Michigan police asked scientists to create a 3D copy of the victim of the murder to unlock his smartphone

American police officers turned to researchers from the University of Michigan, specializing in the field of biometrics, with a request to help unlock the smartphone of a man who became a victim of murder with artificial fingers, printing them on a 3D printer, writes Fusion .

Currently, the police of Michigan continue the investigation, and all the details of the case are not disclosed, however, according to law enforcement officers, the blocked smartphone of the murdered man (the model of the device is not specified) may contain information that will help to find the criminal. You can unlock the device using a fingerprint or by entering the installed password. The second method is possible only with the participation of the manufacturer. This is probably why the police decided to turn to scientists, mindful of the recent confrontation of Apple and the FBI.

According to N+1 , the police handed the researchers at their disposal scans of the prints of all ten fingers of the deceased, since it is not known which one was used to unlock the smartphone, although, most likely, it was an imprint of the large or index finger.

Having received these materials, scientists using a 3D printer created copies of all ten fingers of a late man. Then, a thin -conducting layer of metal was applied to the casts so that the capacitive smartphone scanner recognized them like real prints. Currently, scientists are testing copied prints in the laboratory. In case of successful completion of tests that will take several weeks, casts will be transferred to the police.

It is worth noting that police representatives turned to researchers from the University of Michigan after they discovered a video that shows the scientists in February a method of hacking the fingerprint scanner with the help of an ordinary jet printer on YouTube.
