An object of the present invention is to carry out publication control for a portion of contents according to its valid period. This invention includes: reading out publication data including first data whose publication should be controlled, publication control condition data relating to a valid period of the first data, and second data whose publication does not have to be controlled from a publication data storage storing the publication data to judge whether or not a condition defined in the publication control condition data is satisfied; and upon detecting that the condition defined in the publication control condition data is satisfied, generating current publication data including the first data corresponding to the publication control condition data whose condition is judged to be satisfied and the second data and outputting the generated current publication data. In this way, when the publication of the first data is controlled based on the publication control condition data concerning the valid period, it becomes possible to control not to open information whose validity has been lost such as the contact telephone number to inquire the event, to the public, for example, after the event ended or the like.
