Application of Big Data Technology in Criminal Investigation

Abstract

In order to improve the efficiency of criminal investigation and ensure the objectivity of investigation behavior, big data is widely used in the field of investigation. Through the search, query, comparison and analysis of various big data in the public security organ's own data system and social data system, criminal clues can be found. This will be able to detect criminal evidence, capture suspect and detect crime. However, the application of big data in criminal investigation also has some problems, such as "data island", backward big data technology, lack of big data experts, violation of citizens' privacy and threat to national security. Therefore, we should break the data barrier and break the dilemma of "data island". Therefore, the judiciary should develop big data technology and train big data talents in order to strengthen big data information legislation and protect citizens' privacy and national security.
