Face Capture with IAD

Differences from standard Face Capture

The Selphi IAD Component is functionally equivalent to the Selphi Component standard, incorporating additional security controls aimed at detecting video injection attacks and untrusted capture environments.

The integration, configuration, and usage flow of the component are the same. The main functional difference is the inclusion of the field iad in the result (SelphiResult), which contains the antifraud analysis information prepared for server-side verification.

A new License is required for its use, and the dependency on the standard component must be replaced with:

implementation "com.facephi.androidsdk:selphi_iad_component:$version"

This component has two important restrictions:

• Devices with at least 3 GB of RAM.

• Front camera with preview of 1920x1080 or higher.

Introduction

Face Capture with video injection attack detection is performed through the Selphi IAD Component.

This component is responsible for capturing a user's selfie and extracting the most relevant facial features, incorporating a set of preventive security controls aimed at detecting untrusted environments. During the process, the following steps are performed, among others:

• Internal camera and permission management.

• Detection of spoofing attempts using videos or manipulated camera sources.

• Guided assistance during Face Capture.

• Generation of biometric templates and user images.
