The portable wireless transmitter 2 transmits the ID code wirelessly, and at this time, the wireless receiver 2 receives the ID code. The portable radio transmitter 2 is designed to be carried by a person, and when the portable radio transmitter is out of a certain distance, the corresponding ID code is not received. In this case, the device locks the computer's keyboard and mouse. In order to prevent the operation of the mouse and keyboard, it is a device that sends the message to the KERNEL of the OS to prevent the keyboard and the mouse from intercepting or operating the message of the keyboard and the mouse from the KERNEL of the computer OS.
In the case of Published Utility Model No. 1996-5996, the use of a keyboard is controlled by using a keyboard control connector terminal provided on a main board of a computer. The present invention is characterized in that a small wireless receiver is attached to an input / output port (USB, SERIAL, PRINT PORT, etc.) of a computer and receives a control ID code data to simultaneously control a mouse and a keyboard from a computer program.

There is a need to restrict children or teenagers from using computers too much time, such as playing games or chatting. And if necessary, sites that are considered harmful to pornography sites, violent game sites, etc. are desperately needed in the current society. However, if there is no proper response and simply relying on software, such restrictions can be easily revoked by adolescents. In the present invention, an ID code is received from a portable wireless transmitter, which is a locking device and a key device, and a hardware device is added to a device that relies only on nonsense software, and the ID code received from the wireless receiver is read and compared to match the ID code. In this case, it is possible to set the usage time and access blocking site so that the youth cannot operate it without the portable radio transmitter.

The ID code, which is an identification code of the transmitter, is transmitted by using the communication distance of the low power wireless transmitter to receive the ID code of the transmitter from the receiver. At this time, if the portable small power transmitter is out of a certain distance from the receiver attached to the computer, the receiver does not receive the ID code, which is the identification code of the transmitter. At this time, it is a device for preventing other people from operating the mouse and keyboard to prevent their computer operation. In a computer program, an ID code signal received from a wireless receiver is processed by a computer control program. This processing method is the control program technology that prevents keyboard and mouse operation from the KERNEL of the computer OS and the ID code received from the wireless receiving device (1). The USB PORT, PRINT PORT, SERIAL PORT, INTERFACE Program it so that it can be delivered anywhere in the CARD. In addition, the group code of ID code can be managed. For example, in case of small and medium-sized companies, the portable wireless transmitter ID code of the CEO or the computer system manager can be configured to operate the whole computer of the company, In this case, only the computers that are subordinate to the team can be operated, and the general practitioner can manage the group so that only his computer can operate. In the case of a computer control program, the control program should also be run when the computer OS boots. Therefore, the ID code of the portable radio transmitter cannot be operated unless the ID code authorized by the radio receiver attached to the computer is received.

In order to reduce the amount of time spent playing games, chatting, etc. with the computer for the proper use of the computer, a device that allows the user to use the computer only for a predetermined time and access control devices of sites harmful to the teenager (deafness, violence, etc.) are required. . For this purpose, a computer control program requires a time management schedule database for using a computer and a database of an internet access site. Usage management allows you to set how many hours you use the computer a day, or enter a schedule that you can set for each day of the week or month. In addition, authorize unrestricted use of programs that are beneficial to adolescents (e.g., document writing, EBS educational broadcasting sites, edunet sites, etc.), and register additional programs and sites in the database for hours of computer use. You need to select an option so that you can continue using the computer even if you over. In addition, access restriction of harmful sites for teenagers is required to register DOMAIN and IP in the database and monitor the relevant IP and DOMAIN in OS KERNEL's NETWORK protocol to prevent access to this site. And discard the packet data sent / received for the IP and DOMAIN. Therefore, nothing is seen in the browser window, and in the case of EMAIL, the effect of blocking spam of unhealthy sites is simultaneously achieved. This is because it detects DOMAIN or IP of harmful site and discards related data in OS KERNEL and computer control program. The registration deletion and modification of the time management schedule database and the harmful site database must be processed by the computer control program so that the identification code from the portable radio transmitter can be compared with the radio receiver to be TRUE. In addition, for easy registration in the database of programs and sites, it is possible to receive automatic renewal from the Internet server or to update between users through the Internet network.

When installing the control program, the super master password is input and encrypted with a special code. This supermaster password is intended for temporary use of the computer when the portable radio transmitter is broken, lost or not brought. If the user fails to enter the password within a certain time after booting the computer when the portable radio transmitter is not functioning, OS KERNEL and the control program will not operate the user computer or shut down automatically. Therefore, the computer can be used only when the computer OS is newly installed. To solve this problem, a special encryption code is created by combining the hard disk serial number, the machine code number of the network circuit, and the date (time) .Then, after decrypting using this encryption code, the user is informed of the temporary password. I need to give.

The apparatus of the present invention includes a portable wireless transmitting apparatus 2 of FIG. 1 attached to a computer, a wireless receiving apparatus 1 of FIG. 2, and a computer control program 3, and a general computer system to use this system ( 4), ID code of the user is assigned to each of the portable radio transmitters 2, and ID code of the user is also assigned to the radio receiver 1 of the computer. Further, the computer control program device 3 is programmed to encrypt and store its ID code.

In FIG. 4, the portable radio transmitter 2 transmits its ID code wirelessly at predetermined time intervals, indicating that the portable radio transmitter 2 is close to the computer system 4 from the radio receiver 1 in the own computer system 4. Inform. Receives the ID code transmitted from the wireless transmitter 2 in the wireless receiver 1 and sends it to a computer control program. At this time, the computer control program 3 compares the encrypted ID CODE with its own, and if it is the same, the mouse and keyboard can be operated to use the computer system 4. If the portable radio transmitter 2 is out of a certain distance, the radio receiver 1 cannot receive the ID code of the portable radio transmitter 2. If this ID CODE is not received for a certain period of time, the computer control program 3 determines that the user is in a non-use position of the computer, and the lock device operates to prevent the computer control program 3 from automatically using the mouse and keyboard. Done. On the contrary, when the user approaches his computer system 4, the lock is released by the operation switch (a) of FIG. 1 of the portable radio transmitter 2, or the portable radio transmitter 2 periodically at regular intervals. If you wait for that time as your ID code is sent, your computer system 4 is automatically unlocked.

In the case of FIG. 3, if the access is made to another person's portable radio transmitter 2-A, the ID code transmitted is different. Therefore, the ID code received by the radio receiver 1 is not recognized in the control program. It is supposed to be. At this time, if the user's ID code is not sent to the computer system 4 for a predetermined time, the locking device operates so that the keyboard and mouse of the computer are not operated. Therefore, it is possible to prevent the user from accessing the computer without the user permission. However, if you are accessing and operating the computer, your ID code is being received so that you can operate the computer even if someone accesses it. This is because the ID code is received by the receiver 1 because the ID code of the portable radio transmitter 2 continues to operate at a predetermined time period.

When the wireless receiver 1 is removed from the computer system 4, the ID code cannot be received, so that the locking device is automatically operated so that the mouse and keyboard of the computer cannot be operated. However, if the computer control program 3 selects the self-locking device release mode (option) while the wireless receiver 1 is attached to the computer, the wireless transmitter 2 and the wireless receiver 1 do not exist. Even if it is made by the computer control program 3 so that a mouse and a keyboard may operate, it can release a lock.

When there are several radio transmitters 1 in the same space, the radio transmitter 2 is random inside the radio transmitter 2 in order to prevent ID codes from being simultaneously transmitted wirelessly at the same time. Time generation (random numbers) is used to avoid radio transmission collisions as much as possible.

1 shows a switch (a) and (b) in a portable radio transmitter 2. Switch (a) is an unlocking switch and switch (b) is a switch for operating the locking device. In some cases, individual codes are sent to be processed by the control program so that they can be operated by this operation switch.

5 shows that in order for the intruder to operate another computer, the wireless receiver 1-A is replaced with the wireless receiver 1-A having the ID code of the intruder and the portable wireless transmitter 2 -A of the intruder. When attempting to access the computer system 4 by using the present invention, the operating configuration of the present invention is first replaced by the radio receiver 1-A of the intruder. Compare the encrypted ID code with the ID code of the intruder's wireless receiver (1-A). At this time, because the ID code is different, the locking device is activated to prevent access. At this time, the device 3 operates to generate a warning message or an alarm sound. Therefore, even if the intruder attempts to access the portable radio transmitter 2-A, it is meaningless.

The wireless receiving device, which is the device 1, receives an ID code and transmits the ID code to a computer control program through an input / output device of a computer. At this time, the input / output device of the computer can be applied to any one of the USB port, the PRINTER PORT, the SERIAL PORT, and the INTERFACE CARD, and the computer program is programmed to recognize the wireless receiving device.

The computer control program (3) device allows the operation of the mouse and the keyboard if the contents of the computer control program (3) are encrypted after the ID code is stored and compared with the function of comparing the ID code sent from the radio receiver (1). If the comparison is false, the mouse and keyboard are disabled.

The computer control program 3 operates together when the OS of the computer is started. When the ID code of the portable radio receiver 1 does not receive for a certain time, the user recognizes that the user has departed a certain distance. The computer control program (3) intercepts the OS KERNEL message for the mouse and keyboard in the computer control program (3), and then sends the mouse and keyboard message to the KERNEL of the computer OS. By sending a message to KERNEL, computer operation becomes impossible.

If the ID code of the wireless receiver 1 received from the portable radio transmitter 2 is the same as its own ID code, it is possible to operate the computer by sending a message to the KERNEL of the OS to operate normally.

For the security of the computer, the ID CODE has a double configuration. First, the function of comparing the ID CODE between the wireless receiving apparatus 1 and the computer control program 3, and secondly, the transmitting apparatus 2 and the receiving apparatus. There is a function of comparing between the devices of the device 1. If the first ID CODE is different, the computer system 4 is locked so that the mouse and keyboard cannot operate. In the second case, the ID CODE is not received for a certain time or the received ID CODE is within a certain time. If it is not the same as its ID code, the mouse and keyboard operation of the computer system 4 will be impossible. When its ID code is received in a state where computer operation is impossible, the computer system 4 automatically releases the lock to enable mouse and keyboard operation.

Fig. 6 is a flowchart for group management, in which the portable radio transmitter and receiver have their respective identification codes (ID CODE), and the control program allows the computer license ID code to be registered. For example, if the system administrator inputs the system administrator's ID code to operate the whole computer, and the team leader's ID code is registered on the computer of the relevant team, the system administrator can access any computer. In addition, the relevant team leader can only access the computer of the team.

FIG. 7 is a flowchart illustrating a method for limiting computer use time and restricting access to a site, and a function for preventing use of the computer when it is used for a predetermined time or longer and a function for not time limiting for a beneficial program or site are required. In addition, sites that are not profitable need to be blocked. The operation method in the control program will be described. This feature is commonly used at home and requires an option to operate without a portable radio transmitter, except for setting up programs for database access and control. The control program has a function to select such a function, and it is possible to determine whether or not to use the identification code of the portable radio transmitter according to the selection of the option.If the identification code of the portable radio transmitter is not required in the option selection, the computer usage time and Only those related to accessing the site will be restricted. In the case of the obscene site, it monitors the data of the computer network, and when the related sites (DOMAIN and IP) are confirmed, it sends a disconnect command signal to the other network system and discards all received data or additional network data. This operating method is determined by the setup program to allow various types of actions to be taken by the administrator.

8 is a super master password is required in case the super master password can not be transmitted due to the loss or failure of the portable radio transmitter. This function is executed by the control program (3) at the time of booting the computer. If the portable radio transmitter does not function normally, the computer cannot operate the keyboard and mouse after booting. In addition, if a recognition code is not input for some time after booting, the computer automatically shuts down. Therefore, the user will be able to use the computer only after a fresh installation of the OS of the computer. In order to prevent such inconvenience, the user can use the serial number of the hard disk of the computer, the machine number of the network circuit, the date (time), and the identification code to decrypt the data with the encrypted data according to various methods and selectively encrypt the user. Inform the user that they will be able to enter and use a temporary password for their computer. Within a certain period of time, no password is available except for the computer. For that reason, the encryption code varies depending on the first time, and the serial number of the second hard disk and the machine number of the network circuit are rarely identical with other computers. Therefore, the temporary password only applies to that computer, and after a certain time the password becomes a useless password. Thus, with a temporary password, the user may temporarily use the computer until the radio transmitter function is normalized, if the user does not use the radio transmitter according to various choices in the setup program. At this time, the super master password can be changed so that no password request is required again.

In the computer's operating system, there is a soft reset key. For example, Microsoft's operating systems, such as WINDOWS 95, 98, XP, etc., will cause a soft reset by pressing CTRL + ALT + DEL on the keyboard. At this time, if the processor of the control program belonging to a part of the present invention is stopped, there is no meaning. In order to prevent the problem of Microsoft's OS, two methods are devised and selected in the setup setting for optional use. First, when the soft reset key is input, the message of the soft reset key is transmitted to the KERNEL of the OS. In order to invalidate this forwarded message, the soft reset key input data is hooked up and requested to be discarded by KERNEL, and the control program is operated in duplicate (executing the same two programs). In this case, only one processor can be stopped when performing a soft reset and stopping the associated processor. Therefore, if duality jumps in a control program and one processor stops, a new processor (control program) is started again, and no processor interruption is caused by a soft reset. These functions allow for optional management in the control program's options. In the case of UNIX and LINUX OS, if the user logs in in the normal USER mode, the daemon is operated in ROOT mode so that the processor cannot be stopped. Therefore, the processor cannot be stopped. However, if you logged in as ROOT, you already logged in with the ROOT password, so the system must grant all functions to ROOT, so there is no need to mention soft reset and processor interruption. Therefore, this soft reset applies only to Microsoft's OS.
In order to prevent computer use time manipulation, a separate timer is configured to operate in a device attached to the computer input / output port, and the computer program is configured to receive and control the timer.

In today's information age, computers are a necessity, and most of them already use computers. Many people, including individuals and businesses, use computers, but important information about themselves or companies is contained in computers. In the modern era, the Internet has developed and most computers are connected to high-speed Internet network systems. However, if the computer contains important information or trade secrets, then the information on the computer and its secrets will be high. If you have important information or trade secrets on your computer, you may not want to be exposed to visitors or others. If your computer is a condition that others can manipulate, you can send all or some of the data on your storage device to another person's E-mail or another person's storage system via a storage device or an internet line. Will expose the information. In order to prevent this, a locking device has been developed to automatically limit the operation of the keyboard and mouse, which are essential for computer operation, by the wireless transmission / reception device. When the user moves away from the computer, the locking device automatically operates to prevent the mouse and keyboard from operating. Even if you go out for a while, the computer will not be able to operate the computer automatically. You will be protected from sensitive information or trade secrets from others.

At home, children or adolescents can't access harmful sites (fornication, violence, etc.), and spend a lot of time using computers for general games or online games and chatting. Because of the lack of self-control of adolescents, it is expected that if the device of the present invention does not allow the user to use the computer for a limited time or access the harmful site of the adolescent, it will greatly help the adolescent's proper growth and mental health.
