that a static image or video is not used fraudulently.

3. SMS Authentication​

Add a layer of security to your consumer-facing transactions​

OneSpan Sign generates a one-time PIN that is sent to the signer’s phone. The signer enters it into a login page and gains access to the documents that require signatures

4. Q&A

Present challenge questions to your signer before they can view documents

These questions are referred to as “shared secrets”, because the sender needs to know something about the signer to create the questions. The questions and answers are known by both parties and pre-selected ahead of time. Common questions include the last four digits of a Social Security Number (SSN) or an application ID number. The signer must correctly answer one or more questions before being granted access to the electronic documents that require signature.

5. Certificate-based IDs

Use personal digital certificates to verify the identity of signers

OneSpan Sign can leverage local and remote digital certificates issued by trusted authorities and partners to verify the identity of signers at the point of signing. When using a personal digital certificate to e-sign a document, OneSpan Sign verifies the certificate’s status and the action requires a PIN or password to complete the signing process. 

When using a digital certificate issued by a qualified Trust Service Provider (TSP), this creates a Qualified E-Signature (QES) in accordance with the requirements of the European Union’s eIDAS regulation.
