Project Name: Offline Multi-Factor Authentication Smart Safe

Overview

Traditional single-point authentication safes are vulnerable to key theft or password cracking. Our project is a standalone, battery-powered smart safe equipped with a three-in-one multi-factor authentication (MFA) system: edge AI facial recognition, fingerprint recognition, and RFID. This system is designed for secure and intuitive interaction, verifying biometric data locally and triggering the physical electromechanical lock instantly, without relying on vulnerable cloud networks or smartphone apps.

Unique Features

Unlike commercial smart locks that process data via Wi-Fi (which poses significant privacy and cybersecurity risks), our system performs all biometric matching entirely at the edge. Crucially, the system architecture is controlled by a strictly non-blocking finite state machine (FSM). This FSM logic supports a “high-security mode” (enforcing strict sequential multi-factor authentication), resisting brute-force attacks. These features are typically found in enterprise-grade security systems, not consumer-grade desktop safes.

Brief Technical Overview

The core component is a custom-designed PCB employing a dual-MCU architecture: an ESP32-S3 (or other hardware) handles the DVP camera interface and edge AI algorithms, while an STM32 manages the FSM and peripheral polling. The main challenge in the hardware design lay in building a robust power distribution network and high-current MOSFET drive circuitry. This ensured that the 12V electromechanical electromagnetic lock could safely withstand peak transient currents without causing voltage drops to sensitive logic circuitry.

Logic Circuit Teaching Board

Featured Project

Partners: Younas Abdul Salam, Andrzej Borzecki, David Lee

The proposal our group has is of creating a board that will be able to teach students about logic circuits hands on. The project will consist of a board and different pieces that represent gates. The board will be used to plug in the pieces and provide power to the internal circuitry of the pieces. The pieces will have a gate and LEDs inside, which will be used to represent the logic at the different terminals.

By plugging in and combining gates, students will be able to see the actual effect on logic from the different combinations that they make. To add to it, we will add a truth table that can be used to represent inputs and outputs required, for example, for a class project or challenge. The board will be able to read the truth table and determine whether the logic the student has created is correct.

This board can act as a great learning source for students to understand the working of logic circuits. It can be helpful in teaching logic design to students in high schools who are interested in pursuing a degree in Electrical Engineering.

Please comment on whether the project is good enough to be approved, and if there are any suggestions.
