Secure Universal ID Tracker
A next-generation biometric identity verification platform engineered for transportation security, passenger identification, and encrypted authentication at scale.
What is the SUIT System?
The Smart Universal Identification Tracker is a privacy-first biometric verification platform designed to secure passenger identity across transportation checkpoints. It addresses luggage theft and identity fraud by linking verified biometric data to passenger records without storing any raw images.
Prototype Status: SUIT is a research prototype developed as a proof-of-concept. It has not been deployed in real-world airports. Performance metrics are based on controlled testing environments.
Identity Verification
Multi-factor biometric authentication using facial landmark analysis with liveness detection to prevent spoofing attacks.
Biometric Processing
468-point facial mesh extraction, normalized and encrypted on-device before any data leaves the edge unit.
End-to-End Encryption
AES-256-GCM encryption with unique nonces and timestamped payloads to prevent replay attacks.
Transport Integration
Designed for airport check-in, customs, and boarding - seamlessly matching passengers to their luggage.
How It Works
A five-stage pipeline from camera capture to passenger verification, with encryption at every step.
Camera Input
Pi Camera Module v3 captures live video at 30fps with threaded background reading.
Encrypted Capture
AES-256-GCM encrypts the biometric embedding on-device. Raw frames are immediately deleted.
Identity Processing
MediaPipe Face Mesh extracts 468 3D landmarks. Liveness detection prevents spoofing.
Database Matching
Encrypted payload sent via HTTPS to the backend. Timestamp prevents replay attacks.
Passenger Verified
Match result controls the physical gate: green LED + gate open, or red LED + buzzer alert.

Facial Mesh Encryption
Watch the full biometric pipeline in action: real-time facial mesh detection extracts 468 landmark points from your face, displays the raw coordinate data, then encrypts everything with AES-256-GCM - all happening live in your browser.

Privacy First - Zero Data Retention
All processing happens entirely in your browser using MediaPipe and the Web Crypto API. No images, landmarks, or encrypted data are sent to any server. Raw camera frames are deleted from memory immediately after landmark extraction. The encrypted payload shown above exists only in your browser's memory.
Key Features
Every component of the SUIT System is engineered for security, speed, and reliability.
Secure Passenger Search
Query the encrypted passenger database with partial or full name matching. Results are decrypted only at the point of verification.
Step-by-Step Verification
Two-stage checkpoint system: Departures (check-in) and Arrivals (customs). Each stage independently verifies passenger-luggage pairing.
Partial Name Recognition
Fuzzy matching algorithm identifies passengers even with incomplete or misspelled name entries, reducing friction at checkpoints.
Encrypted Camera Capture
AES-256-GCM encryption applied to biometric data on-device. Raw camera frames are deleted from memory immediately after processing.
Database Matching
Encrypted embeddings are compared against stored records via HTTPS. Timestamped payloads prevent replay attacks.
Identity Fraud Prevention
Liveness detection via blink analysis prevents photo and video spoofing. Anti-replay timestamps block recorded payload attacks.
Biometric Processing
468-point facial mesh extraction using MediaPipe. Landmarks are normalized for scale and translation invariance across 5 averaged frames.
Transport Security Integration
Designed for airports, train stations, and border control. Physical gate control via GPIO relay with LED and buzzer feedback.
SDG Alignment
The SUIT system directly contributes to five United Nations Sustainable Development Goals by replacing paper-based processes with secure digital biometric verification.
Industry, Innovation & Infrastructure
SUIT introduces biometric-based infrastructure at airport checkpoints, replacing outdated manual verification with an innovative edge-computing solution that modernizes transportation security.
SUIT: Deploys Raspberry Pi edge units with advanced facial recognition at every checkpoint, creating a smart infrastructure layer.
Sustainable Cities & Communities
By streamlining airport processes and reducing congestion at checkpoints, SUIT contributes to more efficient, safer, and sustainable transportation hubs.
SUIT: Reduces average check-in processing time, decreasing passenger congestion and improving the overall airport experience.
Responsible Consumption & Production
SUIT eliminates the need for paper-based baggage tags and printed boarding passes by replacing them with digital biometric verification linked to RFID.
SUIT: Removes single-use paper tags from the luggage lifecycle, preventing thousands of paper tags per flight from entering landfills.
Climate Action
Reducing paper consumption in the aviation industry directly lowers the carbon footprint associated with paper production, printing, and waste disposal.
SUIT: Contributes to a paperless airport model, aligning with IATA's target of net-zero carbon emissions by 2050.
Peace, Justice & Strong Institutions
SUIT strengthens institutional security by providing tamper-proof biometric verification that prevents identity fraud and luggage theft at airports.
SUIT: Uses AES-256-GCM encryption and liveness detection to ensure only verified individuals can claim their luggage, reducing theft and fraud.
Elimination of Paper Tags
Why Paper Tags Must Go
Every year, the global aviation industry prints billions of paper baggage tags - adhesive labels attached to suitcases at check-in that are scanned, torn, and discarded after a single flight.
These tags contribute to deforestation, chemical waste from thermal printing, and landfill overflow. They are also unreliable - barcode smudging and tag detachment cause millions of bags to be misrouted annually.
SUIT replaces this entire process with a digital pipeline: an RFID chip is assigned to each suitcase and linked to the passenger's biometric profile. No paper is printed, no adhesive is used, and no physical tag can be lost or tampered with.
