What technology is being used in the world to track new coronavirus cases?

Since new coronavirus infection (COVID-19) spreads from human to human, it is important to investigate the 'behavior of the infected person' in order to investigate the spread of the epidemic. IT technology site

VentureBeat explains what kind of technology is used to investigate the behavior of such infected people.

The technologies the world is using to track coronavirus --and people | VentureBeat

◆ Smartphone
The ' contact tracking method, ' which thoroughly examines the person who has contacted the infected person, is a method of identifying infected persons that has been used since the latter half of the 19th century. However, in recent years, smartphones have made the contact tracking method more efficient. In one example, Apple and Google are working together to develop the COVID-19 Contact Notification API.

There are two methods of tracking infected persons with a smartphone: a 'centralized approach' in which contact data is managed on a server, and a 'distributed approach' in which information is not managed on the server. Regarding the centralized approach, VentureBeat pointed out a privacy problem, 'Personal information is collected on the server, which may lead to information leakage.' In fact, it is pointed out that the official COVID-19 tracking app in North Dakota, USA, sends location information and other information to third parties.

The API jointly developed by Apple and Google uses a decentralized approach.

◆ Wearable devices and applications
In the United States, some local governments are taking steps to track the behavior of COVID-19 infected individuals using wristbands or shackle monitors.

In addition, a wristband type device that has the function of measuring vital signs such as body temperature and blood pressure is being used to monitor the health condition of people who have completely cured COVID-19.

Also, many applications for COVID-19 have been developed. COVID-19-related official app ' RivCoMobile ' in Riverside County, California has a function to 'report' people who are holding large-scale gatherings and people who do not wear face masks in important business situations. I will.

◆ Thermography
Since infection with COVID-19 may cause fever, at airports and military bases, ' thermography ' that remotely measures and visualizes the heat quantity of an object is used to identify infected persons. According to VentureBeat, thermography has the advantage of being highly anonymous, unlike face recognition technology.

However, because there are many asymptomatic pathogen carriers who do not show symptoms such as fever and cough, and they are infectious during the incubation period until fever, it is useful to use thermography for identifying COVID-19 infected persons. There are also voices that question sex. FLIR, a thermal camera maker, has stated that 'Our products cannot be used to diagnose new coronaviruses.'

VentureBeat says, 'Some thermography is inaccurate, and it's not possible to tell if you have a fever because of an illness or if you're just exercising and warming your body.'

◆ Face recognition technology
China and Russia are implementing quarantine using

face recognition technology . Using face recognition technology, it is possible to keep track of 'how a specific person moves' using surveillance cameras in the city.

On the other hand, face recognition technology has privacy issues. 'Face recognition is the most dystopian technology,' VentureBeat said, raising concerns about face recognition systems. He points out that the COVID-19 pandemic emergency could be used as an 'excuse' to deploy a surveillance system using facial recognition technology.

◆ Unmanned aerial vehicles such as drones
Unmanned drones and self-driving cars are beginning to be used in medical institutions to reduce human contact.

However, legislation regarding the operation of unmanned aerial vehicles is not perfect. Electronic Frontier Foundation in order to take advantage of the drone for the purpose of COVID-19-related monitoring and tracking, we should enact guidelines on how to use claims have been, we are warned about the dangers.

VentureBeat is a technology that can reduce human-to-human contact and reduce the COVID-19 epidemic, but it is also a potentially dangerous technology to operate as part of a police state, '' VentureBeat said. I will.
