Abstract

When pass information via 2-d code(such as Quick Response Code ), the information holder like to dispatch different info to different receiver via the same 2-d code, so that to make better communication efficient and better privacy protection. This disclosure provides a way to group different receivers and different group can retrieve different information.

cascaded 2-d code

When pass information via 2-d code(such as Quick Response Code), the information holder like to dispatch different info to different receiver via the same 2-d code, so that to make better communication efficient and better privacy protection. This disclosure provides a way to group different receivers and different group can retrieve different information.

Take express delivery as example, a product will be delivered from province A to province B, the detail address in province B will be generated to a 2-d code. We can define like this: - seller cannot decode the 2-d code. - express delivery worker in province A can only decode the province information, so that the product can be delivered to province B. - express delivery worker in province B will know the detail transitions. - the final express delivery worker may know the contact number.

In this case, user's information can be protected in a possible limitation.

The core idea of this invention is to get the different information base on the same 2-d code for different user. With this, we can protect people privacy better and take significant to the logistics industry. 1. Authorization Server: Server provides a mechanism that to support user with different authorities. It responses to: a. Give authority to a user. b. Record the map between user and authority level, when user request to logon the client, it will return a key to user. c. Use the left side(none used for current 2-d code) of 2-D code to gen...
