Confidentiality Simulation in a Simplified Database Model

In an e-commerce environment, databases are accesses constantly. This paper looks into the confidentiality issues involved in a simplified database access. In a simplified secured database access model, there are two groups involved: privileged group and public group which they can access data with any distribution. In order to secure the confidentiality policy of the database, this paper shows how to simulate an Erlang distribution which is used in a proposed semi-Markov chains.
