File encryption method and device and computer storage medium

Abstract

The invention discloses a file encryption method. The method includes the following steps of receiving an encryption request triggered by means of a file; according to the encryption request, selecting image elements from a preset image set and using the selected image elements for constituting an initial image set; displaying the initial image set and generating encryption prompt information to remind a user to conduct level setting; receiving a level setting instruction, obtaining an encryption level in the level setting instruction, and displaying preset textboxes the number of which corresponds to the encryption level; on the basis of a user operation, selecting target image elements in the initial image set and inputting the target image elements into the preset textboxes to form a standard code sequence corresponding to the encryption level; conducting associated storage of the standard code sequence and the file to complete the encryption operation of the file. The invention discloses a file encryption device and a computer-readable storage medium. By means of image encryption, the interestingness and convenience of encryption are improved.

Description

Technical field [0001] The present invention relates to the field of data processing, in particular to file encryption methods, devices and computer storage media. Background technique [0002] With the improvement of terminal intelligence and the increase of storage capacity, people increasingly like to store some private data in the terminal in the form of files. In order to protect the privacy of users, that is, to ensure the security of files stored in the terminal, it is extremely important to encrypt and decrypt files. [0003] The principle of file encryption in the prior art is to determine whether the user has the operation authority of the file by verifying the information input by the user. That is, most of the existing file encryption uses fingerprint encryption or digital encryption. In addition, digital encryption requires users to remember the corresponding numbers. If the set digital password is too long and complex, the decryption operations of encrypted files and...

Problems solved by technology

[0003] The principle of file encryption in the prior art is: by verifying the information input by the user to judge whether the user has the operation authority of the file, that is, most of the existing file encryption adopts fingerprint encryption or digital encryption. Monotonous. In addition, digital encryption requires users to remember the corresponding numbers. If the set digital password is too long and too complex, the decryption operation of encrypted files and folders will be more complicated, and fingerprint encryption cannot transfer files.
