Termin:Chaotic-Congress-Cinema Nr. 6

Needs to be there, but does not need to be seen by a visitor Yes Wir schauen uns die Aufzeichnung von Congress Vorträgen an. Du bist herzlich eingeladen, in den Clubräumen im Mexikoring 21 aufzutauchen und mit uns die Talks anzuschauen und zu diskutieren. Es wird Getränke und Knabberkram zu moderaten Preisen geben. Falls Du kein CCC-, CCCHH- oder Attraktor e.V.-Mitglied bist, macht das überhaupt nichts: Alle Gäste sind gern gesehen. :-)

Terrorists Win - Exploiting Telecommunications Data Retention?

Telecommunications data retention (TDR) has become a reality in most Western countries. Protagonists claim that the collection of massive amounts of data on the communication behavior of all individuals within a country would enable law enforcement agencies to exploit patterns in the stored data to uncover connections between suspects.

While this is obviously true for investigations after an incident happened, there is up to now no critical and sound assessment publicly available that evaluates whether TDR brings any pro-active benefits for the above mentioned, justified purposes.

In this talk we give for the first time a critical assessment of the power of TDR based on methods from information theory. To this end we have employed agent based simulations, which mimic the communication behavior of a large community including a dark-net of alleged suspects. The structure and statistics of our telecommunication simulation, which drive the dynamics of telephone calls and simulated TDR data, were generated according to known statistics of real-world telecommunications networks.

Hiding in the unavoidable noise seems to be a passive strategy for terrorists to circumvent pro-active detection. This stems from a "needle in the haystack"-problem, that arises due to the small number of conspirators compared to the number of other participants.

In particular situations and with adopted strategies suspected terrorists might be able to eventually exploit TDR for their purposes and take an active approach to hiding in the crowd. Such TDR exploits would lower the probability of detection by law enforcement agencies and render TDR a potential security threat. Again, we use our simulations and our analysis procedure to assess this problem.

Adventures in Mapping Afghanistan Elections

The story of 3 Ushahidi mapping and reporting projects.

Monitoring and reporting about elections in a war zone is a complex and dangerous task. While crisis mapping carried out via sms and email proved highly successful with the use of Ushahidi in situations like post-election violence in Kenya, tracking crime in Atlanta, or earthquake recovery in Haiti, could it prove useful in such a complex situation as the Afghan political process? This year a team of people set out to do just that with three different Ushahidi mapping projects for national media, national election observers, and international observers. The following presentation is about the challenges we faced, successes we did or did not have, and the lessons learned for the future of crisis mapping.

In 2008 an open source mapping system called Ushahidi was put into public use for the first time in history. The occasion was a constitutional referendum in Kenya and the goal of the Ushahidi system was to map and track reports of violence throughout the country in the days following the vote. Through the use of sms reports from the general public, which were then categorized and published on an interactive map accessible on the internet, anyone anywhere in the world could not only get reports about what was happening, they could get almost real time reports about where violence was happening, when, and details regarding those incidents.

The response in Kenya was so large and the attention the site got was so wide spread, Ushahidi would soon be used to map not only violence surrounding an election, but also earthquake recovery, snow storm recovery, forest fire prevention, crime data in urban environments, and elections monitoring. In each of these situations, the power of crowd-sourcing and interactive mapping via simple sms and email technology was all that was needed to get a body of information no media or government organization could compete with.

In the summer of 2010, on the eve of Parliamentary elections in Afghanistan, several organizations interested in monitoring what happens at the polls and after the votes are in became interested in whether or not Ushahidi could be useful for their purposes. The Afghan Press agency, Pajwhok, as well as the national elections observer organization (FEFA) and the international elections observers (Democracy International) all sought to implement some form of Ushahidi system for their observers. They approached my organization, Small World News (SWN) that has assisted in Ushahidi projects in the past, to carry out this task.

Over the course of just over 1 month, these three systems were rolled out in different ways, with varying level of restrictions due to security and other institutional regulations. The result tells three different stories about how the election went, while also providing a list of lessons about what open source interactive mapping can provide (or not provide) for a nation like Afghanistan with such a specific list of problems.

The presentation is an explanation of both the process and the lessons learned.
