Passkeys are becoming popular across consumer and enterprise companies. This project walks through how to implement Passkeys from scratch. The project will focus on the cryptographic operations that take place during registration and authentication as you interact with a fully functional application that implements Passkeys.

Facial recognition is becoming more mainstream - from unlocking your phone to boarding an airplane. This project walks through how to implement your own facial recognition system from scratch. We will focus on basic facial recognition, with added technologies for deepfake and liveliness detection.

"My voice is my password" was the science fiction like tag-line in the 1992 Sneakers movie. While we do not see it as mainstream in 2025, this project walks through how voice ID works from scratch.

Fingerprint recognition systems are extremely popular for identifying a person. The use of fingerprints, palm patterns and related are used in a variety of use cases including authentication systems, fraud forensics analysis and more. This project implements a basic fingerprint based recognition system from scratch.

There has been a lot of academic research around key stroke dynamics, and if it can be reliably used to continuously identify a user behind a computer. This project implements a key stroke dynamic based authentication system for the purpose of extending an existing session or terminating a session before it has expired.
