In response to a request of an image delivery from a mobile phone 4, a gateway server 2 sets a user ID corresponding to an intrinsic identifier of the mobile phone 4 in the request, and transmits it to an IP server 1. The IP server 1 receives the request from the gateway server 2, and checks right and wrong of the image delivery based on the user ID that is being set in the request, and if a result of the check indicates a user to whom the image delivery may be conducted, a requested image data is transmitted to the mobile phone 4. The mobile phone 4 receives the image data, and holds the received image data in a storage region to which access from a user is restricted. <IMAGE> |
