Abstract: A bandwidth control server, a bandwidth control program recorded on a computer readable record medium, and a monitoring system that control the sending of image data obtained by cameras in accordance with priority corresponding to a situation. A setting information storage section stores setting information regarding a camera installed at each point. When disaster information is acquired, a disaster detection section extracts a disaster type and a disaster area from the disaster information. A priority determination section searches the setting information on the basis of the disaster type and the disaster area and extracts setting information corresponding to the disaster type. Then the priority determination section determines priority for sending image data obtained by cameras installed in the disaster area on the basis of the extracted setting information.

Abstract: A data retrieval system is provided in which it is obligatory for a user to sign up as a member by registering with the system to register a message on a server. When registering the message, the member specifies at least one e-mail address of a person (permitted user) who is permitted to view the message registered by him/her. A seeker need not register to retrieve a message from the server. However, the seeker should have been specified as a permitted user by at least one member. In other words, as the server returns as a search result only the messages of the member who has specified the e-mail address of the seeker as the permitted user, the seeker who has not been specified as a permitted user by any of the members will be unable to view any message.
