To protect your data (data integrity) in the automated
systems, we provide a solution of the problem, which
is to reduce redundancy control of information (hash
codes, electronic signatures). We impose restrictions
on the maximum number of violations of the integrity
of the records in the data block. It is known, that with
an increase in data protection the amount of control
information (coefficient of redundancy) also increases.
We introduce the concept of linear systems of hash
codes (LSHC). On the basis of the mathematical
apparatus of the theory of systems of vectors we have
developed an algorithm for constructing LSHC, which
allows (for a given level of data protection, i.e.
integrity) to reduce the redundancy of the control
information. Rules (principles) of building LSHC
comply with the rules of construction in coding theory
(Hamming codes). The article provides an algorithm
for data integrity in LSHC. The use of algorithms
ensures the necessary level of data protection and the
requirements specification of customers
