In the embodiment of the present invention, a security class memory implemented by EEPROM is used to store the security class, but the technical scope of the present invention is not limited thereto. Since the security level information must be maintained even when the computer is powered off, the security level memory must be nonvolatile. Therefore, the CMOS RAM in the RTC 15, which is operated by its own battery, may be designed to be used for the above purpose, and may be replaced by a nonvolatile memory such as a flash memory. This is because the CMOS RAM and the flash memory in the ROM 14 or the RTC 15 can retain data even when the computer is powered off. In the embodiment of the present invention, the security class memory using the ROM 14, the CMOS RAM, or the flash memory is not disclosed in more detail. However, designing it from the one illustrated in FIG.

Next, referring to Figure 4 will be described the process of blocking the obscene / fallow when performing the user communication program.

First, a user computer (a personal computer including a modem or a LAN card, a network computer, a network terminal, etc.) is turned on, and an operating system is loaded into a memory. Then, a user communication program (hereinafter, communication) is controlled by the CPU 11. Program) is started (S1).

In the initialization process of the communication program, the CPU 11 reads the security level stored in the security level memory 17 by a method such as generating an interrupt, and specifies a specific position of the RAM 13 of FIG. Remember to. In addition, the modem 27 is initialized and connected to the server 37 and the modems 27 and 61 in a structure as shown in FIG. 6 (S2). In addition, as shown in Figure 7, it may be connected via the LAN (27).

Next, the communication program waits for a command from the user (S3). The command may be connected to a specific server, reception of specific information, transmission of specific information, termination, etc., but only the specific information reception command and the termination command are described herein.

When the user issues a command for receiving specific information, the communication program first sends a security level request packet to check the security level for the specific information desired by the user (S4). In FIG. 9, the location of information means information that a user wants to receive, and an appointment must be made between the communication program and the server. Promise can be done in several ways.

Next, the server 37 transmits the rating information on the information desired by the user to the communication program using the security rating packet (S5). Rating information must be made in advance and can be implemented in various ways.

Next, the communication program compares the information level received from the server 37 with the current user computer security level obtained in the initializing step (S2), and determines whether information can be received (S6).

From the determination process of step S6, if the information reception level is impossible, return to step S3 (S10), and if the security level of the computer is a level that can perform the current information program, the CPU 11 Sends the information providing request packet to the server 37 (S7).

Next, the server 37 continuously transmits the information packet to the user's communication program (S8).

Upon finally receiving the information providing end packet from the server 37, the process returns to the step S3. If the user gives an end command in this step S3, the communication program ends, and the control is transferred to the operating system.

On the other hand, external users may need to change the security level. For example, if a user of a computer changes from adolescent to adult, the security level set on the computer needs to be changed.

Next, a process controlled when the security level is changed will be described with reference to FIG. 5.

When the user inputs a predetermined specific key in the booting of the computer, execution of the security level setup program stored in the ROM 14 is started (S21). Then, a password is input through the user's key input (S22).

Subsequently, it is determined whether the password input in the step S22 matches the password preset in the security level memory 17 (S23). If the password input in step S23 matches that of the user, a new security level is input through the user's key input (S24). Otherwise, an error message is output (S25).

When the operation of step S24 or step S25 is completed, execution of the setup program is ended (S26), and the CPU 11 performs the next routine.

As described above, the computer of the present invention includes a memory for storing the security level, and controls to execute only the information program corresponding to the set security level. In addition, the security level may be changed after a user verification procedure. Accordingly, the present invention can effectively block adolescents or minors from running software containing pornographic / violent material through a computer network.
