Blockchain Tree as Solution for Distributed Storage of Personal ID Data and Document Access Control.

Area of Science:

• Computer Science
• Information Security
• Cryptography

Background:

• Current methods for storing personal data on ID-cards lack robust security and efficient access control.
• Decentralized ledger technologies offer potential solutions for data integrity and security.

Purpose of the Study:

• To introduce a new Blockchain formation method for reliable personal data storage on ID-cards.
• To propose a novel Blockchain structure, "Blockchain Tree", for enhanced security and access control.
• To develop a multilevel protected system using an integrated Subchains approach.

Main Methods:

• Development of a new Blockchain structure named "Blockchain Tree".
• Design of a Subchains system for integrating lower-level Blockchains into higher-level ones.
• Modeling of an information system for ID-card data management.

Main Results:

• The proposed "Blockchain Tree" structure enables secure storage of ID-card information.
• Enhanced security and access control mechanisms are integrated into the Blockchain system.
• The Subchains system facilitates the creation of a multilevel protected data storage architecture.

Conclusions:

• The novel Blockchain formation method provides a reliable and secure solution for personal ID-card data.
• The "Blockchain Tree" and Subchains systems significantly improve data security and access management.
• This approach establishes a foundation for highly protected, multilevel data storage systems.
