Blockchain‐based secure information sharing for supply chain management: Optimization assisted data sanitization process

Abstract

Currently, the furious competitiveness in global markets and speedy improvements in information technology lead to shorter product life cycles, lesser transportation capabilities, and increased demands as well. In most business scenarios, the supply chain network is becoming one of the most vital focusing areas. In the supply chain network, blockchain technology is a promising solution for secure information sharing. However, it is a bit critical in maintaining security at each level of the blockchain and hence the public-private-key cryptography is more commonly preferred. This study intends to construct a new privacy preservation model in the field of supply chain networks based on blockchain technology by undergoing three major phases, namely, (a) data sanitization, (b) key generation, and (c) restoration. Further, the sensitive fields in the original data are selected during the data sanitization phase, and in the key generation phase; the optimal key is generated to hide the selected sensitive fields. The hidden data with the secured key is transferred from the source (manufacturer) to destination (vendor) in the supply chain network via the blockchain. The restoration process takes place in the receiver side with the help of the same key. Among all these data flow methods, the optimal key selection is the critical issue that needs to be overridden to make the data transmission secured. As a novelty, a new optimization algorithm referred to as Whale with New Crosspoint-based Update (WNU), which is the advanced version of Whale Optimization Algorithm (WOA), is developed here to select the optimal key. Finally, the proposed WNU model is analyzed in terms of Hiding Failure (HF) rate, Information Preservation (IP) Rate, and False Rule generation (FR), and Degree of Modification (DM). The proposed secured information sharing in supply chain management (SCM) with blockchain technology will be validated by comparing it over the traditional models in terms of security as well.

Parallel crop planning based on price forecast

“…While the planning system provides the recommendation to farmers, the decision of farmers, the actual planting and harvest dates, planting area, and the final yield are preferably noted and give feedback for evaluation. Such information should be part of a product tracing system that can promote the reliability of the product; application of block train techniques 55,56 help further in building the transparency of field production. Otherwise, the field activity remains black-box as it is, which causes information inconsistency for markets and third-party service (e.g., insurance).…”

Enhancement of an Optimized Key for Database Sanitization to Ensure the Security and Privacy of an Autism Dataset

“…Abidi MH et al [26] established a secured data transmission model as Whale with New Crosspoint-based Update (WNU) in supply chain management along with blockchain technology. They also evaluated their model concerning four research issues, namely false rule generation (FR), the information preservation (IP) rate, the hiding failure (HF) rate, and the degree of modification (DM).…”

“…In addition, some of these traditional meta-heuristics algorithms also possess lower solving precision, slower convergence, and worse local searching ability. Moreover, we identified certain critical issues in the existing studies [5,6,[24][25][26] which we addressed, thus forming the focus of our research contributions. Such critical issues, put in question form, include, but are not limited to, the following:…”

Differential Game Model of Information Sharing among Supply Chain Finance Based on Blockchain Technology

“…At present, most studies on blockchain technology in supply-chain finance adopt various analytical methods such as literature analysis, qualitative analysis, and evolutionary game [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. These studies analyze the application of blockchain technology in the supplychain finance models, development situations, and the benefit distribution of supply-chain members.…”
