To create solutions for providing the required access control in computer networks it is not sufficient to have only tools and protocols in the network that are needed for it. It is necessary to create corresponding configuration, or scheme, of such ...

Multi-agent planning using MA-STRIPS–related models is often motivated by the preservation of private information. Such a motivation is not only natural for multi-agent systems but also is one of the main reasons multi-agent planning problems cannot be ...

We exploit Decision Networks (DN) for the analysis of attack/defense scenarios in critical infrastructures. DN extend Bayesian Networks (BN) with decision and value nodes. DN inherit from BN the possibility to naturally address uncertainty at every ...

A “noisy-rich” (NR) cyber-attacker (Lippmann et al. 2012) is one who tries all available vulnerabilities until he or she successfully compromises the targeted network. We develop an adversarial foundation, based on Stackelberg games, for how NR-...

We address the problem of associating access policies with datasets and how to monitor compliance via policy-carrying data. Our contributions are a formal model in first-order logic inspired by normative multi-agent systems to regulate data access, and ...

Point-of-Interest (POI) recommendation is a new type of recommendation task that comes along with the prevalence of location-based social networks and services in recent years. Compared with traditional recommendation tasks, POI recommendation focuses ...

The past few years have seen an explosion in the popularity of online short-video sharing in YouTube. As the number of users continue to grow, the bandwidth required to maintain acceptable quality of service (QoS) has greatly increased. Peer-to-peer (...

This article aims to develop a method to detect visual differences introduced into web pages when they are rendered in different browsers. To achieve this goal, we propose an empirical visual similarity metric by mimicking human mechanisms of ...

Knowledge Bases (KBs) are widely used as one of the fundamental components in Semantic Web applications as they provide facts and relationships that can be automatically understood by machines. Curated knowledge bases usually use Resource Description ...

IP (Internet Protocol) version 6 (IPv6) was standardised in 1998 to address the expected runout of IP version 4 (IPv4) addresses. However, the transition from IPv4 to IPv6 has been very slow in many countries. We investigate the state of IPv6 deployment ...

Community-based Question Answering (CQA) websites are attracting increasing numbers of users and contributors in recent years. However, duplicate questions frequently occur in CQA websites and are currently manually identified by the moderators. ...

Geographically distributed cloud platforms are well suited for serving a geographically diverse user base. However, traditional cloud provisioning mechanisms that make local scaling decisions are not adequate for delivering the best possible performance ...

With the increasing popularity and rapid development of Online Social Networks (OSNs), OSNs not only bring fundamental changes to information and communication technologies, but also make an extensive and profound impact on all aspects of our social ...
