Abstract
This paper introduces a new method of Blockchain formation for reliable storage of personal data of ID-card holders. In particular, the model of the information system is presented, the new structure of smart ID-cards and information on these cards are proposed. The new structure of Blockchain, “Blockchain Tree”, allows not only to store information from ID-cards but also to increase the level of security and access control to this information. The proposed Subchains system allows us to integrate Blockchain of the lower level to Blockchain of the higher level, allowing us to create a multilevel protected system.
Highlights
The use of information resources and government services in the modern world implies unambiguous user identification
We further consider the methodology we propose for constructing Blockchain for the network, all nodes of which are verified servers of “Migration Police” that store personal information about citizens and existing ID-cards
We introduce a novel methodology based on Blockchain for building storage, access control, and document verification mechanisms for migration control area
Summary
The use of information resources and government services in the modern world implies unambiguous user identification. While it is well known, this algorithm uses too many resources to generate blocks; it is too slow and in many cases not necessary for building Blockchain This is why we believe that POW and other resource-intensive algorithms should not be used when it comes to the public and public services; for example, when all nodes of a network are well known and are state organizations. This structure of chain may be used for implementation of Blockchain in systems for checking smart tickets in transport, driver licenses, education degree documents, etc.
