Recently I came across this amazing proof-of-concept which proves that our physical keys can be copied just by their images !!
What??? no, Are you serious??
Yeah, call this a technological leap in optics and image processing, but this is reality. And the professors at University of San Diego's Jacobs School of Engineering have successfully experimented this.
The original article (quite old though) can be found here. You can read about the technical details.
When I was reading this, I was thinking of all the places where my keys are susceptible to this kind attack. Like Airport/Hotel/Banks scanning - where you need to empty your pockets. Can you think of such places?
Well, the possible places are many but the question is: Whether we are ready to counter such kind of attacks? may be not.
As always, the best thing to do is to be vigil & pay attention to the details. As a security measure, never upload images with sensitive information (e.g. keys, driving license, important numbers etc.) and even if you have to, then make sure that you blur out the important parts.
Be safe & ride safe !!
