Annotation: If the data is not available to the outside world, it is useless. The data must be available so that the necessary processing and planning can be carried out. Regulating and monitoring user access to a database is one of the important tasks of the database security community. Database protection against inference attacks is a part of information security that tries to prevent the disclosure of sensitive information through available information (tables, individual records). It is necessary to have methods capable of maintaining a balance between the use of information and the protection of data. The purpose of this work is to compare different inference control methods in order to evaluate the methods results to minimize both the loss of information and the risk of information disclosure.
