Lockjaw

Encrypts data into archives via facial recognition

Overview

This program uses webcam video feed to register your face in its database, allowing you to encrypt files into an archive. You may use you face as a key to then decrypt your archives.

Demo

Watch the video below Watch the video

Requirements

How to start

python -m face.py

Register

Register your face with option 1, your face will be scanned, a password will be generated alongside the scan, and you may encrypt files.

List out files you'd like to archive and encrypt For example

Choose files to encrypt:
images\potter.jpg images\granger.jpg images\weasley.jpg

Choose a name for the archive

Choose a snazzy name for the archive: 
yearbook

It is now stored in an encrypted archive.

Accessing encrypted archives/decrypting

Select option 2 to decrypt archives] Your face will now be scanned, and be matched with the database of stored face encodings.

Once a registered user has their face scanned, they will be welcomed and may select to decrypt their files.

Scanning for your gorgeous face...
Welcome Master Dumbledore. What would you like to decrypt?
yearbook.zip
Uncompressing...
Uncompressing and decryption successful!

If you see the above success text, you should see the archive contents unzipped.

Design

All face encodings, usernames, and passwords are stored in pickle files. Pickle files are able to store objects for use in another run of the program.

clear_database()

empties face encodings, username, and password pickle files.

Face encodings

These are the meat of what is returned from the face recognition and openCV libraries. For our purposes, it merely is a face.

Passwords

The password generated along with a face is 1000 characters with letters, numbers, caps, and special characters. A brute force would take several millenia to crack it. That said, the pickle file is not a safe means to save passwords. It would make sense to generate a one way hash on a smaller password, then compare the hash with the stored database one way hash. This is how most passwords are stored.
