Semantic Privacy Policies for Service Description and Discovery in Service-Oriented Architecture

Privacy preservation in Service-Oriented Architecture (SOA) is an open problem. This paper focuses on the areas of service description and discovery. The problems in these areas are that currently it is not possible to describe how a service provider deals with information received from a service consumer as well as discover a service that satisfies the privacy preferences of a consumer. There is currently no framework which offers a solution that supports a rich description of privacy policies and their integration in the process of service discovery. Thus, the main goal of this paper is to propose a privacy preservation framework for the areas of service description and discovery in SOA. The framework enhances service description and discovery with the specification and intersection of privacy policies using a base and domain-specific privacy ontologies. Moreover, the framework extends SOA to include roles responsible for implementing a privacy registry as well as mediating the interactions between service consumers and providers and the privacy preservation component

Protecting Personal Private Information in Collaborative Environments

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 provides collaborating individuals with notice and choice surrounding their private information, in order to provide an individual with a level of control over how their information is to be used. To this end, a collaborative privacy architecture for providing privacy within a collaborative environment is presented. This architecture uses ontologies to express the static concept and relation definitions required for privacy and collaboration. The collaborative privacy architecture also contains a Collaborative Privacy Manager (CPM) service which handles changes in dynamic collaborative environments. The goals of this thesis are to provide privacy mechanisms for the non-client centric situation of collaborative working environments. This thesis also strives to provide privacy through technically enforceable and customizable privacy policies. To this end, individual collaborators are provided with access, modification rights, and transparency through the use of ontologies built into the architecture. Finally, individual collaborators are provided these privacy protections in a way that is easy to use and understand and use. A collaborative scenario as a test case is described to present how this architecture would benefit individuals and organizations when they are engaged in collaborative work. In this case study a university and hospital are engaged in collaborative research which involves the use of private information belonging to collaborators and patients from the hospital. This case study also highlights how different organizations can be under different sets of legislative guidelines and how these guidelines can be incorporated into the privacy architecture. Through this collaboration scenario an implementation of the collaborative privacy architecture is provided, along with results from semantic and privacy rule executions, and measurements of how actions carried out by the architecture perform under various conditions

An investigation of smartphone applications: Exploring usability aspects related to wireless personal area networks, context-awareness, and remote information access

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.In this thesis we look into usability in the context of smartphone applications. We selected three research areas to investigate, namely Wireless Personal Area Networks, Context-awareness, and Remote Information Access. These areas are investigated through a series of experiments, which focuses on important aspects of usability within software applications. Additionally, we mainly use smartphone devices in the experiments. In experiment 1, Multi-Platform Bluetooth Remote Control, we investigated Wireless Personal Area Networks. Specifically, we implemented a system consisting of two clients, which were created for Java ME and Windows Mobile, and integrated with a server application installed on a Bluetooth-enabled laptop. For experiments 2 and 3, Context-aware Meeting Room and PainDroid: an Android Application for Pain Management, we looked closely at the research area of Contextawareness. The Context-aware Meeting Room was created to automatically send meeting participants useful meeting notes during presentations. In experiment 3, we investigated the use of on-device sensors for the Android platform, providing an additional input mechanism for a pain management application, where the accelerometer and magnetometer were used. Finally, the last research area we investigated was Remote Information Access, where we conducted experiment 4, Customised Android Home Screen. We created a system that integrated both a cloud-based server application and a mobile client running on the Android platform. We used the cloud-computing platform to provide context management features, such as the ability to store the user configuration that was automatically pushed to the mobile devices
