With the continuous increase of express delivery business volume and the popularization of express real-name systems, the issue of personal privacy leakage on express delivery bills has attracted widespread attention. It is understood that in order to prevent the leakage of personal information, some express delivery on the market have adopted the form of private face-to-face packaging, and the name and phone number of the consignee will be marked with mosaics; however, such private face-to-face forms have not yet been fully popularized. The representative of the National People's Congress and the receiver and dispatcher of the Shanghai Postal Center Bureau of China Post Group Corporation, Chai Xianxing, said that the technology of express delivery privacy is not difficult, but it will reduce the delivery efficiency of couriers. Relevant platforms stated that they faced multiple problems in the implementation process and were working hard to solve them. They were also issuing privacy stickers with the package, hoping to solicit better suggestions from the public.
