YEK

Yek is a prototype of an on-hand password manager that redefines how users interact with account safety and passwords on a laptop computer. It is an embedded device that acts as your personal butler to memorize passwords. With a yek device and a fingerprint scan, you can login to any of your accounts by connecting to any computer device through a bluetooth connection. Yek acts as a keyboard and types in your login information (username and password) to the selected textbox of a login page, so that you do not have to remember your unique and strong passwords. It can fit in your pocket just like a physical keychain, and yet it can hold 63 of your accounts through a computer application.

Code

When prototyping, we developed in Arduino then ported it to AVR C. We have included both for your convenience.

PCB

The pcb was designed in Eagle. There is one error in the PCB if you are planning to send it out (or printing it in house if that's your slice of pie). The pins on the Battery JST plug are flipped. This is not a major issue but change it if you would like. We did not so that the professors could see our the equivalent PCB we printed.

Computer Application

The computer application was written in Java and is available as a runnable .jar file that works on Windows, Mac, or Linux, and just requires that Java 8 be installed. The app, uses a library called jSerialComm to communicate with the Yek through a serial port connection.

Building the Yek

If you want to use Arduino

To build with Arduino: Download the following libraries:

U8g2 Screen Library:

https://github.com/olikraus/U8g2_Arduino

FRAM Library:

https://github.com/adafruit/Adafruit_FRAM_I2C

Fingerprint scanner:

https://github.com/sparkfun/Fingerprint_Scanner-TTL

Bluefruit library:

https://github.com/adafruit/Adafruit_BluefruitLE_nRF51

Open Arduino and compile the .ino in the folder Yek_arduino

If you want to use GCC

Use the code in Yek_firmware folder

To build with GCC:

install avr-gcc (GCC) 7.2.0 using your favorite package manager (this will take 2 hours... sorry)
download LUFA
update the path to lufa into makefile
run make in the folder
