Project Showcase • Digital Design + Security
A modern access-control system built with secure authentication concepts (PIN + OTP + RFID + Biometric) and digital logic design using VHDL.
Auth Methods
Logic Design
Verification Layer
Live Lock Simulation
This is a website UI demo (not real lock control).
Modern security systems focus on strong authentication, convenience, and tracking.
Secure numeric access with keypad input and lockout after failed attempts.
One-Time Password layer to protect from unauthorized entry and brute-force attacks.
Contactless access using cards or NFC-enabled smartphones for quick entry.
Fingerprint recognition for high security and personalized authentication.
Remote control lock via smartphone apps and smart home integrations.
Maintain user logs, timestamps, and security alerts for monitoring.
A secure step-by-step authentication workflow.
User enters PIN / OTP / RFID / Biometric input.
System validates input using authentication rules and logic design.
Authorized user triggers unlocking mechanism.
System stores access logs and raises alerts on suspicious attempts.
Smart locks need more than convenience — they need protection.
This project also explores digital circuit design using Truth Table, K-map and VHDL simulation.
Using Boolean expressions derived from K-map simplification, the lock logic was implemented using VHDL for simulation.
