XACML is an OASIS standard that describes both a policy language and an access control decision request/response language (both encoded in XML). The policy language is used to describe general access control requirements, and has standard extension points for defining new functions, data types, combining logic, etc. The request/response language lets you form a query to ask whether or not a given action should be allowed, and interpret the result. The response always includes an answer about whether the request should be allowed using one of four values: Permit, Deny, Indeterminate (an error occurred or some required value was missing, so a decision cannot be made) or Not Applicable (the request can't be answered by this service).

I have written two tutorials which can be used by beginners to quickly learn and start using XACML. The tutorial employs the use of a case which eases in the learning of XACML.

Privacy and Protection of User Data is of utmost importance in todays digital age when organizations are collecting large amounts of user data.

We implemented the concept of Limited Disclosure of Data based on Hippocratic Databases as described by Rakesh Aggarwal et Al.

I ve mentioned some interesting reads in the Useful Links section.

WIKI : An artificial neural network (ANN) [Wiki] or commonly just neural network (NN) is an interconnected group of artificial neurons that uses a mathematical model or computational model for information processing based on a connectionist approach to computation. In most cases an ANN is an adaptive system that changes its structure based on external or internal information that flows through the network.

For me : They are things that can be taught almost anything. Things that use and apply their experience.

The human brain is one complex thing. Learning about the way humans think and learn is fascinating to say the least. I studied a little about ANN and used them for very elementary character recognition.

I have written a C++ program that can be used to teach the Neural Network characters by first inputting them into a Matrix and then testing the results. There is a lot of scope for improvement in this program. Your feedback would be very valuable.

p.s. : I referred to papers on the topic, you can find the references in the Links Section.

I am quite proud of the fact that I created this site design right from scratch and in the most modular manner possible. If you like the template then please feel free to use it. A little credit for the work would be great :).
