  • Publication number: 20240089344
    Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).
