Description

Technical Field

[0001] The present invention relates to the field of distributed technologies, and in particular, to a transaction authorization method, device, and system in a distributed system. Background Art

[0002] This section aims to provide background or context for the embodiments of the present invention described in the claims. The description herein is not admitted to be prior art merely because it is included in this section.

[0003] In a distributed system, when processing a transaction that may or may not require authorization or may require authorization at multiple locations, in order to improve efficiency, each server independently submits the transaction. If an error occurs in a subsequent transaction, a rollback request is sent to the servers that have already submitted the transaction.

[0004] In bank transactions, some transactions can be determined whether authorization is required based on the input, and some require judgment in the program logic. In this case, if authorization is required midway, the servers in the distributed system that have already run have already submitted the transaction, and each needs to be rolled back one by one. This makes the processing very cumbersome. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer and more understandable, the following will further describe the embodiments of the present invention in detail with reference to the drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0045] After analysis, the inventor found that in the current distributed system, the operation for processing a transaction that may not require authorization or may require authorization in multiple places is: each server submits the transaction separately, and if the subsequent transaction fails, a rollback request is sent to the submitted server. However, in banking transactions, some transactions can determine whether authorization is required based on the input, and some transactions require judgment in the program logic. In this case, if authorization is required in the middle, the servers in the distributed system that have been running before have already submitted the transaction and need to be rolled back one by one. Based on this, the inventor proposes a transaction authorization method in a distributed system. Compared with the solution in the prior art that requires a transaction rollback when the transaction encounters an authorization point, this method can simplify the transaction authorization steps, improve transaction authorization efficiency, shorten transaction processing time, and reduce costs.

[0046] Figure 1 The following is a flow chart of a transaction authorization method in a distributed system according to an embodiment of the present invention, which is applied to an authorization center server. The method includes the following steps:

[0047] Step 101: receiving a transaction authorization trial calculation request initiated by a transaction initiating end device;

[0048] Step 102, retrieving the authorization point information of the transaction involved in the transaction authorization trial calculation request;

[0049] Step 103: Send the authorization point information to the corresponding authorization verification server;

[0050] Step 104: Receive the authorization point information that has passed the verification fed back by the authorization verification server;

[0051] Step 105: Send the verified authorization point information to the transaction initiating end device, so that the transaction initiating end device can initiate an authorized transaction request to the transaction server after performing authorization processing according to the verified authorization point information.

[0052] Depend on Figure 1As can be learned from the process shown, in the embodiment of the present invention, the authorization center server receives a transaction authorization trial calculation request initiated by a transaction initiating end device; retrieves authorization point information of the transaction involved in the transaction authorization trial calculation request; sends the authorization point information to the corresponding authorization verification server; receives the authorization point information passed in the verification feedback by the authorization verification server; and sends the authorization point information passed in the verification to the transaction initiating end device, so that after the transaction initiating end device performs authorization processing according to the authorization point information passed in the verification, it can initiate an authorized transaction request to the transaction server; thus, through transaction authorization trial calculation and verification, it is convenient to complete authorization processing before the transaction. Compared with the solution in the prior art that still needs to perform transaction rollback when the transaction encounters an authorization point, it can simplify the transaction authorization steps, improve the transaction authorization efficiency, shorten the transaction processing time, and reduce costs.

[0053] Specifically in implementation, the authorization center server first receives a transaction authorization trial calculation request initiated by a transaction initiating end device, then after retrieving the authorization point information of the transaction involved in the transaction authorization trial calculation request, sends the authorization point information to the corresponding authorization verification server; and then receives the authorization point information passed in the verification feedback by the authorization verification server.

[0054] In one embodiment, retrieving the authorization point information of the transaction involved in the transaction authorization trial calculation request may include, for example: retrieving one or more authorization point information of the transaction involved in the transaction authorization trial calculation request;

[0055] Sending the authorization point information to the corresponding authorization verification server may include, for example: sending each authorization point information to the corresponding authorization verification server respectively;

[0056] Receiving the authorization point information passed in the verification feedback by the authorization verification server may include, for example: receiving the authorization point information passed in the verification feedback by each authorization verification server respectively.

[0057] In one embodiment, the authorization point information is all information related to this embodiment involved in the authorization point, and may include, for example: authorization point identifier, number of authorizations, and authorization level, etc. Those skilled in the art should know that the content of the authorization information can be selected according to actual needs.

[0058] Finally, send the authorization point information passed in the verification to the transaction initiating end device, so that after the transaction initiating end device performs authorization processing according to the authorization point information passed in the verification, it can initiate an authorized transaction request to the transaction server.

[0059] Figure 2 It is a schematic flowchart of a transaction authorization method in a distributed system in an embodiment of the present invention, applied to the process of a transaction initiating end device. The method includes the following steps:

[0060] Step 201: Send a transaction authorization trial calculation request to the authorization center server;

[0061] Step 202: Receive the authorized point information passed the verification feedback by the authorization center server. Among them, the authorized point information is the authorized point information of the transaction involved in the transaction authorization trial calculation request retrieved by the authorization center server, and the authorized point information passed the verification is obtained by the authorization center server submitting the authorized point information to the corresponding authorization verification server for verification;

[0062] Step 203: Perform authorization processing according to the authorized point information passed the verification;

[0063] Step 204: Send an authorized transaction request to the transaction server.

[0064] From Figure 2 the process shown, in the embodiment of the present invention, the transaction initiating end device sends a transaction authorization trial calculation request to the authorization center server; receives the authorized point information passed the verification feedback by the authorization center server. Among them, the authorized point information is the authorized point information of the transaction involved in the transaction authorization trial calculation request retrieved by the authorization center server, and the authorized point information passed the verification is obtained by the authorization center server submitting the authorized point information to the corresponding authorization verification server for verification; performs authorization processing according to the authorized point information passed the verification; sends an authorized transaction request to the transaction server; thus, through transaction authorization trial calculation and verification, it is convenient to complete authorization processing before the transaction. Compared with the existing technology where transaction rollback is still required when the transaction encounters an authorized point, the transaction authorization steps can be simplified, the transaction authorization efficiency can be improved, the transaction processing time can be shortened, and the cost can be reduced.

[0065] Specifically in implementation, first, the transaction initiating end device sends a transaction authorization trial calculation request to the authorization center server; then receives the authorized point information passed the verification feedback by the authorization center server. Among them, the authorized point information is the authorized point information of the transaction involved in the transaction authorization trial calculation request retrieved by the authorization center server, and the authorized point information passed the verification is obtained by the authorization center server submitting the authorized point information to the corresponding authorization verification server for verification.

[0066] In one embodiment, the authorized point information is all the information related to this embodiment involved in the authorized point, for example, it may include: authorized point identifier, number of authorizations, and authorization level, etc. Those skilled in the art should know that the content of the authorization information can be selected according to actual needs.

[0067] Then, perform authorization processing according to the authorized point information passed the verification.

[0068] In one embodiment, performing authorization processing according to the authorized point information passed the verification may include:

[0069] According to the highest authorization level, the authorization point identifier, and the number of authorization times in each authorization point information, authorization processing is performed for each authorization point involved in the transaction. Those skilled in the art should be aware that the determination conditions here are only for this embodiment, and other conditions can be selected according to actual needs.

[0070] Finally, an authorized transaction request is sent to the transaction server.

[0071] Figure 3 This is a specific example diagram of the transaction authorization method in the distributed system in the embodiment of the present invention. As Figure 3 shown, the devices for performing transaction authorization in this example may include: a transaction initiation device, an authorization center server, Server A, Server B, Server m, and Server n. Among them, the transaction server includes Server A and Server B, and the authorization verification server includes Server m and Server n.

[0072] In this example, the transaction authorization method in the distributed system includes:

[0073] The transaction initiation device sends a transaction authorization trial calculation request to the authorization center server; the authorization center server retrieves all authorization point information related to the transaction in the transaction authorization trial calculation request. For example, it includes two pieces of authorization point information: authorization point information x and authorization point information y. Among them, authorization point information x should be verified by Server m, and authorization point information y should be verified by Server n; the authorization center server sends authorization point information x to Server m and sends authorization point information y to Server n. Assuming that both authorization point information x and authorization point information y pass the verification, Server m feeds back authorization point information x to the authorization center server, and Server n feeds back authorization point information y to the authorization center server; the authorization center server sends authorization point information x and authorization point information y to the transaction initiation device; after the transaction initiation device processes the authorizations required for authorization point information x and authorization point information y, it submits an authorized transaction request to the transaction server: Server A and Server B perform transactions, and each transaction server completes the corresponding processing and submits the transaction. The advantage of doing this is that the authorization center server is used to check whether the transaction request requires authorization; the transaction initiation device does not need to make a separate transformation for authorization processing, and the authorization trial calculation has been separately processed before transaction processing; the authorization center server centrally manages the authorization point information and maintains all authorization point information of the transaction and the authorization verification server corresponding to each authorization point information.

[0074] The embodiments of the present invention also provide an authorization center server, as described in the following embodiments. Since the principles of these authorization center servers for solving problems are similar to the transaction authorization method in a distributed system applied to the authorization center server, the implementation of these authorization center servers can refer to the implementation of the transaction authorization method in a distributed system applied to the authorization center server, and the repeated parts will not be elaborated.
