ITGumbo: spicing IT up

Data is the building block of the semantic web; therefore security of all data in the semantic web is the essential requirement for the success of semantic web. The web service provider and web service requester data must be secured. Web services specifications and semantic technologies provide mechanisms to define and execute security policies for different types of data. Data that must be secured is:

• Published data - Data that has been published by the web service provider as HTML web content or is accessible according to Message Exchange Pattern (MEP) described in Web Service Definition (WSD) document.

• Concealed data - Data that is stored in the internal storage media of the web service provider and is not available for public access. Data that is stored in the personal computer storage media of the web user who connects to the semantic web.

• Personal Identifiable Information - Data that is provided by the web service requester and is collected by the web service provider.
