As traditional policing methods struggle with the complexity of cybercrime, European Law Enforcement Agencies (LEAs) are required to employ advanced technologies to combat digital crime while upholding EU regulations about privacy and data protection. They often struggle to hold on with the fast-changing modus operandi of criminals and terrorists who exploit the benefits of digital technologies. Moreover, LEAs must deal with issues of public trust that undermine their efforts. To tackle these challenges, the project PRESERVE empowers law enforcement officers with innovative solutions that adhere to privacy standards and facilitate the access to actionable intelligence. The PRESERVE toolkit implements Big Data and AI models, while integrating bias mitigation and ensuring compliance with existing ethical and legal frameworks, to enable crime prevention and detection. Thus, PRESERVE seeks to improve the allocation of police resources, promote predictive policing, and enable the timely and effective detection of cybercrime and terrorism by developing a legally compliant technological framework based on AI and Big Data methods.
