摘要:
An information distribution system includes a sound wave transmitter, a mobile terminal, and an information distribution device. The sound wave transmitter transmits identification information to identify the sound wave transmitter. The mobile terminal receives the identification information and transmits the identification information to the information distribution device. The information distribution device is configured to transmit distribution information related to the identification information received from the mobile terminal to the mobile terminal. The information distribution device counts a number of the mobile terminal that transmits each identification information every predetermined period and identification information and transmits the distribution information to the mobile terminal that transmits the identification information in which the number of the mobile terminal reaches a predetermined number.

An information distribution system includes an information distribution apparatus, a sound wave generator that outputs a sound wave including first identification information, and a terminal that transmits an information distribution request. The information distribution apparatus includes a determining unit and a distribution control unit. When a distance between a location of the sound wave generator identified from the first identification information included in a first information distribution request received at a first time and a location of the sound wave generator identified from the first identification information included in a second information distribution request received at a second time prior to the first time is a threshold or less, the determining unit determines that the second identification information included in the first information distribution request is valid. When the first identification information is valid, the distribution control unit distributes distribution information associated with the first identification information to the terminal.

The terminal apparatus includes a memory configured to store arrangement information indicating arrangement of the one or more objects in the predetermined area and description information associated with the one or more objects; and a processor coupled to the memory and configured to obtain area identification information for identifying the predetermined area when the terminal apparatus is located in the predetermined area, identify a positional relationship between the terminal apparatus and the one or more objects based on the arrangement information when the area identification information is obtained, and cause the terminal apparatus to describe an object of the one or more objects, in accordance with the identified positional relationship between the terminal apparatus and the one or more objects.
摘要:
An identification information transmitter encrypts identification information for identifying a person or an object using an encryption key, transmits the encrypted identification information, and, after receiving another encryption key, switches the encryption key from the encryption key to the other encryption key. A server receives the encrypted identification information from the identification information transmitter, determines whether the encryption key is to be switched, and, if the encryption key is to be switched, generates the other encryption key. Another server authenticates the identification information that an identification information receiver receives from the identification information transmitter, and, if authentication is successful, acquires the other encryption key from the server, and transmits the other encryption key to the identification information receiver. The identification information receiver, when receiving the other encryption key from the second server, transmits the other encryption key to the identification information transmitter.
