Embodiment Construction

[0037] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0038] refer to figure 1 As shown, in the mobile terminal of the present invention, its memory 1 includes a read-write protected area 11 and a read-write unprotected area 12 . In addition, the mobile terminal also includes: a character string generation module 2 , a character string writing module 3 , a character string comparison module 4 , a read-write area judging module 5 and a first-time connection judging module 6 .

[0039] The character string generating module 2 is used to generate a character string by using an encryption algorithm, such as MD5, to generate the IMEI number of the mobile terminal and the MAC address of the computer connected to the mobile terminal.

[0040] The character string writing module 3 is used for writing the character string generated by the character...

Abstract

The invention discloses a mobile terminal and a data protection method thereof. The mobile terminal comprises a character string generation module used for generating a character string through an international mobile equipment identity (IMEI) number of the mobile terminal and a medium access control (MAC) address of a computer connected with the mobile terminal by an encryption algorithm; a character string write-in module used for writing the character string generated by the character string generation module in a space, invisible to a user, of the mobile terminal; a character string compare module used for judging whether the character string generated by the character string generation module is identical to a character string in the space, invisible to the user, of the mobile terminal; a read-write area judgment module used for judging whether the user should conduct read-write on a read-write protection zone or on a non-read-write protection zone; and a first connection judgment module used for judging whether the mobile terminal is connected with the computer for the first time when the mobile terminal is connected with the computer. According to the mobile terminal and the data protection method thereof, important data in the read-write protection zone of the mobile terminal can be protected practically and reliably.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a mobile terminal with data protection function and a data protection method implemented by the mobile terminal. Background technique [0002] With the continuous increase of memory capacity and the continuous decline of prices, whether it is a mobile terminal with only an internal memory or a mobile terminal with an expandable external memory, its storage capacity is constantly increasing, so users have become more and more accustomed to It is used to store your favorite songs, movies, e-books, pictures and other materials in the mobile terminal. In addition, the photo and video software in the mobile terminal will automatically store the photos and video clips taken by the user into the mobile terminal. In the memory, chat software such as MSN, QQ, etc. will also automatically store the user's chat history in the memory of the mobile terminal. [0003] Among the data stored in the ...
