murder victim
Image source: Kārlis Dambrāns few months, Apple has been involved in a legal battle with the high-profile FBI on mobile security. If you recall, the controversy began after Apple refused to create a customized version of iOS that would have allowed authorities to bypass lockscreen on the iPhone used by a terrorist San Bernardino. In defending the position of Apple, Tim Cook said boldly that the FBI wanted Apple to create the "equivalent of the cancer program."
Ultimately, the legal dispute fizzled after the FBI was able to buy software from a third party allowed to bypass the lockscreen without Apple's help. With this backdrop, we recently stumbled upon a report detailing a new way that the law enforcement authorities in Michigan were able to access a locked iPhone a murder victim, without any help from Apple or even having to expose hundreds of thousands of dollars to a third party.

According to a report Fusion , police in Michigan recently needed access to the iPhone lock belonging to a murder victim. Naturally, the authorities believe that the information on their phone can provide clues and help them solve the murder investigation underway.
Initially thwarted by the tactile identification system that the user has set up on his phone, the police has not reached out to Apple but contacted a professor at Michigan State University Computer Science named Anil Jain who had significant expertise in biometric related technologies. In turn, Jain, with the help of a doctoral student named Sunpreet Arora, 3D printing used to create a replica version of the fingerprints of the victim on police engravings basic already had on file. And because the authorities are not sure of numbers of victims used to access their phone, Jain was busy creating replicas of all the fingers of the victim.
But of course, this is just the first part of the process. Because Touch ID on the iPhone is only receptive to an object with an electric current, an artificial replica of a fingerprint, no matter how accurate, is not enough to access the device itself.
That said, there is a solution in the works.
most fingerprint readers are used on phones capacitive, meaning they rely on the closure of small electrical circuits to work. finger ridges cause some of these circuits to get in touch with each other, generating an image of the fingerprint. The skin is sufficiently conductive to close the circuits, but the normal 3D printing plastic is not so coated fingers Arora 3D printed in a thin layer of metal particles so that the fingerprint scanner can read.
There is not yet a foolproof method. Arora is still refining the technology, and they have not yet given to the police finger to try to unlock the phone from the victim. But Arora said that in a few weeks, once it is tested enough fingers in the laboratory, it will reuse. Then the police will try to use printed 3D models of the fingers of a dead man to unlock the phone.
Overall, this is a pretty clever workaround, but the whole process might be for nothing. Remember, iPhones that have been disabled for more than 48 hours require a password for full access to the device.
This, of course, will simply put back to square font and in the same position that the FBI was there a few months.
