I hack you in my eyes

Jan Krissler (Jan Krissler), the same biometric hacker, who eloquently demonstrates the "vulnerability of the thumb" and who hacked from a photo of the German defense minister , can see your password / PIN from the eye glitter.

As practice has shown, the eyes are not only a mirror of the soul, but simply a mirror, which means you can peek into it, what is happening on your screen.

The ratio of the size of the reflection of a 5-inch display on the eye, depending on the resolution of the camera. The distance is 30 and 60 cm. Everything above the red line can be reconstructed.


Formula for calculating the size of the image

Protection measures

Random keyboard (helps with low resolution images), password entry eye-tracker (and it can be cracked), biometric authentication? Good luck

PS

Reflections, grimacing,
Break free
Smiling in cold blood
Or crying, but without pain ...
Mirrors are watching us,
Learning to even listen,
Be thoughts and dreams
Distorting our souls.
Drowning in the mirror of desire,
Movement slows down ...
We were given a spell,
We were caught by the reflections ...
