Inkjet printer fools smartphone fingerprint scanner into unlocking the device

One of the hardest to obtain pieces of the puzzle required to pull this off, is a good quality fingerprint of the device's owner. This needs to be a print that is registered on the device you are looking to unlock. The image of the fingerprint is then scanned into a PC. Keep in mind that this must be done with the image reversed so that when you print it, the fingerprint comes out looking "normal."
Take your inkjet printer with the special AgIC produced ink cartridge in place. Print the scanned fingerprint image on to the special glossy AgIC paper. You must use a setting of 200 dpi, making sure that the size of the print equals the size of a real fingerprint. The resulting image of the fingerprint can be used to trick the scanner into unlocking the device, allowing you to gain entry to certain smartphones.
Phones like the Samsung Galaxy S6 and the honor 7 have been unlocked by tricking the fingerprint scanner with this method. This method will work on other fingerprint readers as well. The fingerprint "spoof" was discovered by Michigan State University, and you can check it out in action by clicking on the video below.

FBI no longer seeks special version of iOS. Now asks Americans to register their finger prints at the local police department.

They dont need to - law enforcement CAN, legally, get you to unlock your phone if its protected with fingerprint. Its the passcode that they cant get you to hand over. Despite the minor wrinkle, great joke though. Boy I'm fun at parties.

My Nexus 6p requires either a pin or pattern on boot if you use the fingerprint scanner for unlock. It also requires it if you pull the device off a charger and if it sits for I believe four hours with no activity.

It is extremely funny though. What are the chances a thief will have your fingerprints together with you phone? They are very small, so let them have these printers, gummibears etc. they still need my fingerprint too....And before they have set up their little lab, I have wiped/locked down the phone......

Video doesn't really have me entirely convinced, though that said it does make sense that they can't be as secure as the full sized with humidity and everything else to safeguard. But he needs to show using a finger that isn't the one needed to unlock, right there he's using left index finger which is also the one needed for unlock. That said the fingerprint scanner's are probably never going to be 'safe' from tampering, no safety measure is, the main point is to make it difficult, and getting a good fingerprint and similar is quite difficult, and you can't really brute force a fingerprint scanner, at least not effectively yet, because its a physical 'key' where a password and pin code is not physical but entirely software based, so it can be brute forced easily, so finger prints are still quite a bit more secure then pin/passcodes/draw patterns
