Prevent crimes on trains! The amazing power of the suspicious person detection “Defender X

Suicide bombing-type crimes… “Defender” to detect suspicious persons X (Japanese only)

On November 8, a man sprayed liquid on the floor of a Kyushu Shinkansen train and set it on fire. on the night of Halloween, October 31, a man in costume cut a passenger with a knife, sprayed liquid on him, and set him on fire in a train traveling near Kokuryo Station on the Keio Line in Chofu City, Tokyo. On November 6, a knife-wielding man appeared near Monzennakacho Station on the Tozai Line. On November 6, a knifeman appeared near Monzennakacho Station on the Tozai Line, terrorizing people using the train.

The “Defender X” is gaining attention as a way to prevent such incidents.

When a person gets nervous, a transient “tremor” appears on the skin of the face due to mental stress. “Defender X is software that detects this “shaking”. When detected, the person is surrounded by a red frame on the screen. It was developed for military use in Russia during the Soviet era, and was installed at all entrance gates to the Sochi Olympics in 2014, detecting about 2,600 people during the period, 92% of whom were in possession of dangerous goods or drugs, or were unauthorized visitors without entrance tickets.

In Japan as well, the Ise-Shima Summit in 2018 and other events have been introduced in various industries, such as shoplifting and spy photography prevention in the retail industry, foreign object prevention in food companies, goods removal prevention in the manufacturing industry, and goods extraction prevention in the warehousing industry. At the Tokyo Olympics, the system was introduced at Shuzenji Station in Shizuoka, where a cycling race was held with spectators.

“In Japan, it seems that private security companies and businesses have introduced this system. In Japan, it seems that private security companies and businesses have introduced this system, and I wish railroad companies would do the same.

It can also detect signs of suicide and people in trouble. It can also detect signs of suicide and people in trouble…

The “Defender X The “Defender X” is also called a pre-detection system for suspicious persons, but I think it would be better to designate the detected person as the “target of the call. People get nervous for various reasons. They may be in trouble, or if they are at a station, they may be about to jump onto the tracks. It’s impossible to tell with the human eye. However, the “Defender X If a person is surrounded in red, a security guard or station attendant will ask, “Are you okay? Is there something wrong with you? Are you in trouble? This alone could prevent suicides and crimes.

However, whenever I propose the introduction of new technology, I am always met with opposition from technology skeptics. There are two main reasons for this: one is that it would be a violation of human rights.

“One is that it would be a violation of human rights. I think this system is much more likely to violate human rights, because in order to authenticate a person’s face, a picture of the person’s face must be entered in advance. If you ask me whose face I would put in, it would be someone with a criminal record. Is it okay for a railroad company to use the face of a person with a criminal record for security purposes without obtaining his or her consent?

In contrast, the “Defender X In contrast, “Defender X” only checks the physiology of the person in question. It doesn’t check against anything, and it doesn’t store any data, so it doesn’t violate human rights.

There is one more reason why the technology skeptics are against it. “There is another reason why technology skeptics are against it: “It may not be effective. It seems to have had a certain effect at the Sochi Olympics. ……

“Theoretically, I think it does, but in practice, I don’t know. I don’t know what it is, because it hasn’t been introduced in the railroad companies yet. As long as it doesn’t violate human rights, I think it’s a good idea to try it. If it doesn’t work, then don’t introduce it. It is not scientific to assume from the beginning that it will not work. When developing a new drug, once the safety of the drug is confirmed, it is then sent to clinical trials to confirm its efficacy. It’s the same thing.

There is no movement to introduce the system at the police station either. In the police department, there is no movement to introduce this technology, or rather, it is not even being talked about, Komiya said.

“I think they are lagging behind in catching up with the latest technology. In the U.S., there is only one policeman on patrol. One tablet. In the U.S., each patrol officer has a tablet, but in Japan, there is only one computer at a police station. In Japan, it is hard to put one computer in a police box. In Japan, it’s hard to put one computer in a police station. In Japan, it is very difficult to put a single computer in a police station, so what if information is leaked? But if you can think of a risk, you can think of a way to prevent it. We were able to build our civilization because we invented fire.

On the other hand, there is still a risk of arson or fire loss by using fire, but no one is saying that we should ban the use of fire. If you say from the beginning, ‘I won’t do it because it’s risky,’ then you won’t be able to bring anything new into the world.

Conflict begins when we compete for what we have less of. As technology evolves, for example, water shortages will be solved, and there will be no more conflicts over water. Mr. Komiya says that technology is also necessary to live peacefully and happily.

One such technology is “Defender X”. If it is effective in preventing crimes and suicides, I think it would be a good idea to consider introducing it.
