The research and development project SAFER INTERNET aims at providing a technical solution for a more protected use of the Internet for families, schools, and Internet users in general. The main goal is to tackle harmful and objectionable content such as pornography, violence or racism based on individual user preferences and without imposing forced censorship on users.

The Safer Internet Project is a joint binational project between SES ASTRA, Luxembourg; the Hasso Plattner Institute at the University of Potsdam, Germany; and the University of Luxembourg & LIASIT.

About HPI
The HPI in Potsdam is the only university-level institute in Germany offering study programs in IT-Systems Engineering. The HPI has no tuition fees and is financed entirely through private funds donated by its founder, Professor Hasso Plattner, who co-founded the software giant SAP and is currently its chairman of supervisory board. Plattner is the most important private supporter of science in Germany and will contribute a total of more than 200 million euro to further promote this unique university-level training in IT Systems Engineering.

More information about the HPI is available at www.hpi-web.de.

About SES ASTRA
SES ASTRA is the leading Direct-to-Home (DTH) satellite system in Europe. The satellite fleet currently comprises 14 ASTRA and two SIRIUS satellites. The combined satellite system delivers services to more than 122 million DTH and cable households and transmits nearly 2,500 analogue and digital television and radio channels. SES ASTRA also provides satellite-based multimedia, internet and telecommunication services to enterprises, governments and their agencies. With nearly 70 High Definition (HD) channels on its main orbital positions, ASTRA and SIRIUS represent the most important HDTV platform for Europe's leading broadcasters.
