Cloud computing services has gained increasing popularity in recent years for supporting various on demand and scalable services for IT consumers where there is a need of less investment towards infrastructure. While storage architecture of cloud enjoys a more robust and fault-tolerant cloud computing network, such architecture also poses a number of security challenges especially when applied in applications related to social networks, Financial transactions, etc. First, as data are stored and maintained by individual virtual machines so Cloud resources are prone to hijacked. Such attacks allow attackers to create, modify and delete machine images, and change administrative passwords and settings successfully. hence, it is significantly harder to ensure data security. Second, Due to dynamic and shared nature of the Cloud, data may be compromised in many ways. Last but not least, Service hijacking may lead to redirect client to an illegitimate website. User accounts and service instances could in turn make a new base for attackers. To address the above challenges, we propose in this paper a distributed data access control scheme that is able to fulfil fine-grained access control over cloud data and is resilient against strong attacks such as compromise and user colluding. The proposed framework exploits a novel cryptographic primitive called attribute-based encryption (ABE), tailors, and adapts it for cloud computing with respect to security requirements

In recent years, electronic commerce has provided another access for consumers to purchase products. Shopping on line provides much information and less searching cost for customers, but some researches have pointed out that there are difficulties for companies to do business on web. For lack of trust, many people not prefer purchasing through virtual channels. Based on the literature review, this study aims at empirically testing the impact of website design on individual trust in internet firms. From statistic analysis, we will conclude that security, interaction, and navigation functionality will affect on-line trust. The result of this study may provide some managerial implications, especially for firms which want to enter on-line businesses.

One of the most discussed topics is cyber security when it comes to web application and how to protect it and protect databases. One of the most widely used and widespread techniques is SQLI, and it is used by hackers and hackers. In this research, we touched on the concept of SQLI and what are its different types, and then we detected a SQLI vulnerability in a website using SQLMAP. Finally, we mentioned different ways to avoid and protect against SQLI.

A resident registration number is used to confirm and prove his/her identity in a government/non-governmental agency. It is a essential requirement to become the registered member on internet website in Korea. It is serious problem that the resident registration number and name are outflowed in internet and misused by others. So the MIC(Ministry of Information and Communication) in Korea plans and operates the identification system using I-PIN that integrate 5 alternative methods of resident registration number. In this paper, we analyze the problem about the method of 5 I-PIN services and show the security analysis on the implementation vulnerabilities of I-PIN services. we also analyze 17 websites that provides identification system using I-PIN. Finally, we analyze the overall problem of I-PIN service and propose the countermeasure about the problem.

본 논문에서는 전기차 시장의 성장 및 수요 증가로 인한 충전 인프라 부족에 대한 문제를 해소하기 위한 방안으로, 센서를 활용한 각 자리별 빈 주차 자리 확인 기능과 전기차 충전 자리의 남은 대기 시간에 대한 정보를 실시간 모니터링 할 수 있는 시스템을 구현하였다. 기존의 LED 표시등의 정보를 웹사이트를 통해 시각적으로 전달하며, 실시간으로 주차 여유 공간과 전기차 충전 자리의 대기 시간을 확인할 수 있게 하였다. 더불어 발레 파킹 서비스와의 융합을 통해 충전 완료 후 차량 이동의 불편함 및 인프라 운영의 효율을 늘리는 방안을 제안해본다.

Since the general quality of life has been improving, people have become interested in "well-being." The widespread acceptance of the importance of "well-being" to quality of life has encouraged people to take more interest in getting health information online when they need it. Expansive use of online health information suggests that individual characteristics (i.e., gender and other traits), Website features, and perceived trust are related to the primary concern for many online health information consumers. This study examines whether familiarity, perceived security, and reputation of health information on various Websites influence the relationship of trust and intention to use by gender. These research results will contribute to the adoption of online health information by gender and, moreover, will provide companies with an understanding of key characteristics of consumers who use emoticons and provide useful implications for marketing strategies to current and future consumers.

Education is one of the pillars of sustainable development. For this reason, the discovery of useful information in its process of adaptation to new challenges is treated with care. This paper aims to present the initiation of a process of exploring the data collected from the results obtained by Romanian students at the BBaccalaureate (the Romanian high school graduation) exam, through data mining methods, in order to try an in-depth analysis to find and remedy some of the causes that lead to unsatisfactory results. Specifically, a set of public data was collected from the website of the Ministry of Education, on which several classification methods were tested in order to find the most efficient modeling algorithm. It is the first time that this type of data is subjected to such interests.

Email phishing has become very prevalent especially now that most of our dealings have become technical. The victim receives a message that looks as if it was sent from a known party and the attack is carried out through a fake cookie that includes a phishing program or through links connected to fake websites, in both cases the goal is to install malicious software on the user's device or direct him to a fake website. Today it is difficult to deploy robust cybersecurity solutions without relying heavily on machine learning algorithms. This research seeks to detect phishing emails using high-accuracy machine learning techniques. using the WEKA tool with data preprocessing we create a proposed methodology to detect emails phishing. outperformed random forest algorithm on Naïve Bayes algorithms by accuracy of 99.03 %.
