Embodiment 5

As shown in FIG. 5, a payment method provided by a preferred embodiment of the present invention is applied to a payment system based on the same fund management server, and the method includes the following steps:

S201. The client sends payment request information to the fund management server, where the payment request information includes a payment amount, and the fund management server receives the payment request information sent by the client.

The payment request information is composed of a plurality of data packets, and at least includes merchant information, commodity information, and payment amount. It can also include client information such as customer IDs. The merchant information may directly be the merchant payment account, or may uniquely identify the merchant information (such as the merchant ID), and the fund management server searches the database for the bank account information corresponding to the merchant according to the unique identifier of the merchant. In a specific application, the account information of the merchant side should be confidential with respect to the client, so the merchant information is preferably a merchant ID, and the fund management server uses the relationship between the merchant ID and the payment account to query the merchant's payment account. That is to say, the client only needs to inform the merchant management server which merchant to pay for which commodity, and the fund management server can call the merchant's account to implement the corresponding payment operation.

The manner in which the client sends the payment request information to the fund management server can be performed in an existing manner, such as by using a digital signature or a digital envelope. Digital signature refers to the data obtained by the user encrypting the information digest of the original data with his or her private key. The information receiver obtains the information digest by decrypting the digital signature attached to the original information using the public key of the information sender, and can confirm whether the original information has been tampered with by comparing with the information generated by the original data received by the user. . This ensures the non-repudiation of data transmission. Digital envelopes use cryptographic techniques to ensure that only the intended recipient can read the content of the message. A single key cryptosystem and a public key cryptosystem are used in the digital envelope. The sender of the information first encrypts the information by using a randomly generated symmetric cipher, and then encrypts the symmetric cipher with the public key of the recipient. The symmetric cipher encrypted by the public key is called a digital envelope. When transmitting information, when the information receiver wants to decrypt the information, it must first decrypt the digital envelope with its own private key to obtain a symmetric password, in order to use the symmetric password to decrypt the obtained information. This ensures the authenticity and integrity of the data transmission.

S203, querying the credit account balance of the client account is sufficient, if not, step S204 is performed, otherwise step S207 is performed;
