Security Issues In Data Warehouse, Saiqa Aleem, Luiz Fernando Capretz, Faheem Ahmed Dr.

Electrical and Computer Engineering Publications

Data Warehouse (DWH) provides storage for huge amounts of historical data from heterogeneous operational sources in the form of multidimensional views, thus supplying sensitive and useful information which help decision-makers to improve the organization’s business processes. A data warehouse environment must ensure that data collected and stored in one big repository are not vulnerable. A review of security approaches specifically for data warehouse environment and issues concerning each type of security approach have been provided in this paper.

Extending The Sensing Of Online Social Networks – A Healthcare Perspective, Asma’ Wasfi Fayez Mustafa

Theses

Obesity is a rising health concern in the United Arab Emirates. Obesity leads to health risks such as diabetes, heart disease, and other conditions. It may also lead to eating disorders, depression, and low self-esteem. Regular exercising helps to protect from obesity, diabetes, heart disease, high blood pressure and better manage stress. Despite all the benefits of exercising, people are doing less of it. In this research, an effort is made to encourage people to exercise by extending the prevalent sensing abilities of Online Social Networks (OSNs). Sensors are used to collect and generate data to be processed, clustered and …

Protecting Personal Private Information In Collaborative Environments, David S. Allison

Electronic Thesis and Dissertation Repository

The ability to collaborate has always been vitally important to businesses and enterprises. With the availability of current networking and computing power, the creation of Collaborative Working Environments (CWEs) has allowed for this process to occur anytime over any geographical distance. Sharing information between individuals through collaborative environments creates new challenges in privacy protection for organizations and the members of organizations. This thesis confronts the problems when attempting to protect the personal private information of collaborating individuals.

In this thesis, a privacy-by-policy approach is taken to addressing the issue of protecting private information within collaborative environments. A privacy-by-policy approach to …

Privacy Protection Framework With Defined Policies For Service-Oriented Architecture, David Allison, Miriam Capretz, Hany Elyamany, Shuying Wang

David S Allison

Service-Oriented Architecture (SOA) is a computer systems design concept which aims to achieve reusability and integration in a distributed environment through the use of autonomous, loosely coupled, interoperable abstractions known as services. In order to interoperate, communication between services is very important due to their autonomous nature. This communication provides services with their functional strengths, but also creates the opportunity for the loss of privacy. In this paper, a Privacy Protection Framework for Service-Oriented Architecture (PPFSOA) is described. In this framework, a Privacy Service (PS) is used in combination with privacy policies to create privacy contracts that outline what can …

Evidentiary Power And Propriety Of Digital Identifiers And The Impact On Privacy Rights In The United States, Michael Losavio, Deborah Keeling

Journal of Digital Forensics, Security and Law

Media and network systems capture and store data about electronic activity in new, sometimes unprecedented ways; computational systems make for new means of analysis and knowledge development. These new forms offer new, powerful tactical tools for investigations of electronic malfeasance under traditional legal regulation of state power, particular that of Fourth Amendment limitations on police searches and seizures under the U.S. Constitution. But autonomy, identity and authenticity concerns with electronic data raise issues of public policy, privacy and proper police oversight of civil society. We examine those issues and their implications for digital and computational forensics

Effects Of The Factory Reset On Mobile Devices, Riqui Schwamm, Neil C. Rowe

Journal of Digital Forensics, Security and Law

Mobile devices usually provide a “factory-reset” tool to erase user-specific data from the main secondary storage. 9 Apple iPhones, 10 Android devices, and 2 BlackBerry devices were tested in the first systematic evaluation of the effectiveness of factory resets. Tests used the Cellebrite UME-36 Pro with the UFED Physical Analyzer, the Bulk Extractor open-source tool, and our own programs for extracting metadata, classifying file paths, and comparing them between images. Two phones were subjected to more detailed analysis. Results showed that many kinds of data were removed by the resets, but much user-specific configuration data was left. Android devices did …

Efficient Anonymous Biometric Matching In Privacy-Aware Environments, Ying Luo

Theses and Dissertations--Electrical and Computer Engineering

Video surveillance is an important tool used in security and environmental monitoring, however, the widespread deployment of surveillance cameras has raised serious privacy concerns. Many privacy-enhancing schemes have been recently proposed to automatically redact images of selected individuals in the surveillance video for protection. To identify these individuals for protection, the most reliable approach is to use biometric signals as they are immutable and highly discriminative. If misused, these characteristics of biometrics can seriously defeat the goal of privacy protection. In this dissertation, an Anonymous Biometric Access Control (ABAC) procedure is proposed based on biometric signals for privacy-aware video surveillance. …
