Description

  The present invention relates to an information sharing system using a mobile terminal device in which a plurality of mobile terminal devices can easily and safely share information via a server device.

It is desired to realize a simple and safe information sharing system using a mobile terminal device that can acquire necessary information on demand using a mobile terminal device that can be used anytime and anywhere. As an example, a system has been proposed in which information related to a consumer's property is stored in a consumer's home server device and referred to when purchasing a product (see Patent Document 1). As a general online storage service system, a system that can share information among group members via a server device disposed on a network is also known.

  However, the following problems to be solved remain in the above system. For example, assume that a system is configured in which information related to a consumer's property is stored in the consumer's home server device and is referred to when the product is purchased. In such a case, a dedicated home server device (server device managed by the consumer) that functions for such a specific application is required. In addition, a consumer who manages the home server device must store all his / her property information in the home server device in advance. Also, since online storage service systems use group members on the network as information sharing partners, it is difficult to determine whether or not the other party is really a reliable partner. There was a possibility of being involved in threats such as leakage and unauthorized use.

  The present invention is an information sharing system using a mobile terminal device in which each of a plurality of mobile terminal devices connected to a network acquires user information related to a user of another mobile terminal device from a server device connected to the network.
