This research proposes a solution to enhance the security of VoIP...
Traditionally, programmer learns to write code using arrays and loops to perform complex computation. Languages designed specifically for scientific computation such as Matlab/Octave support vector based operations which are much faster than arrays and loops. However, converting the loop oriented code to a vector based operation requires skilled programmer, takes time, and introduces many errors....
Online Social Network (OSN), such as Face book, Linked In, Twitter, is today's one of the most popular platform on the internet where millions of users sign on daily to share personal information with friends and colleagues.

The problem of removing sensitive information from data before it is released publicly, or turned over to less trusted analysts, underlies much of the unwillingness to share data. The solution is to sanitize, or deidentify, parts of the data. When dealing with network addresses, the set of available addresses is finite. This limits some aspects of the sanitization. We analyze this problem in detail,...
