Description

  The present invention relates to a terminal control system, a terminal control method, a portable terminal, and a terminal control server.

  After the enforcement of the Personal Information Protection Law (2005), personal information leakage accidents due to loss of mobile terminals, etc. have become a social problem, and countermeasures against information security by companies have become an important theme. For example, personal information and other company secret information are taken out using a mobile phone, and information leakage occurs due to loss or theft of the mobile phone. In addition, there is an act that a company employee intentionally leaks information, and countermeasures based on the premise that even an employee cannot be trusted are required. When information is leaked by employees, the information is copied using the camera function, external memory function, infrared communication, Bluetooth (registered trademark), IC card peripheral communication function, etc. There is a case of leaking.

Since such a mobile phone does not have a function that leads to information leakage from the beginning, problems such as information leakage by employees cannot occur in the first place, which is useful for companies that place importance on information security.

  However, mobile phone usage is generally done by using one mobile phone for both private and business use, and mobile phone companies provide a public / private billing service that separates work and private bills. Is also provided. In such a usage mode, mobile phones that do not have camera functions, external memory functions, and peripheral device communication functions are very difficult to use for private use, and can meet the demands of mobile phone users. The opposite problem of disappearing has also arisen.

  As a countermeasure against the above problems, there is a method of switching between available / unavailable states for the function of the mobile phone according to the situation of the user who uses the mobile phone. For example, when you are in the office, you can not use the camera function, external memory function, and communication function with peripheral devices as information security measures, but you can use these functions when you are outside the company. Conceivable.

For example, Patent Document 1 realizes a remote control system for a mobile device that can restrict the function of the mobile phone and prevent the use of the mobile device in a specific area. Further, Patent Document 2 proposes a mobile phone mode switching system and method for automatically setting a mobile phone of a user driving a vehicle to a drive mode.
