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.
