bRUID ACS

3-D Secure Access Control Server

3DS 2.3 · ICBA Biometric · Issuer-Controlled

Authenticate with biometrics.
Controlled entirely by the Issuer.

bRUID ACS is a high-performance 3-D Secure authentication module where biometric verification is completely controlled by the Issuer Host - not delegated to third parties. Powered by the ICBA Framework, it replaces OTPs and passwords with fingerprint, face, and iris authentication across frictionless and challenge flows. Certified with Visa Secure, Mastercard SecureCode, RuPay SecurePay, Amex SafeKey, and JCB J/Secure.

System Architecture

3-D Secure Authentication Platform

bRUID ACS handles the complete 3DS authentication lifecycle - from risk evaluation and frictionless routing to biometric challenge flows and out-of-band verification. ICBA biometric authentication replaces OTPs at every critical touchpoint, with full control at the Issuer Host.

3DS 2.3 Protocol

Full EMVCo 3-D Secure 2.3 implementation with frictionless and challenge-based authentication flows

ICBA Biometric Auth

Fingerprint, face & iris verification controlled entirely by the Issuer Host - replacing OTP and passwords

Risk-Based Routing

Adaptive risk evaluation with device fingerprinting, behavioral analysis & geo-anomaly detection for frictionless routing

Frictionless Flow

Low-risk transactions auto-approved without cardholder interaction using real-time risk scoring and trust signals

Challenge Flow

High-risk transactions trigger ICBA biometric challenge - face, fingerprint, or iris instead of OTP

OOB Authentication

Out-of-band biometric verification via mobile SDK and push-approval for in-app authentication scenarios

Device Fingerprinting

Collect and analyze device signals - browser, OS, screen, IP, timezone - to build trust scores and detect anomalies

Custom Security Rules

BIN/MCC/IP/amount-based rules with configurable thresholds for issuer-specific fraud prevention policies

Issuer Host Control

Complete authentication decisioning at the Issuer - biometric verification, risk scoring, and approval all within issuer infrastructure

Network Certification

Certified with Visa Secure, Mastercard SecureCode, Amex SafeKey, JCB J/Secure, RuPay SecurePay & SecurePlus

High-Load Architecture

Horizontal scaling for peak online traffic with sub-100ms authentication response times

Compliance

EMVCo 3-D Secure, PA-DSS, PCI-DSS certified with tamper-evident audit logging and role-based access

ICBA Integration

Issuer-Controlled
Biometric Authentication

Unlike third-party OTP providers, bRUID ACS keeps biometric verification entirely within the Issuer Host. The issuer decides when to challenge, which biometric modality to use, and controls the entire authentication lifecycle - no external dependencies, no OTP vendors, no latency.

Frictionless Authentication

Low-risk transactions pass through silently using device trust, behavioral signals, and transaction history - zero cardholder friction.

Biometric Challenge

High-risk transactions trigger ICBA biometric verification - fingerprint, face, or iris - directly at the Issuer Host. No OTP, no SMS dependency.

Risk-Based Decisioning

Real-time risk engine evaluates device fingerprint, geolocation, velocity, and behavioral patterns to route between frictionless and challenge flows.

Out-of-Band Verification

Mobile SDK push-approval with ICBA biometric verification for in-app authentication - secure, fast, and completely under issuer control.

Capabilities

Authentication Capabilities

Frictionless Authentication

Low-risk transactions auto-approved using device trust scores, transaction history, and behavioral patterns. Zero cardholder interaction - sub-100ms response time.

Biometric Challenge

High-risk transactions trigger ICBA biometric challenge - fingerprint, face, or iris verification at the Issuer Host. No OTP dependency, no SMS latency, no phishing risk.

Mobile SDK & OOB

Out-of-band authentication via mobile SDK with push-approval and in-app biometric verification. Rich APIs for custom integration with issuer mobile apps.

Adaptive Risk Engine

Real-time risk scoring combining device fingerprinting, geolocation, velocity checks, merchant anomaly detection, and BIN/MCC/IP/amount-based custom rules.

Device Fingerprinting
