Problems solved by technology

[0003] At present, the encryption method of the mobile terminal mainly adopts the password set by the user. When encrypting or decrypting, the password can be input through the physical keyboard or virtual keyboard provided by the mobile terminal, and the password is input by handwriting on the display screen of the mobile terminal. Limited to the size of the keyboard, the size of the display screen, manual input and other factors, this conventional way of entering passwords brings inconvenience to the use of special groups of people, and thus limits the scope of use of mobile terminals

Abstract

The invention discloses an encryption and decryption device and a method based on gravity acceleration. The method of the invention comprises the following steps: detecting the motion state of a mobile terminal by a gravity accelerator; determining the concrete movement of the mobile terminal; then acquiring characters corresponding to the movement; and encrypting or decrypting the mobile terminal by using the characters as keys. Thus, the keys can be input by moving the mobile terminal to encrypt or decrypt the mobile terminal, thereby reducing the dependence of a user on a conventional password input mode and being convenient for special populations to use.

Description

technical field [0001] The present invention relates to encryption technology, in particular to an encryption and decryption device and method based on gravity acceleration. Background technique [0002] With the rapid development of mobile communication technology, mobile terminals have become an indispensable communication tool in people's daily life. In order to meet the needs of users and improve user experience, mobile terminals provide more and more functions and store more and more personal information of users. Therefore, the security of mobile terminals is very important. In order to protect the personal privacy of the user, the mobile terminal can be encrypted. [0003] At present, the encryption method of the mobile terminal mainly adopts the password set by the user. When encrypting or decrypting, the password can be input through the physical keyboard or virtual keyboard provided by the mobile terminal, and the password is input by handwriting on the display sc...
