Description

  The present invention relates to a mobile communication terminal system, a mobile communication terminal used in the system, a function restriction method, and a function restriction control program. For example, the user uses a mobile phone with a camera and enters a photographing prohibited area. In particular, the present invention relates to a portable communication terminal system, a portable communication terminal used in the system, a function restriction method, and a function restriction control program.

  In recent years, cellular phones are provided with a photographing function in most models, and can capture images as electronic data regardless of whether they are still images or moving images. In addition, this type of mobile phone can also instantaneously send captured image data to another place by a data transfer function. These functions are very convenient in daily life, but on the other hand, they may be accepted as threats. For example, there are many things on the company premises that correspond to confidentiality, such as products under development, but customers and inbound / outbound customers invited to the premises during business talks (for example, shipping companies and sales companies) Such a camera-equipped mobile phone captures these images and leaks them to the outside.

  As a countermeasure, there is a mobile phone with a camera that informs the surroundings of shooting by generating a pseudo sound such as a mechanical sound at the time of shutter opening / closing at the time of shooting, but nobody notices if there is no person around. The above problems are not improved. Some camera-equipped mobile phones have a function for setting the shooting function to be invalid. This function is set by the user and is set by the administrator of the shooting-prohibited area. However, the above problems are not improved.

  In addition, in order to prevent leakage of images such as products that cannot be placed out of customer's reach, while the customer is on the corporate premises, the manager of the prohibited shooting area on the premises will The sticker approved by the company can be attached to the lens of the mobile phone with a camera, or the mobile phone with a camera can be stored. However, in the former case, when a customer uses a camera-equipped mobile phone for a purpose other than photographing and the seal is damaged by force majeure, it is difficult for the company to determine the cause of the damage. As for the adhesive strength of the seal, there is no effect if it is weak, and if it is too strong, damage and contamination to the lens and the casing around the lens after the seal is peeled off from the site become a problem. In the latter case, it is the most effective countermeasure method for the company side, but it is inconvenient because it is impossible to use functions other than calling and photographing from the customer side.

In addition to the above-described mobile phone, conventionally, this type of technology has been described in, for example, the following documents.
In the mobile communication terminal described in Patent Document 1 (in the same document, “mobile phone device with camera”), the entire surface of the camera unit is covered with a slidable lid. For this reason, it is possible to recognize that the shooting function is not used.

In the portable communication terminal described in Patent Document 2 (“shooting restriction system” in the same document), shooting restriction information is transmitted from the shooting restriction information transmitting device and received by the short-range wireless communication unit of the portable communication terminal. Each part of the mobile communication terminal is controlled by the photographing restriction information. For this reason, in a mobile communication terminal having a photographing function, for example, photographing restrictions such as prohibition of photographing and prohibition of use of a flash in a photographing restriction area such as a movie theater, a theater, and a bank are easily and reliably performed. The short-range wireless communication unit is configured based on a wireless communication specification of Bluetooth (Bluetooth).

That is, as shown in FIG. 5, the user of the mobile phone 1 holds the non-contact IC card system data transmission / reception surface 16 over the non-contact IC card system data transmission / reception surface 24 of the non-contact IC card system reading unit 23 (step S8). ). At this time, the control unit 14 of the mobile phone 1 determines whether or not there is a reaction from the non-contact IC card system reading unit 23 (step S9). When the reaction is confirmed in step S9, the process proceeds to step S10.
If no reaction is confirmed in step S9, the process proceeds to step S13. In step S10, the control unit 14 of the mobile phone 1 reads information such as identification information, shooting prohibition setting information (shooting prohibition encryption key), and current date / time of the mobile phone 1 from the memory 10, and a non-contact IC card system reading unit. 23.

  In step S11, the control unit 14 transmits a command (shooting prohibition encryption release key) for the non-contact IC card system reading unit 23 to release the shooting prohibited state for the information transmitted in step S10. Determine whether or not. If the photographing prohibition descrambling key has been received in step S11, the process proceeds to step S12. If the photographing prohibition descrambling key cannot be received in step S11, the process proceeds to step S13. In step S12, the control unit 14 turns on the switch 18 in order to decrypt the photographing prohibition descrambling key and set the mobile phone 1 to the photographing permitted state. In the state of step S <b> 12, the mobile phone 1 can perform shooting by the shooting unit 17 and can use functions other than the shooting function such as a call and communication as usual. The photographing prohibition encryption key and the photographing prohibition descrambling key are discarded without being stored in the memory 10.

  On the other hand, in step S13, the mobile phone 1 waits for a response from the non-contact IC card system reading unit 23, and returns to step S9 until the waiting time set by the control unit 14 is reached. If it has passed (timeout), it returns to the start (START) state (shooting prohibited state).
