Police officers of Michigan State contacted of Anil Jain- Professor in Michigan State University, for recreate a dead man's finger, Who is the victim of the murder case. And law enforcement investigators beleived that his phone might contain some useful information about the case.
The victim’s phone hasn’t yet been unlocked – Jain has created replicas of all ten digits, but is still working to refine them so the plastic fingers coated with metallic particles can be read by a fingerprint scanner as easily as human fingers, which are more conductive.
When thinking about its implications and consequences in future, this technique could make everyone vulnerable who uses biometric security to protect the privacy of their smartphones.
Since fingerprints are the unique and all time the constant identity of a person, there is a risk of having someone steal a fingerprint using a high-resolution photo and recreating it that way.
Since the investigation is ongoing, much details about the technique are not available.
The best solution, for now, is to disable any biometric sensor enabled on your smartphone, just in case you don't want the police or anyone else to 3D print a replica of your fingers and unlock it with ease. Rather set a secure password to lock your device.
