Blockchain-Enabled Decentralized Secure Big Data of Remote Sensing

Abstract

Blockchain technology has emerged as a promising candidate for space exploration and sustainable energy systems. This transformative technology offers secure and decentralized strategies to process and manipulate space resources. Remote sensing provides viable potential with the coexistence of open data from various sources, such as short-range sensors on unmanned aerial vehicles (UAVs) or Internet-of-Things (IoT) tags and far-range sensors incorporated on satellites. Open data resources have most recently emerged as attractive connecting parties where owners have shown consent to share data. However, most data owners are anonymous and untrustworthy, which makes shared data likely insecure and unreliable. At present, there are several tools that distribute open data, serving as an intermediate party to link users with data owners. However, these platforms are operated by central authorities who develop guidelines for data ownership, integrity, and access, consequently restricting both users and data owners. Therefore, the need and feasibility of a decentralized system arise for data sharing and retrieving without involving these intermediate limiting parties. This study proposes a blockchain-based system without any central authority to share and retrieve data. Our proposed system features (i) data sharing, (ii) maintaining the historical data, and (iii) retrieving and evaluation of data along with enhanced security. We have also discussed the use of blockchain algorithms based on smart contracts to track space transactions and communications in a secure, verifiable, and transparent manner. We tested the suggested framework in the Windows environment by writing smart contracts prototype on an Ethereum TESTNET blockchain. The results of the study showed that the suggested strategy is efficient, practicable, and free of common security attacks and vulnerabilities.

The effect of Blockchain technology as a moderator on the relationship between big data and the risk of financial disclosure (analytical study in the Egyptian and Iraqi stock exchange)

“…Compared to [10,30,41,42] have indicated the relationship between big data and blockchain technology indicating that this study contributed to addressing the risks of financial disclosure through the use of blockchain technology as an independent variable in protecting big data.…”

“…Besides, according to [30] proposes a blockchain-based system without any central authority to share and retrieve data. Our proposed system features:…”

“…As well, in Table 1 shows the convergent validity is assessed by examining its average variance extracted (AVE) value. According to [30], convergent validity is assessed with individual items that reflect a construct converging in comparison of items measuring with different constructs. In PLS, convergent validity is evaluated by measuring the values of Average Variance Extracted (AVE).…”

“…Security vulnerabilities in these devices may lead to unauthorized access to sensitive information. For Instance, sensors deployed in the field may encounter the risk of physical accessibility, making them vulnerable to tampering, damage, or theft, eventually leading to compromised data accuracy and possible disruptions to the system [206]. Threats related to privacy: Farmers face potential issues with the ownership and control of their data.…”

“…Decentralized storage, commonly referred to as distributed ledger storage, is a feature of blockchain-based solutions that enables users to store their data on other network nodes autonomously. The issue is that network nodes have a finite amount of processing and storage capacity [ 6 , 7 ].…”
