It should be noted that although this embodiment is exemplified by setting the encryption setting in the first operating system, the same method may be used in setting the encryption setting in the second operating system, and no further description is provided herein.

First, in step S201, the first operating system should be executed. The flow 200A executed by the first operating system 110 includes steps S202 and S204 in the setting phase. In step S202, the first operating system 110 accepts the encryption settings set by the user. In short, the so-called encryption setting is the user account and password set in response to various encryption requirements. For example, the encrypted object may be the entire system usage right, the network login authority, or the usage rights of various peripheral devices, and various encryption objects are within the scope of application of the present invention. After step S202, the present invention performs a special step S204. In step S204, the system state is that the first operating system 110 under the first operating system 110 will record a system encryption status value in the controller 130 through an interface (eg, the Windows operating system will pass through the WMI interface). The system encryption state value is used to indicate that the account password is set under the operating system. For convenience of description, in the embodiment, the account password is set under the first operating system 110. In a preferred embodiment, the system encryption status value should be recorded in the controller 130 for access by the various operating systems 110 and 120. Thereafter, in step S206, the first operating system 110 receives the command of the user to switch the operating system (for example, the user presses a specified keyboard button or a hot key, or operates a specific user interface in the screen). The component controls the control of the electronic device 100 from the first operating system 110 to the second operating system 120, and enters a Hibernate mode in step S208.

The controller 130 receives an instruction to switch to the second operating system 120 Thereafter, the second operating system is started (step S206), and the second operating system 120 will request the controller 130 to switch the control of the peripheral device 140 to the second operating system 120, and the system state will be changed to the second operating system. . Thereafter, when the second operating system 120 wants to enter the standby (Standby/Sleep) mode under some conditions (for example, pressing the power button) (step S210), the aforementioned system encryption state value stored in the controller 130 is checked in step S212. In order to know whether the aforementioned encryption setting has been set by the first operating system 110. If not, the second operating system 120 directly enters the standby mode. If so, the control of the peripheral device 140 is switched to the first operating system 110 (step S214), and then the standby mode is entered as in step 218.

After this time, when the user operates a specific action (for example, pressing the power button again) to wake up the computer system, the first operating system 110 will be woken up (step S214), after which the first operating system 110 displays in step S216. An input interface for the user to input the account password required for decryption. When the user correctly enters the account password, in step S219, if the current system status confirmation is still the second operating system 120, then in step S220 Once again, the control right of the electronic device 100 is switched back to the second operating system 120 by the first operating system 110, and the second operating system 120 is awakened (step S221), so that the system is still in the use environment of the second operating system 120, and An operating system 110 itself enters the sleep mode again (step S222). Through the design of the foregoing system encryption state value and the temporary switching mechanism of the present invention, the present invention can completely manage the relevant encryption settings of the same encryption object to be managed by a single operating system, thereby avoiding the confusion caused by the repeated encryption of the prior art and improving the use. Convenience.
