In this paper, we consider a model of lossless image compression in which each band of a
multispectral image is coded using a prediction function involving values from a previously …

Policy-based access control systems are crucial for secure information sharing in
collaborative applications. However, policy management needs to be flexible in order to …

Over the past few years, hybrid storage architectures that use high-performance SSDs in
concert with high-density HDDs have received significant interest from both industry and …

Managing large systems in order to guarantee certain behavior is a difficult problem due to
their dynamic behavior and complex interactions. Policies have been shown to provide a …

Sensitive data is available online through web and distributed protocols that highlight the
need for access control mechanisms. System designers write access control policies to …

The purpose of autonomic networking is to manage the business and technical complexity of
networked components and systems. However, the lack of a common lingua franca makes it …

A key part of the policy authoring process is analysis of the potential for newly created or

In recent years, XACML (eXtensible Access Control Markup Language) has been widely
used in the development of various applications, especially Web services. The evaluation …

We present a policy conflict analysis process that makes use of pre-defined semantic
models of an application to perform effective and efficient conflict analysis. The process is …
