1️⃣ Edge Device (Face + Gait)

This is the device where attendance is marked.

It captures your face and how you walk. It checks if the person is real (not a photo or video).

2️⃣ Fraud Detection Engine

It looks for any suspicious or fake activity.If anything looks wrong, it creates an alert and keeps a log.

3️⃣ Privacy Controller

It keeps your personal data safe and private.

Biometric + Behavior-Based Verification

Facial recognition, behavior analysis. Liveness detection to avoid spoofing (photos).

Audit & Traceability Engine

Immutable logs (e.g., blockchain-style hacking protection). Real-time alerts on suspicious attendance patterns.

Anomaly Detection AI

ML model trained to detect abnormal logins (outside of hours, multiple locations). Repetitive geo-spoofing attempts.

Ethical Oversight Module

Model explainability (e.g., breaking down images) or limited data retention. Role-based access and control over biometric use.

🔐 1. Access Control Devices (RFID/Biometric)

These devices capture attendance data using RFID cards or biometric scans (e.g., fingerprint or face recognition).

🔄 2. Data Ingestion Service (REST API / Kafka)

Collects the raw attendance data from devices and sends it to the backend using APIs or message queues like Kafka for real-time processing.

🧠 3. Backend Microservices

Employee Service: Manages employee information.
Attendance Service: Validates and records attendance logs.
Analytics Service: Generates insights like attendance trends or anomalies.

🗄️ 4. Database Layer

Relational DB (MySQL/PostgreSQL/SQL): Stores structured data like employee records and attendance logs.
NoSQL DB (MongoDB): Stores semi-structured/unstructured data like logs or metadata.

🌐 5. Frontend (HR/Admin Web App)

Allows HR/admin users to view, edit, and manage attendance data, analytics, and reports through a user-friendly web interface.

🔔 6. Notification Service

Sends alerts or notifications (e.g., absent alerts, regularization reminders) via email, SMS, or app notifications.
