Linked Data Based Crime Analysis (LiDaKrA).

Actors of "classic" organized crime are increasingly using the Internet to plan and carry out criminal acts. A central problem in the detection of these crimes is the time-consuming and personnel-intensive research work. In most cases, the results have to be reconciled manually, as data is available in different contexts and formats. If there is a well-founded suspicion of a crime, automated evaluation of this data can facilitate the work of the investigating authorities.

Goals and innovations
In LiDaKrA, a software system is to be created that performs the search work in a partially automated manner. With this system, various data sources can be searched in a moment of suspicion and the results transferred into a uniform data format. The search results are meaningfully networked and related to facts of organized crime. Furthermore, research is conducted to determine whether criminal acts on the Internet are conspicuous by special patterns and procedures. Since different software systems are in use throughout Germany, the innovation consists of a central platform that can be used as "software as a service" by all security authorities.

Task of the University of Kassel
Particular attention is paid to the area of conflict between the protection of personal rights and the automated evaluation of data. In LiDaKrA, data is to be collected only on an ad hoc basis and for the purpose of law enforcement.... Thus, data is not to be collected continuously, but only queried and compiled from public sources when a crime is suspected. Permanent storage does not take place. The task of the University of Kassel is to ensure compliance with legal requirements, in particular from data protection law and police law, already during the development of this analysis tool. In addition, ethical and legal questions raised by the development and use of this data analysis tool by police and security authorities are to be answered. The legal support from the beginning of the development enables the LiDaKrA software system to be designed in a way that is as legally and constitutionally compatible as possible. In this way, the protection of the fundamental rights of those affected and the self-regulation of the police and security authorities can be promoted.

The research program is funded on the basis of the Federal Government's program "Research for Civil Security" within the framework of the BMBF announcement "Civil Security - Protection against Organized Crime".
