The rapid growth of big data technology has become a major trend affecting the pattern of world development. Big data criminal investigation is a new type of criminal detection used extensively in the course of police practice at home and abroad. Its emergence indicates a trend in criminal justice towards ensuring security at the expense of privacy and exchanging rights for information. Big data criminal investigation highlights the backwardness and dysfunction of the traditional framework of legal norms, evident in doubts about the legal attributes of such investigation and the obvious limitations of techniques for distinguishing data content from metadata. This leaves a vacuum in the regulation of investigative power at the preliminary stage of investigation. Big data criminal investigation itself is a double-edge sword; in order to forestall the possible abuses it may entail in terms of deep and broad interventions in basic civil rights, big data criminal investigation should be brought under the necessary legal control. We therefore propose adopting a dual regulatory approach comprising investigative and data norms, selectively adopting the traditional normative framework of the principle of legality and the principle of proportionality, and at the same time supplementing it with other legal principles and mechanisms concerning the protection of personal information and data.

大数据刑事侦查的法律控制

大数据技术的快速发展已成为影响世界发展格局的主要趋势。大数据刑事侦查是一种新型的侦查犯罪手段，在国内外警务实践中得到了广泛的应用。它的出现表明了刑事司法的趋势，即以牺牲隐私和交换信息权利为代价来确保安全。大数据犯罪调查凸显了传统法律规范框架的落后性和功能失调，令人怀疑这种调查的法律属性以及区分数据内容和元数据的技术的明显局限性。在调查的初期阶段，这在调查权的调节上留下了真空。大数据刑事调查本身就是一把双刃剑。为了防止对基本民权进行深入和广泛干预可能造成的滥用，应将大数据刑事调查置于必要的法律控制之下。因此，我们建议采用包括调查和数据规范的双重监管方法，有选择地采用合法性原则和相称性原则的传统规范性框架，同时以其他有关保护个人信息的法律原则和机制作为补充和数据。
