Prevent crimes on the train!Suspicious person detection "Defender X" amazing ability | FRIDAY Digital

"Defender X" is in the limelight as a means to prevent such incidents.

When humans are tense, transient "tremor" due to mental stress appears on the skin of the face. "Defender X" is software that detects the "shake". When detected, the person is surrounded by a red frame on the screen. Developed for military use in Russia during the Soviet era, it was installed at all entrance gates at the 2014 Sochi Olympics and detected about 2,600 people during the period, 92% of which were dangerous goods possessions and drugs. Verification results have also been obtained that the visitors were fraudulent visitors who possessed or did not have an admission ticket.

In Japan, including the 2018 Ise-Shima Summit, retailers now prevent shoplifting and voyeurism, food companies prevent foreign substances from entering, manufacturing industries prevent goods from being taken out, and warehousing industries prevent products from being pulled out. Introduced in the industry. It was also introduced at the Tokyo Olympics at Shuzenji Station in Shizuoka, where a bicycle race was held with spectators.

"In Japan, it seems that private security companies and companies have introduced it. I think it would be good if railway companies also introduced it."

This is Nobuo Komiya, the first Japanese to complete the Graduate School of Criminology at Cambridge University and teach criminology at Rissho University.

Finding signs of suicide or people in need ...

"'Defender X'is also called a suspicious person pre-detection system, but I think it's better to make the detected person a'calling target'. Humans are nervous for various reasons. Maybe I'm in trouble, or if it's a station, I'm about to jump into the railroad tracks. It's impossible for humans to see it. But, "Defender X. If there is a person surrounded by red, the guards and station staff will ask, "Are you okay?" "Are you having any problems?" There is a possibility. "

However, whenever he proposes to introduce a new technology, tech skeptics oppose it. There are two main reasons. One is that it will be a violation of human rights.

"Now, the face recognition system is a hot topic as one of the crime prevention systems, but I think that this may violate human rights more. This is because the face must be authenticated in advance. The image of the person must be included. Whose face should be included is a person with a history. The railway company obtains the consent of the person with a history of crime for crime prevention. Is it okay to use it without it?

On the other hand, "Defender X " only checks the physiological phenomenon on the spot. It doesn't collate with anything, it doesn't store any data, so it doesn't violate human rights. "

Another reason technology skeptics disagree. "It may not be effective." It seems that there was a certain effect at the Sochi Olympics ...

"I think it's theoretical, but I don't really know, because it hasn't been introduced by railroad companies yet. I think if it doesn't violate human rights, I'd give it a try. So the data If it doesn't work, don't introduce it. It's not scientific to assume that it doesn't work from the beginning. Even when developing a new drug, if the safety is confirmed, it will be effective next. I'm going to a clinical trial to confirm my sex. It's the same. "

Even at the police station, there is no movement to introduce it. Rather, Mr. Komiya says that it may not even be talked about.

"I think we're lagging behind in catching up with the latest technology. In the United States, each patrol officer has a tablet , but in Japan it's hard to put a computer in a police box . Information leaks. But what if you think there is a risk, think about preventing it. I was able to build a civilization because I invented the fire.

On the other hand, there is still a risk of arson and misfire by using fire, but no one says to ban the use of fire. If you say "I won't do it because there is a risk" from the beginning, nothing new will come out to the world. "

The battle begins with competing for the few. As technology evolves, for example, water shortages will be resolved and water conflicts will disappear. Komiya says that technology is needed to live peacefully and happily.

One of them is "Defender X". If it is effective in preventing crime and suicide, I think you should consider introducing it.
