Abstract

In a terminal capable of utilizing a plurality of networks, a leakage of the information between the networks is prevented. The terminal, upon acquiring data from the networks, extracts a data attribute such as a hash value, size, a magic number, or the presence or absence of encryption and stores it in the terminal. Subsequently, when an application attempts to access another network to transmit some sort of data, the terminal extracts the characteristics of the data and compares them with the data attributes stored so far. If there is no matching among them, the terminal permits the transmission of the data. If there is any matching, the terminal permits or inhibits the transmission according to the content of the data control policy that the terminal holds. The data control policy describes the data attributes and a policy for judging whether to permit or inhibit the transmission/reception of the data matching the data attributes.
