After receiving the two-dimensional code and the coding algorithm, the target contact person can acquire information contained in the two-dimensional code in two ways, one way is that after receiving the two-dimensional code, the two-dimensional code is directly cracked by the coding algorithm to directly display the information contained in the two-dimensional code, and the other way is that the target contact person cracks the two-dimensional code by triggering the coding algorithm to acquire the information contained in the two-dimensional code. After the target contact receives the two-dimensional code, the two-dimensional code is decoded according to the stored coding algorithm to obtain information, the information contained in the two-dimensional code can be directly displayed according to the coding algorithm received by the target contact, or the target contact decodes the two-dimensional code by triggering the coding algorithm, and the information contained in the two-dimensional code is displayed after the two-dimensional code is decoded.

In the embodiment of the invention, information can be edited in information editing software, for example, editing information is input in a document interface, a two-dimensional code is generated from the information in a document through a two-dimensional code coding algorithm, the generated two-dimensional code, a coding algorithm selected to be used and document information are stored in a folder, when a user wants to send the information to a target contact person, the two-dimensional code is called from the folder of the stored file and is sent to the target contact person, and the target contact person decodes the two-dimensional code through the stored corresponding coding algorithm to obtain the information.

For example, a user selects one coding algorithm from multiple coding algorithms in a client, finds a old page through an address book in the WeChat by using a communication tool such as WeChat, sends the selected coding algorithm to the old page through the WeChat, configures and stores the old page in the WeChat after the old page receives the coding algorithm through the WeChat, edits information through an information editing interface of the WeChat, clicks an encryption option in the WeChat, selects the coding algorithm which is sent to the old page before, generates a two-dimensional code by the coding algorithm which is sent to the old page before, sends the two-dimensional code to the old page, decodes the two-dimensional code according to the coding algorithm which is configured and stored before after the old page receives the two-dimensional code, and acquires the information.

The user can directly send the two-dimension code to the target contact person through the communication tool, when the user and the target contact person are in the same group, the user can also select to send the coding algorithm to the target contact person for configuration and storage, and then the two-dimension code is sent to the group, so that the target contact person can check information contained in the two-dimension code sent to the group by the user through the coding algorithm.
