Embodiment approach

[0066] As an implementable manner, the encryption type is a keyboard-based encryption type, and S102 may include:

[0067] acquiring input information entered through a remote controller that matches the display device;

[0068] According to the input information, the specific character corresponding to the keyboard encryption type is determined.

[0069] The matching between the remote control and the display device means that the remote control is associated with the display device. The remote control can send control information or user information to the display device, and the display device can receive various information from the remote control. There are many methods for associating the remote control with the display device. For example, the remote control can be connected to the display device through a data cable, or the two can be associated by logging in the same account on the remote control and the display device.

[0070] The user inputs information based on t...

Abstract

The invention provides a file encryption method, a file decryption method, a storage medium and electronic equipment, and the file encryption method comprises the steps: determining an encryption typewhich comprises at least one of a fingerprint encryption type, a keyboard-based encryption type and a face encryption type; acquiring encryption information input by a user according to the encryption type, and generating a corresponding specific character according to the encryption information; and encrypting a plaintext file by using the specific character. A user can conveniently input encrypted information, and the possibility that plaintext files are illegally utilized is reduced, and the safety of the system is improved.

Description

technical field [0001] The invention relates to the technical field of cryptography, in particular to a file encryption method, a file decryption method, a storage medium and electronic equipment. Background technique [0002] Large-screen display devices are more and more commonly used in various occasions. For example, large-screen display devices are often used to set up billboards in outdoor places, and large-screen display devices are used to display documents in conference rooms. Because large-screen display devices are more commonly used in public places, various files stored on large-screen display devices are easy to fall into the hands of criminals, which brings inconvenience to the normal use of large-screen display devices by the owner of the files. Contents of the invention [0003] In order to solve the above problems, an embodiment of the present invention provides a file encryption method, a file decryption method, a storage medium, and an electronic device...
