Security in Cyberspace: A knowledge-base approach

In Cyberspace, realized by the Electronic Super-highway and multimedia techniques, persons will be represented by 'things' (so called 'alter-egos') grown out of the traditional social security numbers. In this paper we will study how the object-oriented methodology can help in designing these inhabitants. By using an interesting example, namely home banking, we will study the problem of security and privacy, in general: access protection, in this world. New in this paper is the combination of Cyberspace, Alter-ego objects representing its inhabitants and protection problems. In particular, we will demonstrate the need for knowledge based capabilities for handling the complex security features which are required in the Cyberspace world.
