# Face Match

The **Face Match** feature enhances document security by leveraging facial recognition technology to verify the signer's identity. It matches the signer's face image, captured during the signing journey, with a reference image—such as an uploaded identity document or face verification photo—provided by the sender when sending the document.

This ensures that only the intended recipient is authorized to sign, offering an additional layer of identity verification.

## Activate Face Match

#### V3 Workflow

1. On the **Invitee Card**, click **Invitee Level Options**.
2. Toggle ON **Enable Security Features**.
3. Enable **Capture Photo**.
4. Enable **Face Match**.
5. Upload a **Reference Image**: An image uploaded by the sender, used to verify the invitee's identity during the signing journey by comparing it with the photo captured at the time of signing.
  - This may include identity documents such as a PAN Card, Aadhaar Card, or onboarding forms. For accurate facial recognition, crop or mask the document to show only the signer's face before uploading.
6. Set the **Retry Attempts**: Specify the number of attempts the signer can make to successfully capture and match their face.

#### Workflow Creation

1. On the **Invitee Card**, click **More Options**.
2. Toggle ON **Advanced Security Features**.
3. Enable **Capture Photo**.
4. Enable **Face Match**.
5. A **Reference Image**: An image uploaded by the sender, used to verify the invitee's identity during the signing journey by comparing it with the photo captured at the time of signing. (**Note:** It needs to be uploaded by the workflow runner while sending the document.)
6. Set the **Retry Attempts**: Specify the number of attempts the signer can make to successfully capture and match their face. (**Note:** Workflow runner cannot modify the Retry Attempts.)

**Note:** The workflow runner cannot disable this if enabled by the workflow creator, and vice versa.

#### V4 Workflow

1. On the **Invite** stage, select the invitee card.
2. In the right panel, open the **Settings** tab and go to **Security Options**.
3. Enable **Capture Photo**, then enable **Face Match**.
4. Upload a **Reference Image** — an image used to verify the invitee's identity by comparing it with the photo captured at signing.
  - This may include identity documents such as a PAN Card, Aadhaar Card, or onboarding forms. For accurate facial recognition, crop or mask the document to show only the signer's face before uploading.
5. Set the **Retry Attempts** — the number of attempts the signer can make to successfully capture and match their face.

**Note:** Whether the workflow runner can modify this setting depends on the [field properties](https://knowledge.leegality.com/document-execution/workflows/v4/setup-configuration/field-properties) set by the workflow creator.

## Signing Journey

1. During the signing journey, the signer is presented with a set of on-screen instructions to follow.
2. After ensuring the prerequisites mentioned on the instruction page are met, click **Proceed**. The signer must grant camera access for photo capture.
3. Click **Capture** to take the photo.
4. Next,
    - **Successful Face Match:** The invitee will see a success message and can proceed to sign or review the document.
    - **Failed Face Match:** If the captured face does not match or no face is detected, the invitee will be prompted to retry.
