Hello, Bonjour, Guten Tag,



I have set up this site in order to keep contact with my friends back in 2005


However, in the meantime social media technologies have been proven more effective than web pages to keep in contact.


So, you will find me also on Xing or LinkedIn:




Moreover, I am about to continue my academic career. You can follow the progress of my PhD over here …. 




or have a look at my diploma work from 2005, if you like http://www.daniel-hallen.com/Docs/Handset_Security_Offer_Complete.pdf



Best regards,



Daniel Hallen
