Launched in late February by Alibaba's Ant Financial, the QR code is available in more than 200 cities across China via the popular Alipay wallet app. The different colors — green, yellow, and red — indicate people's health status. A green QR code allows free access to public places like subways, shopping malls, and supermarkets. A yellow QR code requires a seven-day quarantine, while a red QR code requires a fourteen-day quarantine.

Government App Tracking Boosts AI During Covid-19
While QR code checkpoints are becoming standard across China, neither the company nor officials have explained how the system decides which color to assign. However, it appears that the QR code bases its colombia telegram database decisions on the user’s location history combined with coronavirus information. So a yellow or red code could be given to someone who has visited cluster areas or had contact with an infected person.

There is still no consensus on “how to marry with privacy rights,” but the government’s immediate responsibility is to take the necessary measures to stop the deadly epidemic. A huge amount of data has become available thanks to the authorities’ constant monitoring of a large number of apps that feed artificial intelligence in China with a large amount of data during Covid-19.

New healthcare technologies to combat coronavirus
In the first weeks of the outbreak, much was written in scientific journals around the world about how Baidu had developed an algorithm that takes just 27 seconds to solve the secondary structure of Covid-19 RNA , 120 times faster than the best classical algorithms. On January 30, the tech giant, which runs the country’s largest search engine, opened up its LinearFold prediction algorithm for free to global genetics agencies and research institutes. This scientific feat came in the early stages of the outbreak in China, and has been followed by other AI-powered solutions to the coronavirus in China. These advances in public health could set a new precedent for preventing future pandemics.
