Deliverables and Key Performance Indicators

KPIs

For the project to be considered a success, the following Key Performance Indicators (KPIs) are to be met:

  1. Authentication Success Rate (%)

    • Formula: (Successful Authentications / Total Authentication Attempts) × 100
    • Purpose: Measures reliability and efficiency of user authentication.

  2. Tamper Detection Accuracy (%)

    • Formula: (True Tamper Detections / Total Tamper Events) × 100
    • Purpose: Evaluates the effectiveness of magnetometer and ultrasonic sensors in detecting real threats versus false positives.

  3. Blockchain Logging Integrity (%)

    • Formula: (Logged Events Verified / Total Events Triggered) × 100
    • Purpose: Ensures that all events (access, tamper, etc.) are immutably recorded and retrievable.

  4. Bluetooth Detection Latency (ms)

    • Formula: Average time from Bluetooth signal detection to initiation of passcode prompt
    • Purpose: Measures responsiveness of the system in recognizing authorized devices.

  5. Credential Revocation Response Time (seconds)

    • Formula: Average time from revocation command to enforcement
    • Purpose: Measures how quickly the system can react to revoked access, affecting real-time security.

Deliverables

Ultimately, the project will deliver on the following items:

  1. Base Node (B-L4S5I-IOT01A)

    • Bluetooth-based user authentication
    • User credential management (MAC address, alias, passcode)
    • BLE communication with sensor and camera nodes
    • Access control logic and servo/speaker actuation
    • Tamper and intrusion detection via sensor data
    • Blockchain-based event logging
    • Passcode entry via keypad

  2. Mobile Node (M5Stack Core2)

    • Bluetooth pairing with base node
    • Real-time feedback on authentication status

  3. Sensors Node (B-L4S5I-IOT01A)

    • Ultrasonic: Visitor presence detection
    • Magnetometer: Tamper detection
    • BLE-based real-time data transmission to base node

  4. Actuation Subsystem

    • Servo motor: Simulated door lock/unlock

  5. Web Dashboard (TagoIO)

    • Real-time system status and event log display
    • Visual verification of access attempts
    • Immutable blockchain event audit trail

  6. Blockchain Integration

    • Logging of all access events and alerts
    • Ensures verifiable, tamper-resistant records
