Big Data In Policing: Profiling, Patterns, and Out of The Box Thinking
Big Data, being a massive amount of data, which requires technologies, in-formation architecture and systems design, and analytical methods, has a significant impact on modern society and the development of strategies for the security area. This paper investigates the importance of Big Data in po-licing and discusses the challenges arising from its appliance to maintain public order. It’s presented a theoretical study, based on a literature review in the context of policing, that allows the establishment of the construct in which the Portuguese National Public Security developed its own Strategic Information System. For the study, some inclusion and exclusion criteria were used to narrow the gaps for a better understanding of the subject. Even though some questions arise from the use of the Big Data, such as pro-cessing, profiling, parsing algorithms that can conduct excessive normalisa-tions of the data, Big Data is leverage in policing and a tool of predictive policing.
