[0072] After the user has completed the above preparations, the user must first log in to the payment system through the mobile terminal in the process of performing a specific transaction, and the login process is shown in Figure 1. The user sends a login request to the payment system through the mobile terminal, and the payment system checks whether the user's general transaction number is a registered user. If it is a registered user, it sends a random seed value for encryption. If it is a non-registered user, it prompts that the authentication fails, and Prompt the user to register. The user encrypts the login password with a random seed value through the mobile terminal. Even if the password is intercepted during transmission, it will not be cracked, ensuring the security of the password. The payment system decrypts the encrypted password after receiving it, and authenticates the password with the general transaction number. If the password is correct, it will send a successful login message, and if it is incorrect, it will pr...

Abstract
Purpose of the invention is to disclose secure general transaction system, which is capable of connecting to multiple bank system and diversified mobile terminals. Thus, mobile terminal possesses payment function and function of collection of payment. Main technique is to setup payment system between mobile terminal and bank system. Through payment system, mobile terminal can connect to multiple bank system to implement transaction. Through the payment system, security of transaction is guaranteed.
[0074] If the transaction is an ordinary payment, such as figure 2 Shown. After the user logs in, he submits the secondary virtual account of the account that needs to participate in the transaction to the payment system, and the submission process can also use encryption. The payment system completes the conversion between the universal transaction number and the payment system identification number according to the payment party's universal transaction number, and combines the payment system identification number and the submitted secondary virtual account number into a primary virtual account number and submits it to the banking system. The banking system generates a transaction serial number and random seed value for this transaction, and transmits the transaction serial number and random seed value back to the payment system, and the payment system transmits the transaction serial number and random seed value back to the mobile terminal of the payer. The payer’s mobile terminal encrypts the bank account password corresponding to the secondary virtual account through the random seed value, and submits complete transaction information including: transaction type, transaction amount, payee’s general transaction number, payer’s general transaction number, The second-level virtual account of the payer; the transaction information can also include the payee's name, transaction notes, etc. The payment system determines the ordinary payment according to the submitted transaction type, completes the conversion between the common transaction number of both parties in the transaction and the payment system identification number, and combines it with the default receiving account set by the payee and the secondary virtual account of the payer to form both parties to the transaction Fill in the corresponding position of the transaction form with the encrypted bank account password and corresponding transaction serial number, and submit the transaction form to the bank system after processing. The banking system completes the conversion between the primary virtual account and the actual account according to the primary virtual account of both parties in the transaction form, and authenticates the payer’s bank account participating in the transaction with the payer’s bank account password provided in the transaction form. After passing the legality authentication, it enters the general financial electronic transaction process, otherwise the transaction process ends. After the transaction process is over, the banking system returns the transaction serial number and transaction result to the payment system. If the transaction fails, it returns the reason for the transaction failure. The payment system records the transaction result and returns the transaction result to the payer’s mobile terminal. If the transaction fails, it also returns the transaction Reason for failure.

[0075] Method Example 2
[0076] When the transaction process is a bill transaction, such as image 3 As shown, when the user logs in to the payment system through the mobile terminal. The payer obtains the unpaid bill from the payment system. The bill is submitted to the payment system by other commercial systems through the standard interface provided by the payment system. The bill includes the validity period of the bill, the transaction amount, and the common transaction number of both parties to the transaction. information. It can also include the account information of the bill provider, the name of the bill provider, the party who pays the handling fee, the method of handling bill expiration, and the transaction amount. The bill processing method between the payment system and the commercial system should include bill submission, bill receipt, bill processing, and bill processing result feedback. In order to ensure complete information transmission, each processing adopts a request/response model. The payment submits the secondary virtual account of the account that needs to participate in the transaction to the payment system, and the submission process can also use encryption. The payment system completes the conversion between the universal transaction number and the payment system identification number according to the payment party's universal transaction number, and at the same time combines the payment system identification number and the submitted secondary virtual account number into a primary virtual account number and submits it to the banking system. The banking system generates a transaction serial number and random seed value for this transaction, and transmits the transaction serial number and random seed value back to the payment system, and the payment system transmits the transaction serial number and random seed value back to the mobile terminal of the payer. The payer’s mobile terminal encrypts the bank account password corresponding to the secondary virtual account with a random seed value, and submits complete transaction information including: transaction type, payer’s general transaction number, payer’s secondary virtual account and bill serial number ; Transaction information can also include transaction notes and so on. The payment system determines the bill payment according to the submitted transaction type and reads the bill serial number. The payment system reads the general transaction number and transaction amount of the payee according to the bill serial number. The payment system reads the general transaction number and the payee of both parties to the transaction. Set the default receiving account and the payer’s secondary virtual account to get the primary virtual account of both parties to the transaction, fill in the corresponding position of the transaction form together with the encrypted bank account password and the corresponding transaction serial number, and submit the transaction form to Banking system. The banking system completes the conversion between the primary virtual account and the actual account based on the primary virtual account of both parties in the transaction form, and authenticates the payer’s bank account participating in the transaction with the payer’s bank account password provided in the transaction form. The banking system completes the conversion between the primary virtual account and the actual account based on the primary virtual account of both parties in the transaction form, and authenticates the payer’s bank account participating in the transaction with the payer’s bank account password provided in the transaction form. After the legality authentication is passed, it enters the general financial electronic transaction process, otherwise the transaction process ends. After the transaction process is over, the banking system returns the transaction serial number and transaction result to the payment system. If the transaction fails, it returns the reason for the transaction failure. The payment system records the transaction result and returns the transaction result to the payer’s mobile terminal. If the transaction fails, it returns the transaction at the same time. Reason for failure.
