Two approaches to assessing the level of confidentiality of data to be included in a future document

There are considered two approaches to establishing confidentiality of documents on the base of expert opinions regarding the influence of confidentiality factors on the level of secrecy of information to be included in a future document. The final estimates of confidentiality levels for the arbitrary set of alternatives were obtained by these approaches, which are based on the application of the method of weighted coefficients of evaluation characteristics and the fuzzy inference. Additionally, comparative analysis of these approaches was carried out.
