Embodiment
Method provided by the invention is to cause important information or number to leak in order to prevent to lose because of mobile phone, makes the mobile phone can be according to specific instruction auto-destruct.The inventive method is provided with an auto-destruct device on mobile phone, behind user's lost mobile phone, utilize the number of international mobile equipment identification number as the unique identification of mobile phone, activate described auto-destruct device by sending specific short message to mobile phone, make described auto-destruct device damage the user ID card of described mobile phone and the memory of described mobile phone, thereby prevent to leak user profile.Fig. 1 is the flow chart of the inventive method, and as shown in the figure, the inventive method comprises the steps:
Of the present invention in the software of mobile phone, write specific trap, after the specific short message instruction that receives operator's transmission, mobile phone automatically performs destroys operation.
Fig. 2 is a mobile phone auto-destruct device workflow diagram of the present invention; As shown in the figure, auto-destruct work mainly comprises Virtual network operator part 20 and mobile phone operating part 21, and wherein, Virtual network operator part 20 comprises:
Whether in use step 202 judges described lost mobile phone, is then to carry out described step 204, otherwise execution in step 203;
Mobile phone operating part 21 comprises:
Whether step 212 judges described short message from operator, is execution in step 213 then, otherwise handles according to normal short message;
Fig. 3 is mobile phone auto-destruct device hardware circuit principle figure
Hardware circuit principle is described as follows:
Usually battery of mobile phone voltage is between 3.6v-4.2v, and when mobile phone normally used, the supply current of memory was no more than 30mA, and the operating current of SIM card also is no more than 30mA.By circuit theory diagrams shown in Figure 3, whether logic switch 30 is being controlled the power pack of cell voltage 31 and Flash memory 32 and SIM card 33 direct-connected.Logic imports the 301, the 302nd to 30 of logic switches by logic input 301,302 controls, two decision blocks, 212,214 logical signals that produced shown in process Fig. 2.
When two logical signals 212,214 are effective simultaneously; logic switch 30 is opened; cell voltage 31 is directly connected to Flash memory 32; and in the power supply circuits of SIM card 33; electric current can reach 200mA-400mA in short time like this; can damage Flash memory 32 and preserve the SIM card 33 of certain information content, finish the purpose of protection user profile.The mobile phone hardware circuit part damages, and can't sell once more or use.Thereby the present invention has adopted above extreme mode auto-destruct mobile phone, makes mobile phone can't use (hardware circuit damage), has reached the purpose of protection information.
In sum, the present invention utilizes the number of IME number as the unique identification of mobile phone, can be if lose by relevant certificate, send the specific short message instruction at the operator place, lost mobile phone is carried out limit operation after receiving this short message instruction, utilizes the voltage/current of battery of mobile phone, the memory (memory) of damage SIM card and mobile phone reaches the purpose that prevention information is lost.
By specific short message instruction, Automatic Program is carried out, and utilizes the voltage and current of battery of mobile phone, destroys SIM card and memory.The mobile phone existing memory all is the Flash structure, so after receiving specific instruction, at first writes the Flash flag bit, and Flash is changed to bad state, can't read with external tool.Therefore mobile phone also can't be started shooting, and can't repair; Next utilizes big current system, burns SIM card, in order to avoid the SIM card stored information is utilized.Both embedded special instruction in the mobile phone reached the destruction mobile phone by specific instruction, can't use and then the inner stored information of mobile phone can not leak.
As from the foregoing, the present invention has following characteristics:
1. protection user profile, lost handset can't sell and use once more.
2. protection IMEI resource is protected user's legitimate interests.
3. by operator, IMEI, and the mode of the special instruction of personal settings destroys, and stopped other people this destruction mode of malicious exploitation.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
