Digital forensic investigators experience a need for support in their everyday struggle to overcome boundary problems associated with cyber crime investigations. Traditional methods are socio-culturally and physically localised and dependent on strict and historically prescriptive political management. The new internet-worked cyber-world creates unprecedented difficulties for digital forensic i...

Online spaces that enable public shared inter-personal communications are of significant social and economic importance. This paper outlines a theoretical model and methodology, labeled cyber-archaeology, for researching the relationship between such spaces and the behaviors they contain. The methodology utilizes large-scale field studies into user behavior in online spaces to identify technolo...

One method of privacy-preserving accounting or billing in cyber-physical systems, such as electronic toll collection or public transportation ticketing, is to have the user present an encrypted record of transactions and perform the accounting or billing computation securely on them. Honesty of the user is ensured by spot checking the record for some selected surveyed transactions. But how much...

this study draws attention to the ubiquitous and borderless nature of cybercrime. it examines the prospect of introducing customized cyber insurance policy in the nigerian market. as secondary data was not available, the study conducted a survey by administering three sets of questionnaire to purposively selected top executives in four trade groups that rely heavily on internet transactions for...

Kalman filtering has been widely considered for dynamic state estimation in smart grids. Despite its unique merits, the Kalman Filter (KF)-based dynamic state estimation can be undesirably influenced by cyber adversarial attacks that can potentially be launched against the communication links in the Cyber-Physical System (CPS). To enhance the security of KF-based state estimation, in this paper...

The fifteen papers in this special section focus on computing and networking for cyber-physical systems (CPSS). world we are living is rapidly evolving into a hybrid integrated designed within cyber, physical, social spaces also referred to as Cyber-Physical- Social Systems. CPSS, an emerging paradigm, will provide efficient, convenient, personalized services humans. Data records of users’ traj...

Requirements engineering has been mainly focused on software development, which represents relatively homogenous, stable and predictable cyber space. But even there, problems in requirements (e.g., changing, missing or irrelevant requirements) are considered as main reasons for project failure. Entering a new era of socio-cyber-physical systems, which are complex, heterogeneous systems of syste...

This work establishes a cyber space of an urban area for visiting on the Internet. By registering entire scenes along every street and scenes at many locations, people can visually travel from street to street, and reach their destinations in cyber city. The issues we discuss here are how to map a large scale area to image domain in a small amount of data, how to cover visual information as com...
