Abstract: The misuse of data crawlers and financial data has led to conflicts between data owners and controllers, which weakens the risk control mechanism of data flow and creates data gaps and inequality. Based on strengthening security protection of consumers' information, data development in the financial field should promote the orderly flow of data and realize the deep integration of system construction and law improvement. On the one hand, the development of financial data should adopt the mode of protective utilization to rectify the negative effect of excessive utilization and achieve multi-level efficiency in allocating rights and obligations. On the other hand, to regulate the crawling behavior of data crawlers, it is necessary to realize the reasonable separation of information development and privacy protection. In addition, it is helpful to clarify the differentiated allocation of the protection of information rights and privacy rights, strengthen the public law protection of financial consumer data and improve the scene confirmation and protection mechanism to realize the coordinated development of group protection and individual protection, as well as general rights and special rights.
