【Abstract】In order to improve traffic conditions and environmental pollution caused by automobile exhaust, it is critical and challenging to help numerous vehicle users to obtain ideal parking spaces in terms of quality of experience (QoE), security and efficiency. The parking assistance scheme using the consortium blockchain can get a tradeoff between security and efficiency, but it is a key issue to meet the preferences of parking space seekers and design a well-operated incentive sharing mechanism. This paper proposes a Parking Assistance Alliance (PAA) scheme based on double auction for vehicular blockchain. Through truthful incentives, the PAA encourages vehicles in the alliance to provide parking information for nearby vehicle users. Further, the vehicle user's preference is fully considered when assigning the parking space. The matching priority is introduced by incorporating the parking space supply and demand, as a reference to provide prioritized service. Theoretical proofs and simulation results show that the PAA scheme can achieve individual rationality, budget balance, and truthfulness, with high user satisfaction, and the PAA scheme deployed on the IBM Hyperledger Fabric platform outperforms the existing method with an average of 7.42% higher successful allocation ratio and 35.4% less transaction confirmation time.

【Abstract】We investigate the puzzle of widespread participation in cryptocurrency pump-and-dump manipulation schemes. Unlike stock market manipulators, cryptocurrency manipulators openly declare their intentions to pump specific coins, rather than trying to deceive investors. Puzzlingly, people join in despite negative expected returns. In a simple framework, we demonstrate how overconfidence and gambling preferences can explain participation in these schemes. Analyzing a sample of 355 cases in 6 months, we find strong empirical support for both mechanisms. Pumps generate extreme price distortions of 65% on average, abnormal trading volumes in the millions of dollars, and large wealth transfers between participants.

【Abstract】Distributed Ledger Technology (DLT) is highly applicable in various fields, especially the supply chain in many sectors. Against limited empirical evidence, this paper analyzes the relations between the Kensho Distributed Ledger Technology Index and stock indices of 12 sectors, including communication services, consumer discretionary, consumer staples, energy, health care, financials, industrials, information technology, materials, utilities, and real estate, and ESG by employing the quantile coherency and dynamic connectedness techniques. Our results reveal that the quantile coherency between the DLT stock index and the sectoral stock indices in almost all cases is significant and positive. The positive co-movement tends to be stronger in the longer terms and as we move from the lower to the higher quantiles, implying that they are more strongly connected in the long term and during the bearish market condition. Moreover, the dynamic connectedness indicates that the DLT stocks and the sectoral stocks are highly connected, with the former being a net transmitter of spillover shocks. The spillovers are also time-varying, and the results significantly corroborate those of the quantiles coherency methods. Among other relevant implications, DLT can be an important factor in the development and enhancement of these sectors.

【Abstract】The use of Blockchain is becoming a matter of increasing importance, yet the software development industry has not given Blockchain adoption enough consideration. As a result of their inability to modify their software process within the project life cycle, many software development companies struggle to [adopt Blockchain technology. This is because Blockchain Oriented Software (BOS) and its projects have distinctive characteristics that are distinct from traditional software and projects. The constructs and their items to adopt Blockchain in Software development industry have not been identified or investigated. This study aimed to identify technological, organizational, and environmental constructs and their items to adopt Blockchain. Utilizing a quantitative validation approach, 10 interviews and 25 assessment questionnaires were analyzed. The results reveal the identified technological, organizational, and environmental constructs and their items to adopt Blockchain. Experts unanimously agreed with Content Validity Ratio (CVR) results. According to most evaluation questionnaire forms and interview transcripts, the top technological construct was "Trialability" and the top organizational construct was "Cost" while the top environmental construct was "Market Dynamics." All other constructs and their items were applicable, as indicated by most evaluation questionnaire forms and interview transcripts. This research gives a comprehensive list of technological, organizational, and environmental constructs and their items that demand the attention of Blockchain adoption researchers and industry players in the software development sector.

【Abstract】This paper investigates how blockchain technology may alter the defining mechanisms of residential real estate transactions in Sweden. It departs from the assumption that blockchain applications do not merely change complex socio-economic, organisational and governance arrangements of mature housing and mortgage markets. Rather, they may trigger resistance among incumbents in the current organisational model, which will drive incremental change. This analysis shows that housing transactions in Sweden are long and complex endeavours, underpinned by exclusivity, uncertainty and information inequalities. A public-private consortium led by Lantmateriet - a Swedish government agency - has pioneered the use of blockchain technology for the conveyance of a house to address these deficiencies. This project has not moved beyond the proof-of-concept phase, while the socio-technical organisation of transactions has evolved. Insights from institutional and evolutionary approaches help conceptualise how technologically induced and qualitatively different structures and functional effects may change the way housing and mortgage markets will work, thereby highlighting both disruptive potentialities and limitations of blockchain applications for the legacy design underpinning the current Swedish housing transaction system. Following a forensic empirical approach, this paper dissects the organisational architecture, key practices and the linked network of actor groups running Sweden's property and mortgage markets. Results illustrate that understanding concrete blockchain-induced changes and their unintended consequences requires closer scholarly attention at the scale of actor networks, the types of knowledge and technologies, and the micro-geographies in which they are embedded. Such in-depth understanding enables better-informed assessments of the blockchain challenge for complex housing and mortgage markets.

【Abstract】Digital technologies affect all areas and activities of society. Accounting is no exception to this trend, as organizational information system accounting increasingly integrates digital technologies. The paper aims to study the integration of ethical requirements with the quality requirements in implementing digital technologies based on artificial intelligence, blockchain, the internet of things, and cloud computing in financial and managerial accounting. This empirical study of 396 accountants from Romanian organizations involves investigating the influence of ethical and quality requirements of digital technologies on the perception of users' satisfaction in financial and managerial accounting. Empirical research encompasses a quantitative approach using structural equation modeling and artificial neural network analysis in a two-stage procedure. Some of the existing ethical issues can be addressed by implementing new digital technologies but implementing these emerging technologies can generate other ethical and quality issues that accounting and IT professionals must address in a combined effort. The research results show that the ethical requirements that influence the perception of financial and managerial accounting are security and trust. Among the quality requirements, the most critical influence in the perception of accountants is reliability.

【Abstract】The majority of medical equipment in use today does not have built-in security features. As a result, whether linked to a hospital system or the cloud, these devices' built-in weaknesses make them vulnerable to a variety of cyberattacks. In hospitals and clinics, hackers can breach equipment, manipulate data, and disrupt facilities, putting patients' health as well as their lives in jeopardy. A professional can manage cybersecurity threats by lowering the attack surface of the system. Security analysis, whether as a means to detect possible vulnerabilities that can be exploited by attackers or as a means to prevent cyberattacks, plays an important role in risk mitigation. In addition, throughout the pre-market and post-market phases, security checks are required. This study presents a paradigm for incorporating security check concepts into medical device design and development and healthcare big data security. The security of devices and healthcare data is tested by the integrated fuzzy AHP-TOPSIS method. After the security check of devices, with the parameters security-checked for data, the algorithm is designed and implemented. As a result, the appropriate customized security controls are prompted in order to impede the attack.

区块链技术-平台项目-Hyperledger Fabric

【Abstract】The Internet of Things (IoT) is an integrated environment as it merges physical smart objects to the Internet via wireless technologies to share data. The global connectivity of IoT devices brings the needs to ensure security and privacy for data owners and data users. In this paper, an attribute-based access control scheme for IoT (AAC-IoT) using Hyperledger Fabric (HLF) blockchain is proposed to address the security challenges. In the AAC-IoT scheme, data owners are registered and authenticated using identities, certificates and signatures. Data users, however, are registered with identities, certificates, signatures and physical unclonable function (PUF); then a credence score is computed for users to predict the originality during authentication. For access control, attribute-based access control (ABAC) is used, and the number of attributes is selected based on the sensitivity of the data. In accordance with the attributes count, the access control policies are generated. The novel concept of attribute count is determined from a fuzzy logic method using data type and preference. Hyperledger Fabric (HLB) blockchain is presented to manage meta-data and security credentials from data owners and data users, respectively, using a lightweight hashing algorithm. The AAC-IoT model using HLF blockchain is developed with Java programming language and iFogSim simulator. The performance metrics are measured based on latency, throughput and storage overhead, and the results show better outcome than the previous research work.

【Abstract】The Internet of Medical Things (IoMT) global market has grown and developed significantly in recent years, and the number of IoMT devices is increasing every year. IoMT systems are now very popular and have become part of our everyday life. However, such systems should be properly protected to preventing unauthorized access to the devices. One of the most popular security methods that additionally relies on real-time communication is Blockchain. Moreover, such a technique can be supported by the Trusted Third Party (TTP), which guarantees data immutability and transparency. The research and industrial community has predicted the proliferation of Blockchain-based IoMT (BIoMT), for providing security, privacy, and effective insurance processing. A connected environment comprises some of the unique features of the IoMT in the form of sensors and devices that capture and measure, recognize and classify, assess risk, notify, make conclusions, and take action. Distributed communication is also unique due to the combination of the fact that the Blockchain cannot be tampered with and the Peer-to-Peer (P2P) technique, especially compared to the traditional cloud-based techniques where the reliance of IoMT systems on the centralized cloud makes it somewhat vulnerable. This paper proposes a Blockchain-based technique oriented on IoMT applications with a focus on maintaining Confidentiality, Integrity, and Availability (the CIA triad) of data communication in the system. The proposed solution is oriented toward trusted and secure real-time communication. The presented method is illustrated by an example of a cloud-based hospital application. Finally, the security aspects of the proposed approach are studied and analyzed in detail.

【Abstract】In the traditional teaching mode, teachers have limited time and energy, but the emergence of AI technology-assisted teaching has greatly facilitated students and teachers. They can study and teach anytime and anywhere and can also solve the problem of lack of professional teachers or venues. With the continuous popularization of "Internet + education" technology, the teaching mode has changed, and online courses are gradually accepted by students regardless of time and geographical constraints. This article aims to study the optimization and application of the intelligent scheduling algorithm in the physical education management system based on blockchain technology. This article proposes a combination of Edge Computing technology and intelligent algorithm software and hardware to improve the current difficulties of domestic colleges and universities. The core content of integration, system functions, course scheduling algorithm, database, and other core contents are preliminary designed, hoping to provide ideas for the specific implementation of the college course scheduling system. The experimental results in this paper show that with the support of Edge Computing in solving the CSP problem, the efficiency of various algorithms is relatively high and comparable when the filling rate is less than 90%. However, when the filling rate exceeds 90%, the execution time of the IFS CBS algorithm is relatively longer, but it is generally acceptable. The algorithm and optimization strategy are also implemented, and the performance improvement of the algorithm is compared and analyzed through experiments, which proves the feasibility of the optimization strategy.

【Abstract】Jingdezhen ceramic heritage is the largest existing ceramic cultural heritage in China, with the richest connotation and the most complete system. It has the characteristics of strong systematization, complicated preservation, and diversified use. With the vigorous development of cultural industry, Jingdezhen's ceramic heritage has a broad application prospect, but at the same time, it faces the problem of being destroyed or improperly developed. With the progress of science and technology and the development of machinery, the traditional hand-made porcelain technology of Jingdezhen ceramics is gradually being eliminated. The value and distinctive feature of Jingdezhen ceramic heritage is the importance and necessity of its protection, and the protection of Jingdezhen ceramic heritage has become an urgent problem to be solved. In order to solve this problem, this paper takes the protection of Jingdezhen ceramic heritage as the research object, analyzes the characteristics and protection status of Jingdezhen ceramic heritage, and applies blockchain technology to the protection of Jingdezhen ceramic heritage, which promotes the protection of ceramic heritage. The decentralized, traceable, and open characteristics of blockchain technology provide innovative technical support for the digital construction of ceramic heritage and strong technical support for the protection of ceramic heritage. The results show that by analyzing the current situation of Jingdezhen ceramic heritage protection and construction, the digital model of Jingdezhen ceramic heritage based on blockchain technology is established by combining blockchain technology with digital construction of ceramic heritage, and a digital identity is built for Jingdezhen ceramics. The collected Jingdezhen ceramic information is attached to the blockchain, which ensures its unique and effective identity information, realizes the integration of Jingdezhen ceramic information, and actively promotes the informatization and standardization of ceramic heritage protection. The research results provide new ideas for Jingdezhen ceramic heritage protection and theoretical support for heritage protection and inheritance.

【Abstract】In the past few years, ride-hailing platforms such as Uber, Waymo, and Baidu have built their own autonomous taxi system. Unlike public transit services, ride-hailing platforms raise severe privacy issues. To provide excellent autonomous taxi service, some significant security and privacy problems must be addressed. In this study, we present the security and privacy threats and first proposed blockchain-based anonymous ride-hailing scheme (BBARHS) for autonomous taxi network. We give the formal system model and security model of BBARHS. Then, we outline the concrete BBARHS scheme by making use of Monero and some efficient crypto tools. Through security analysis and performance analysis, the designed scheme is provably secure and efficient. The analysis results also show the designed BBARHS scheme is practical for autonomous taxi network.

【Abstract】Quality management is one of the most critical issues in supply chain management. The rapid growth of information technologies, such as blockchain technology, has facilitated effective information systems development to support supply chain quality management. However, a significant challenge in developing blockchain-enabled supply chain quality information systems is how to deal with information asymmetry and the conflicting interests of supply chain partners. Taking a service-dominant view, this research proposes a Blockchain-Oriented Service Modeling (BOSM) approach for blockchain-enabled supply chain quality information systems. We provide a visual language for modeling the coordination and integration of business processes and domain knowledge at the knowledge level to facilitate the alignment of blockchain technology with supply chain quality management. The proposed approach bridges operational service computing with strategic service management in blockchain-enabled supply chain quality management and facilitates the communication between business people in supply chain management and software professionals in blockchain-based service computing. A case study on a dairy supply chain is presented to show advantages of the modeling framework under the service-dominant view, separating the cause of quality from the carrier of quality in the design of blockchain-enabled supply chain quality information systems.

【Abstract】Digitalization of financial institutes, industries, and organizations to provide fast online services needs a large number of Internet connections and different types of networks. The presence of a large number of digital networks makes operational communication and data transfer vulnerable to different cyber-attacks. So, to secure the system, there must be a mechanism present to detect malicious activities and give an alarm to the operator/HMI. A numerous intrusion detection system is present in this era but still, the intruders get access to the network and create an economical loss. Blockchain is a new path to gain the trust in the cyber-security field. Researchers have been working on the term "blockchain technology" for the past few years. In a growing digital environment, blockchain is a novel technology that provides various advantages. This paper identifies and examines the possible way to enhance the blockchain capability by integrating with principal component analysis (PCA). The bad data are removed from the real-time data set and then pass through the blockchain mechanism to identify the threats. The results of the investigation and analysis demonstrate that, when compared to the traditional approach, the PCA integration with the blockchain method proposed in this paper may reduce detection time and boost detection rate.

【Abstract】Water rights trading is an important way to solve the shortage of water resources. Combined with the characteristics of water resources and the requirements of the market economy, the organic combination of the government and the market should be strengthened. Through the establishment of a water rights system and a water rights trading market, the implementation of water rights trading will be promoted. Due to the decentralized and distributed structure, blockchain technology greatly reduces its intermediary cost in the application process. The tamper-resistant timestamp feature can realize data tracking and information anticounterfeiting, and flexible programming attributes can promote the specification of market order. Firstly, the reasons for water rights trading are studied, and the water rights trading system is analyzed. It is found that the system has the problems of the cumbersome transaction process and high transaction costs. According to the characteristics of water rights trading, the alliance chain Hyperledger Fabric is selected as the underlying network system of the trading system. Secondly, combined with water rights trading, Hyperledger Fabric multichannel technology is used to design a three-channel accounting method, and the chain code for water rights trading is designed and implemented based on the Go language. CouchDB is adopted to store key-value data, and Ubuntu, Docker, and Docker Compose are used to construct an operating environment of the chain code. Finally, the proposed system is tested. The test findings reveal that the distributed water volume of experimental area 1 is 41.8368 million m(3), the current water volume is 23.831 million m(3), and the quota management water volume is 20.432 million m(3). The distributed water volume in area 2 is 40.4605 million m(3), the current water volume is 4317.64 m(3), and the quota management water volume is 77.4795 million m(3). The distributed water volume in area 3 is 65.6928 million m(3), the current water volume is 77.472 million m(3), and the quota management water volume is 64.412 million m(3). The water rights trading system based on Hyperledger Fabric can record each transaction data, which can be stored in each node, and the data stored in each node are the same. The proposed scheme provides a certain reference for the application of blockchain technology in water rights trading in irrigation areas.

【Abstract】The surging development of modern information technologies such as cloud computing and blockchain has stirred up a revolution in the culture industry. In order to further integrate culture with technology, local governments continuously inject subsidies into the culture industry. With listed companies in the Chinese culture industry as the samples, we innovatively combine the life cycle, with technological innovation input and output. This study indicates that government subsidy can remarkably boost the input and output of technological innovation in the culture industry, which delivers a signaling effect to enhance the external financing of listed companies in the culture industry; during the process when government subsidy affects technological innovation activities in the culture industry, equity financing performs better in intermediate effect than bank loans; in the culture industry, government subsidy has a stronger impact on the technological innovation input of growing listed companies and the technological innovation output of advanced listed companies; for growing enterprises in the culture industry, equity financing delivers a strong mediating effect between government subsidy and scientific and technological innovation capacity.

【Abstract】Internet of Things (IoT) is considered the upcoming industrial and academic revolution in the technological world having billions of things and devices connected to the Internet. These connected devices are heterogeneous. They have different standards and technologies which communicate through different protocols. Therefore, the implementation of IoT on a large scale is difficult due to these heterogeneity challenges. This motivated us to overcome the scaling problem of IoT by identifying the challenges from the literature and providing solutions. This study is based on the identification of the heterogeneous challenges with solutions via a systematic literature review. A total of 81 primary sources were selected. After extracting and synthesizing the data, we identified 14 different IoT heterogeneity challenges. Some of the identified challenges are "heterogeneity of devices," "heterogeneity in formats of data," "heterogeneity in communication," and "interoperability issue due to heterogeneity." The identified challenges have been analyzed from digital libraries and timeframe perspectives. Furthermore, we have found a total of 81 solutions for those challenges, with at least 5 unique solutions for each challenge. In the future, we will categorize the challenges and prioritize the solutions by using a multi-criteria decision-making problem.

【Abstract】The Sustainable Development Goals of the United Nations prioritize sustainability by 2030. The fashion industry is one most substantial manufacturing industries that generate an economy of 3 trillion dollars and contributes to 2% of the world's gross domestic product. In addition to this, the fashion industry must focus on social and environmental concerns, where it should create fashionable products to promote sustainable consumption and production. Sustainable consumption and production can be achieved with the establishment of resilient infrastructure with innovation. The resilient infrastructure with innovation is realized by the integration of digital technologies such as the Internet of Things (IoT), artificial intelligence (AI), blockchain, augmented reality (AR), and virtual reality (VR). With this motivation, this study explored the different studies that implemented these technologies in the fashion industry for smart cloth (health), supply chain, circular economy, dress recommendation system, fashion trend forecasting, health prediction, and virtual and augmented based shopping experience. Along with the progress of these technologies in the fashion industry, the study also discussed limitations and provided recommendations such as wide adoption of blockchain in fashion supply chain; advancement in energy storage for smart cloth; integration of IoT, AI, and edge computing; and smart clothing-based framework for rescue operation for future enhancement.

区块链应用-虚拟经济-NFT

【Abstract】This paper will first describe some of the unique features of blockchain technology and 'smart contracts' used in NFTs. Next, we discuss four ways in which the economic and social potential of NFTs can be derailed, leading to 'digital enclosures' whereby large institutional copyright holders reap most of these benefits for themselves through illegitimate - and sometimes unlawful rent-seeking, as well as the very real potential for fraudulent activities by malicious actors. Finally, we offer some initial suggestions on how to regulate NFTs and blockchain technology to prevent these illegitimate forms of rent-seeking and the 'digital enclosures' to which they give rise. Future governance in this area should be directed toward protecting individual artists, content creators, and small businesses over large institutional copyright holders, as do many current laws and regulations.
