Information Security System on the Basis of the Distributed Storage with Splitting of Data

摘要

Background/Objectives: Current importance of the investigation has been stipulated by the urgent problem of safe data storage. The study aims to develop a new method of data protection different from encryption. Methods: The principal approach to the investigation of the problem is represented by the method of data splitting within the distributed storage system that has been developed by the authors of the study. This system makes it possible to store the data preventing any unauthorized access. Separate split data do not carry any meaningful information. Another aspect is that the configuration of splitting/restoration can be designed in such a way that the data could be restored based on just a part of the split data; i.e. the data loss resistance can be ensured. Findings: The commonly adopted paradigm of IT-resources holds a deep-rooted disadvantage represented by poor data protection from external intrusion. The study represents the results of the investigations of the principally new method of data storage employing the algorithms of splitting/reconstruction resistant against partial loss of storage areas. The method is founded on the concept of storing the distributed data not in special depositories but rather as a corporate cloud. The specific features of the system provide unique opportunities for security. First, the system administrator, the IT engineer and the relevant qualified technical personnel, who possess the full access to the system, cannot, nevertheless, access the data that are out of their terms of reference. Second, the responsibility for information security is handed over to the person competent in this specific area. In particular, the author/owner of the document commands the security parameters of his/her document at his/her own discretion without being concerned about physical safety of the information that is within the competence of the technical service. High integrity of the results of the investigation and, consequently, high degree of safety are confirmed by good adaptive, functional and dynamic properties revealed by the information safety system based on the distributed storage technology employing data splitting on its introduction to cloud. Applications/Improvements: The study is of practical value for all IT systems including cloud technologies. The developed algorithm enables the implementation of the internally consistent model of safe data storage and processing.
