China developed a camera to detect suicide bombers

Chinese scientists are developing a sophisticated camera. When scanning the crowd through this device, one will see a barometer of stress on each person's head, suicide bombers will be marked with a red face .

This special camera can detect people in extreme stress . Stress causes a series of physical manifestations such as changes in heart rate, facial expressions, body temperature. All these expressions can be observed from a distance. However, indicators are not always reliable. If you exercise a lot, a person can learn how to control your heart rate.

That's why Mr. Chen Tong, associate professor of electronic information engineering at Southeast University in Chongqing, China is studying another indicator of the concentration of oxygen in the blood .

New technology will detect suicide bombers among crowds

Using high-level spectroscopic imaging technology - the kind of technology that checks information through electromagnetic spectrum, Mr. Chen and his team developed a 'stress sensor' that measures the amount of oxygen in the blood through the body parts exposed like the face. Mr. Chen said: 'The higher the stress level, the higher the level of oxygenation in the blood'.

Mr. Chen's research was carried out in the context of China concerned about the security situation when a series of deadly attacks occurred in public. The culprit could be religious extremists who stabbed at train stations until the unconscious people set fire to buses .

Mr. Chen said: 'They look and behave like normal people, but the level of mental stress must be extremely high before they cause attacks. Our technology can detect these people to help those who enforce tragedy prevention and prevention legislation. '

When looking at a crowd through this device, people will see a mental stress gauge appear on each person's head, the suspect will be marked with a red face.

Researchers say they can use this technology to identify people with high levels of oxygen in the blood due to stress rather than relying on looks.

These technology experiments have yielded positive results. However, putting technology into practice poses a new challenge. The biggest obstacle is to analyze remote data.

For example, a police officer who works at a bus stop will need to filter a huge amount of data and handle it in a short period of time. Small devices cannot handle data at this rate so the police will have to send information to analyze elsewhere via wifi.

However, this technology is still very promising for the scientific community. However, people who are concerned about technology if applied will be abused by the government.
