Step S101, receiving a transaction processing request, and obtaining the corresponding transaction message, server identification and biometric identification requirement identification.

In this embodiment, the execution subject of the transaction processing method (for example, it may be a server) may receive the transaction processing request through a wired connection or a wireless connection. The transaction processing request may be, for example, a request for transaction processing between multiple terminals. After receiving the transaction processing request, the execution subject may obtain the corresponding transaction message. Specifically, the transaction message may be, for example, a message corresponding to the payment amount. Obtain the server ID corresponding to the transaction processing request to call and connect to the corresponding server to prepare to receive transaction messages. The transaction processing request can also carry a biometric identification, which is used to indicate whether biometric identification is required. For example, when the biometric identification is Y, it indicates that biometric identification is required. When the biometric identification When marked as N, it indicates that biometric identification is not required. The embodiment of the present application does not specifically limit the biometric identification requirement.

Specifically, obtaining the corresponding transaction message includes: obtaining the terminal identification corresponding to the transaction processing request; obtaining the corresponding transaction data based on the terminal identification; performing signature calculation and encryption calculation on the transaction data to obtain the signature message field and the encrypted message field. text field; based on the signed message field and the encrypted message field, the full message encryption process is performed to obtain the transaction message.

For example, the transaction data obtained from the transaction on the corresponding terminal is acquired through the terminal identifier. The transaction data may be, for example, a credit card bill, consumption payment amount, etc., and the embodiment of the present application does not specifically limit the type of transaction data. As an example, the device terminal assembles a message based on the transaction data corresponding to the initiated transaction, performs signature calculation on the message based on the device terminal, obtains the signature information, and assembles the signature message field based on the signature information; Encrypt the text with base64 to get the encrypted message field, add the signed message field and the encrypted message field to generate the full message, encrypt the full message to get the transaction message, and then push it to the distributed message middleware EMQX.

Step S102, in response to the biometric identification requirement corresponding to the need for biometric identification, execute the biometric identification program, and in response to the success of the biometric identification, call the distributed message middleware to send the transaction message to the server corresponding to the server identification.

For example, when the biometric identification requirement is marked as Y, it indicates that biometric identification is required, and when the biometric identification requirement is identified as N, it indicates that biometric identification is not required. The embodiment of the present application does not specifically limit the biometric identification requirement.

Specifically, before performing the biometric identification procedure, the method further includes:

Step S304, in response to there is a registered image matching the biometric image among the registered images, determining that the biometric identification is successful.

When there is a profile matching the first profile in each of the second profiles, the registered image corresponding to the successfully matched second profile is determined as the registered image matching the biometric image, and a biometric identification success message is output.

Step S305, in response to successful biometric identification, call the distributed message middleware to send the transaction message to the server corresponding to the server identifier.

Biometric identification is successful when there is an image matching the biometric image in the registered image collection. When the biometric identification is successful, the execution subject can call the distributed message middleware to send the transaction message to the server corresponding to the server identifier.

The above-mentioned computer-readable medium carries one or more programs, and when the above-mentioned one or more programs are executed by a device, the device receives a transaction processing request, and obtains a corresponding transaction message, server identification and biometric requirement identification ; In response to the biometric identification corresponding to the need for biometric identification, the biometric identification program is executed, and in response to the success of the biometric identification, the distributed message middleware is invoked to send the transaction message to the server corresponding to the server identification; the receiving server The returned verification result information of the transaction message, in response to the fact that the verification result information corresponds to an unintercepted change, calls the server to execute a transaction processing process based on the transaction message.

The computer program product of the present application includes a computer program, and when the computer program is executed by a processor, the transaction processing method in the embodiment of the present application is implemented.

According to the technical solution of the embodiment of the present application, unified, automated, and simplified management of various types of terminal systems can be realized, and it can be applied to various platform systems, improving the efficiency and convenience of transaction processing, and reducing resource consumption.

The above specific implementation methods are not intended to limit the protection scope of the present application. It should be apparent to those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of this application shall be included within the protection scope of this application.
