FIELD: information technologies.
SUBSTANCE: system to monitor integrity of files, including a unit to generate a hashing key, a unit to generate a hash code of files, a unit to store reference hash codes of files, a unit to compare hash codes, besides, the outlet of the hashing key generation unit is connected to the first inlet of the unit for generation of files hash code, the first outlet of which is connected to the inlet of the unit for storage of reference hash codes of files, the second outlet - with the second inlet of the hash codes comparison unit, the first inlet of which is connected with the outlet of the unit for storage of reference hash codes of files, the outlet - with the outlet of integrity monitoring results, differing by the fact that additionally a unit to build a network of Petri files of initial texts and a unit to store a Petri network in the form of the Petri network file are added, besides, the inlet of the unit to build a network of Petri files of initial texts is connected to the inlet of controlled files reading, the outlet - with inlet of the unit to store a Petri network in the form of a Petri network file, the outlet of which is connected to the second inlet of the unit for generation of file hash codes.
EFFECT: monitoring of files integrity in initial software texts, which does not depend on their formatting.
