# IAD (Injection Attack Detection)

### **What does this product solve?**

The **IAD** (Injection Attack Detection) by Facephi incorporates **advanced security controls aimed at detecting and preventing injection attacks** during facial Biometric Verification processes.

Its goal is **ensure that the biometric capture comes from a legitimate and trustworthy source**, avoiding fraud attempts through the use of manipulated videos, virtual cameras, digital reproductions, or synthetic content.

### How the IAD module works against injections

Facephi's IAD acts on the **client and server side**, integrating specific controls to:

* **Detect unreliable capture environments**
* **Identify manipulations of the video or image flow**
* **Analyze metadata and capture signals** generated during the biometric process
* **Evaluate injection and presentation attempts** before validating identity

During Face Capture, the component **Selphi IAD** generates a **encrypted package (IAD bundle)** that contains images and security metadata. This package is then analyzed by the platform to determine whether there is an attempt at an injection attack.

At Facephi, the IAD module is complemented by **behavioral biometrics**, incorporating an additional layer of security based on contextual analysis and user interaction patterns. This integration makes it possible to strengthen fraud detection, continuously assess risk, and ensure more secure and reliable Identity Verification processes.

### **Integration**

IAD is integrated using Facephi's standard mechanisms:

* **Facephi APIs (Identity API)**\
  They allow communication between the client's systems and the platform to start, query, and manage verification and authentication operations.
