Survey: federated learning data security and privacy-preserving in edge-Internet of Things

AbstractThe amount of data generated owing to the rapid development of the Smart Internet of Things is increasing exponentially. Traditional machine learning can no longer meet the requirements for training complex models with large amounts of data. Federated learning, as a new paradigm for training statistical models in distributed edge networks, alleviates integration and training problems in the context of massive and heterogeneous data and security protection for private data. Edge computing processes data at the edge layers of data sources to ensure low-data-delay processing; it provides high-bandwidth communication and a stable network environment, and relieves the pressure of processing massive data using a single node in the cloud center. A combination of edge computing and federated learning can further optimize computing, communication, and data security for the edge-Internet of Things. This review investigated the development status of federated learning and expounded on its basic principles. Then, in view of the security attacks and privacy leakage problems of federated learning in the edge Internet of things, relevant work was investigated from cryptographic technologies (such as secure multi-party computation, homomorphic encryption and secret sharing), perturbation schemes (such as differential privacy), adversarial training and other privacy security protection measures. Finally, challenges and future research directions for the integration of edge computing and federated learning are discussed.

On the Transmission Mechanism of Carbon Finance Promoting the Green Transformation of Traditional Industries in China

This article clarifies the specific impact mechanism of carbon finance on the industrial transformation of Anhui Province in China by studying the changes in carbon emissions and the current status of industrial development in Anhui. Through research and investigation, it has been found that the impact of carbon finance on industrial transformation is mainly reflected in four aspects: (1) Carbon finance enables some enterprises to have more funds to improve production processes and reduce carbon emissions in the production process through carbon emission trading. (2) Carbon finance promotes its transformation by changing the operating mechanism of the market, lowering entry barriers, and allowing more enterprises to enjoy the dividends of carbon finance. (3) Carbon finance uses financial means to eliminate high energy consuming and high emission enterprises and optimize industrial structure. (4) The emergence of carbon finance will encourage the government to increase support for financial related talents, cultivate more talents in carbon finance, change the management mode of enterprises, and enhance their international competitiveness. This article proposes countermeasures and suggestions from the perspective of promoting environmental protection and industrial green transformation and development.

Research on the Level of Synergistic Development of Supply and Demand in China’s Health Industry

This study combines the latest vague set similarity measurement method with the entropy weight TOPSIS method; furthermore, it applies the grey relational analysis method to establish a model for the synergistic development of supply and demand in the health industry, and it empirically analyzes the development status, synergy level, and synergistic development level of China’s health industry supply and demand from 2013 to 2021. The findings reveal that: (1) China’s health industry supply maintains steady growth, while demand grows rapidly. However, the overall level of supply and demand development is generally low, indicating significant potential for future development. Moreover, the development of the supply lags behind that of the demand, leading to an increasing gap year by year. (2) The level of synergy between supply and demand in China’s health industry is relatively high but is decreasing year by year. Although the degree of synergistic development between supply and demand continues to increase, it remains at a low level, indicating that high coordination between supply and demand comes at the cost of a low development level. (3) There exists a significant regional imbalance in the development of China’s health industry, with the overall difference showing a widening trend year by year. Regional disparities are the main source of the overall difference.

Coordinated development of island ecotourism: A comprehensive evaluation of Amami-Oshima Island

Island tourism has garnered growing attention especially with the rapid expansion of ecotourism in island destinations. While past research has explored the integrated development of island tourism, environment, and economy, there exists a demand for a more comprehensive exploration that incorporates social aspects. This study aimed to establish a comprehensive evaluation index system for island ecotourism using Amami-Oshima Island as an example. It uses four tourism subtypes, including environment, economic, social, and other-sector tourism, within the framework for island ecotourism. We employed a Coupling Coordination Degree Model and a Grey Verhulst model, utilizing data from Amami-Oshima Island from 2010 to 2021 as a basis for quantitative analysis of the current status of island ecotourism coupling coordination development and for making predictions. The research outcomes reveal the following: (1) Between 2010 and 2021, Amami-Oshima Island exhibited an overall upward trajectory in the comprehensive development of ecotourism. The environment-tourism subsystem demonstrated robust performance, the social-tourism subsystem displayed fluctuating growth, and the economic and the other-sector tourism dimensions generally progressed in tandem. (2) The coupling degree and coordination level of Amami-Oshima Island ecotourism showed an overall upward trend, with coordination evolving from a state of minimal coordination to an intermediate level. However, opportunities remain to enhance high-quality coordination through mutual influences and interdependencies. (3) Predictions indicate a slight increase in ecotourism coupling coordination on Amami-Oshima Island over the next nine years (2022–2030). Based on these findings, this paper presents several policy recommendations, serving as a guideline for ecotourism development on Amami-Oshima Island. The research results carry significant implications for understanding the present status and future trends of ecotourism on Amami-Oshima Island and offer valuable policy suggestions for the development of ecotourism on other islands.
