Today’s data is sensitive that requires privacy and security both from the cloud service providers (CSP) as well as from users in its all the form of data states: data at rest, while transferring data, enquiring data, and processing the data. Cloud computing has been applied in the health sector, national security services, banking and other business and companies that store confidential data into the cloud as we have seen in recent years. Therefore, information and data security is a crucial issue that needs to be addressed thoroughly in the cloud computing business. This research deals with the performance analysis of recent cloud data security models. This paper proposes cloud data security models based on Business Process Modeling Notations (BPMN) and simulation results can reveal performances issues related to data security as part of any organizations initiative on Business process management (BPM). 相似文献

Despite mobile applications being at the frontier of mobile computation technologies, security issues pose a threat to their adoption and diffusion. Recent studies suggest that security violations could be mitigated through improved security behaviors and attitudes, not just through better technologies. Existing literature on behavioral security suggests that one of the main predictors of users’ perceptions of security is their perceived privacy concerns. Using communication privacy management theory (CPM), this study examines the effects of privacy-related perceptions, such as privacy risk and the effectiveness of privacy policies, on the security perceptions of mobile app users. To empirically test the proposed theoretical model, two survey studies were conducted using mobile apps requesting less sensitive information (n = 487) and more sensitive information (n = 559). The findings show that the perceived privacy risk negatively influences the perceived security of the mobile apps; the perceived effectiveness of a privacy policy positively influences user perceptions of mobile app security; and perceived privacy awareness moderates the effect of perceived privacy risk on the perceived security of mobile apps. The results also suggest that users have different privacy-security perceptions based on the information sensitivity of the mobile apps. Theoretical and practical implications are discussed. 相似文献

The advancement in mobile technology and the introduction of cloud computing systems enable the use of educational materials on mobile devices for a location- and time-agnostic learning process. These educational materials are delivered in the form of data and compute-intensive multimedia-enabled learning objects. Given these constraints, the desired objective of mobile learning (m-learning) may not be achieved. Accordingly, a number of m-learning systems are being developed by the industry and academia to transform society into a pervasive educational institute. However, no guideline on the technical issues concerning the m-learning environment is available. In this study, we present a taxonomy of such technical issues that can impede the life cycle of multimedia-enabled m-learning applications. The taxonomy is devised based on the issues related to mobile device heterogeneity, network performance, content heterogeneity, content delivery, and user expectation. These issues are discussed, along with their causes and measures, to achieve solutions. Furthermore, we identify several trending areas through which the adaptability and acceptability of multimedia-enabled m-learning platforms can be increased. Finally, we discuss open challenges, such as low complexity encoding, data dependency, measurement and modeling, interoperability, and security as future research directions. 相似文献

The mechanism of business analytics affordances enhancing the management of cloud computing data security is a key antecedent in improving cloud computing security. Based on information value chain theory and IT affordances theory, a research model is built to investigate the underlying mechanism of business analytics affordances enhancing the management of cloud computing data security. The model includes business analytics affordances, decision-making affordances of cloud computing data security, decision-making rationality of cloud computing data security, and the management of cloud computing data security. Simultaneously, the model considers the role of data-driven culture and IT business process integration. It is empirically tested using data collected from 316 enterprises by Partial Least Squares-based structural equation model. Without data-driven culture and IT business process integration, the results suggest that there is a process from business analytics affordances to decision-making affordances of cloud computing data security, decision-making rationality of cloud computing data security, and to the management of cloud computing data security. Moreover, Data-driven culture and IT business process integration have a positive mediation effect on the relationship between business analytics affordances and decision-making affordances of cloud computing data security. The conclusions in this study provide useful references for the enterprise to strengthen the management of cloud computing data security using business analytics. 相似文献

Increasing people are using mobile applications (apps) for information and activities related to their travel and tourism. Therefore, customer engagement (customer attraction and retention) with mobile travel applications becomes extremely important for travel-related companies. However, there is little empirical research on what factors may drive customers’ engagement of using mobile travel apps. This study proposes a research framework, based on the Stimulus-Organism-Response (S-O-R) model, to explore how and to what extent two types of app attributes (i.e., app design and app performance attributes) stimulate travel apps engagement. Based on a user acceptance testing (UAT testing) of a real travel app development project, the study uses survey data from 804 tourists to validate the proposed research model. The results reveal different effectiveness of app design and app performance attributes, and demonstrate that two app design features (i.e., user interface attractiveness and privacy/security) and three app performance attributes (i.e., compatibility, ease of use, and relative advantages) are important drivers of users’ behavioral engagement of mobile travel apps. Further, psychological engagement and three types of benefit perception (i.e., hedonic benefit, utilitarian benefit, and social benefit) serially mediate the relationships. The results can be used to improve the related mobile app engagement research and the mobile travel app design. 相似文献

Managing personal information such as to-dos and contacts has become our daily routines, consuming more time than needed. Existing PIM tools require extensive involvement of human users. This becomes a problem in using mobile devices due to their physical constraints. To address the limitations of traditional PIM tools, we propose a model of mobile PIM agent (PIMA) that aims to improve PIM on mobile devices through natural language interface and application integration. We conducted a user study to evaluate PIMA empirically with prototype systems. The results show that mobile PIMA improved perceived usefulness, ease-of-use, and efficiency of PIM on mobile devices, which in turn accounted for positive attitude and intention to use the system. The findings of this study provide suggestions for designing and developing PIM applications on mobile devices. 相似文献

Industry 4.0 places a premium on cloud security since more and more companies are moving their activities to the cloud to reap the benefits of the Fourth Industrial Revolution.The term “cloud computing” refers to a collection of Internet-based hardware and software tools. Providers of cloud services use data centers situated in various physical locations. Cloud computing makes life easier for users by making remote, simulated resources available over the internet. Google Apps and Microsoft SharePoint are two examples of popular cloud applications. In addition to its exciting potential, the “cloud computing” industry's lightning-fast expansion raises serious security concerns. When discussing security, cloud really suffers from Open Systems' and the internet's perennial problem. The only thing stopping the widespread use of cloud computing is the lack of trust in the system. There are a number of security concerns with cloud computing, including protecting user data and vetting cloud service providers' practices. Using encryption, confidential information can be sent over an unsecured channel without fear of data loss or manipulation. Data encryption using various protocols has been used in various settings. Different cryptosystems were developed and used at various times. Additionally, cloud computing enables multiple users to access and retrieve data simultaneously through their own personal Internet connections, which increases the risk of confidential data loss and exposure in a number of different places. Elliptic Curve Cryptography and other cryptographic algorithms have been used to develop numerous methods and protocols that guarantee the security and privacy of transmitted data. In this paper, we suggest a safe and efficient method for sharing information in the cloud without compromising its safety or integrity. The proposed system is able to guarantee authentication and data integrity because it uses a hybrid of the ECC and the Advanced Encryption Standard (AES) technique. The experimental results confirm the proposed approach outperforms the current gold standard. 相似文献

Cloud computing has become the buzzword in the industry today. Though, it is not an entirely new concept but in today's digital age, it has become ubiquitous due to the proliferation of Internet, broadband, mobile devices, better bandwidth and mobility requirements for end-users (be it consumers, SMEs or enterprises). In this paper, the focus is on the perceived inclination of micro and small businesses (SMEs or SMBs) toward cloud computing and the benefits reaped by them. This paper presents five factors influencing the cloud usage by this business community, whose needs and business requirements are very different from large enterprises. Firstly, ease of use and convenience is the biggest favorable factor followed by security and privacy and then comes the cost reduction. The fourth factor reliability is ignored as SMEs do not consider cloud as reliable. Lastly but not the least, SMEs do not want to use cloud for sharing and collaboration and prefer their old conventional methods for sharing and collaborating with their stakeholders. 相似文献

The emergence of sophisticated and powerful mobile devices with impressive computing capabilities and storage capacity paves the way for an era of advanced mobile-based applications. Monitoring of time-critical data, process control, and security are possible candidate applications. In this work we propose a stock monitoring system that utilizes mobile phones. The system was designed to provide an alternative to costly GPRS connections for stock market traders. The system grants real-time monitoring of stock information through a user-friendly and easy to use GUI with plenty of useful features. The system was implemented by combining various Java technologies, specifically J2ME and J2EE. It was tested using the Dubai Financial Market with favorable results. 相似文献

This study examines characteristics that relate to lead userness in using business mobile services. From a large dataset of 2306 business decision-makers, the study identifies 205 lead users who are ahead of the majority in using business mobile services, while for the majority (n = 2101), business mobile services mainly supplement desktop and laptop computers. The authors test a binary logistic regression model in which individual technology readiness, sociodemographic variables, Internet use, and perceived importance of digital touchpoints predict lead userness in relation to business mobile services. The results show that job level is a highly significant predictor for lead userness in a work-related context, with senior management and entrepreneurs having the greatest likelihood for the use of business mobile services. Innovativeness and the perceived importance of mobile applications and social media also serve as positive predictors, while the perceived importance of websites and email result in a negative effect. The findings further suggest that the odds of being a lead user decrease by 2 percent per additional year of age, and that the odds of men is over 1.4 times greater than the odds of women. 相似文献

Internet of things (IoT) coupled with mobile cloud computing has made a paradigm shift in the service sector. IoT-assisted mobile cloud based e-healthcare services are making giant strides and are likely to change the conventional ways of healthcare service delivery. Though numerous approaches for preventing unauthorized access to information exchanged between a mobile phone and cloud platform do exist, but there is no security mechanism to prevent unauthorized access by the cloud administrators. With an aim to ensure security of client data such as Electronic Patient Records (EPR), we propose a novel high-capacity and reversible data hiding approach for securely embedding EPR within the medical images using Optimal Pixel Repetition (OPR). OPR converts every pixel of the input image to a 2 × 2 block to facilitate reversibility by ensuring all the pixels in a 2 × 2 block to have different values. Since a 2 × 2 block is comprised of 4-pixel elements, which could be arranged in sixteen possible ways; we generate a lookup table corresponding to sixteen possible positions of pixels. EPR hiding in each block is achieved by permuting the pixels of a block according to the four-bit word of secret data, resulting in a histogram invariant stego image. The histogram invariance improves the robustness of the proposed scheme to statistical attacks. A stego image is said to hide embedded data securely, when it provides better imperceptivity for an appreciably high payload. Thus, while using information embedding approach for securing client data on a mobile-cloud platform, high imperceptivity is a desirable feature. Experimental results show that average PSNR obtained is 42 dB for payload 1.25 bpp by our scheme, showing its effectiveness for preventing unauthorized access to client’s sensitive data. 相似文献
