Extracting PIN Codes from Keypads with Thermal Imaging Fingerprints
Well this is kind of shocking. Of course your physical fingerprint will remain on most things you touch, but on keypads your finger depress of the button could leave a heat signature for “over a minute” and allow someone using thermal imaging to see what numbers you pressed!
A few days ago I was able to get my fingers on, and under, an infrared camera. I had already heard before that the thermal signature of fingerprints is visible for quite some time — but what surprised me was that we were still able to see them for over a minute…
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
