Description

  The present invention relates to a misplacement occurrence remote notification method, a misplacement occurrence remote notification system, a misplacement occurrence remote notification server, and a misplacement occurrence remote notification program.

  In recent years, many cases have been reported where laptop computers and important documents are left on train net shelves, etc., and eventually lost without being collected, resulting in leakage of confidential information. Such a case is a big social problem from the viewpoint of personal information protection.

  A device intended to prevent misplacement of valuables, and by monitoring the short-range wireless communication between the master unit and the slave unit, it is possible for the owner of the valuables to know the occurrence of misplacement Is known (for example, see Patent Document 1). Actually, products based on the same principle as the method described in Patent Document 1 are commercially available. In addition, a system intended to reduce costs and improve convenience by using a mobile phone on the base side has been studied (see, for example, Patent Document 2).

  Also, an apparatus has been devised that notifies misplacement based on disconnection of short-range wireless communication or a continuous decrease in reception level (see, for example, Patent Document 3).

  According to Patent Document 4, when a mobile phone and a portable device monitor each other's presence state and cannot receive the presence state, the fact is transferred to a predetermined transfer destination via the management center. It is described.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a first embodiment of a misplacement occurrence remote notification system according to the present invention. The misplaced occurrence remote notification system shown in FIG. 1 includes a base unit 100 for short-range wireless communication, handset units 101, 102, and 103, a mobile phone 302, a monitoring server 401, a monitoring terminal 402, and fixed phones 501 and 502. With.

  The master unit 100 and the slave units 101 to 103 have a short-range wireless communication function, and transmit and receive data. In addition, the mobile phone 302 and the monitoring server 401 are communicably connected to the base station 301 via a communication network such as the mobile phone network 300 and the IP network 400. In addition, the monitoring server 401 and the monitoring terminal 402 are connected to be communicable. The fixed telephones 501 and 502 can make a call via the fixed telephone network 500. The mobile phone 302, the monitoring server 401, and the monitoring terminal 402 operate according to a program.

  Base unit 100 is an adapter attached to an external connection terminal of cellular phone 302 possessed by valuables owner 10. Base device 100 is connected to, for example, an input / output terminal of mobile phone 302. The control unit of the mobile phone 302 monitors the communication status between the parent device 100 and the child devices 101 to 103 via the input / output terminal. Further, the power of the parent device 100 is supplied from the mobile phone 302. During normal operation, parent device 100 periodically communicates with child devices 101-103 having the short-range wireless communication function of the same standard, and confirms that child devices 101-103 are within a communicable distance. That the slave units 101 to 103 are within a communicable distance means that the slave units 101 to 103 are present around the valuables owner 10. When the communication standard is Bluetooth (registered trademark), the parent device 100 can communicate with one to seven child devices. Further, the distance at which the parent device 100 and the child devices 101 to 103 can communicate is within 10 meters.

  The slave units 101 to 103 have a short-range wireless communication function, perform a wireless communication with the master unit 100, and have a function of notifying that there is a slave unit within the communication range. The subunit | mobile_units 101-103 are each an independent terminal, Comprising: It attaches to the valuables 11, 12, and 13, respectively. The subunit | mobile_unit 101-103 is provided with a built-in battery as a power supply. Although FIG. 1 shows three slave units, the number of slave units is not limited to three. For example, four or more slave units (however, within 7 in the case of Bluetooth) may be used.

  The mobile phone 302 monitors a communication status between the parent device 100 and the child devices 101 to 103 by executing a program (an application developed by Java, BREW, or the like). Java is a registered trademark. For example, when the communication is continuously disconnected for a set time (for example, 30 seconds) or the reception power is continuously lower than a specified value, the mobile phone 302 can output voice or vibration or display a screen. It has a function of notifying the valuables owner 10 of the possibility that the valuables attached with the slave units have been misplaced. In this embodiment, the case where the parent device is connected to a mobile phone will be described, but it may be connected to a mobile terminal such as a PHS or PDA.

  FIG. 2 is an explanatory diagram illustrating an example of a warning screen for notifying the possibility that the valuables have been left behind. For example, a storage unit (not shown) such as a memory included in the mobile phone 302 stores the name of a valuable item to which the slave unit is attached in correspondence with the slave unit monitoring the communication status. The mobile phone 302 performs notification including, for example, the slave unit whose communication has been disconnected and the name of the corresponding valuable item. FIG. 2 illustrates a warning screen when communication with the child device 103 (child device No. 3) attached to the valuable item “important document” is disconnected.

  In addition, the mobile phone 302 may have a function of acquiring location information of the mobile phone 302 itself. For example, the mobile phone 302 receives a GPS signal from the GPS satellite 600 and obtains position information (latitude and longitude) based on the received GPS signal. In addition, for example, the mobile phone 302 obtains location information based on a signal received from the base station 301 using a location information service provided by a communication carrier. In this case, the mobile phone 302 displays a map of the place where the misplacement occurred on the screen of the mobile phone 302. FIG. 3 is an explanatory diagram illustrating an example of a map screen for notifying a misplaced occurrence point. The screen of the map of the place where the misplacement occurred is displayed, for example, by selecting a link provided on the warning screen illustrated in FIG.

  If the mobile phone 302 recovers communication or the received power does not become higher than the specified value within a predetermined time (for example, 60 seconds) after notification of the possibility that the valuables have been misplaced, the mobile phone 302 A data communication call to the monitoring server 401 is established via the network 300 and the IP network 400. Then, the mobile phone 302 provides the monitoring server 401 with, for example, the name and affiliation of the valuables owner 10, the phone number of the mobile phone 302, the number of the target handset, and the name of the valuables corresponding to the handset number. Etc. Further, when the mobile phone 302 has the function of acquiring the above-described position information, the mobile phone 302 also notifies the monitoring server 401 of the position information (for example, latitude / longitude, area name) at that time.

  The monitoring server 401 stores the data transmitted by the mobile phone 302 and displays it on the monitoring terminal 402 to notify the monitoring person 20. Therefore, the supervisor 20 recognizes the possibility that the valuables have been misplaced, and can take countermeasures such as contacting the valuables owner 10.

  In addition, the monitoring server 401 guides necessary contact information in a preset contact system table (for example, stored in a database in advance) in case the contact with the valuables owner 10 cannot be made. And a function for assisting the monitor 20 to take appropriate measures. When the mobile phone 302 has the function of acquiring the above-described position information and the position information of the location where the misplacement has occurred is obtained, the monitoring server 401 may have other relationships that may be able to rush to the location where the misplacement occurred in the shortest time. The person's contact information (for example, a landline telephone, a mobile phone number or an arbitrary e-mail address) is presented to the monitor 20. Here, the monitoring server 401 stores the positional information in association with the contact information of the parties concerned, and extracts the contact closest to the misplaced location based on the location information of the misplaced location and the location information of each contact. And presented to the supervisor 20.

  In addition, when another party has a mobile phone having a function of acquiring position information, the position information is periodically transmitted to the monitoring server 401 in advance, or when the misplacement occurs, the monitoring server 401 In response to the request, the mobile phone is caused to send back position information (center push function), thereby identifying the party closest to the location where the misplacement occurred, and presenting the mobile phone owned by the party as the highest priority contact.

  In the case where the monitoring person 20 who performs monitoring is absent or when it is difficult to make the monitoring person 20 resident, the monitoring server 401 uses the data transmitted from the mobile phone 302 for other optimal relationships by e-mail or the like. Forward to the person requesting action.

  Next, the operation of the first embodiment will be described with reference to the drawings. FIG. 4 is a flowchart showing the operation of the misplaced occurrence remote notification system in the first embodiment.

  In the following description, a case where the base unit 100 is attached to the mobile phone 302 and the handset units 101 to 103 are attached to the valuable items 11 to 13 is taken as an example. Further, a case where the valuables owner 10 wearing the mobile phone 302 moves with the valuables 11 to 13 as an example.

  The cellular phone 302 operates in accordance with the program, and causes the parent device 100 to confirm the responses of the child devices 101 to 103 periodically (for example, once every 10 seconds) by short-range wireless communication (step S1). When the mobile phone 302 confirms the responses of the slave units 101 to 103 within a certain time (for example, 5 seconds) (step S2), the mobile phone 302 determines that valuables are present around the valuables owner 10, and performs a monitoring operation. Is continued (step S3).

  After that, for example, the case where the valuables owner 10 forgets to leave the bag containing the valuables 13, leaves in the form of the mobile phone 302 and leaves the valuables 13 will be described as an example. When the parent device 100 and the child device 103 are separated from each other by a short distance wireless communication or more, the parent device 100 does not receive a response from the child device 103. When the base unit 100 requests the base unit 103 for a predetermined number of responses and communication between the base unit 100 and the base unit 103 does not recover after a predetermined time (for example, 30 seconds), the mobile phone 302 According to the program, it is determined that misplacement has occurred (step S4).

  When the cellular phone 302 detects the occurrence of misplacement, the cellular phone 302 notifies the valuables owner 10 of the possibility that the valuables 13 have been misplaced (step S5). For example, the mobile phone 302 performs a warning notification by performing output of sound, vibration, screen display (see FIG. 2), or a combination thereof in the mobile phone 302.

  Further, when the mobile phone 302 has a function of acquiring location information obtained using GPS or location information service, the mobile phone 302 receives and stores the current location information, and displays a map indicating the location where the misplacement occurred (step S6). In addition, the display of the map which shows the misplacement occurrence point is made possible by switching the screen display shown in FIG. 2 to the screen display shown in FIG. 3 by operating the mobile phone 302, for example.

  Here, when the valuables owner 10 notices misplacement and returns to a position where the parent device 100 and the child device 103 can communicate with each other, or the valuables owner 10 performs a release operation according to a predetermined procedure. In such a case, the cellular phone 302 cancels the notification by the voice, vibration output, screen display, or the like performed in step S5, discards the stored position information, and shifts to a normal monitoring state.

  On the other hand, if the above measures are not taken even after a lapse of a certain time (for example, 60 seconds) from the start of the warning notification, the mobile phone 302 passes the mobile phone network 300 and the IP network 400 to the head office 1. A data communication call to the installed monitoring server 401 is established. Then, the mobile phone 302 provides the monitoring server 401 with, for example, the name and affiliation of the valuables owner 10, the phone number of the mobile phone 302, the number of the target handset, and the name of the valuables corresponding to the handset number. Etc. In addition, when the mobile phone 302 receives the location information in step S6, the mobile phone 302 notifies the monitoring server 401 of the received location information together (step S7).

  The monitoring server 401 receives the data communication call from the mobile phone 302, receives and stores the information transmitted by the mobile phone 302 (step S8). Thereafter, the monitoring server 401 performs a data communication call release process, and ends the communication with the mobile phone 302 (step S9). Based on the end of the communication with the monitoring server 401, the mobile phone 302 displays a screen notifying that the misplacement remote notification has been completed, stops outputting voice and vibration, and completes the misplacement warning process ( Step S10).

  When the monitoring server 401 ends the communication with the mobile phone 302 in step S9, the monitoring server 402 transmits information indicating the occurrence of misplacement and related information transmitted by the mobile phone 302 as a misplacement occurrence notification (step S9). S11). The monitoring terminal 402 receives the information transmitted by the monitoring server 401, and outputs an alarm sound and a screen display for notifying the monitoring person 20 of the occurrence of misplacement and the contents thereof (step S12).

  In addition, the monitoring server 401 extracts appropriate contacts based on a predetermined contact list or the position information received in step S6, displays the contacts on the screen with priorities assigned (step S13). . When the monitoring server 401 receives the location information of the misplaced location from the mobile phone 302, the monitoring server 401 determines the location of the misplaced location based on the received location information of the misplaced location and the location information of each contact stored in advance. It is desirable to extract close contacts.

  For example, when the fixed telephone 502 of the related person 30 who is enrolled in the branch office 2 is presented as the optimal contact information, the supervisor 20 contacts the fixed telephone 502 from the fixed telephone 501 at hand through the fixed telephone network 500. The person concerned can be requested to deal with the misplacement (step S14). The person concerned 30 can make an effort to find and collect the misplaced valuables 13 by making a call on the fixed telephone 502, confirming the contents of the misplacement and urgently proceeding to the place where the misplacement occurred. (Step S15).

  As described above, in the present embodiment, even if the valuables owner cannot cope with misplacement, the remote response by an optimal third party other than the valuables owner is possible, thereby protecting the valuables. It is effective from the viewpoint of preventing information leakage.

  Also, in this embodiment, since the master unit is attached to the mobile phone, for those who have a habit of putting the mobile phone in a pocket of clothes, etc., put it in a bag etc. and leave it in transit However, since the owner of the valuables has the parent machine at hand, there is an effect that there is a high possibility of noticing misplacement.
