The National Computer Virus Emergency Response Center recently found that more than 20 mobile applications for take-away, medical care and online education were suspected of privacy irregularities in the "Net 2020" special action. Including the American food mall.

The original intention of the privacy agreement is to protect citizens' privacy, but after we check the consent, once we agree, the address, phone number, chat record, address book, photos, text messages and call records filled in the APP can be freely collected and analyzed by the apps. How will these collected privacy information be used? We can see that under the current big data, the takeaway you ordered is always as expensive as others. You browsed the house purchasing website today, and the agent will call you tomorrow; Search for a skirt on the shopping website, and then all kinds of apps are links to skirts. Privacy agreement, in a sense, just like the "food ingredient list" in reality, is a long, complicated, vague and obscure privacy agreement with professional names one after another.
