Abstract

According to one embodiment, an electronic device includes storage including an operating system (OS) and circuitry. The circuitry executes the OS capable of creating a first user account and a second user account. The OS comprises a first function for prohibiting, according to a first setting, first functions of the OS out of functions available to the first user account while user has logged in to the second user account. The OS further comprises a second function for prohibiting, according to a second setting, second functions of the OS. One of the second functions coincides with one of the first functions. The first function is prohibited from being active while the second function is active or the second function is prohibited from being active while the first function is active.

Claims

1. An electronic device comprising:

storage comprising an operating system

circuitry configured to execute the operating system capable of creating a first user account and a second user account, wherein

the operating system comprises a first restriction function for prohibiting, according to a first setting, first functions of the operating system out of functions available to the first user account while user has logged in to the second user account,

the operating system further comprises a second restriction function for prohibiting, according to a second setting, second functions of the operating system,

one of the second functions coincides with one of the first functions, and

the first restriction function is prohibited from being active while the second restriction function is active or the second restriction function is prohibited from being active while the first restriction function is active.

2. The device of claim 1, wherein the first setting is created by a user through a user interface, and the second setting is received from a server.

3. The device of claim 1, wherein at least one of switching to the second user account and newly creating the second user account is prohibited on the second restriction function being active.

4. The device of claim 1, wherein, when a first component for obtaining the second setting is installed from a server and a second component for performing the second restriction function is not installed, the circuitry installs the second component.

5. The device of claim 1, wherein the first restriction function is permitted:

to be active even though the second restriction function is active as long as the second setting includes information on permission to create the second user account;

to log in using the second user account;

or to switch to the second user account.

6. A control method of an electronic device having storage comprising an operating system and circuitry executing the operating system capable of creating a first user account and a second user account, wherein

the operating system comprises a first restriction function for prohibiting, according to a first setting, first functions of the operating system out of functions available to the first user account while the user has logged in to the second user account, and

the operating system further comprises a second restriction function for prohibiting, according to a second setting, second functions of the operating system one of the second functions coincides with one of the first functions,

the method comprising:

prohibiting the first restriction function from being active while the second restriction function is active or the method prohibits the second restriction function from being active while the first restriction function is active.

7. The method of claim 6, wherein the first setting is created by the first user through a user interface, and the second setting is received from a server.

8. The method of claim 6, wherein at least one of switching to the second user account and newly creating the second user account is prohibited on the second restriction function being active.

9. The method of claim 6, wherein, in a case where a first component for obtaining the second setting is installed from a server whereas a second component for performing the second restriction function is not installed, the second component is installed.

10. The method of claim 6, wherein the first restriction function is permitted to be active even though the second restriction function is active as long as the second setting includes information on permission to create the second user account, to log in using the second user account, or to switch to the second user account.

11. A computer readable, non transitory storage medium configured to store a computer program which is executable by a computer, the computer program capable of creating a first user account and a second user account, and controlling the computer to execute functions of:

processing a first restriction function of prohibiting, according to a first setting, first functions of the operating system out of functions available to the first user account while a user has logged in to the second user account;

processing a second restriction function for prohibiting, according to a second setting, second functions of the operating system, one of the second functions coinciding with one of the first functions; and

prohibiting the first restriction function from being active while the second restriction function is active or prohibiting the second restriction function from being active while the first restriction function is active.

12. The medium of claim 11, wherein the first setting is created by the user through a user interface, and the second setting is received from a server.

13. The medium of claim 11, the computer program further controlling the computer to execute function of:

upon the second restriction function being active, to prohibit at least one of switching to the second user account and newly creating the second user account.

14. The medium of claim 11, the computer program further controlling the computer to execute function of:

permitting the first restriction function to be active, even though the second restriction function is active, as long as the second setting includes information on permission to create the second user account, to log in using the second user account, or to switch to the second user account.
