Data sharing and security are complementary and mutually reinforcing. On one hand, data sharing must prioritize security as an important prerequisite. Reducing the risks of data leakage and misuse will encourage businesses and consumers to participate in data sharing, allowing them to enjoy the benefits of development with peace of mind. At the same time, sharing data resources and enhancing the value and efficiency of data usage will also promote the advancement of data security technologies. Data needs to be "used" effectively, but it also needs to be "managed" better. Relevant departments should promptly assess various new situations that arise in practice, continuously optimize regulatory measures, enhance digital regulatory capabilities, and consistently improve data security levels. Overall, under the premise of complying with laws and regulations and ensuring information security, steadily advancing various data integration applications will promote the high-quality development of digital finance and provide more high-quality services for economic and social development
