Data sharing mechanism of various mineral resources based on blockchain

Yili REN, Jia LIANG, Jian SU, Gang CAO, He LIU

《工程管理前沿（英文）》 2020年第7卷第4期页码 592-604 doi: 10.1007/s42524-020-0132-2

摘要： Basins with various mineral resources coexisting and enriching often occupy an important strategic position. The exploration of various mineral resources is repetitive at present due to unshared data and imperfect management mechanism. This situation greatly increases the cost of energy exploitation in the country. Traditional data-sharing mode has several disadvantages, such as high cost, difficulty in confirming the right of data, and lack of incentive mechanism, which make achieving real data sharing difficult. In this paper, we propose a data-sharing mechanism based on blockchain and provide implementation suggestions and technical key points. Compared with traditional data-sharing methods, the proposed data-sharing mechanism can realize data sharing, ensure data quality, and protect intellectual property. Moreover, key points in the construction are stated in the case study section to verify the feasibility of the data-sharing system based on blockchain proposed in this paper.

一种基于Chaum-Pedersen协议的欺骗可检测云存储数据共享协议 Research Papers

Xin WANG, Bo YANG, Zhe XIA, Hong-xia HOU

《信息与电子工程前沿（英文）》 2019年第20卷第6期页码 787-800 doi: 10.1631/FITEE.1800066

摘要：随着云计算技术的发展，数据可外包给云，方便用户共享。然而，用户常常担心其数据在云端的可靠性和完整性。因此，在云端提供安全的数据共享服务至关重要。本文将门限秘密共享技术和Chaum-Pedersen零知识证明相结合，提出一种可靠、安全的云数据共享方案。该方案不仅有效、灵活、语义安全，还能有效识别行为不诚实的欺骗者身份，确保合法用户解密密钥的安全。相比而言，该方案计算性能较好，尤其适合云端用户医疗保险数据保护。

“信息阳光”——无冲突共享结构

李幼平

《中国工程科学》 2000年第2卷第1期页码 24-27

摘要：

文章探讨一种非Internet原理的无冲突信息共享结构——“信息阳光”。“信息阳光”包含“数据流环境”和“个人需求代码”两个新概念。所谓“数据流环境”，是利用DVB技术，营造一种普照天下的高速数据流，每天都有数百GB的数据流经家庭。其流量如此之大，足以把上千种报纸、期刊、网站、课程的内容每天反复传播几十遍。所谓“个人需求代码”用来在上述数据流中辨认并下载用户有兴趣的内容，实现无需远程互联的交互选择。由于只需单向广播，大大降低了成本，也从原理上消除了互联结构固有的带宽冲突。

RCDS: 一种基于符号映射编码和区块链的可确权数据共享模型 Research Article

王亮1,黄顺久1,左立娜1,李军2,刘文远3

《信息与电子工程前沿（英文）》 2023年第24卷第8期页码 1194-1213 doi: 10.1631/FITEE.2200659

摘要：数据确权问题是数据共享中长期存在的瓶颈。现有数据确权方法由于缺乏有效监管手段可信度低，且由于技术限制只能用于特定数据类型。随着区块链的出现，一些新的数据共享模型有望提供更可靠的数据安全性。然而，因为数据访问不能完全处于区块链设施的控制下，这些模型在数据确权方面的能力不足。提出一种名为RCDS以符号映射编码（SMC）和区块链为特征的可确权数据共享模型。通过SMC，数据共享各方通过生成符号映射表将其数字身份嵌入被共享数据字节序列中，从而使数据权利的声明与数据类型和数据量无关。通过区块链，所有数据共享方共同监督数据的交付和访问，从而可公开验证数据权利的授予。评价结果表明，RCDS在强调确权要求的数据共享应用中是有效且实用的。

Reducing CO emissions from the rebalancing operation of the bike-sharing system in Beijing

《工程管理前沿（英文）》 2023年第10卷第2期页码 262-284 doi: 10.1007/s42524-021-0168-y

摘要： With the development of the bike-sharing system (BSS) and the introduction of green and low carbon development, the environmental impacts of BSS had received increasing attention in recent years. However, the emissions from the rebalancing of BSS, where fossil-fueled vehicles are commonly used, are usually neglected, which goes against the idea of green travel in a sharing economy. Previous studies on the bike-sharing rebalancing problem (BRP), which is considered NP-hard, have mainly focused on algorithm innovation instead of improving the solution model, thereby hindering the application of many existing models in large-scale BRP. This study then proposes a method for optimizing the CO₂ emissions from BRP and takes the BSS of Beijing as a demonstration. We initially analyze the spatial and temporal characteristics of BSS, especially the flow between districts, and find that each district can be independently rebalanced. Afterward, we develop a rebalancing optimization model based on a partitioning strategy to avoid deciding the number of bikes being loaded or unloaded at each parking node. We then employ the tabu search algorithm to solve the model. Results show that (i) due to over launch and lack of planning in rebalancing, the BSS in Beijing shows great potential for optimization, such as by reducing the number of vehicle routes, CO₂ emissions, and unmet demands; (ii) the CO₂ emissions of BSS in Beijing can be reduced by 57.5% by forming balanced parking nodes at the end of the day and decreasing the repetition of vehicle routes and the loads of vehicles; and (iii) the launch amounts of bikes in specific districts, such as Shijingshan and Mentougou, should be increased.

《工程（英文）》 2019年第5卷第4期页码 662-670 doi: 10.1016/j.eng.2018.12.013

摘要：

在工业领域，如何在多源工业数据的协作分析中保障源数据的私密性与安全性至关重要。本文提出了一种基于雾计算的工业大数据集成与共享方法（Fog-IBDIS），采用云端与边缘端协作的方式，实现工业数据的分布式本地处理，在多源数据的分析中保障源数据的私密性与安全性。首先，在云端设计了任务流图，将多源数据分析过程分解成多个子任务；其次，设计了子任务管理、编译和运行控制、数据集成传输、基本算法库和管理组件五个模块，实现子任务的本地边缘端处理；最后，本文以大型客机制造过程为例，对Fog-IBDIS的运行过程进行了验证，其通过边缘与云端的协作方式，将多来源数据分析任务分解至本地执行，通过中间结果的传输串联实现工业大数据的分析，可保障原始数据的私密性与安全性。

Interaction behavior and load sharing pattern of piled raft using nonlinear regression and LM algorithm-based

《结构与土木工程前沿（英文）》 2021年第15卷第5期页码 1181-1198 doi: 10.1007/s11709-021-0744-6

摘要： In the recent era, piled raft foundation (PRF) has been considered an emergent technology for offshore and onshore structures. In previous studies, there is a lack of illustration regarding the load sharing and interaction behavior which are considered the main intents in the present study. Finite element (FE) models are prepared with various design variables in a double-layer soil system, and the load sharing and interaction factors of piled rafts are estimated. The obtained results are then checked statistically with nonlinear multiple regression (NMR) and artificial neural network (ANN) modeling, and some prediction models are proposed. ANN models are prepared with Levenberg–Marquardt (LM) algorithm for load sharing and interaction factors through backpropagation technique. The factor of safety (FS) of PRF is also estimated using the proposed NMR and ANN models, which can be used for developing the design strategy of PRF.

Collaborative adoption of blockchain technology: A supply chain contract perspective

《工程管理前沿（英文）》页码 121-142 doi: 10.1007/s42524-022-0239-8

摘要： The outbreak of COVID-19 has significantly affected the development of enterprises. In the post-pandemic era, blockchain technology has become one of the important technologies to help enterprises quickly gain market competitiveness. The heavy investment required of supply chain stakeholders to employ blockchain technology has hindered its adoption and application. To tackle this issue, this study aims to facilitate the adoption of blockchain technology in a supply chain consisting of a core enterprise and a small/medium-sized enterprise through an effective supply chain contract. We analyze the performance of a cost-sharing (CS) contract and a revenue-sharing (RS) contract and propose a new hybrid CS-RS contract for better performance. We conduct comparative analyses of the three contracts and find that the hybrid CS-RS contract can more effectively incentivize both parties to reach the highest level of blockchain technology adoption and achieve supply chain coordination.
