Free Information Usage System on the Network Introducing DACS Scheme

As a communication mean, personal portal, which is an entrance where each user can acquire his/her interested information on the network, is often used. We have problems to realize the personal portal described as follows. First, the program to realize the personal portal, which is located on a specific Web server, becomes large-scaled and complicated. Moreover, because Web pages as personal portal depend on that program, those pages can´t always be useful for each user equally. To solve these problem, we develop two kinds of new Web service which are realized on the network introducing DACS Scheme, which is the network management scheme by communication control of client computers. By use of these Web Services, regardless of information starage form, each user can create the customized personal portal to use information on the network easily and freely for oneself. That is, a free information usage system is realized.
