On the Protection of Personal Data Information in Big Data Investigation Activities

In the context of the vigorous development of big data and network communication technologies, the universality of personal data information processing, the openness of concept definitions, and the potential risks in practice have led to theoretical and practical changes in the definition of personal data information. With the widespread use of big data technology in criminal investigations, the theoretical and practical activities of big data investigation have gradually formed. Big data investigation activities are often accompanied by infringements on citizens' personal data and other legitimate rights and interests. At present, the traditional model of personal data information protection cannot restrict the code of conduct in big data investigation activities. For this reason, it is necessary to introduce a comprehensive governance model, which mainly includes relative control of individuals, balance of multiple interests and dynamic risk adjustment. Etc., and focus on the transformation of the legal protection model of personal information.
