The article is devoted to the substantiation of one of the directions of scientific research of the authors – the problems of database security. These studies are aimed at developing and testing new solutions, in particular, providing error correction and partial losses using multidimensional parity algorithms when splitting files. A review of the state of methods and algorithms for the functioning of distributed databases reveals one of the main aspects of the DD security problem - the reliability of information storage. With the increase in physical storage capacity to secure backup storage and the consequent increase in cost and power consumption, a security technology that uses multivariate parity algorithms that are robust to partial loss of storage locations, allowing multiple disks to fail even simultaneously, is an alternative security option.
