Method and apparatus for managing module use of multi-user based device

A method performed on an electronic device, the method comprising:

• executing an operating system (OS) in a first state in which a first application program is capable of using at least one of a hardware component and a software module;
• permitting a second application program to use the at least one of the hardware component and the software module in the first state in response to a first input requesting execution of a function of the second application program, which is set to be executed in a second state of the OS, the second state being different from the first state;
• and
• preventing a third application program from using the at least one of the hardware component and the software module in the first state in response to a second input requesting execution of a function of the third application program, which is set to be executed in a third state of the OS, the third state being different from the both the first state and the second state.

A computer recording medium recorded with a computer-readable instruction, the instruction, which is executed by at least one processor, causing the processor to perform a method, the method comprising:

• executing an operating system (OS) in a first state in which a first application program uses at least one of a hardware component and a software module;
• permitting a second application program to use the at least one of the hardware component and the software module in the first state in response to a first input requesting execution of a function of the second application program, which is set to be executed in a second state of the OS, the second state being different from the first state;
• and
• preventing a third application program from using the at least one of the hardware component and the at least one software module in the first state in response to a second input requesting execution of a function of the third application program, which is set to be executed in a third state, the third state being different from both the first state and the second state.

A method for managing access to a module of an electronic device, the method comprising:

• receiving a request to access the module from a user or an application executed by the user;
• determine whether an identifier (ID) of the user matches a main user ID of the electronic device;
• permit access to the module, when the ID of the user matches the main user ID;
• determine whether to permit access to the module based on at least one of an access policy and user information, when the ID does not match the main user ID.
