File encryption method based on two-dimension code scanning

Abstract

The invention discloses a file encryption method based on two-dimension code scanning. The file encryption method comprises the steps that a safe file box storing a plurality of files is installed on a PC, a two-dimension code for encryption of the safe file box is generated based on a user name, current time, a random value and the overall unique identification GUID of the PC, the user name and a user password are used as a log-on message and are stored on an authentication server, when a user name and a user password for logging onto an APP of a mobile terminal are identical to the user name and the user password of the log-on message respectively, a user is authorized to successfully log onto the APP of the mobile terminal, the APP of the mobile terminal scans the two-dimension code and sends the scanned two-dimension code to the authentication server, the authentication server analyzes the scanned two-dimension code to obtain the user name, and when the user name obtained through analysis is identical to the user name of the log-on message, the user is authorized to access the files stored in the safe file box. According to the file encryption method, the PC and the mobile terminal are coordinated, the user is authorized to access the files stored in the safe file box of the PC based on two-dimension code scanning, and therefore the password for file encryption is prevented from being forgotten or stolen.

Description

technical field [0001] The invention relates to the field of file encryption, in particular to a file encryption method based on two-dimensional code scanning. Background technique [0002] With the development of science and technology and the progress of society, electronic office has become the mainstream office mode. In electronic office, files are the main carrier of information, and people communicate and help each other through files. For some confidential documents, it is often expected that only a small number of authorized users can open and obtain information. The leakage of confidential document information will make the leakage faster and spread faster, thus bringing unnecessary losses to the electronic office units. [0003] In the prior art, no good file confidentiality technology is provided. A popular electronic file encryption method is to authorize users to set static password files or encrypt folders. However, in this way, authorized users tend to forget...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the technical problem that the existing static password file encryption method is easy to forget and steal the password, the present invention provides a file encryption method based on two-dimensional code scanning, which transforms the original file encryption method and utilizes PC and mobile The information interaction between the mobile terminal and the authentication server realizes the access authorization to the secure file box that stores multiple files, during which the authorized user name is authenticated multiple times on the mobile terminal and the authentication server, which improves the reliability of electronic file encryption
