Data protection method and system and mobile terminal

Abstract

The embodiment of the invention provides a data protection method and system and a mobile terminal. The method comprises the steps of data classification, data backup, state detection, state judgment, data destruction, information display and terminal alarm. The system comprises a data grading module, a data backup module, a state detection module, a state judgment module, a data destruction module, an information display module and a terminal alarm module. The mobile terminal comprises the data protection system adopting the data protection method. According to the technical scheme provided by the embodiment of the invention, important data can be quickly backed up, heavy loss is avoided, leakage of the important data is effectively avoided, secondary sales of stolen and robbed terminals can be reduced, and social stability is maintained.

Description

【Technical field】 [0001] The present invention relates to the technical field of terminal security, in particular to a data protection method, system and mobile terminal. 【Background technique】 [0002] In recent years, communication technology has developed very rapidly, especially mobile terminals are updated more and more frequently, more and more people have multiple mobile terminals, and at the same time, the storage capacity of mobile terminals is increasing, the pixels are getting higher and higher, and the mobile payment function More and more powerful, intelligent terminals can fully meet the daily needs and personalized needs of users, and the information stored in mobile terminals is becoming more and more important, involving text messages, photos, videos, bank cards, ID cards, mobile payment, etc., and other Important data, so terminal data security is becoming more and more important. [0003] At present, mobile terminals contain a large amount of address book...

Problems solved by technology

[0009] The Chinese patent with the application number CN201310023578.4 discloses a mobile communication terminal and its data protection method and system. It also does not mention the alarm function, nor does it protect and delete the data in the terminal according to the priority and importance. It is a one-time sequential deletion of all, which has the characteristics of long deletion time and poor timeliness for important data protection

[0010] It can be seen from the above four published Chinese patents that these methods can partially solve the problem of data transfer and destruction after the mobile terminal is lost, but there are still some functions to be optimized. First, most of the existing technologies send delete commands , so as to perform operation processing in the background, or preset locking command information, and send this information after it is lost, so as to lock the corresponding terminal and prevent data leakage of the mobile terminal; or send information to a specific number when changing the SIM card, and then to the new The sim card sends commands in a specific format to transfer or destroy the data in the terminal

These original methods cannot set the order of data backup and destruction in the mobile terminal according to the user's needs according to the priority and importance, cannot back up or destroy the most important data at the first time, and cannot set the mobile terminal according to the user's needs. The emergency number of the terminal is displayed, and the alarm nature information of the mobile terminal cannot be set, and a specific ring tone or other prompt tones cannot be set.
