Shoulder Surfing using OpenCV

Shoulder surfing is when a person watches over the shoulder of another looking for passwords to be typed. This activity has been around since the first keyboard was created. And, with the addition of tablets and touch screen PCs, shoulder surfing is easier than ever. Even though most passwords are hidden by asterisks, the On-Screen-Keyboards used on modern mobile devices (phones & tablets) leave us more vulnerable to shoulder surfing attacks.

Checkout  this article to see how one developer used OpenCV to extract passwords from camera feeds. Next time be careful when you type in a password on your tablet while waiting for the metro or sitting at your local Starbucks. There might be a hidden camera nearby!
