# Liveness Web SDK

Liveness Web SDK provides a robust solution for face authentication by identifying and distinguishing between real and fake faces.  The SDK uses the device's front camera to process image frames, verify the user's presence, and return the final image captured during the process.

### Features

* **Lightweight:** Lightweight bundle size, doesn’t incur performance overheads.
* **Easy Integration:** With just a few lines of code, you can integrate our SDK into your web applications.
* **Customisable Options**: Configure the face detection parameters like detection timeout, frame shape, text content, etc to suit your specific requirements. The SDK offers a theming customisation option which helps you to integrate it retaining your brand's visual identity.

### Integration

VIDA Web SDK can be integrated into your application using either a script tag or an npm package. The flow includes secure token retrieval, SDK initialization, face detection, image submission, and result handling through callbacks.\
