Problems solved by technology

However, limited by the hardware performance of the current mobile phone and other conditions, data encryption / decryption on the current mobile phone will consume and occupy various hardware resources on the mobile phone
For the encryption / decryption of larger files or the use of advanced encryption / decryption algorithms with high complexity, it will take more time
At the same time, due to resource occupation during encryption / decryption, it is difficult for users to perform other effective operations, which affects user experience
At present, there is no automatic encryption / decryption method for data in the standby state of the mobile phone

Embodiment Construction

[0028] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0029] The method of the present invention is characterized in that:

[0030] The main modules involved in the method include: a monitoring module and an encryption / decryption module. After the system is initialized, the user sets the lower limit of the battery power of the mobile phone P T And the upper limit of memory usage O M . The monitoring module mainly monitors the following content: the current power P C Is it less than the lower limit of power P T ;Current memory usage O C Is it greater than the upper limit of memory usage O M ;Whether the phone is currently in standby mode. The encryption / decryption module is mainly responsible for encrypting / decrypting files according to the encryption / decryption algorithm selected by the user, and will generate relevant temporary encryption / decryption files during the encryption / decryption process.

Abstract

The invention provides a data automatic encryption / decryption method in a standby state of a cellphone. According to the method, spare resources in the standby state of the cellphone are employed, and automatic encryption / decryption of to-be-encrypted / decrypted data selected by users in advance is performed. In the process for executing encryption and decryption, the encryption process can be automatically controlled according to the current standby state, current electric quantity, and current memory occupancy rate of the cellphone, the operation frequency and waiting time for the users are reduced, and the influence on the usage of user equipment in the encryption / decryption process is reduced.

Description

(1) Technical field [0001] The invention relates to the field of mobile terminal data security, in particular to a data automatic encryption / decryption method in an android mobile phone standby state. (2) Background technology [0002] As mobile terminal users pay more and more attention to terminal data privacy, most users need to encrypt / decrypt data in advance before transferring or backing up files. However, limited by the hardware performance and other conditions of the current mobile phone, data encryption / decryption on the current mobile phone terminal will consume and occupy various hardware resources on the mobile phone. For the encryption / decryption of larger files or the use of advanced encryption / decryption algorithms with high complexity, it will take more time. At the same time, due to resource occupation during the encryption / decryption period, it is difficult for the user to perform other effective operations, which affects the user experience. At present, ...
