# Liveness Detection in Biometric Time Tracking

> Anti-spoofing technology in facial recognition time clocks that detects actual live persons versus photos, videos, or masks. Uses AI to analyze micro-movements, depth, and biological signs. Prevents time fraud attempts using photos or videos of authorized employees, ensuring genuine presence verification.

## Details

## Overview

Liveness detection ensures the person clocking in is physically present, not a photo or video, preventing sophisticated time fraud.

## How It Works

**Analysis Methods**
- Micro-movements (blinking, breathing)
- Depth perception (3D vs 2D)
- Skin texture analysis
- Blood flow detection
- Challenge-response (blink, smile)

**AI Processing**
Machine learning identifies authentic vs spoofed attempts.

## Fraud Prevention

**Detects**
- Photos held up to camera
- Video playback on screens
- Printed images
- Digital screens showing faces
- Masks or 3D models

## Leading Implementations

- Timeero (liveness detection)
- Jibble (AI-powered verification)
- Modern facial time clocks

## Security Level

Provides high confidence in physical presence, preventing common bypass attempts.

## Pricing

Included in advanced facial recognition time tracking systems.
