Qualifying Location Privacy
With the term paper about k-Anonymity I already covered some method to quantify privacy in relational databases and pointed out that it becomes much harder to protect privacy with all the collection of data nowadays.Read itSlides
This term paper addresses how you can quantify privacy regarding your location. Since almost everyone has a smartphone and location aware apps are everywhere (e.g. Facebook Places or Google Latitude) location privacy becomes more and more important.
k-Anonymity and its influence on later research
While doing research for my bachelor thesis I already stumbled over Sweeney’s “k-Anonymity”-paper. When I got the chance to dig further into this topic by participating in a seminar I seized the opportunity to do so. The best part is that I not only could engage in the whole “how to retain privacy”-discussion but also that I got an general overview why sometimes anonymous data is not as anonymous as you might think.Read itSlides
Re-identification is too easy, because a lot of the available information about a person is not considered personally identifiable information and is therefore not protected. But actually almost everything can help to identify a person.
Bachelor Thesis: Codename Hinky
To solve this problem I developed a Firefox add-on that lets you use the front end and prevents the database service from reading your data. The add-on prototype can be found in the “Software” section.
XML Encryption & CLV as a Web Service
This paper was part of a interdisciplinary seminar. Studentds from the field of economics and computer science attempt to find a solution for a dynamic price system, which incorporates statistical and background data from customers. My part was to implement the customer lifetime value (CLV). In our scenario this value was used as an estimated net present value. Meaning how much is the customer worth in Euro.Read itSlides
SWAT – Petri net editor & analysis framework
SWAT is a editor build on Eclipse RPC and GEF (which are both awesome frameworks btw). For now it is a very basic editor with the typical add, remove, move, etc. plus an interface to plug in your analysis algorithm. The latter was the main reason to build another Petri net editor. Since this project was part of my master program I alsmost stopped working on SWAT. But there will hopefully be some further courses, which will enhance SWAT.
Customer Value Evaluation (CuVE)
WordPress Plugin: WP MtG Helper
I started this project in Summer 2008 because I couldn’t find a suitable method to link cards from Magic: the Gathering. Even most of the websites, which featured this game, used pop ups and similiar methods to display cards. You always had to click a link, if you wanted to see the card. I thought it would be neat if a mouseover would suffice. So I started to tinker around and learn to build an WordPress plugin. Over time I also added an easy way to display decklists and draft picks.DownloadGo toDemo
The plugin is still used with and without modifications (see picture below). I hope that this will not change so soon.
