خلاصة:

Information available on the web can be divided in two main categories. The first category is those information distributed among different websites and serveis. The second category is the information gathered in central information databases (infobases) which contain a huge amount of information and are available and searchable through the website representing the infobase. Infobase owners sell information to the users on per request basis, or to larger groups, based on the number of needed resources. Authentication is donc in one of two ways, or both of them: username/password and lP-based. The first approach has so many practicial problems so, in this paper a new approach has been proposed based on central system as an access-point and gateway for users to receive and retrieve their information using Squash technology. Thc architecture and advantages of this novel method have been discussed and the way of implementation has been described.

Infobase owners sell information to the users on per request basis, or to larger groups, based on the number of needed resources. The first approach has so many practicial problems so, in this paper a new approach has been proposed based on central system as an access-point and gateway for users to receive and retrieve their information using Squash technology. Squash, Infobase, Authentication The groMh of the Internet and web technologies in recent years has affected many different aspects of ourlives. The main problems with these methods are [4]: 0 Users must authenticate on each infobase separately, in case of username/password authentication. TH E NEW APPROACH To overcome the problems mentioned, we have designed a central system as an access- point and gateway tot users ot’ the whole region to access to the intobases. 4 uly/December, 2fl05 Iranian Journal of I uforntgtion Science & Technology, Volume 3, Number 2 There are many w‹tys thc gruups and the users benefit from this Jesign, the mosl important ‹›t” which arc: C Users need to authenticate ‹once on the Squash systcm, from then. A solution that solves the problem efficiently is to implement an standalone authorization module as a firewall, that loads the whole permissions database in memory, for a million users and hundreds of infobases, it can be done in at most 100MB of memory. Because of using many powerful and publicly available components, the source code for the whole project is very small, resulting in July/December, 2005 Iranian Journal of Information Science & Technology, Volume 3, Number 2 vci y low implementation and maintenance costs.
