Content providing system, content providing method, content providing program, and computer-readable recording medium

A content providing system comprising:

• content requesting means for sending a content transmission request to a content transmitting system for producing a content package including a content and transmitting thus produced content package to a user;
• content package receiving means for receiving the content package transmitted by the content transmitting system in response to the transmission request sent by the content requesting means;
• content package storing means including a specific area for storing the content package received by the package receiving means;
• content package alteration control means for erasing or altering a detail of the content package stored in the specific area and inhibiting the user from erasing and altering the detail of the content package stored in the specific area according to an instruction signal transmitted from the content transmitting system;
• content package reading means for reading out the content package stored in the specific area;
• and
• content providing means for providing the user with the content included in the content package read out by the content package reading means.

A content providing method comprising the steps of:

• causing content package receiving means to receive a content package, produced by a content transmitting system for transmitting a content to a user, including the content and attribute information concerning an attribute of the content from the content transmitting system;
• causing content package extracting means to extract according to the attribute information a specific content package from content packages received by the content package receiving means and store thus extracted specific content package into a specific area of content package storing means;
• causing content package alteration control means to erase or alter a detail of the content package stored in the specific area and inhibit the user from erasing and altering the detail of the content package stored in the specific area according to an instruction signal transmitted from the content transmitting system;
• causing content package reading means to read out the content package stored in the specific area;
• and
• causing content providing means to provide the user with the content included in the content package read out by the content package reading means.
