INFORMATION DISTRIBUTION SYSTEM, INFORMATION DISTRIBUTION APPARATUS, AND INFORMATION DISTRIBUTION METHOD

摘要

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.

主权项

1. An information distribution system comprising:
an information distribution apparatus; a sound wave generator; and a terminal, wherein the sound wave generator comprises an output unit configured to output a sound wave including first identification information for identifying the sound wave generator, the terminal comprises: a sound collecting unit configured to collect the sound wave output from the sound wave generator; and a first communication unit configured to transmit an information distribution request that includes second identification information for identifying the terminal and the first identification information included in the sound wave to the information distribution apparatus, and the information distribution apparatus comprises: a second communication unit configured to receive the information distribution request from the terminal; a determining unit configured to, 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 equal to or less than a threshold, determine that the second identification information included in the first information distribution request is valid; and a distribution control unit configured to, when the first identification information is valid, distribute distribution information associated with the first identification information to the terminal which has transmitted the information distribution request.
