In the era of global social media, Internet users’ privacy rights have been weakened, and the insight and alertness of individuals for privacy disclosure are decreasing. The security and flexibility of the system are usually the two ends of the measurement standard. While more and more users pursue the intelligence and convenience of using social media applications, letting big data technology and AI algorithms learn and use our privacy data cannot be avoided. On the basis of literature review, this paper summarized four categories of social media user behavior, which were divided into privacy concern behavior, privacy protection behavior, active disclosure behavior, and passive participation behavior. Using analytic hierarchy process, this paper explored their relationship with five different types of privacy: defensive privacy, identity authentication privacy, interactive privacy, psychological privacy, and integration information privacy. We finally formulated the most common twelve kinds of sub-internet user behavior on the degree of personal privacy disclosure, and provide users countermeasures to prevent privacy disclosure according to the different influence weights.

It is undeniable that most business organizations rely on the Internet to conduct their highly competitive businesses nowadays. Cyber security is one of the important elements for companies to guarantee the normal operation of their business activities. However, there is no panacea in cyber security protection. Common security practices used are to deploy hardware and software security protection tools to combat the known security threats which may become more and more powerful later. In fact, the attackers and security practitioners are at war from time to time. As a result, such a tools-based security protection strategy cannot be sustained. On the other hand, the related awareness training for employees is ignored in a number of companies, which has made biased the decisions made by staff when facing cyber security breaches. In this study, in order to find ways to sustain such protection, we conduct a quantitative analysis to explore the key elements contributing to the SETA implementation of the companies and organizations. We evaluate the performances of eight supervised learning models in a dataset collected from cyber security breach surveys on UK businesses to perform a fundamental analysis. The detailed analysis is performed via the feature importance of features generated in the model with better performance in the task of detecting the companies and organizations with SETA implementation. The experiment result shows that the awareness related factors play the most significant role in the SETA implementation decision-making for the businesses, and most of the businesses are lacking the awareness to prevent the potential cyber security risks in the stuff using externally-hosted web services and products as well as services depending on online services.

This article looks at studies on how to use business continuity management for Hong Kong’s virtual banks in order to reduce customer information risks, so as to maintain business sustainability. Firstly, the development of virtual banks in Hong Kong were investigated, the laws and regulations and regulatory policies of Hong Kong and the Mainland were benchmarked, and the main risks that may occur and be harmful to the bank business sustainability were analyzed. Considering the characteristics of virtual banks, the main concerns of public customers about the IT risks of virtual banks through questionnaire surveys were collected and analyzed. Moreover, the importance of business continuity management to virtual banks was drawn. Secondly, in the case studies, via understanding the overall situation of WeBank, its performance during the COVID-19 pandemic, and the regulations of the Monetary Authority of Singapore, the practice standards of virtual banks in business continuity management were further clarified. At the end, three suggestions for virtual banks in Hong Kong were put forward to reduce customer information security risks through business continuity management, thereby maintaining its business sustainability.

Information systems misuse and data breaches are among the most common information security threats at the organisational and individual levels. Security, Education, Training and Awareness (SETA) program can be effective tools in addressing and preventing such risks for sustaining the educational sector’s information security, although it is costly to implement and achieves limited results. Several studies have shown that SETA implementation can improve corporate employees’ information security protection behaviours. This study adopts the method of quantitative research, deterrence theory with selected perceived cost and information security awareness (ISA) as intermediate variables and explores how SETA programs affect information system abuse on campuses. The results show that implementing the SETA program positively impacts perceived cost and ISA; perceived cost and information security positively impact reducing misuse behaviour of information systems. At last, we provide rationalisation suggestions for individual students and schools to help SETA programs to be better implemented.

Blockchain technology is now an advanced and innovative database technology and the attributes of blockchains are apparent in a variety of industries, especially in the financial industry. One of the most famous blockchain use cases, cryptocurrencies, has provoked much interest in social network users and customers. According to CoinMarketCap’s information, the global crypto market capitalization has reached around USD 2.37 T and there are around 9975 different cryptocurrencies available in the market. Despite the fact that academia and industry have paid much attention towards the blockchain direction, there is not much research on the factors that influence customer acceptability. This paper studies blockchains from a different angle, probing the factors prompting customers to use financial applications that utilize blockchain technology. We established the model and sorted the individual factors of perceived information security, technology awareness and privacy and found that users’ acceptance is significantly affected by information security and technology awareness, while privacy does not significantly influence users. According to the findings, we provide useful insights for application developers, conclude by presenting the limitations of the research and provide guidelines for future research.

In the age of digitalization, business-to-business (B2B) data sharing is becoming increasingly important, enabling organizations to collaborate and make informed decisions as well as simplifying operations and hopefully creating a cost-effective virtual value chain. This is crucial to the success of modern businesses, especially global business. However, this approach also comes with significant privacy and security challenges, thus requiring robust mechanisms to protect sensitive information. After analyzing the evolving status of B2B data sharing, the purpose of this study is to provide insights into the design of theoretical framework solutions for the field. This study adopts technologies including encryption, access control, data anonymization, and audit trails, with the common goal of striking a balance between facilitating data sharing and protecting data confidentiality as well as data integrity. In addition, emerging technologies such as homomorphic encryption, blockchain, and their applicability as well as advantages in the B2B data sharing environment are explored. The results of this study offer a new approach to managing complex data sharing between organizations, providing a strategic mix of traditional and innovative solutions to promote secure and efficient digital collaboration.
