The fingerprint authentication function installed in many of the latest smartphones is so convenient that once you use it you can no longer return to unlocking with passcode or pattern input. In order to release the lock of the smartphone equipped with the fingerprint authentication function, it turned out that the American police asked experts to create a fingerprint with a 3D printer and release the terminal.

According to Dr. Anil Jain who studies the biometrics system at Michigan State University, "Since proof that leads to the criminal may remain in the smoked victim's smartphone, create a fingerprint with the 3D printer, release the lock The police asked that I want you ". Although Dr. Jain did not reveal much, due to the case under investigation at the time of article creation, the police seized the fingerprint of the victim at the time of previous arrest and handed the scan data to Dr. Jain.

"I do not know which finger the victim used for fingerprint authentication of the smartphone.There are many users who set the thumb and index finger for fingerprint authentication, but this time the fingerprint replicas of all 10 fingers We created it, "said Dr. Jain. Many fingerprint authentication functions installed on smartphones adopt the "electrostatic capacity method" which discharges and reads the distance to the fingerprint grooves, and it is not easy to understand the conductivity by merely creating a fingerprint replica Since there is no terminal can not be released.

Dr. Jain is an expert on fingerprint authentication, it was published in February 2016 that a movie containing a printout of the scanned fingerprint, a special conductive ink applied on top of it, breakthrough smartphone fingerprint authentication There is. Also at the request of the police, we have devised a method to coat replica of fingerprint created with metal powder and break through fingerprint authentication. Although the replica of the fingerprint itself is complete, it is still in the testing stage and Dr. Jain does not hand over the replica to the police. I will submit it to police two or three weeks after several tests have been completed.

According to Fusion of IT related media, the act of unlocking the smartphone using the fingerprint replica created by the police by the 3D printer,Amendment to the Constitution of the United States Article 5"No one shall be compelled to become a witness against himself in criminal cases, nor will it be deprived of life, freedom or wealth without relying on the proper procedure of the law" There is a possibility. If you investigate the possessions of any innocent victim and find the evidence of a different crime committed by the victim, it may violate amendment Article 5.

However, because the victims have already died, even if evidence of some kind of crime is found from the victim's smartphone, the victims will not be in a more bad state than the current "death", so the police act is modified Some experts say they do not violate Article 5.

According to the court, legal treatment is distinguished between "fingerprint" for unlocking and "passcode" stored, and the stored passcode is protected under Article 5 of amendment , The fingerprints attached to the human body may not be protected by Article 5 amendment. In a trial conducted in Virginia state in 2014, suspects must release a lock on a smartphone seized by a fingerprint in the case of an order from a law enforcement agency, but the password stored in the head is It says not to followAwardWas issued.

In this case, Dr. Jain said, "We are pleased by the police, because the police still have not unlocked using fingerprint replicas created with 3D printers, so we can not tell whether the act violates the law. We are cooperating with each other because we are having fun working together. "
