Methods and terminals for generating and reading 2d barcode and servers

A terminal for reading a 2D barcode, wherein the terminal comprises:

• a processor and a memory storing instructions that, when executed by the processor, cause the processor to;
• acquire a 2D barcode including an information access address;
• scan the 2D barcode, to obtain the information access address included in the 2D barcode, the information access address being for accessing private information;
• send the information access address to a server through a network, so that the server searches for corresponding private information according to the information access address;
• receive the private information returned, through the network, by the server;
• and
• use the private information as a reading result of the 2D barcode;
• wherein the information access address at least includes an information identifier of the private information;
• and
• the instructions that cause the processor to receive the private information returned, through the network, by the server further cause the processor to:
• receive, after the server finds the private information according to the information identifier of the private information included in the information access address, the private information returned through the network.

A server, wherein the server comprises:

• a processor and a memory storing instructions that, when executed by the processor, cause the processor to;
• receive an information access address sent, through a network, by a terminal and for accessing private information;
• search prestored private information for private information corresponding to the information access address;
• and
• return the found private information to the terminal through the network, so that the terminal uses the private information as a reading result of a 2D barcode;
• wherein the information access address includes an information identifier of the private information;
• and
• the instructions that cause the processor to search the prestored private information for private information corresponding to the information access address further cause the processor to:
• search the prestored private information for the private information corresponding to the information identifier includes in the information access address.
