If you鈥檝e ever flashed the peace sign at the camera or given a little wave in the direction of the lens (so, essentially, if you鈥檝e ever taken a picture), you mayyyyy have unwittingly provided hackers with just the keys they need to create a little (or a lot) of chaos in your world. That鈥檚 because hackers can now steal your fingerprints from the pics you post online. *Gulp!*

Isao Echizen from Japan鈥檚 National Institute of Informatics spoke to Tech Insider, revealing that hackers are now able to copy and then reproduce our fingerprints from high-res pics we鈥檙e posting. Once the criminals have your fingerprint, they can use it to access your smartphone or break into restricted areas.

And just to prove his point, Isao and his team conducted an experiment attempting to do just that. Shockingly, they were able to reproduce fingerprints that were a 鈥渘ear perfect match.鈥 Yikes.

There hasn鈥檛 been any recorded cases of hackers doing this (yet!), and frankly, most pics aren鈥檛 of the right quality to make it possible to grab your prints (not to mention the fact that they鈥檇 have to steal your phone before gaining access). While you鈥檇 likely have to be a spy or something similar to warrant fear of your fingerprint being used to access an off-limits area, it still might be a good idea to stick with what鈥檚 expected to be the most popular selfie pose of 2017 instead of flashing that peace sign the next time you and your bestie take a pic together.
