Data Security Storage and Verification Mechanism Based on Distributed Ledger Technology

Abstract Blockchain, as a secure distributed ledger technology, has received extensive attention from academia and industry for its decentralization, comparability and traceability. This paper proposes a method for verifying data security on blockchain, and a cryptographic uploading and retrieval scheme is combined with IOTA blockchain technology. In this way, an IoT data storage and sharing model is designed to combine blockchain with IPFS. In this paper, it is found that there is a certain delay in operating on Fabric and IOTA compared to the scenarios that do not use blockchain. But Fabric has better performance in upload and download performance than IOTA. In the proposed scheme in this paper, the uploading time is stabilized between 0.8 and 1.2, and the retrieval time is stabilized between 0.43s and 0.76s, which has superior data uploading and retrieval performance than Scheme 1. Furthermore, the time to generate a key for a 50MB file is only around 1800ms, and for a 50MB file split into 6KB blocks, the time to generate a secret key is only around 36s. In this paper, when the file size reaches 5MB, the computational overhead of encryption and decryption is about 1315ms and 1283ms, respectively, and the time overhead of data consistency validation is only about 1095ms when the data block is cut into 6KB for a file of 5MB, indicating that this paper’s scheme has a lower time overhead in the generation of the secret key, encryption and decryption, and the data consistency validation. In summary, the above experiments verify the security and applicability of this paper’s scheme in data storage and verification.

Toward a Definition of Blockchain: Analyzing Definitions to Propose a Definition

Definitions serve a range of purposes, including providing meaning to a term, describing the characteristics of an object being defined, eliminating any ambiguity about the meaning of a term, demonstrating the etymology of a word, and so on. However, scholars hold differing opinions on everything from the necessity of definitions to the very existence of definitions. This disagreement is evident in various definition theories, types, and methods. This article aims to provide a tentative definition of blockchain using the Aristotelian method of definition, after thoroughly examining existing definitions in the literature. Many publications were collected from multiple databases to achieve this, and non-peer-reviewed literature was excluded. Subsequently, definitions were extracted from the literature using a semi-automated method, creating a mini corpus of definitions, which was then analyzed. During the analysis, it was observed that authors employ eleven class terms and several distinguishing characteristics to define blockchain. However, ten of the class terms were deemed unsuitable based on the analysis, and the definition was ultimately made on the concept of Distributed Ledger Technology (DLT). Nevertheless, the proposed definition is presented as tentative due to the absence of a precise definition for DLT and the ongoing evolution of blockchain. In the field of information systems, defining concepts logically is a rare occurrence caused by professionals' unfamiliarity with communication and logic principles. This study aims to provide a tentative definition of blockchain that will enable interested parties to have a consistent understanding of the term and lay the groundwork for future definitions in this domain.

Trustworthy AI for infrastructure monitoring: a blockchain-based approach

In the field of Artificial Intelligence (AI), there is an increasing focus on enhancing trustworthiness especially in critical sectors such as in the management of civil infrastructure. This paper proposes the adoption of a framework based on Hybrid Distributed Ledger Technology (Hybrid-DLT) as a technological solution for improving trustworthiness. We detail three specific applications in the sector of critical infrastructure maintenance: Explainable AI (XAI) for risk classification, structural defects recognition, and real-time monitoring through IoT. The proposed approach employs tamper-resistant ledgers for tracking key processes such as dataset collection, model training, and inference generation, thereby ensuring non-repudiability for recorded actions and enabling auditability. We demonstrate how this strengthens the explainability mechanisms of AI models and enables the production of verifiable data lineage and certified inferences. Our framework can be applied to existing AI solutions, enhancing their trustworthiness.
