This document provides a project definition for a fingerprint-based security system. The system will use an AT89C51 microcontroller to analyze fingerprint scans and activate a motor if an authorized fingerprint is detected. Fingerprint data will be stored on the microcontroller even without power. The system block diagram outlines the fingerprint sensor, oscillatory circuit, microcontroller, relay, motor driver and motor components. Software will include a device driver for fingerprint detection and motor control. Serial communication and LCD interfacing is also specified.

PROJECT DESCRIPTION
Personal Safes are revolutionary locking storage cases that open with
just the touch of your finger. These products are designed as secure storage
for medications, jewelry, weapons, documents, and other valuable or
potentially harmful items. These utilize fingerprint recognition technology to
allow access to only those whose fingerprints you choose. It contains all the
necessary electronics to allow you to store, delete, and verify fingerprints
with just the touch of a button. Stored fingerprints are retained even in the
event of complete power failure or battery drain. These eliminates the need
for keeping track of keys or remembering a combination password, or PIN. It
can only be opened when an authorized user is present, since there are no
keys or combinations to be copied or stolen, or locks that can be picked.
