Description

System switching method, system switching device and terminal

This application claims priority to Chinese Patent Application No. CN201510069877.0, entitled "System Switching Method, System Switching Device and Terminal", which is filed on February 10, 2015, the entire contents of which are incorporated by reference. In this application.

Technical field

The present invention relates to the field of terminal technologies, and in particular, to a system switching method, a system switching device, and a terminal.

Background technique

At present, with the development of technology, two independent systems can be operated simultaneously on one terminal, and the two systems can communicate with each other, but the two systems differ in function and security. For example, the terminal has a Personal Private Domain system (PPD system) with a lower security level and a Secure Enterprise Domain system (SED system) with a higher security level. The security domain system is secure. The security domain system of the mechanism, because the data of the user such as call, short message, schedule, recording, photography and related document data are all encrypted, the security domain system is highly secure, so the user's related privacy data is leaked. The risk is small, and the standard domain system is relatively low in terms of security performance. In addition, it can be used to switch between the security domain system and the standard domain system according to the real-time requirements of the terminal.

However, the security of the system with a higher security level in the terminal is limited. For example, a standard domain system with a lower security level and a security domain system with a higher security level are installed on the terminal, and the user bound to the terminal is in the security domain system. When the terminal is used, for some reason, the user bound to the terminal leaves the terminal, and the terminal not only does not go out of the screen but also runs in the security domain system. At this time, if other users use the terminal, the data in the security domain system is easy. Leaked, reducing the user experience.

Therefore, when a user bound to a terminal leaves the terminal, how to avoid leakage of data in a system with a higher security level in the terminal becomes an urgent problem to be solved.

Summary of the invention

The present invention is based on the above problems, and proposes a new technical solution. When a user bound to a terminal leaves the terminal, the terminal can be automatically switched to a system with a lower security level, thereby avoiding a higher security level of other users. Data in a system or a system with a higher security level, thereby preventing data in a system with a higher security level from being illegally leaked, thereby improving the security performance of the terminal.

In view of this, an aspect of the present invention provides a system switching method for a terminal, where a plurality of systems are installed, the method includes: determining whether a terminal operating in the current system detects the first identity. Information, when the determination result is no, controlling the terminal to be switched by the current system to the target system; otherwise, controlling the terminal to continue to run in the current system; wherein the first identification information is The identification information of the user bound to the terminal, the target system being any other system whose security level is lower than the security level of the current system.

In this technical solution, a terminal installed with multiple systems runs in a current system with a higher security level. When the first identity information pre-stored in the terminal is detected, it indicates that the user bound to the terminal is using the terminal when not detected. When the first identity information pre-stored in the terminal indicates that the user bound to the terminal has left the terminal, the control terminal switches from the current system with a higher security level to the target system with a lower security level, thereby preventing the illegal user from using the security level.

Determining whether the terminal running in the current system detects the first identification information, and when the determination result is no, controlling the terminal to switch from the current system to the target system; otherwise, controlling the terminal to continue to run in the current system The first identification information is identity identification information of a user bound to the terminal, and the target system is any other system whose security level is lower than the security level of the current system.
The terminal according to claim 11, wherein the processor further performs the following operations before controlling the terminal to switch from the current system to the target system:

When it is determined that the terminal does not detect the first identity identification information, determine whether the terminal is off, and if the determination result is no, control the terminal to switch from the current system to the target system; When yes, the terminal is controlled to maintain the current operating state.
The terminal according to claim 11, wherein the processor further performs the following operations:

After the terminal switches to the target system, if the terminal re-detects the second identity identification information, it is determined whether the second identity identification information matches the first identity identification information, and according to the determination result Determining whether the terminal is directly switchable to the current system by the target system.
The terminal according to claim 13, wherein the processor determines, according to the determination result, whether the terminal can be directly switched to the current system by the target system, and specifically includes:

When the determination result is yes, if the terminal receives a handover command that is switched by the target system to the current system, the terminal is controlled to be directly switched by the target system to the current system;

When the determination result is no, if the terminal receives the handover command that is switched by the target system to the current system, prompting the current user to input the system handover key, and when the system switching key is correct, controlling The terminal is handed over to the current system by the target system, otherwise the terminal is prohibited from being switched by the target system to the current system.
The terminal according to any one of claims 11 to 14, wherein the first identity identification information and the second identity identification information comprise: voice information of a user and a face bound to the terminal At least one of feature information, body impedance information, human body infrared information, finger pressure information, and hand feature information.
