Abstract. The context of the knowledge based society is presented. The new user requirements in the context of the new society are analyzed. Basic concepts regarding the citizen oriented applications are presented. Issues specific to the citizen oriented applications are presented. The development cycle of the citizen oriented applications is analyzed. The particular elements for developing citizen oriented applications are described. The quality concept for the citizen oriented applications is defined. Quality characteristics and the costs of quality are defined and analyzed. A system of indicators for the quantification of the quality of the citizen oriented applications is developed. Ways of increasing the quality of the applications are analyzed. Issues as improving the users’ training level, implementing new development techniques, advanced testing techniques and the requirement of audit are approached. The concept of optimization is defined. Optimum criteria are defined and analyzed. Ways of optimizing applications are described. Security requirements are enumerated and described. The particularities of the security requirements for the citizen oriented applications are analyzed. Measures for ensuring the security of the citizen oriented applications are described. A citizen oriented application for the analysis of the structured entities is developed. The application collects data regarding the behavior of the users. The collected data are used for verifying the hypotheses regarding the quality characteristics if the citizen oriented informatics applications.
