The development of network finance makes the supervisory authority face an important choice. It is obviously inappropriate to use the past financial supervision methods to manage the network financial industry. To adapt to the new characteristics of network finance, it is required to establish new regulatory standards, adjust the regulatory structure and update technology, and innovate traditional financial regulatory means. The supervision of online finance can be divided into two major aspects: one is the supervision of online financial services provided by online financial institutions; The second is to supervise the impact of online finance on national financial security and other management fields. In view of the particularity of network finance, its supervision should be mainly reflected in the overall problems.
（1） Supervision on the service program and authenticity of online finance
In fact, online financial institutions can be more accurately defined as an advanced online financial service system, and the supervision of the accuracy, authenticity and compliance of financial services in this system should be the focus of online financial supervision. First of all, the business of online financial institutions should comply with the national financial policy, especially to control online financial institutions to use their low-cost advantages over traditional financial services to compete unjustly. Secondly, for various financial services provided by online financial institutions, due to different development characteristics and priorities among financial institutions, financial service content under similar names, especially if users of this service accept different agreements, will cause confusion in the whole service provision. Therefore, a set of standardized "industry service specifications" should be formed. Regulate various online financial services such as online payment, online insurance and online securities trading. One of the advantages of online finance is to greatly expand the scope of services to attract customers. Then the establishment of service standards is the basis for the integration of online financial resources. The formulation of these standards should be the responsibility of the highest regulatory authority, and these standards should be given a mandatory color.
As far as the authenticity supervision of services is concerned, an online financial transaction confirmation system should be established. For each online financial business, the user has the right to propose transaction confirmation. For example, users must be requested to give final confirmation through secure signed e-mail or other means, and the flow of each fund must be guaranteed by the final recipient. Bank confirmation is also required for transfer business between two accounts in the same bank. This is a necessary measure to ensure the safety and authenticity of financial transactions.
（2） Supervision on the security of network financial system
The most critical factor in the development of online finance is security. How to ensure transaction security is the key to the development of online finance. It is extremely necessary to force network financial institutions to adopt firewall, virtual safe and other encryption technologies to protect themselves and protect customers' interests from damage. The regulatory authority should set up a special technical committee to conduct qualification certification and daily supervision on the system security of online finance, propose regulatory norms for the system distribution security of online financial institutions, and require them to set up walls layer by layer according to the task requirements. From the whole Website Design From the height of security operation, we will implement network security control and management from nine security links, and consider network anti-virus together. We will conduct real-time and dynamic network testing, so as to strengthen network protection measures while constantly suffering attacks or accidents.
It should be realized that the system security supervision of network finance is always limited, and the possibility of network failure exists objectively. Therefore, it is also of great practical significance to stipulate the risk responsibility sharing mechanism of online financial institutions in terms of policy. For online finance, some losses are relatively easy to share responsibility, while others are very difficult, such as losses caused by irresistible disaster events and hacker intrusion. In the long run, regulators should let online financial institutions bear most of these risks to force financial institutions not to damage customers' interests under the pretext of highly technical system security.
（3） Supervise the rights and interests of consumers
In the face of online finance, consumers and customers are in a passive position of asymmetric information. Compared with online financial institutions, consumers are vulnerable groups in the context of online technology. In addition to consumers should pay attention to strengthening their own risk awareness, the initiative of risk control largely depends on regulators and online financial service providers.
Internet financial institutions should avoid using their own advantages of covert actions to promote unqualified services or low-quality and high-risk financial products to consumers, thereby harming the interests of consumers. Internet financial institutions have the obligation to keep customer information and account transaction information confidential. Without the customer's permission or the law enforcement requirements of specific law enforcement agencies, financial institutions cannot provide customer information to a third party. In addition, we should also consider the responsibilities corresponding to the characteristics of high-tech online financial services. As online financial services imply a commitment to efficient time use and convenient use, the compensation for damages by the responsible party when customers complete financial transactions through online finance should not only include compensation for the direct costs of market transactions, but also include reasonable compensation for the efficiency costs of market transactions. For example, the motivation of consumers to accept online banking business and participate in electronic currency is their convenience and efficiency, For indirect losses, due consideration should also be given to the financial institutions that promise to provide these facilities in advance.
（4） Supervision of crimes committed by means of network finance
The characteristics of online finance and e-commerce lie in the dispersion and concealment of sub users. You can enjoy all kinds of financial services and realize cross-border flow of capital by keying a string of codes to the account opened. This will facilitate criminal activities such as online "money laundering", private storage of public funds, tax evasion and tax evasion. Based on the rapid development of network finance, criminals will undoubtedly carry out full "network crime innovation". The early prevention and supervision of national central banks is an important part of the healthy development of the entire network security. In order to prevent online financial crimes, the Central Bank can pass legislation and establish its own digital authentication center to issue "online identity cards" representing the identity of network subjects to identify enterprises and individuals involved in online financial transactions, so as to strengthen the legitimacy review of the source and flow of funds into the network system.
