Preferably, the upload unit 30 retrieves the pre-stored information from the blockchain 40 by: the uploading unit 30 generates a calling instruction according to the user information, the block chain 40 calls the corresponding user information according to the calling instruction, if the calling is successful, the pre-stored information is sent to the uploading unit 30, the uploading unit 30 sends the pre-stored information to the identifying unit 20, the identifying unit 20 compares the user information with the pre-stored information, if the user information and the pre-stored information are consistent, the first authentication is passed, otherwise, the first authentication is failed; if the calling fails, a failure instruction is generated and sent to the uploading unit 30, the uploading unit 30 generates an encryption instruction and sends the encryption instruction to the encryption unit 60, and the encryption unit 60 encrypts the user information according to the encryption instruction. Further, the encryption unit 60 is further configured to decrypt the pre-stored information, and the process of the uploading unit 30 sending the pre-stored information to the identification unit 20 may further include: the upload unit 30 transmits the pre-stored information to the encryption unit 60, and the encryption unit 60 decrypts the pre-stored information and transmits the decrypted pre-stored information to the identification unit 20.
In a more specific embodiment, the first authentication includes identity authentication and credit authentication. The identification may be identified by pre-stored information stored in the blockchain 40, and the pre-stored information may include an identification card (or a user name, a mobile phone number, a passport, etc.) and a password (or a fingerprint, a human face, a signature, etc.) filled in by the user who logs in the user terminal 50 for the first time. The pre-stored information may also include crime records, credit records, debt situations, etc. corresponding to the user, and these information may be input into the blockchain 40 through other ports, such as ports of public security departments, banks, etc., and the credit authentication may be identified through these information. The identity authentication ensures the account safety of the actual user, avoids the loss of the user caused by number stealing, and the credit authentication can monitor the old dependence of the lost people.
In a more specific embodiment, the second authentication includes transaction exception identification. Preferably, the transaction anomaly identification includes transaction authenticity and legitimacy identification, such as: whether the unit price of the traded product is abnormally higher or lower than the market price, whether the product involved in the trade is in the operation range of the corresponding financial trading company, whether the trade mark is abnormal, and the like, so that the market fluctuation caused by the abnormal unit price of the traded product can be effectively avoided, illegal persons can be prevented from washing black money through financial trading, and the financial trading market is finally supervised.
Preferably, the transaction information includes: the information of both sides of the transaction (user and financial transaction company), the time address of the transaction, the product of the transaction, the unit price of the product of the transaction, the total price of the transaction and the like, and all the transaction information can be encrypted by adopting an encryption algorithm, so that the information leakage is avoided.
Furthermore, the invention can avoid writing wrong information into the block chain 40 from the source by means of the first authentication and the second authentication, thereby reducing the probability of correcting the error in the block chain 40.
