This article proposes a new technique for Privacy Preserving Collaborative Filtering (PPCF) based on microaggregation, which provides accurate recommendations estimated from perturbed data whilst guaranteeing user k-anonymity. ...

Java is increasingly used to develop large server applications. In order to provide powerful platforms for such applications a number of projects have proposed Java Virtual Machines (JVMs) that are based on network ...

Many Internet security mechanisms depend on the use of cryptographic algorithms for various forms of authentication and confidentiality. Even when well-known and standardized cryptographic algorithms are used in well-known ...

The complexity of current computing networks and the required fluidity of their operation requires autonomy to be central to the design and implementation of a managed overlay network. This paper presents a system in which ...

Earth tremors are a constant, intrinsic part of our planet's nature and a visceral experience when first encountered. Kosmoscope, a telematic art installation by Tim Redfern, marries two venerable technologies, the ...

In recent years, there has been an increase in the popularity of Light Field (LF) imaging technology with the increase in availability of LF camera devices such as the Lytro, as well as an increase in the use of LF ...

As ubiquitous computer and sensor systems become abundant, the potential for automatic identification and tracking of human behaviours becomes all the more evident. Annotating complex human behaviour datasets to achieve ...

The field of information retrieval still strives to develop models which allow semantic information to be integrated in the ranking process to improve performance in comparison to standard bag- of-words based models. ...

Computer users, especially mobile ones, have developed a significant dependency on electronic communication. Enhancing the capabilities of such communication by adding an awareness of context such as location and ...
