[Document Creation](https://help.cincel.digital/en/user-guides-signing-and-managing-documents?hsLang=en#document-creation) # Liveness Test in Cincel: Identity Verification The Liveness Test, or Identity Verification, is an advanced security measure in Cincel that ensures the person signing a document is truly who they claim to be. It adds an extra layer of protection and trust to your most important agreements.   --- ### **What is it? And why use it?** The **Liveness Test** is the digital equivalent of requesting an official ID in person before signing a contract. It is a biometric process that associates a signer's identification (through their INE or passport) with their real-time presence (via a “selfie” or video). This process has three main objectives: - **Prevent fraud:** Ensures that only the identity holder can sign. - **Strengthen security:** Adds a verification layer to your most sensitive documents. - **Increase evidentiary validity:** Generates irrefutable evidence of the signer's identity.   --- ### Steps to request identity verification in a document - #### **Configure the document to be signed in Cincel** Click the "Create document" button, upload your document, enter the requested data, and click continue. ![](https://help.cincel.digital/hs-fs/hubfs/undefined-Feb-25-2026-11-27-34-1874-PM.png?width=688&height=375&name=undefined-Feb-25-2026-11-27-34-1874-PM.png) - #### **Activate the liveness test** Click on the 3 dots that appear in the box of the signer for whom you want to request identity verification and select the "Edit" option. ![](https://help.cincel.digital/hs-fs/hubfs/undefined-Feb-25-2026-11-27-34-6746-PM.png?width=688&height=375&name=undefined-Feb-25-2026-11-27-34-6746-PM.png) - #### **Save the changes** Check the "Request liveness test from this signer" box and click continue. ![](https://help.cincel.digital/hs-fs/hubfs/undefined-Feb-25-2026-11-27-34-4579-PM.png?width=688&height=375&name=undefined-Feb-25-2026-11-27-34-4579-PM.png) **Done!** With this last step, you will have successfully requested the liveness test from the signer. 💡**Tips and suggestions:** Remember that you can activate or deactivate the liveness test request per signer before sending the document for signature. --- ### **The Signer Experience:** If you request a Liveness Test, the signer will be guided through an intuitive and secure process, without the need to have a Cincel account. - **Start the validation.** Upon opening the document, the system will indicate that Identity Verification is required before signing and will ask the signer to click "Validate". - **Scan the official ID.** The signer will be asked to take a photo of the front and then the back of their valid INE or passport. - **Perform the Liveness Test.** Next, the system will request a "selfie," asking the user to follow on-screen instructions (e.g., move closer to the camera) to confirm it is the same person. - **Sign the document.** Once the system has validated the identity, the signer can proceed to sign the document as usual. --- ### **How to activate the Liveness Test** The Liveness Test is activated by the document creator during the signer configuration process. It is a feature available as an add-on ('Add-On') or included in Cincel's **Business or Enterprise** plans.   💡**Cincel Tip:** By requiring a Liveness Test, you raise the security of your agreements to the highest level. It is the best practice for critical documents such as high-value contracts, promissory notes, or any agreement where the signer's identity is fundamental. - [Quick guides](https://help.cincel.digital/en/quick-guides?hsLang=en#main-content) - [Security](https://help.cincel.digital/en/quick-guides?hsLang=en#security) - [First Steps and Basic Concepts in Chiseling](https://help.cincel.digital/en/first-steps-and-basic-concepts-in-chiseling?hsLang=en) - [News and updates](https://help.cincel.digital/en/news-and-updates?hsLang=en) - [User Guides: Signing and Managing Documents](https://help.cincel.digital/en/user-guides-signing-and-managing-documents?hsLang=en#main-content) - [Document Creation](https://help.cincel.digital/en/user-guides-signing-and-managing-documents?hsLang=en#document-creation) - [SIGNATURE](https://help.cincel.digital/en/user-guides-signing-and-managing-documents?hsLang=en#signature) - [Account Management, Teams and Billing](https://help.cincel.digital/en/account-management-teams-and-billing?hsLang=en#main-content) - [Account Management](https://help.cincel.digital/en/account-management-teams-and-billing?hsLang=en#account-management) - [Team Management](https://help.cincel.digital/en/account-management-teams-and-billing?hsLang=en#team-management) - [Legal Validity and Regulatory Compliance (Mexico´s Legal Framework)](https://help.cincel.digital/en/legal-validity-and-regulatory-compliance-mexicos-legal-framework?hsLang=en) - [Security and Core Technology](https://help.cincel.digital/en/security-and-core-technology?hsLang=en) - [Integrations and APIs for Developers](https://help.cincel.digital/en/integrations-and-apis-for-developers?hsLang=en) - [Troubleshooting and frequently asked questions](https://help.cincel.digital/en/troubleshooting-and-frequently-asked-questions?hsLang=en) - [Glossary of Terms](https://help.cincel.digital/en/glossary-of-terms?hsLang=en) [![Chill listening crop-3](https://help.cincel.digital/hs-fs/hubfs/Cincel%202025-%20320x132-02.png?width=57&height=24&name=Cincel%202025-%20320x132-02.png "Chill listening crop-3")](https://www.cincel.digital/branding) Cincel® 2024 / D.R., Grupo Cincel que conforma LUMIT DLT S.A.P.I.
