In recent years, with the advent of the big data era and the algorithmic society, the commercialuse of personal data has become more and more obvious, leading to frequent personal data leaks,especially in the financial industry, which has a high economic value. In the context of big data, financialprivacy has gradually evolved into financial information. Unlike other information, consumer financialinformation also has diversity and complexity, sensitivity and value, and privacy and publicity, so itcannot be equated with other information in terms of protection mechanisms. Although China hasestablished a civil and administrative legal regulation system for consumer financial information, civil andadministrative protection is far less vigorous than criminal protection. At the same time, the crimes in thecurrent criminal law can only indirectly protect consumer financial information, and have not formeda direct deterrent effect. In this regard, the criminal law should be extended to include the crime of“infringing on consumer financial information” in order to better regulate the infringement of consumerfinancial information in practice.
