Computer system having a function for intercepting lewd/violent programs and method for controlling access of such lewd/violent programs
First Claim
1. A computer system, comprising:
- a first memory device for storing an initialization program and a security grade setup program;
a second memory device for storing a security grade which is a program classification code selected by a user for designating an unacceptable program content contained in an application program, and a password for identifying the user when changing the security grade; and
a controller for controlling execution of an application program according to the security grade of the application program and the security grade stored in said second memory device during operation of said initialization program, and for controlling the changing of the security grade stored in said second memory device during operation of said security grade setup program, when the user inputs a password that corresponds to the password stored in said second memory device.

Abstract
A computer system having a function of interrupting lewd/violent programs which includes a read-only-memory for storing an initialization program and a security grade setup program; a non-volatile memory device for storing a security grade which is a program classification code selected by a user for designating an unacceptable program content contained in an application program, and a password for identifying the user when changing the security grade; and a controller for controlling execution of an application program according to the security grade of the application program and the security grade stored in the non-volatile memory device during initialization, and for controlling the changing of the security grade stored in the non-volatile memory device during the security grade setup, when the user inputs a password that corresponds to the password stored in the non-volatile memory device. As a result, the computer system is able to limit access to application programs that contain unacceptable levels of graphic sex, violence, and strong language.

5. A method for controlling a computer system having a function of interrupting lewd/violent programs, said method comprising the steps of:
-
receiving an application program in the computer system; comparing a security grade contained in an application program with a security grade set in the computer system when the application program is executed; detennining whether the security grade set in the computer system enables execution of the application program; executing the application program when the security grade set in the computer system enables execution of the application program; and alternatively, providing a visual display of an error message indicating that the application program cannot be executed, when the security grade set in the computer system does not enable execution of the application program. - View Dependent Claims (6, 7, 8)

9. A computer system, comprising:
-
a central processing unit; a first memory for loading a program executed by the central processing unit; a second memory for storing an initialization program and a security grade setup program; a security grade memory device for storing a security grade which is a program classification code selected by a user for designating an unacceptable program content contained in an application program, and a password for identifying the user when changing the security grade; a plurality of peripheral device controllers for driving operation of a plurality of peripheral devices including a display device, a keyboard, a printer, a hard disk drive and a compact-disk read-only-memory drive; and said central processing unit controlling execution of an application program according to the security grade of an application program and the security grade stored in said security grade memory device during initialization, and for controlling the changing of the security grade stored in said security grade memory device during said security grade setup, when the user inputs a password that corresponds to the password stored in said security grade memory device. - View Dependent Claims (10, 11, 12, 13)
