Abstract: An information providing system includes: a terminal device that acquires biological information as information on a user and transmits the biological information; and an information processing device, wherein the information processing device receives the biological information from the terminal device, analyzes condition of the user based on the biological information, judges whether content should be provided to the terminal device or not based on a result of the analyzing, and provides the content to the terminal device when judging that the content should be provided to the terminal device.

Abstract: A mobile information terminal of an information providing system includes a beacon reception unit that receives a beacon transmitted from a beacon transmitter, a wireless communication unit that communicates with a content server-via a network, a storage unit that stores a database, an activity judgment unit-that generates information based on activity of a user from information based on the beacon received by the beacon reception unit and stores a first information table including information based on the beacon and information based on the activity in the database, a URL generation unit that generates a URL indicating an access destination in the content server from the first information table, and a control unit that acquires content from the access destination indicated by the URL via the wireless communication unit.

Abstract: A radio transmission device includes: an information acquisition unit to externally acquire information data; an encryptor to encrypt the information data using one of a plurality of encryption processes used for encryption to generate transmission data; a radio field intensity setter having a different setting for each of the plurality of encryption processes used for encryption, the radio field intensity setter setting a radio field intensity at which the transmission data is to be transmitted; and a transmitter to transmit the transmission data at the set radio field intensity.

Abstract: An information providing system capable of providing beneficial content to a mobile information terminal carried by a user moving between areas includes the mobile information terminal and an information providing server. When transmission data is received, the information providing server extracts content corresponding to provision item information and category information included in the transmission data from a plurality of pieces of content included in a facility information table and transmits the extracted content to the mobile information terminal.
