Abstract
Disclosed are a high-grade privacy smart phone and a method for protecting private information of the high-grade privacy smart phone. The smart phone is composed of a radio frequency processor, a base-band processor, a first application processor, a second application processor, a display controller, a display module and the like. Wireless communication operation is carried out on the base-band processor. A first operating system in the first application processor is mainly used for processing multimedia application and the like with low privacy requirements. A second operating system in the second application processor is mainly used for processing personal issues with high privacy requirements. The first operating system and the second operating system are isolated from each other and form subsystems. Meanwhile, through hardware setting, third-party software can not be installed on the second operating system after the second operating system leaves a factory, or even, firmware upgrade can not be carried out, and therefore the second operating system becomes a closed system. According to the protection method, the first application processor and the second application processor which are independent of each other are used for processing the private personal issues and the multimedia application respectively.

Below in conjunction with the drawings and specific embodiments the present invention will be further explained explanation.
Fig. 1 is the circuit block diagram of smart mobile phone the first embodiment of the present invention, as shown in Figure 1, in the present embodiment, smart mobile phone of the present invention is comprised of six major parts such as rf processor, baseband processor, the first application processor, the second application processor, display controller and display modules.Wherein that may need during the work of two application processors, common circuit is as SIM card interface, touch-screen, keyboard/button, USB interface, bluetooth, WLAN, battery/power source management, microphone, receiver, loud speaker, earphone etc., and maybe can be built in RAM 0, the FLASH 0 in processor chips, belong to the baseband processor partial circuit, so just needn't repeat respectively to be equipped with or to switch these circuit because two application processor wheels change jobs; The multimedia application circuits such as SD card interface, broadcast receiver, camera, GPS, and maybe can be built in RAM 1, the FLASH 1 in processor chips, belong to the first application processor; Maybe can be built in RAM 2, FLASH 2 in processor chips, belong to the second application processor.
The circuit function setting of described smart mobile phone is: baseband processor is responsible for the running of radio communication, and the circuit function that realizes the hardware that two application processors are shared, is responsible for the switching of two application processor operating states, operating system simultaneously.The first operating system in the first application processor is responsible for private less demanding multimedia application, is set to wide-open system, and the user can install arbitrarily third party software as required.The second operating system in the second application processor is responsible for conversation, transmitting-receiving note, receiving and dispatching mail, Web bank, the supervisory communications record/memorandum/personal transaction device such as notepad that privacy is had relatively high expectations, can be can not the subsequent installation third party software after dispatching from the factory by hardware setting, even being set to can not firmware upgrade.The operating system of the first application processor, the second application processor forms respectively a subsystem, keeps apart each other.
The method of operation of described smart mobile phone is: described smart mobile phone, after start, can be selected or give tacit consent to enter the first operating system or the second operating system, and the system of failing to choose enters the standby resting state.When rf processor receives call signal, after the task of having relatively high expectations as privacies such as phone incoming call, note or mail reminders occurs, the running of the collaborative radio communication of rf processor and baseband processor, baseband processor switches to system or remain the second operating system automatically simultaneously, the first operating system enters into or remains the standby resting state, receives calls, receives the individual affairs such as note or mail in the second operating system.When there is no called signal, the user can freely click and enter the second operating system in the first operation system interface, calls relievedly, sends the individual affairs such as note or mail, or process the individual affair that other privacy is had relatively high expectations.Similarly, when there is no called signal, the user also can freely click and enter the first operating system in the second operation system interface, carries out the multimedia utilization, enjoys numerous functions, facility and enjoyment that smart mobile phone brings.
Like this, by described circuit setting, the second operating system that virus and Malware can't be invaded the private information place at all, also can not steal the private information that leaves the second operating system in when third party software moves in the first operating system.
Fig. 2 is the circuit block diagram of smart mobile phone the second embodiment of the present invention, and as shown in Figure 2, in the present embodiment, smart mobile phone of the present invention can also comprise the second display controller and class paper display module.Like this, when using, take multimedia application while being main the first operating system, by colored display module, to be responsible for the better demonstration task of visual performance requirement; Take above-mentioned personal transaction device while being main the second operating system when using, by class paper display module, be responsible for the less demanding demonstration task of visual performance.Its benefit is when visual performance is less demanding, or while carrying out the word read of long period, is responsible for demonstration by class paper display module, not only power saving but also vision protection, indefatigability.In the present embodiment, can between described the first operating system and described the second operating system, exchange document, to select the display mode of suitable colour or class paper.
In the present embodiment, all the other situations are identical with smart mobile phone the first embodiment of the present invention, do not repeat them here.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, the present invention can also have various modifications and variations.All change and variations within the spirit and principles in the present invention, within all should being included in claim scope of the present invention.
