US police has reproduced a victim 3D fingerprint to unlock an iPhone

Apple refuses to cooperate with the authorities when it comes to unlocking terminals iPhone, or iPad tablets, which set a security code and / or a fingerprint and a police station in the US has resorted to a method quite unusual to gain access to a victim’s terminal.

We are talking about a person who was killed, and to get access to data terminal or police in the US called for the creation of a mold 3D finger person, this mold with imprint used to unlock the device and using or trying to get access to data from the device.


Police called for the creation of molds 3D all 10 fingers of the victim, a laboratory in Michigan managed to do this, but unfortunately it is not known how many chances does the police to get access to the device, given the safety measures implemented or by Apple in the iOS.

Specifically, iOS requires a security code if the mark has not been used to unlock more than 48 hours, or if the terminal was restarted, but after three scans wrong the footprint is needed the realization of exactly the same procedure to gain access to data.

A 3D printed finger alone often can’t unlock a phone these days. Most fingerprint readers used on phones are capacitive, which means they rely on the closing of tiny electrical circuits to work. The ridges of your fingers cause some of these circuits to come in contact with each other, generating an image of the fingerprint. Skin is conductive enough to close these circuits, but the normal 3D printing plastic isn’t, so Arora coated the 3D printed fingers in a thin layer of metallic particles so that the fingerprint scanner can read them.

Although police did not know how successful it could be accessing data, death does not attempt, and in the future, if these procedures are done quickly enough, they could indeed allow accessing data from devices.
