Description

  The present invention relates to an authentication technique. In particular, the present invention relates to an authentication technique that is useful for proving that a certain place exists at a certain time.

  For example, the evaluation of a salesman is so-called that the results are all, but the evaluation of the process leading to it is also important. In other words, it is natural that the evaluation differs between the case where the sales effort is not made but the sales effort is made and the case where the sales effort is not made.

  However, the reality is that the managers are not fully aware of whether they are making sales efforts or not. In other words, even if the salesman contacts us by telephone, it is unclear whether or not he / she actually contacted from that location. For example, even if a photographed image is transmitted by a camera-equipped mobile phone, it is not known when it was photographed. Also, it is difficult to know where the photo was taken. For example, in a building town, the scenery is similar, and it is difficult to distinguish where. In particular, if it is a landscape in a building, it is difficult to understand where.

  In addition, there is a strong desire to know what the current situation is in construction sites such as civil engineering and architecture. In such a case, an image taken with a mobile phone is transmitted. Even in this case, however, it is unclear exactly where and when the image was taken. For example, it may be possible to send an image taken in the past in an attempt to indicate that the construction is difficult because the construction has already been completed, but in order to charge a high cost. Alternatively, it may be possible to transmit a similar image of a construction site.

So far, there is no effective technique to prove the current situation.
However, as described above, there is a great demand for a technique for proving the current situation.

This will be described in more detail below.
FIG. 1 is a block diagram of an authentication system according to the present invention, and FIGS. 2 and 3 are flowcharts of an authentication method according to the present invention.

  In each figure, A is a mobile terminal device such as a mobile phone, B is a server installed in a certificate authority, and C is a terminal device called a personal computer installed in an office affiliated with the certificate authority. Of course, C may be a portable terminal device. The portable terminal device A and the server B are connected via a communication line such as a wireless line, and the server B and the terminal device C are connected via a communication line.

  1 is a camera (photographing means) built into the mobile phone A, 2 is a GPS (Global Positioning System: global positioning system): 3 is a communication means of the mobile phone A, 4 Is a timer built in the mobile phone A, and 5 is a CPU (control means) built in the mobile phone A. The CPU 5 of the mobile phone A receives the image information taken by the camera 1, the position information obtained by the GPS 2, the time information at the time of transmission obtained by the timer 4, and the identification information (phone number) of the mobile phone A, and the communication means 3. Via the server B.

  6 is an input means (for example, a keyboard) of the server B, 7 is an output means (for example, a printer or a liquid crystal screen) of the server B, 8 is a memory (storage means) of the server B, 9 is a communication means of the server B, Reference numeral 10 denotes a timer built in the server B, and 11 denotes a CPU (control means) built in the server B. The CPU 11 of the server B causes the communication means 9 to receive information (image information, position information, transmission time information, and identification information) transmitted from the mobile phone A, and obtains this received information and the timer 10 of the server B. The reception time information is associated with and stored in the memory 8. In addition, when the mobile phone identification information is transmitted from the terminal device C described later, the CPU 11 of the server B receives it, and from the memory 8 based on the received identification information of the mobile phone A, Image information, position information, transmission time information, and reception time information to be read, and the read information (image information, position information, transmission time information, reception time information, and identification information used for reading) as a terminal device It is configured to transmit to C.

  12 is an input means (for example, a keyboard) of the terminal device C, 13 is an output means (for example, a printer or a liquid crystal screen) of the terminal device C, 14 is a memory (storage means) of the terminal device C, and 15 is a terminal device C. The communication means 16 is a CPU (control means) of the terminal device C. Then, the CPU 16 of the terminal device C transmits the identification information (telephone number) of the mobile phone A input by the input unit 12 to the server B through the communication unit 15, and the server B Information read from the memory 8 and transmitted is received, stored in the memory 14, and output to the output means 13.

  Next, the operation of the authentication system configured as described above will be described with reference to FIGS.

  First, a target portion is photographed with the camera 1 of the mobile phone A (step 1). At the same time, position information of the shooting location at the time of shooting is obtained by GPS 2 (step 2). Thereafter, the image information obtained in step 1 and the position information obtained in step 2 are transmitted to the server B via the communication means 3 (step 3). At this time, identification information (telephone number) of the mobile phone A is also transmitted at the same time. Further, time information at the time of transmission by the timer 4 is also transmitted simultaneously. That is, in step 3, the image information obtained in step 1, the position information obtained in step 2, the mobile phone identification information, and the time information at the time of transmission by the timer 4 are transmitted.

  Then, the communication means 9 of the server B receives the information (image information, position information, identification information, transmission time information) transmitted from the mobile phone A (step 4). After reception, the CPU 11 stores the received information in the memory 8 (step 5). At the time of storage in the memory 8, the CPU 11 stores information on the reception time obtained by the timer 10 of the server B together with the memory 8. That is, the memory 8 stores image information, position information, reception time information, and transmission time information in association with the identification information of the mobile phone A.

  The holder of the mobile phone A repeats the photographing work as necessary. Then, the captured image information and position information are transmitted to the server B, and the information is stored in the memory 8 one after another. Normally this ends. That is, unless a special situation occurs, the server B only receives and stores predetermined information sent from the mobile phone A.

  However, when an enrolled person in an office affiliated with the certificate authority tries to examine the mode of the holder of the mobile phone A, the following steps are repeated.

  In other words, a person in the office (superior of the holder of the mobile phone A) inputs identification information (telephone number) of the mobile phone A using the input means 12 of the terminal device C. This input information is transmitted to the server B via the communication means 15 (step 11). When the server B receives the identification information of the mobile phone A transmitted from the terminal device C, the CPU 11 of the server B reads information related to the identification information from the memory 8 (step 12). That is, in step 12, a series of image information, position information, reception time information, and transmission time information stored in association with the identification information of the mobile phone A is read. Then, the server B transmits the series of read image information, position information, reception time information, transmission time information, and identification information to the terminal device C (step 13). In response to this, the CPU 16 of the terminal device C receives the transmitted information, stores it in the memory 14 and causes the output means 13 to output it (step 14).

  When configured as described above, the holder of the mobile phone A can check what time, where and what. That is, the position information obtained by the GPS function and the image information obtained by the camera can be confirmed even at a distant place. In particular, even at a later date, the position information obtained by the timer of the server B can be obtained by the GPS function. The obtained position information and the image information obtained by the camera can be confirmed even at a remote place. Therefore, as long as the holder of the mobile phone A transmits information to the server B, the work performance of the holder of the mobile phone A can be checked. Therefore, if the salesman operates the mobile phone A of the present invention, it is possible to evaluate how to perform work even if the salesman has not achieved results. Also, if you take a picture of the construction site and send it to Server B, you can get a photo of the site at a specific time at the shooting location specified by the GPS function. Can be checked accurately. That is, since the position information, the image information at the position specified by the position information, and the time information at the approximate photographing time (reception time) are stored in one set, the accuracy of the holder of the mobile phone A Accurate behavior check and image information at a specific time at a specific time can be obtained accurately without being deceived. Therefore, it is very useful as a business weapon.

  Basically necessary time information is reception time information. However, if the transmission time information is also stored together, there is no problem if there is substantially no difference between the transmission time and the reception time, but if there is a substantial difference between the transmission time and the reception time, the mobile phone The holder of A can recognize that there is a time lag. As a result, when the holder wakes up the memory, this time gap can be taken into account, making it easier to remember when and where.
