Expansion: "Beijing Health Treasure" is a small program that is convenient for individuals to inquire about their own health status related to epidemic prevention, and can be used by all personnel in Beijing and those who enter (return to) Beijing.
Instructions for use of "Health Treasure": Search for "Beijing Health Treasure". When you use it for the first time, you only need to enter your name and ID number and perform face recognition, so you can query your health status. The query results include centralized observation, home observation and no abnormality, which are marked with red, yellow and green respectively. The status information generated on the mobile phone only keeps two digits before and after the "surname" and ID number, which realizes the double minimization of data collection and personal privacy.
