Method of calculating of the information in social networks protection depending on the number of communities

A mathematical model (linear system of differential equations) was developed and a research the personal data protection against number communities intensity transfer in social networks conducted. The linear information sense this term is considered. When described by models, object should be linear, at least approximately. This approach makes it quite simple to consider models. If such thing not noticed, necessary examine security for linearity. Such dependecies has been studied: dependence amount flow network on components protection, data, speed flow; size (as well as data); threats communities, also calculated: – coefficient representing impact measures; leakage rate; influence its leakage; security; connections networks; vertices parameter can used configure partitioning algorithm. solution obtained - harmonic oscillator equation, which breaks down into three cases: pre-resonance zone, resonance zone post-resonance zone. So, parameters investigated. study useful important from point view network, since significant influence, up 100%, per indicator. As result research, established that systems are non-linear.
