As described above, the inventor has found that when a user uses some software with sensitive user information (such as APP of a bank), the software remotely stores the user information with extremely high security, such as user identity information, passwords, information, and the like, in a server. However, for an interactive process with a high delay requirement, the user experience is seriously affected and even serious loss is caused due to the fact that the interactive process cannot respond in time due to network congestion and a series of time-consuming operations of acquiring user information from a remote place and then encrypting and decrypting the user information are performed. However, if the user information is stored locally in the client in the form of text, the stored text information is at risk of leakage because the stored area is mostly a public or shared area, and once the stored text information is leaked, the text information can be decrypted, so that the risk is high, and the security is low. In order to solve the problem, the inventor proposes a user information encryption storage and decryption recovery method in the embodiment of the invention.

and step 104, the client stores a plurality of two-dimensional code pictures in a disordered order and stores the splicing order of the segmented multiple sections of ciphertexts.
As can be known from the flow shown in fig. 1, in the embodiment of the present invention, the client encrypts the user information to obtain the ciphertext; the user information comprises user identity information and user password information; the client side divides the ciphertext to obtain a plurality of sections of divided ciphertexts; the client side respectively generates two-dimensional code pictures from each segment of the divided ciphertext to obtain a plurality of two-dimensional code pictures; the client stores a plurality of two-dimensional code pictures in a disordered order and stores the splicing order of the segmented ciphertext, so that the user information can be stored at the client, the response timeliness when the user information is read is ensured, the leakage risk of the user information is reduced, and the storage safety is improved.
