Todays Web Applications are complex distributed applications, that deploy their functionality to the World Wide Web. In many cases Web Applications have been developed by using an adhoc and unsystematic development process. As a conesquence these applications have a high probability of failure during operation. In order to develop high quality Web Application both the development process and th...

Up to now Service Oriented Architectures and Event Driven Architectures have been considered as competing parties striving to conquer the crown of the standard paradigm for the implementation of complex distributed applications. Todays we are witnesses of large efforts to merge both paradigms and give birth to a new generation of middleware platforms that will inherit the best of both worlds. I...

The Internet has become the common medium for content distribution. Searching content using keywords is well-known. But there are many shortcomings to it. Users cannot search within the content and on many of the attributes of the content, i.e., other than its name. Content is also becoming increasingly decentralized. New mechanisms allowing access to complex distributed content is needed. We i...

We have seen that additive noise technique is not (SV (γ), ε)-DP. So, the question that we explore in todays class is whether differential privacy (DP) is achievable with SV sources. Interestingly, we give a differential private mechanism for approximate arbitrary “low sensitive” functions that works even with randomness coming from SV source, for any γ < 1. We conclude todays lecture with some...
