With the increase in interest in web based e-commerce, the amount of business that is transacted on-line and the explosion in the amount of services available, the ability to
handle security and privacy is a must. Also, as computationally enabled devices (laptops, phones, PDAs, and even household appliances) become more commonplace and short range wireless connectivity improves; there...]]></description>

Acting as a record-keeper, this agent tracks a user's context by acquiring information from external sources (e.g., the context brokers in different smart spaces). Acting as an information provider, this agent shares the updated context information about a user with systems that attempt to provide services to the user.

  <description><![CDATA[Security is a critical problem in dynamic and open distributed
environments such as those enabled by the semantic web and pervasive computing technologies. The presence of heterogeneous entities that
are neither pre-determined nor permanent, and the lack of central
control are some of its challenges.  We believe that declarative
policies address this problem while maintaining openness and
flexibility.  We propose the use of policies defined in OWL to

  <description><![CDATA[Current access control research follows two parallel themes: many efforts focus on developing novel access control models meeting the policy needs of real world application domains while others are exploring new policy languages. This paper is motivated by the desire to develop a synergy between these themes facilitated by OWL. Our vision for the future is a world where advanced access control concepts are embodied in models that are supported by policy languages in a natural intuitive manner...]]></description>

  <description><![CDATA[Specialized stores for RDF data are essential parts of many
Semantic Web applications. Current RDF stores have primarily
focused on efficiently storing and querying large volumes
of data and little attention has been given other features
common to many database systems, including how information
can updated and maintained or access to data
controlled. The problem is complicated by the fact that the

The presence of website published P3P policies enable users to configure web browsers to

The presence of P3P policies enable users to configure web browsers to constrain what they can and cannot do when visiting websites.  It's a good idea that unfortunately is rarely used.  We identify two reasons: (i) the languages available to define a user's privacy preferences are not very expressive and (ii) most websites do not have published P3P policies.

These physical methods use system-based controls to verify the identity of a person or process, explicitly enabling or restricting the ability to use, change, or view a computer resource. However, these strategies are inadequate for the increased flexibility that distributed networks such as the Internet and pervasive computing environments require because such systems l...]]></description>
