Terminal encryption and decryption method and terminal

Abstract

The invention provides a terminal encryption and decryption method, which is applied in a terminal with a displacement sensing device, and comprises the following steps of step 102, utilizing the displacement sensing device to acquire a first moving track of the terminal in space, and generating encryption track information; step 104, utilizing the encryption track information to encrypt an application module or file required to be encrypted; step 106, utilizing the displacement sensing device to acquire a second moving track of the terminal in space, and generating decryption track information; and step 108, comparing the decryption track information with the encryption track information, and if the decryption track information is matched with the encryption track information, decrypting the application module or file. Correspondingly, the invention also provides the terminal. Through the technical scheme of the invention, a secret key is set according to the preferences of users, an encryption function is more concealed, and the information can be effectively prevented from being revealed.

Description

Technical field [0001] The present invention relates to encryption technology, in particular, to a terminal encryption and decryption method and a terminal. Background technique [0002] In related technologies, the terminal encryption technologies used include the following: The first is to use character encryption methods. When a certain function (such as power-on, address book, SMS, etc.) is in an encrypted state and needs to be decrypted, a pop-up request will appear. The prompt interface for entering the password can only accept the keyboard to enter the character password; the second type, the pattern solution, such as the pattern encryption that comes with Android, the screen has n points in a fixed position, and several of them are connected into a certain shape as the key ; The third is to use the existing face and fingerprint encryption technology on the PC for encryption. However, for the above encryption methods, there are still some shortcomings, such as a very obvi...

AI Technical Summary

Problems solved by technology

However, there are still some defects in the above encryption methods, such as a very obvious reminder whether a certain function has been encrypted. At the same time, the password is generally a number or other characters, which is easy to forget and easy to crack through repeated attempts.
