As part of the National Cyber Strategy, the government is working to ensure connected places technology is adopted in a secure and sustainable way. To support this work, Department for Science, Innovation and Technology (DSIT) commissioned PETRAS to conduct a literature review. The focus of this review was to explore how public perceptions of conn...

• Individual privacy expectations and preferences are highly contextualised and shaped by individual, social, and cultural expectations and norms. • Contexts are useful to decide whether it is appropriate for an individual to share information. • To this extent, we modelled the role of contexts in privacy decisions

People are interacting with online systems all the time. In order to use the services being provided, they give consent for their data to be collected. This approach requires too much human effort and is impractical for systems like Internet-of-Things (IoT) where human-device interactions can be large. Ideally, privacy assistants can help humans ma...

User privacy preferences are diverse and context dependent. Contexts are useful to decide if it is appropriate for an individual to share information. To this extent, we would like to understand the role of contexts in privacy decisions better.

Algorithmic systems are increasingly deployed to make decisions that people used to make. Perceptions of these systems can significantly influence their adoption, yet, broadly speaking, users understanding of the internal working of these systems is limited. To explore users perceptions of algorithmic systems, we developed a prototype e-recruitment...

The scale, heterogeneity, pervasiveness and dynamism of Internet of Things (IoT) environments introduce some privacy issues for the users and those who are affected by the environments. This is because IoT systems rely heavily on collecting data; and the major areas of concerns include the potential impact of such information flow on the privacy of...

The conclusions drawn from a dialogue depend both on the content of the arguments, and the level of trust placed in the arguments and the entity advancing them. In this paper, we describe a framework for dialogue where such trust forms the basis for expressing preferences between arguments, and in turn, for computing conclusions of the dialogue. Ou...

We present an argumentation framework for reasoning within deliberation dialogues. This framework includes a dynamic notion of trust — the degree of belief placed in the dialogue participants changes over the course of the dialogue, and in turn affects the strength of the arguments the participants advance , affecting the dialogue's conclusions.

This paper presents multifactor authentication method for securing access to e-banking systems in Nigeria using fingerprint recognition and SiteKey authentication. Fingerprint authentication is based on the notion of fingerprint individuality; the idea that fingerprint image of an individual is unique and can be used to uniquely identify him/her. S...

The recently introduced cashless economy with the cash-lite banking by the Central Bank of Nigeria (CBN) has engineered most Nigeria banks to introduce e-payment and e-transact solutions to support the policy. However, one of the major problems limiting the growth of this new move in Nigeria is the absence of secure and reliable e-payment systems....
