When storing data sets, as well as when working with them, ensuring integrity and acknowledgment of authorship represent the most important tasks along with ensuring confidentiality and accessibility of information. Elements of the blockchain technology can be applied to solve the tasks in the case of distributed data storage, in which content information objects are stored each on its server, and databases of integrity labels and information on authorship on several servers belonging to different organizations.

It is proposed to place the databases with the relevant information on N servers to confirm the authorship and integrity of the files, while the stored data consists of transaction descriptions, each of which contains a file integrity label and the author's ID, the formation of such a transaction can be done by the user's command similarly to the formation of an electronic signature. The authorship of the user that forms each transaction is confirmed by the system of authentication of the information system, within the framework of which the described algorithm is implemented. Each new transaction description is sent to all N servers, transactions are combined into blocks. A block containing transactions not yet included in other blocks is generated by one of the servers, and a mechanism must be provided that excludes the entry of the same transaction into different blocks.

The described logic of work differs favorably from the enhanced electronic signature, as the organization of certification centers, the verification of the validity of certificates, the periodic replacement of cryptographic keys with overwriting the entire file array is excluded.
