## 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).

## Claims

### Claim 1

A content delivery system comprising a transmitting terminal, a plurality of receiving terminals, and a delivery server,
wherein the delivery server comprises a database which registers a user ID of a sender who transmits a picture content and a user ID of each of a plurality of receivers who receives the picture content in association with each other, and a content storage which stores the picture content transmitted from the sender,
wherein, in a case that the transmitting terminal transmits a new picture content to the delivery server, each of the plurality of receiving terminals receives a first notice indicating that the new picture content is stored in the content storage,
wherein each of the plurality of receiving terminals displays a list of the picture contents which are transmitted from the transmitting terminal and stored in the content storage, information about a sender who transmitted the listed picture contents, and a comment inputted by the transmitted terminal, and
wherein, in case that one of the plurality of receiving terminals sends a request of rejecting the receiving of the picture contents to the delivery server, the list of the picture contents are not displayed on the receiving terminal which sent the request.

### Claim 2 (depends on 1)

The content delivery system according to claim 1, wherein each of the plurality of receiving terminals further displays a group of picture contents.

### Claim 3

A method for delivering picture contents among a transmitting terminal, a plurality of receiving terminals and a delivery server including a database which registers a user ID of a sender who transmits a picture content and a user ID of each of a plurality of receivers who receives the picture content in association with each other, and a content storage which stores the picture content transmitted from the sender,
the method comprising the steps of:
transmitting from a transmitting terminal a new picture content to the delivery server, wherein each of the plurality of receiving terminals receives a first notice indicating that the new picture content is stored in the content storage, and
displaying, by each of the plurality of receiving terminals, a list of the picture contents which are transmitted from the transmitting terminal and stored in the content storage, information about a sender who transmitted the listed picture contents, and a comment inputted by the transmitted terminal,
wherein, in a case of sending a request of rejecting the receiving of the picture contents to the delivery server by one of the plurality of receiving terminals, the list of the picture contents are not displayed on the receiving terminal which sent the request.

### Claim 4 (depends on 3)

The method for delivering picture contents according to claim 3, further comprising the step of displaying, by each of the plurality of receiving terminals, a group of picture contents.
