In a modern society where the electronic government is being formed, state institutions and various commercial structures are trying to study and assess the behavior, interests, role and reputation of citizens in society based on personal data arrays. However, when people die, the information collected about them loses its immediate significance for current operational purposes. As a rule, this information is deleted or archived in accordance with the established protocols for data storage and legislative requirements for the protection of personal data of deceased persons. In the context of preserving national and cultural heritage, restoring historical memory and in-depth study of society, the process of collecting, structuring, and processing information about deceased persons is of particular importance. The concept of creating a digital twin of a deceased person by linking and processing different data represents an innovative approach to effectively immortalizing them. This article defines the role of information technologies in the preservation of cemeteries, explains the essence of the digital cemetery concept, and presents the general structure of the digital cemetery system. It determines the importance and potential prospects of the digital cemetery system for society, and develops proposals for its effective operation (pp.25-38).
