Embodiment Construction

[0040] The mobile terminal charging anti-theft protection method provided by the present invention utilizes the pull-up characteristic of the GPIO interface, sets and reads the level status of the positive voltage data port and the negative voltage data port in the first interface through the charging detection module, thereby verifying the charging Whether the device is a suitable charger, when the verification fails, start the anti-theft module, refuse to charge and take protective measures, it is impossible to charge the mobile terminal, so that the mobile terminal can only use its original charger for charging, so as to play an anti-theft function .

[0041] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to exp...

Abstract

The invention discloses a charging anti-theft protection method for a mobile terminal. In a charger, a first triode, a second triode, a first resistor and a second resistor are arranged, and a charging detection module and an anti-theft protection module are arranged in the mobile terminal. The charging detection module is used for setting and reading level states of a positive voltage data port and a negative voltage data port in a first interface, thereby verifying whether the charger with the first and second triodes and the first and second resistors is applicable or not, and if the charger does not pass the verification, the mobile terminal enables the anti-theft protection module to deny the charging and automatically adopt the protective measures of deleting sensitive data stored in the mobile terminal, and the like. A thief cannot charge the mobile terminal even though stealing the mobile terminal, and great difficulties are brought by the worthless mobile terminal to the stolen mobile terminal disposal of the thief, so the thief naturally may not steal the mobile terminal, and an anti-theft function is naturally realized.

Description

technical field [0001] The invention relates to an anti-theft technology of a mobile terminal, in particular to an anti-theft protection technology for charging of a mobile terminal. Background technique [0002] see figure 1 , the charging system of the mobile terminal generally includes a mobile terminal 11 and a charger 21, and a central processing unit 111, a charging detection module 112 and a USB female port 113 are arranged in the charging mobile terminal 11, and the central processing unit 111 passes the charging detection The module 112 is connected with the USB female port 113 . [0003] The charger 21 has a power plug 211 , a USB data line and a USB male port. The USB data line includes a power line VDD, a positive voltage data line D+, a negative voltage data line D− and a ground line GND. A charging output module 212 is provided in the charger, and the charging output module 212 is connected to the power line VDD and the ground line GND, and the positive volta...
