<Embodiment 1>
<Overview>
As shown in FIG. 1, the computer lock system includes a computer main body 0100 and a receiving interface device 0101 externally connected to the computer main body 0100. For example, a user who is logged in to the computer and is working (FIG. 1, left figure). ) Automatically locks the computer interface (display interface, etc.) when leaving the seat (Fig. 1, right figure), and when the user returns to the seat and approaches, the receiving antenna device 0101 receives the antenna signal. It constitutes a system that automatically unlocks when the included unlock ID is received. FIG. 1 shows a display 0102 and a keyboard 0103 that the user is using during work as other hardware. The display screen in the left figure of FIG. 1 shows a screen during work, and the display screen in the right figure of FIG. 1 shows a computer lock screen. Further, the unlock ID may use the uninterruptible RFID possessed by the user.

<Embodiment 1 Configuration>
As shown in FIG. 2, the computer lock system of the first embodiment is a computer lock system including a computer main body 0200 and a receiving antenna device 0210, and the receiving antenna device 0210 includes an antenna signal receiving unit 0211 and an antenna signal. The computer main body 0200 includes an output unit 0212, an antenna signal acquisition unit 0201, a judgment unit 0202, an available status information holding unit 0203, an enabled unit 0204, an disabled unit 0205, and a control unit. It has 0206 and.

<Explanation of Embodiment 1 Configuration>
<Embodiment 1 Receiving Antenna Device>
The "receiver antenna device" 0210 is externally connected to the computer main body 0200, and the user who is logged in to the computer is present at the office or the like to work (Fig. 1, left figure), and leaves the seat during the work (Fig. 1, left figure). (Fig. 1, right figure), if the user moves beyond the effective communication range with the receiving antenna device, communication with the user who owns the unlock ID becomes impossible, and the computer is automatically locked. That is, the lock screen is displayed while the player is away from the desk as shown in the right figure of FIG. The next time the user approaches or returns to the seat, that is, within the effective communication range of the receiving antenna device, the unlock ID owned by the user (for example, built into the card or wireless tag possessed by the user). It has a function of receiving an antenna signal including () and passing an unlock ID for unlocking the computer from an unusable state by locking the computer from the received antenna signals to the computer body. It is preferable to output an ID for the computer connected to the receiving antenna device to recognize itself from the antenna signal output unit of the receiving antenna device.

<Embodiment 1 Antenna signal receiver>
The "antenna signal receiving unit" 0111 wirelessly receives an antenna signal that may include noise and no signal. Uninterruptible RFID, short-range wireless communication, etc. can be used as the wireless antenna signal. The received antenna signal includes noise and no signal, and also includes the unlock ID described above.

<Embodiment 1 Antenna signal output unit>
The "antenna signal output unit" 0212 outputs the received antenna signal to the computer main body 0200. The output of the antenna signal output unit 0212 is input to the antenna signal acquisition unit 0201 of the computer main body 0200. The antenna signal may or may not include an unlock ID. The ID to be recognized by the connected computer may be output from the antenna signal output unit.

<Example 1 Computer body>
The "computer body" 0200 corresponds to a computer, a notebook PC, a tablet PC, etc., and the display may be a display separate from the computer, or may be a lock of a display interface integrated with the PC. As for computer work, in an environment where multiple users such as companies, city halls, and public institutions are working, the system locks the computer without any settings even if you leave your seat during work. There is. Also, when returning to the seat, the computer is unlocked when the unlock ID possessed by the user is included in the antenna signal via the receiving antenna device 0210 externally connected to the computer main body 0200. can do. Here, the effective communication range (effective communication range) between the receiving antenna device externally connected to the computer body and the user (who possesses the unlock ID) is set in the range of 1 to 2 meters. It is convenient that the receiving antenna device is configured so that the effective communication range (effective communication range) can be changed by operating from the connected computer main body. When the transmission is used for receiving the unlock ID, the transmission strength may be increased or decreased, and when the transmission is received, the reception sensitivity may be adjusted. For example, when the installation interval of the computer is as narrow as less than 1 meter, the effective communication range (effective communication range) may be set to 1 meter or less.
<Embodiment 1 Antenna signal acquisition unit>
The "antenna signal acquisition unit" 0201 acquires the antenna signal output from the antenna signal output unit 0212. The antenna signal acquisition unit 0201 acquires an antenna signal and a non-antenna signal as shown in FIG. 3 described later.

<Embodiment 1 Judgment Unit>
The "judgment unit" 0202 includes the antenna signal from the antenna signal acquisition unit 0201 or does not include the antenna signal from the antenna signal acquisition unit 0201 (non-antenna signal). The display interface of the computer main body 0200 is added to the acquisition unit signal. It is intermittently determined whether or not the unlock ID, which is an ID for making it normally available, is included.

As shown in FIG. 3, the above-mentioned acquisition unit signal includes an antenna signal and a non-antenna signal that does not include the antenna signal. The form of the acquisition unit signal may be only the antenna signal (A) or only the non-antenna signal (B). In the case of only the antenna signal (A), there are cases where only the unlock ID (A-1) is included, and there are cases where the unlock ID (A-1) and other signals (A-2) are included. When both the antenna signal (A) and the non-antenna signal (B) are included, only the unlock ID (A-1), the unlock ID, and other signals (A-1, A-2) are included. May be included.
The unlocking ID of the antenna signal (A) and other signals include an acquisition unit ID with an antenna ID. Further, the non-antenna signal includes an acquisition unit ID without an antenna ID.
Here, the non-antenna signal also includes a weak current generated at the receiving antenna insertion port of the computer main body, such as when the receiving antenna device is not connected. Therefore, each unit that utilizes the determination unit or the determination result in the determination unit is configured so that the acquisition signal does not include the antenna ID and continues to function even if it is determined that a part of the computer lock system is malfunctioning. Other signals of the antenna signal include a parameter changeable key for changing parameters of each part such as a judgment unit, an enablement status holding unit, an enablement unit, an unavailability unit, and a control unit. It may be configured as follows. It is conceivable that the judgment unit is also responsible for determining whether or not the parameter change enablement key is included, and the parameters of each part can be changed from the interface of the computer itself. The unlock ID can be mentioned as a parameter of the judgment unit, and the status itself, the validity period of the available status, the history accumulation period of the available status, etc. can be mentioned as the parameter of the available status holding unit. As the parameters of the enablement unit and the unavailability unit, when there are a plurality of available status holding units, which of the available status holding units is to be the available status or the unavailable status can be mentioned. When there are multiple available status holders, when there are multiple logged-in users registered in the OS (available files, available databases, available external connection devices, available networks, etc. depending on the logged-in user). Available applications are different). In this case, if Mr. A's unlock ID is acquired, the user can log in to Mr. A and use the computer normally, but use it so as not to affect the login of other users. Will be done. The parameter of the control unit is a case where the type of display interface to be controlled is selected. For example, if multiple displays are connected to one computer, configure all displays to be able to operate normally, or only some displays can be operated normally. This is a case where you can choose whether to configure it. It is also possible to configure the display interface to be controlled differently according to the time and time.

Since the determination unit 0202 intermittently determines the antenna signal and the non-antenna signal based on such an acquisition unit signal, even if the receiving antenna device externally connected to the computer body is removed, it is not affected. The computer can be locked and unlocked based on the acquisition signal.

For example, if the computer is locked and the display interface is unavailable, the determination unit 0202 determines that the unlock ID is included, and the enablement unit 0204 uses the available status information holding unit 0203. The possible status information is set to the available status, and the computer is unlocked under the control of the control unit 0206. At this time, if the unlock ID is not included, the computer is maintained in the locked state. It is desirable that the operation of this determination unit be performed intermittently. The intermittent time interval is selected according to the work content, but for normal work, it may be set to a time of several seconds to several tens of seconds. The computer itself may be provided with a time interval adjusting unit for adjusting an intermittent time interval.

<Embodiment 1 Available status information holding unit>
“Available status information holding unit” 0203 holds available status information indicating whether or not the display interface of the computer main body 0200 determined based on the acquisition unit signal is in a normally usable state. The state in which the display interface can be normally used means a state in which data can be input or work instructions can be given using the mouse cursor using a keyboard or mouse connected to the computer. However, since the cursor movement and key operations for entering the password on the lock screen are designed to be possible even in the locked state, the state in which this operation is possible is not called the normally usable state.

<Embodiment 1 Availability Department>
When the determination result of the determination unit 0202 includes a valid release ID, the "availability unit" 0204 displays the available status information of the available status information holding unit 0205 to the display interface of the computer main unit 0200. Is the available status to make it normally available.

<Embodiment 1 Unavailability Unit>
If the determination result of the determination unit 0202 does not include a valid release ID, the "unusable unit" 0205 displays the available status information of the available status information holding unit 0203 on the display of the computer main unit 0200. An unavailable status for the interface to render the display normally unavailable.

<Embodiment 1 Control Unit>
The "control unit" 0206 controls the display interface based on the available status information held in the available status information holding unit 0203. The control unit 0206 controls the display interface to be normally available if the available status information is available. If the available status information is unavailable, the display interface is normally unavailable. The lock screen is a screen that accepts password input and is configured to be unlockable, but is not normally available. This is because it is not possible to immediately start normal work while the display interface has only a password reception function. However, the lock screen is not limited to this, and may be configured to be a screen state that does not accept password input. In that case, it is configured so that it does not accept mouse input, keyboard input, or cursor input.

In the computer lock system as described above, the receiving antenna device 0210 is detachably connected to the computer body 0200, and even if the receiving antenna device 0210 is removed from the computer body during the computer lock, the computer body 0200 is described above. Since the antenna signal and the non-antenna signal are determined based on the acquisition unit signal as described above, safety can be maintained. That is, the receiving antenna device is not affected by being removed from the computer body or not being removed, and safety can be maintained.

Moreover, even if the receiving antenna device is replaced with another antenna receiving device, it cannot be used by a third party.

<Embodiment 1 Action: Hardware configuration (computer body)>
As shown in FIG. 4, the configuration of the computer of the computer main body includes a CPU 401, a non-volatile memory 0402 such as an HDD and a ROM, a main memory 0403 such as a D-RAM, and an interface 0404. The non-volatile memory 0402 stores programs such as an antenna signal acquisition program, a determination program, an available status information holding program, an enablement program, an unavailability program, and a control program. The data includes an antenna signal, an unlock ID, available status information, and the like. These programs and data are read into the holding area of the main memory 0403 and executed in the work area. Further, the interface 0404 includes a display interface 0405, a keyboard interface 0406, a network interface 0407, and the like.

<Example 1 Process flow Receiving antenna device>
As shown in the right figure of FIG. 5, the operation of the receiving antenna device executes an antenna signal receiving step of wirelessly receiving an antenna signal including noise and no signal by the antenna receiving program (step 0501). This antenna signal is, for example, a signal from an uninterruptible RFID or the like. It is determined on the computer body side whether the unlock ID is included.

Next, the antenna signal output step of outputting the antenna signal received by the antenna signal output program to the computer main body is executed (step 0502). By this process, the antenna signal is input to the externally connected computer body.

<Implementation 1 Processing flow Computer body>
As shown in the left figure of FIG. 5, the operation of the computer of the computer body as described above is an antenna signal acquisition step for acquiring the antenna signal output from the antenna signal output unit 0212 of the receiving antenna device by the antenna signal acquisition program. Is executed (step 503).

Next, the determination program makes the display interface of the computer body normally available for the acquisition unit signal, which is a signal including the antenna signal in the antenna signal acquisition step 0503 or not including the antenna signal in the antenna signal acquisition step. The determination step of intermittently determining whether the unlock ID, which is the ID for the computer, is included is executed (step 0504). Here, the intermittent determination operation is set in about several seconds to several tens of seconds in normal work.

Next, if the judgment result in the judgment step 0504 by the enablement program is a judgment result including a valid release ID, the display interface of the computer body normally displays the available status information of the available status information holding unit. Execute the enablement step of making the available status to make it available (step 0505).

Here, the available status information indicating whether or not the display interface of the computer main body determined based on the acquisition unit signal by the available status information holding program is in a normally usable state is always held. Therefore, the availability step changes and retains the availability status. Further, the unlock ID and the login user information of the corresponding computer body are held in association with each other. If you have multiple computers, you can set the login unlock ID individually, but in an environment where the computers are used in the shared settings, you can use one unlock ID for each other or use each of them. Multiple unlock IDs can be set. Further, it is desirable to set another unlock ID so that the user in charge of the computer can be used even if the user in charge of the computer is absent in a company or a public institution.

Next, if the judgment result in the judgment step 0504 does not include a valid release ID, the available status information of the available status information holding step is displayed by the display interface of the computer main body 0200. The disabling step of making the status unusable to make it unusable is executed (step 0506).

Here, if it is not an unlock ID, it means that the locked state is continuously maintained when it is in the locked state, and security measures can be taken for a computer that is not associated with the computer itself. Therefore, the display interface cannot be used as it is. These unavailable status information is held in the available status information holding unit.

Next, a control step of controlling the display interface based on the available status information held by the available status information holding unit by the control program is executed (step 0507).

If the user does not end the use of the computer (step 0508), the process described above is returned to the antenna signal acquisition step and repeated. Further, when the use of the computer is terminated (step 0508), for example, when the power of the computer is turned off, the process is terminated.
When the computer is turned on again, the computer lock system is started, and the lock state and unlock state are automatically changed based on the unlock ID and user status information assigned to the computer without any user operation. Is controlled.

As described above, according to the first embodiment, in the computer lock system including the computer main body and the receiving antenna device externally connected to the computer main body, a computer lock system that can maintain safety even if the receiving antenna device is removed is provided. Can be provided.

It is configured.

<Explanation of Embodiment 3 Configuration / Action>
Since the description of the configuration and operation of the third embodiment has been described in detail in the description of the case (CASE) 2 of FIG. 6 of the second embodiment, the description thereof will be omitted.

In the third embodiment, since the receiving antenna device 0210 externally connected to the computer main body 0200 is supplied with power from the antenna signal acquisition 0201 of the computer 0200, the receiving antenna device does not have an OFF switch. That is, the receiving antenna device does not have a function of turning off the power by itself.

In the example of the third embodiment described above, the receiving antenna device does not have a power supply, but when the computer main body is battery-powered by a laptop computer or when a small tablet is used, reception is performed when the power supply capacity is insufficient. A configuration in which an external power source is supplied to the antenna device may be adopted, or a battery or a rechargeable secondary battery such as a lithium ion battery or a nickel hydrogen battery may be used inside.

As described above, according to the third embodiment, in addition to the first embodiment or the second embodiment, power is always supplied when the receiving antenna device is connected to the computer main body, so that the antenna signal of the receiving antenna device is supplied. Since the receiving unit and the antenna signal output unit are always in the operating state, the computer is continuously locked and unlocked.

<Embodiment 4>
<Overview>
The fourth embodiment is a computer lock system based on the first to third embodiments and having some features. The fourth embodiment is characterized in that it has a competition adjustment function between the screen saver and the computer lock system.

<Structure of Embodiment 4>
As shown in FIG. 7, the computer lock system of the fourth embodiment is a computer lock system including a computer main body 0700 and a receiving antenna device 0710, and the receiving antenna device 0710 includes an antenna signal receiving unit 0711 and an antenna signal. The computer main body 0700 is composed of an output unit 0712, and the computer main body 0700 includes an antenna signal acquisition unit 0701, a judgment unit 0702, an availability status information holding unit 0703, an enablement unit 0704, an unavailability unit 0705, and a control unit. It has 0706, and further has a screen saver unit 0707 and a competitive adjustment unit 0708.

<Explanation of Embodiment 4 Configuration>
<Embodiment 4 Screen Saver Unit>
The "screen saver unit" 0707 outputs the screen saver screen to the display when there is no input from the interface for a predetermined time. Examples of the interface include keyboard input and mouse input. If there is no such input for a predetermined time, the screen saver screen is output. Usually, it is possible to set from several minutes to several tens of minutes by user setting. If this screen saver is used for locking purposes so that the user cannot access the computer without permission, for example, when the user is away from the desk, it is likely that the screen saver is set to a few minutes. For example, if the OS of the computer is a Windows (registered trademark) personal computer (Windows 10, Windows 8.1, Windows 7, etc.), display the control panel screen and select Customize Desktop → Personal Settings to set the screen saver. .. If you check "Return to logon screen when restarting" on the screen saver screen, the screen saver will be interrupted (for example, it will be interrupted by interface input such as moving the mouse or key input on the keyboard). When I try to do so, the logon screen appears and I am prompted to enter the password.
If no screen saver is set, the screen saver screen will not be displayed, so there will be no problem with this computer lock system. If the above-mentioned "Return to logon screen when restarting" is checked, there is a risk of conflict with this computer lock system, so it is necessary to consider the conflict between the operation of the control unit 0706 and the operation of the screen saver unit 0707. ..

<Embodiment 4 Competitive Adjustment Unit>
When the operation of the control unit 0706 and the operation of the screen saver unit 0707 conflict with each other, the "competition adjustment unit" 0708 gives priority to the operation of the control unit 0706. The operation of the screen saver unit includes both a screen saver screen display operation and a logon screen display operation when work is resumed.

As shown in FIG. 8, the use of the interface when the operation of the control unit and the operation of the screen saver unit conflict with each other will be described. The interface usage in FIG. 8 is OK when (1) the screen saver does not start and (2) the screen saver starts but the password does not need to be entered.

When the operation of the screen saver unit is OK and the operation of the control unit is OK, the interface usage is OK. Even if the operation of the screen saver is NG (when the screen saver determines that the screen saver screen display operation or logon screen display operation should be performed), when the control unit operation is OK, the interface use is OK and control. The operation of the part is prioritized. Further, even if the operation of the screen saver unit is OK (when the screen saver unit determines that the screen saver screen display operation or the logon screen display operation should not be performed), if the operation of the control unit is NG, the operation of the control unit has priority. Then, the interface usage becomes NG. If the operation of both the screen saver unit and the control unit is NG, the interface usage is also NG.

As described above, this computer lock system will operate.
Since other configurations are the same as those of FIG. 2 of the first embodiment, the description thereof will be omitted.

<Embodiment 4 Action: Hardware configuration (computer body)>
As shown in FIG. 9, the configuration of the computer of the computer main body includes a CPU 901, a non-volatile memory 0902 such as an HDD and a ROM, a main memory 0903 such as a D-RAM, an interface 0904, a display interface 0905, and a keyboard interface 0906. It is composed of a network interface 0907. Programs such as a screen saver program and a competition adjustment program are stored in the non-volatile memory 0902. The data includes an antenna signal, an unlock ID, available status information, and the like. These programs and data are read into the holding area of the main memory 0903 and executed in the work area. Since the other programs are the same as the configuration of FIG. 4 of the first embodiment, the description thereof will be omitted.

<Example 4 Processing flow Receiving antenna device>
As shown in the right figure of FIG. 10, when the antenna signal receiving step 1001 and the antenna signal output step 1002 are executed, the antenna signal from the receiving antenna device 0710 is input to the externally contacted computer body 0700. Since the processing of the antenna signal receiving step 1001 and the antenna signal output step 1003 is the same as the antenna signal receiving step 0501 and the antenna signal output step 0502 of FIG. 5 of the first embodiment, detailed description thereof will be omitted.

<Example 4 Processing flow Computer body>
As shown in the left figure of FIG. 10, the operation of the computer of the computer body as described above is to execute the antenna signal acquisition step 1003, the determination step 1004, the enablement step 1005, the disabling step 1006, and the control step 1007. Therefore, it is determined whether or not the acquisition unit signal from the antenna signal acquisition unit 0701 includes the unlock ID as shown in FIG. 3 (step 1004), and the enablement step 1005 and the unavailability step 1006 are executed. Then, the available status or the unavailable status of the available status information holding unit 0703 is always held as the available status information. Since the processes from process steps 1003 to 1007 are the same as the processes from process steps 0503 to 0507 in FIG. 5 of the first embodiment, detailed description thereof will be omitted.

In the state as described above, the screen saver activation timing determination step for determining whether the screen saver activation timing is executed is executed (step 1008). As a result of the determination in the screen saver start timing determination step 1008, in the case of the screen saver activation timing, the operation with the control program and the operation of the screen saver program conflict with each other. Therefore, a conflict adjustment step that prioritizes the operation of the control unit is executed (step 1009). .. Here, the screen saver start timing is the timing when the screen saver determines that the screen saver should be started from the state where the screen saver is not started, and the screen saver is already started and the operation of the screen saver is continued. It shall also include the timing of deciding whether to do so. In addition to the operation of displaying the screen saver, the operation of displaying the logon screen shall be included in the activation of the screen saver.

In response to the result of the adjustment in the competition adjustment step, the screen saver activation determination step of whether to activate the screen saver is executed (step 1010). If the screen saver activation state is recognized in the conflict adjustment step, the screen saver step is executed (step 1011). The screen saver step displays the screen saver on the display or displays the logon screen on the display. If the screen saver does not start, leave it to the control of the control unit. After the screen saver is activated or after the control is entrusted to the control unit, the usage end determination step is executed (step 1012).

If it is not determined that the usage has ended in the usage end determination step, the process returns to the antenna signal acquisition step again. There are two ways to return, one is to return to the antenna signal acquisition step with the screen saver activated, and the other is to return to the antenna signal acquisition step without starting the screen saver. When the screen saver is activated, the control unit normally disables the display interface based on the unavailable status, which is the status in the usage status information, and as long as the control state continues. The conflict adjustment step of keeping the screen saver up or making the control state available to the normal display interface is repeated. If the determination unit determines that the unlock ID is included in the acquisition unit signal while the screen saver is ongoing, the enablement unit changes the available status information to the available status, and the competition adjustment unit accordingly. Does not make a decision to release the screen saver, but prioritizes the control of the control unit and adjusts the conflict with the display interface so that it can be used normally. Along with this, the screen saver activation judgment determines that the screen saver is not activated, that is, the screen saver is terminated, and the display becomes available in the normal usage state.

The above-mentioned process is repeated until the user ends the use of the computer (step 1012).

As described above, according to the fourth embodiment, in addition to the first to third embodiments, when the screen saver of the Windows (registered trademark) personal computer and the computer lock system conflict with each other, the control of the lock system is prioritized. User-friendly security can be maintained.

<Embodiment 5>
<Overview>
The fifth embodiment is a computer lock system based on any one of the first to fourth embodiments and having some features. In the fifth embodiment, when the display interface is normally unavailable (computer locked), the available status information can be used when the correct password is accepted even if the unlock ID is not included in the acquisition unit signal. The feature is that it is fixed to the status.

<Configuration 5>
As shown in FIG. 11, the computer lock system of the fifth embodiment is a computer lock system including a computer main body 1100 and a receiving antenna device 1110. The receiving antenna device 1110 includes an antenna signal receiving unit 1111 and an antenna signal.

It also has a password input receiving unit 1107, a password determining unit 1108, and an available status fixing unit 1109.

<Explanation of Embodiment 5 Configuration>
<Implementation 5 Password Input Reception Unit>
The "password input receiving unit" 1107 is a determination result that the determination result by the determination unit 1102 does not include a valid release ID, and the display interface of the computer main body 1100 is in a state where the display cannot be normally used. , Judge whether or not to accept password input. For example, when a password is input from a keyboard connected to the computer or a software keyboard displayed on the touch screen of the tablet PC, the process proceeds to the password determination unit 1108.

<Example 5 Password determination unit>
The "password determination unit" 1108 determines whether the password is a correct password. Here, for example, if the computer itself is a Windows (registered trademark) personal computer, the password is judged to be normal if it is the same as the login password set for the computer.

<Embodiment 5 Available status fixed part>
The "available status fixing unit" 1108 forcibly uses the available status information of the available status information holding unit 1103 when the determination result of the password determination unit 1108 is the determination result that the password is the correct password. Fixed to possible status.
That is, if the password is normal, the computer lock system fixes the available status information of the available status information holding unit 1103 from the unavailable status to the available status. The display interface of the computer becomes normally available. This configuration is because an emergency evacuation measure is required in the unlikely event that the source of the unlock ID breaks down or the source of the unlock ID is lost. Therefore, it is preferable that this password is kept secret by a person with high authority such as a system administrator of the company. Also, if you use this password to unlock and then intermittently determine whether or not to acquire the unlock ID, there will be a problem that the unlocked state can be maintained for only a few seconds, and the lock is effectively unlocked. It becomes impossible to operate a computer. Therefore, when the lock is unlocked by using the password, the normal processing such as the acquisition determination of the unlock ID is stopped and the status of the always available status information is fixed to the available status. Since other configurations are the same as those of FIG. 2 of the first embodiment, the description thereof will be omitted.

<Embodiment 5 Action: Hardware configuration (computer body)>
As shown in FIG. 12, the computer configuration of the computer body includes a CPU 1201, a non-volatile memory 1202 such as an HDD and a ROM, a main memory 1203 such as a D-RAM, an interface 1204, a display interface 1205, and a keyboard interface 1206. It is composed of a network interface 1207. The non-volatile memory 1202 stores programs such as a password input reception program, a password determination program, and a availability status fixing program. The data includes an antenna signal, an unlock ID, available status information, and the like. These programs and data are read into the holding area of the main memory 1203 and executed in the work area. Since the other programs are the same as the configuration of FIG. 4 of the first embodiment, the description thereof will be omitted.

<Example 5 Processing flow Receiving antenna device>
As shown in the right figure of FIG. 13, when the antenna signal receiving step 1301 and the antenna signal output step 1302 are executed, the antenna signal from the receiving antenna device 1110 is input to the externally contacted computer main body 1100. Since the processing of the antenna signal receiving step 1301 and the antenna signal output step 1302 is the same as the antenna signal receiving step 0501 and the antenna signal output step 0502 of FIG. 5 of the first embodiment, detailed description thereof will be omitted.

<Example 5 Processing flow Computer body>
As shown in the left figure of FIG. 13, the operation of the computer of the computer body as described above executes the antenna signal acquisition step 1303, the determination step 1304, the enablement step 1305, the disable step 1306, and the control step 1307. Therefore, it is determined whether or not the acquisition unit signal as shown in FIG. 3 from the antenna signal acquisition unit 1101 includes the unlock ID (step 1304), and the enablement step 1305 and the unavailability step 1306 are executed. Then, the available status or the unavailable status of the available status information holding unit 1103 is always held as the available status information. Since the processes of the process steps 1303 to 1307 are the same as the processes of the process steps 0503 to 0507 of FIG. 5 of the first embodiment, detailed description thereof will be omitted.

Under the lock control of the control step 1307 in the above-described state, the display interface of the computer main body executes a step of determining whether or not the display cannot be normally used (step 1308). If it is not in an unusable state (step 1308), the process returns to the process of the antenna signal acquisition step 1303.

If the display interface of the computer is in a state where the display cannot be used normally (unusable state) (step 1308), the password input acceptance step is executed to determine whether or not the password input is accepted by the password input acceptance program (step 1308). 1309). Next, the password determination program executes a password determination step for determining whether the password is a correct password (step 1310). Next, when the determination result in the password determination step 1310 is the determination result that the password is the correct password, the available status information of the available status information holding unit can be forcibly used by the available status information fixing program. Execute the available status fixing step of fixing to the status (step 1311). Next, the control is passed to the lock control process in the control program (step 1312). The control unit performs the process based on the available status, but the available status information is fixed at the available status, so that the computer is used. The display is controlled to be available in the normal state until the end of. Further, it is preferable that the status is fixed to the available status even when the power is turned off and then restarted. Next, it is determined whether or not the user has finished using the computer (step 1313), and if it is not finished, the process returns to control step 1312 and the above-described processing is repeated. When the user ends the use of the computer (step 1313), for example, when the power of the computer is turned off, the lock system is terminated.

As described above, according to the fifth embodiment, in addition to the first to fourth embodiments, for example, in a Windows (registered trademark) personal computer or the like, even when the computer is locked, if the password is correct, the password input is accepted. Even if the display interface of the computer itself is in an unavailable state, the display interface can be changed to a normal usable state, so that a legitimate user of the computer can continue the work.

The conversion unit 1405 and the conversion unit 1405 inactivate the function of the display interface of the computer main body 1400 so that the display cannot be made normally unavailable. That is, it means that the function of this computer lock system is stopped.

<Embodiment 6 Action: Hardware configuration (computer body)>
As shown in FIG. 15, the computer configuration of the computer body includes a CPU 1501, a non-volatile memory 1502 such as an HDD and a ROM, a main memory 1503 such as a D-RAM, an interface 1504, a display interface 1505, and a keyboard interface 1506. It is composed of a network interface 1507. A program such as an inactivation program is stored in the non-volatile memory 1502. The data includes an antenna signal, an unlock ID, available status information, and the like. These programs and data are read into the holding area of the main memory 1503 and executed in the work area. Since the other programs are the same as the configuration of FIG. 12 of the fifth embodiment, the description thereof will be omitted.

<Example 6 Processing flow Receiving antenna device>
As shown in the right figure of FIG. 16, when the antenna signal receiving step 1601 and the antenna signal output step 1602 are executed, the antenna signal from the receiving antenna device 1411 is input to the externally contacted computer main body 1400. Since the processing of the antenna signal receiving step 1401 and the antenna signal output step 1402 is the same as the antenna signal receiving step 0501 and the antenna signal output step 0502 of FIG. 5 of the first embodiment, detailed description thereof will be omitted.

<Example 6 Processing flow Computer body>
As shown in the left figure of FIG. 16, the operation of the computer of the computer body as described above executes the antenna signal acquisition step 1603, the determination step 1604, the enablement step 1605, the disable step 1606, and the control step 1607. Therefore, it is determined whether or not the acquisition unit signal as shown in FIG. 3 from the antenna signal acquisition unit 1401 includes the unlock ID (step 1604), and the enablement step 1605 and the unavailability step 1606 are executed. Then, the available status or the unavailable status is always held in the available status information holding unit 1403 as the available status information. Since the processes from process steps 1603 to 1607 are the same as the processes from process steps 0503 to 0507 in FIG. 5 of the first embodiment, detailed description thereof will be omitted.

Under the lock control of the control step 1607 in the above-mentioned state, the display interface of the computer main body executes a step of determining whether or not the display cannot be normally used (step 1608). If it is not in an unusable state (step 1608), the process returns to the process of the antenna signal acquisition step 1603.

If the display interface of the computer is in a state where the display cannot be used normally (unusable state) (step 1608), an input acceptance determination step is executed to determine whether or not to accept the password input by the password input acceptance program. (Step 1609).

When the password input is accepted in the password input acceptance determination step 1609, the password determination step for determining whether the password is the correct password is then executed by the password determination program (step 1610).

Execute the available status fixing step of fixing to the status (step 1611).

If the password input is not accepted in the password input acceptance determination step 1609, the process returns to the antenna signal acquisition step 1603.

Next, when the available status information is fixed to the available status by the available status fixing unit 1409 by the deactivation program, the antenna signal acquisition unit 1401 and the judgment unit 1402 of the computer main body 1400 are disabled. The unit 1405 and the display interface of the computer body 1400 inactivate the function so that the display cannot be normally unavailable (step 1612). That is, it means that the function of this computer lock system is stopped. Next, control is passed to the lock control process in the control program (step 1613). The control program controls based on the available status information, but since the available status information is fixed to the available status, the control is fixed to the available state. Next, it is determined whether or not the user has finished using the computer (step 1614), and if it is not finished, the process returns to the control step 1613 and the above-described processing is repeated.
When the user ends the use of the computer (step 1614), for example, when the power of the computer is turned off, the lock system is terminated. However, if the power is turned on again after the power is turned off and the computer is restarted, it may be inconvenient if the lock system is activated again.
