Privacy-Preserving, Scalable Blockchain-Based Solution for Monitoring Industrial Infrastructure in the Near Real-Time

Abstract

This paper proposes an improved monitoring and measuring system dedicated to industrial infrastructure. Our model achieves security of data by incorporating cryptographical methods and near real-time access by the use of virtual tree structure over records. The currently available blockchain networks are not very well adapted to tasks related to the continuous monitoring of theparameters of industrial installations. In the database systems delivered by default (the so-called world state), only the resultant or the last value recorded by the IoT device is stored. Effective use of measurement values recorded in the past requires each time viewing the entire chain of recorded events for a given IoT device. The solution proposed in the article introduces the concept of dependent wallets, the purpose of which is the aggregation and indexation of changes in machine parameters, recorded in the original wallets. As a result, we can easily get data from a certain sensor or sensors in the specified date range, even if the chain of transactions is very long. Our contribution is a universal mechanism that improves the efficiency of the infrastructure monitoring process, which uses blockchains to record measurements from sensors. The proposed model has been experimentally tested on two types of blockchains: Stellar and Hyperledger Fabric.

Information Sharing in Land Registration Using Hyperledger Fabric Blockchain

“…On an operational level, frameworks suggest various supportive strategies, such as encouraging the use of shared information, adopting sharing practices at the managerial level, and fostering trusted relationships based on mutual needs and joint responsibilities [19]. Technical issues also exist, such as the need for secure, immutable systems [27] that control access and prevent data manipulation [22]. In addition, the heterogeneity of systems across different institutions complicates integration [21,22].…”

Protecting Private Information for Two Classes of Aggregated Database Queries

“…Applying the row and column operations, we can reduce M to a normalized form. Then the system (11), simplifies and reduces to the normalized form…”

“…Reject the query, keep the matrix unchanged. Let D be a database with the set of MVQ queries answered so far stored in matrix form (11) with the normalized form (16). Then the following conditions are equivalent.…”

“…A large and rapidly developing area of modern informatics deals with security and privacy of data (see, for example, [1][2][3][4][5][6]). In particular, the preservation of privacy is crucial for broad adoption of digital payments [7], healthcare applications [8], location-based services [9], telemedicine [10], monitoring industrial infrastructure [11] and the Internet of things [12,13].…”

Enabling a Secure IoT Environment Using a Blockchain-Based Local-Global Consensus Manager

“…Additionally, IoT nodes may be attacked in several different ways. Hence, developing a reliable reputation evaluation scheme is important in establishing a secure and trustworthy IoT ecosystem for specific applications [7][8][9].…”
