METHOD FOR DISTRIBUTED DATA STORAGE WITH PROVEN INTEGRITY Russian patent published in 2021 - IPC G06F11/08 G09C1/02 

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology for distributed information storage. The expected result is achieved by the fact that the set of DISS storage nodes is divided into many local subgroups, in which the “leading” storage nodes are determined (for example, depending on the priority of the task being solved or the importance of the stored data on the storage nodes), which interact between the subgroups. Physical loss of any data storage node of the local subgroup (degradation of the DISS), inability to connect to the network due to deliberate (imitating) actions of an attacker, will lead to partial loss or complete loss of information. At the same time, a set of information data distributed among data storage nodes with calculated redundant data combined into a single data block by applying a recursive doubling operation allows the “leading” storage nodes performing a complete recovery of lost data files even if one or more data storage nodes of local subgroups fail.

EFFECT: increased information resilience of the distributed information storage system (DISS) to the deliberate imitating effects of an attacker.
