Abstract: An information processing system includes one or more server devices functioning as a first platform that provides a first game to a first user having a first account, and one or more terminal devices. The one or more terminal devices transmit, to the first platform, an authenticated ID of a second user having a second account of a second platform that provides a second game. The authenticated ID is authenticated by using information concerning the second account. The first platform generates a specific ID upon receiving the authenticated ID, stores the authenticated ID and the specific ID in association with each other, and provides the first game to the second user using the specific ID associated with the authenticated ID.

Abstract: The present invention is aimed to provide a system for providing, to a terminal device of an investor, data indicating delay of distribution of financial data, which data is used for the investor to make decisions on investment transactions in a simple and reliable way. To achieve the above aim, after entity 20 carries out specific processing of financial data received from financial data broadcasting device 10 to generate new financial data derived from the received financial data, entity 20 adds time data and an entity identifier for identifying entity 20 to the derived financial data and transmits the data to another entity 20 located at a downstream position or to financial data searching device 30.
