Age of NO PASSWORD

Problem with today's password

Everyday, we use passwords for so many places such as login to my desktop, open my garage door, lock/unlock safe, unlock phone, access my broadband router and etc. Remembering those different password is very difficult and waste of memory. So we need a safe and robust way to access the resource without entering password again and again.

Solution to get rid of the passwords

I am going to build a face recognition garage door lock with Xilinx KV 260. Currently we have RF remote for garage door but I usually forget to carry the remote with me. I thing biometric recognition is the key to all unlocking because no one can infiltrate and impersonate Xilinx KV 260 module face recognition. Because Xilinx KV 260 is industrial grade device. Even though I am planning to do garage door use case, this can be applied to any place where need safe and secure access such as lock/unlock house doors, lock/unlock/start vehicle/motor bike, lock /unlock cargo container and face recognition based attendance system.

Setting up Xilinx KV 260 (Kria KV 260)

Setting up Kria is very straightforwad thing to do. I will briefly explain the essential steps here. For more information the Xilinx guide would be best place to to start.

Preparing SD card with petalinux image

First you need to copy the petalinux image into the SD card. Using link below you can get the petalinux image.

Once you get the image file you can use Balena Etcher to write image to SD card. These instructions are clearly documented under Xilinx guide so I am not going to redocument everything here.

Wiring things up

Here, for the demonstration I am using solenoid push pull switch to show the behavior of electrical lock. I am using 12V solenoid switch and 3V relay and 1N4007 back EMF protection diode for this set up.
