Overview

Face Match is an enterprise-grade biometric engine designed for high-precision 1:1 facial reconciliation. Architected as a robust backend-to-backend solution, it allows partners to programmatically submit two distinct image payloads, a "Selfie" image and a "Reference Document" to determine identity parity. Unlike rigid systems limited to specific ID types, Face Match is document-agnostic, capable of calculating biometric similarity across a diverse range of source materials, including national passports, driver’s licenses, or internal corporate credentials.

Key Features

	Technical Implementation	Strategic Value
Agnostic Source Matching	Algorithmic flexibility to compare real-time selfies against any provided reference document (KTP, Passport, KITAS, etc.).	Universal Utility: Enables a single integration to support multi-national onboarding or varied document requirements.
Backend-to-Backend API	Secure, RESTful architecture allowing partners to pass image data directly from their existing infrastructure.	Architectural Freedom: Offers total control over the user interface and data flow, ensuring the engine fits into any established workflow.
Biometric Similarity Scoring	Generates a high-confidence similarity coefficient based on unique facial geometry and landmark mapping.	Objective Risk Control: Replaces subjective manual verification with standardized, data-driven identity assurance.
Resolution Resilience	Engineered to extract high-fidelity templates even from suboptimal, low-resolution, or aged document portraits.	Operational Efficiency: Minimizes false rejections caused by varying document print qualities or environmental factors.
