Long-term preservation of legally significant electronic document

Abstract

The article discusses the problem of ensuring the long-term preservation of legally significant electronic documents (LSED). An  overview of the problem and existing options for solving it are provided in the article. The paper frames a formal problem of ensuring the long-term preservation of legally significant electronic documents as an optimal control problem under conditions of parametric disturbances. This study briefly outlines the problems that arise when organizing the long-term preservation of electronic documents. The author also proposes documents safety indicators through documents and mathematical models for assessmentof the overall document  safety. The study  has resulted in development of algorithms that allow, being implemented in the form of software and hardware, to control and organize security. Examples of the practical implementation of the proposed approaches within the framework of large information systems are provided alongside with their advantages.  Implementation of suggested approaches can potentially  make it possible to comprehensively solve the important scientific and technical problem of organizing the long-term preservation of legally significant electronic documents. At the end of the article, further prospects for research aimed at solving the problem of long-term preservation of big data and systems built using distributed ledger technologies are identified.
