title: Confidentiality modelling and simulation and validation in a simplified database access.
abstract: In a simplified secured database access model, privileged group and public group can access data with any distribution. In order to secure the database, the confidentiality policy must be applied. Often, the management of the database privacy is neglected because data integrity has a higher priority in an environment dealing with insensitive data. This paper looked into the data confidentiality management and suggested use semi-Markov chains to model the security policy. A simulation experiment was used to validate the model.
