THE METHOD OF ASSESSING THE VALUE OF INFORMATION

Abstract

Context. The task of assessing the value of the institution’s information as one of the objects of protection of the information security model is considered. Objective. The goal of the work is the creation of a method of assessing the value of information, which takes into account the time of the final aging of information. Method. The results of the analysis of methods for evaluating the value of information showed that modern approaches are conventionally divided into two directions. In the first direction, the value of information is calculated as the amount of information in bytes. In the second direction, the value of information is calculated in monetary terms. It is shown that modern approaches do not take into account the influence of time on the value of information. A method of assessing the value of information is proposed, which takes into account such characteristics as the term of final aging of information, the level of its access restriction, importance, and form of ownership. The value of information is presented as a quantitative measure that determines the degree of its usefulness for the owner. It is proposed to calculate the value of the initial value of information during its creation or acquisition by calculating the normalized weight of the coefficients according to the formula of the arithmetic mean. It was shown that the current value of information has a functional dependence on the time of existence of information and the time of its final aging. Results. The results of the experiment confirm that the value of information has a nonlinear functional dependence on the time of final aging of information. Conclusions. The conducted experiments confirmed the efficiency of the proposed method of evaluating the value of information and allow recommending it for use in practice to protect the institution’s information. Prospects for further research may include the creation of a methodology for assessing the value of an institution’s information, taking into account the aging of information and subsequent adjustment of measures to protect it.
