Smart User Liveliness

Smart User Liveliness

Smart User Liveliness ensures that the document signatory is actively present during the eSigning process. This AI-based technology verifies the real-time presence of the individual in front of the device, guaranteeing that the person initiating the eSign is indeed live and genuine.


By analysing facial cues and other behavioural patterns, Smart User Liveliness ensures signer identity, enhancing the security and integrity of electronic signatures.

Signing Journey

Here, we outline the signing process with Smart User Liveliness. The signer needs to follow the steps mentioned below to complete the Liveliness check in their signing journey.


  1. Invitee will receive the invitation to eSign the document.

  2. After OTP verification, the signer will see the instructions for Face Capture with Smart User Liveliness.

These instructions must be followed strictly for successful signer’s verification.

  1. Next, a camera preview will be shown to the signer. Here they can switch between front or back cameras and also ensure the face is properly visible.

  2. After that, the signer must follow on-screen instructions and place their face in the oval within the set time frame.

Case I: Success

  • The signer will see a success message with 3 face captures.

  • If the signer is unsatisfied with the outcome, they can click on Retry for another face capture attempt.


Case II: Failure

  • The signer encounters a failure message (e.g., Time Out or Threshold not matched).

    • In case of Time out, the signer needs to retry the face capture attempt and place their face in the oval within the set time frame. 

    • In case, the Threshold is not matched, the signer needs to retry the face capture (If additional attempts are allowed) and make sure they are in a well-lit environment with no accessories on like spectacles, headphones, etc.


  1. Click Proceed in the bottom right corner to eSign the document.


Face Match + Smart User Liveliness

If you have configured both Smart User Liveliness and Face Match then the process of both will be carried out simultaneously in a single face capture. The signer will not be required to separately perform Face Match and Smart User Liveliness. The results of both will be shown on a single screen as well.


If Smart Face Liveliness fails then Face Match will not happen at all and only the liveliness result will be shown. If both Liveliness and face match are successful, a success screen will be shown.


The remaining attempts displayed will reflect the lower count between Smart Face Liveliness and Face Match. Once attempts for either verification are exhausted, the signer cannot retry both liveliness and face match.


For example, Face Match has 2 retry attempts and Smart Face Liveliness has 3 retry attempts. Then, After 2 retry attempts the signer cannot do both, neither Face Match nor Liveliness.


Best Practices for Signers - Smart User Liveliness
