SYSTEM AND METHOD OF SIMILAR FILES DETERMINING Russian patent published in 2017 - IPC G06F21/56 

FIELD: information technology.

SUBSTANCE: method of similar files determining, in which the set of immutable and mutable files characteristics are defined; in this case the file characteristics is considered as a variable sign, if the characteristic takes different values for a plurality of similar files. File characteristics are considered as immutable, if a characteristic takes the same value for a plurality of similar files; a variety of charateristics is separated from at least one file; a plurality of separated file characteristics is divided into at least two subsets: the subset of variable characteristics and a subset of the immutable characteristics; the convolution of each of the abovementioned subsets of file characteristics is formed; the file convolution is formed as a convolution combination of each of the abovementioned subsets of file characteristics; the convolution of at least one file is compared with a set of pre-designed file convolutions; the file is recognized as similar to the files from the plurality of similar files having the same convolution, if by comparison the convolution of the noted file is the same as the file convolution from the noted plurality.

EFFECT: finding of similar files.
