The Application of Fuzzy Logic Controller to Compute a Trust Level for Mobile Agents in a Smart Home
Agents that travel through many hosts may cause a threat on the security of the visited hosts. Assets,
system resources, and the reputation of the host are few possible targets for such an attack. The
possibility for multi-hop agents to be malicious is higher compared to the one-hop or two-hop
boomerang agents. The travel history is one of the factors that may allow a server to evaluate the
trustworthiness of an agent. This paper proposes a technique to define levels of trust for multi-hop
agents that are roaming in a smart home environment. These levels of trust are used later to
determine actions taken by a host at the arrival of an agent. This technique uses fuzzy logic as a
method to calculate levels of trust and to define protective actions in regard to those levels
Privacy Issues of the W3C Geolocation API
The W3C's Geolocation API may rapidly standardize the transmission of
location information on the Web, but, in dealing with such sensitive
information, it also raises serious privacy concerns. We analyze the manner and
extent to which the current W3C Geolocation API provides mechanisms to support
privacy. We propose a privacy framework for the consideration of location
information and use it to evaluate the W3C Geolocation API, both the
specification and its use in the wild, and recommend some modifications to the
API as a result of our analysis
Management system requirements for wireless systems beyond 3G
This paper presents a comprehensive description of various management system requirements for systems beyond 3G, which have been identified as a result of the Software Based Systems activities within the Mobile VCE Core 2 program. Specific requirements for systems beyond 3G are discussed and potential technologies to address them proposed. The analysis has been carried out from network, service and security viewpoints
A qualitative study of stakeholders' perspectives on the social network service environment
Over two billion people are using the Internet at present, assisted by the mediating activities of software agents which deal with the diversity and complexity of information. There are, however, ethical issues due to the monitoring-and-surveillance, data mining and autonomous nature of software agents. Considering the context, this study aims to comprehend stakeholders' perspectives on the social network service environment in order to identify the main considerations for the design of software agents in social network services in the near future. Twenty-one stakeholders, belonging to three key stakeholder groups, were recruited using a purposive sampling strategy for unstandardised semi-structured e-mail interviews. The interview data were analysed using a qualitative content analysis method. It was possible to identify three main considerations for the design of software agents in social network services, which were classified into the following categories: comprehensive understanding of users' perception of privacy, user type recognition algorithms for software agent development and existing software agents enhancement
Privacy in crowdsourcing:a systematic review
The advent of crowdsourcing has brought with it multiple privacy challenges. For example, essential monitoring activities, while necessary and unavoidable, also potentially compromise contributor privacy. We conducted an extensive literature review of the research related to the privacy aspects of crowdsourcing. Our investigation revealed interesting gender differences and also differences in terms of individual perceptions. We conclude by suggesting a number of future research directions.</p
Protecting mobile money customer funds in civil law jurisdictions
The provision of financial services through mobile phones is a powerful tool to foster financial inclusion, and thus economic growth, in developing countries. However, it raises important regulatory issues. Given the vulnerability of most potential customers of these services, the protection of customer funds is important. In common law countries, trust accounts are an effective response to these concerns. In civil law jurisdictions however, in the absence of trusts, protection of customer funds is more difficult. This paper identifies the theoretical and practical problems that regulators in civil law jurisdictions might face when trying to protect customer funds and explores how fiduciary contracts, mandate contracts and direct regulation might be used to achieve this goal. It offers a series of practical recommendations for policymakers in developing countries that provide a range of regulatory options that combine private law and regulation
