[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0038] The term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0039] In order to solve the problem of low efficiency in reviewing transaction information when the screening process changes in the prior art, the embodiments of the present application provide an information processing method, apparatus, device, and medium. After obtaining the first transaction information, the method mainly screens the first transaction information through multiple preset screening processes according to the execution order of multiple preset screening processes configured using structured query statements, and obtains the screening results corresponding to each preset screening process. Then, when the screening results corresponding to each preset screening process meet the preset conditions, the first business system can be controlled to stop the transaction operation corresponding to the first transaction information. In this way, by configuring the execution order of multiple preset screening processes using structured statements, the workload can be reduced, and the efficiency of reviewing transaction information can be improved.

[0040] The information processing method, apparatus, device, and storage medium provided in the embodiments of the present application are described in detail below with reference to specific embodiments in conjunction with the accompanying drawings.

[0041] First of all, it should be noted that in the embodiment of the present application, the information processing method can be executed through the transaction screening system 100, and the transaction screening system 100 includes an interface receiving module 11, a first screening module 12, a second screening module 13, a database 14 and an end-of-day backtracking module 15.

[0042] Among them, the interface receiving module can receive the transaction information sent by the first business system, and convert the data format of the transaction information into the data format of any screening engine interface in the first screening module, and add the converted transaction information to the Java LinklockingQueue queue, and send the converted transaction information to the first screening module for screening through a multi-threaded queue.

[0043] The first screening module can use the preset screening rules and / or the first blacklist to screen the converted information, and when the converted transaction information hits the preset screening rules and / or the first blacklist, send the transaction information to the second screening module through the interface receiving and forwarding module; or when the converted transaction information does not hit the preset screening rules and the first blacklist, feedback the screening results to the first business system through the interface receiving module, so that the first business system continues to execute the transaction operation corresponding to the transaction information.

[0044] The second screening module can use its own multiple screening processes to review the transaction information to determine whether the transaction information is abnormal transaction information, and send the final review result to the first business system, so that the first business system can stop the transaction operation corresponding to the transaction information if it determines that the transaction information is abnormal transaction information, or continue to perform the transaction operation corresponding to the transaction information if it determines that the transaction information is not abnormal transaction information.

[0045] The database can use structured statements to configure the execution order of multiple screening processes. In addition, the process position information involved in multiple screening processes, the information between process positions, the flow condition information, and the role information corresponding to the process positions can also be configured by the database.

[0046] The end-of-day backtracking module is used to obtain a second blacklist within a preset time period to update the first blacklist based on the obtained second blacklist. In addition, the user information in the transaction information stored in the database can also be screened. If it is determined to be abnormal user information, the abnormal user information will be sent to the second business system to restrict business operations related to the abnormal user.

[0047] In addition, it should be noted that the interface receiving module can also replace the first screening module to perform part of the screening actions in the case of abnormality of the first screening module or in the case of large changes in the screening engine interface of the first screening module, such as screening of high-risk countries, self-defined screening message field and type screening.

[0048] Based on Figure 1 the architecture diagram of the transaction screening system shown in the figure, Figure 2 is a flow diagram of an information processing method provided by an embodiment of the present application. The embodiment of the present application takes the transaction screening system as an execution subject and details the information processing method provided by the embodiment of the present application.

[0049] As Figure 2 shown, the method can specifically include the following steps:

[0050] S210, obtaining first transaction information.

[0051] The first transaction information can be transaction information between any two users, such as user A transferring X yuan to user B.

[0052] Specifically, the first transaction information about the user can be directly obtained in the case that the user generates transaction information.

[0053] S220, screening the first transaction information through a plurality of preset screening processes to obtain a screening result corresponding to each preset screening process.

[0054] The preset screening process is a process for screening and auditing the first transaction information, which is set in advance based on experience. The execution order of the plurality of preset screening processes is configured by using a structured query statement. The screening result corresponding to each preset screening process includes two results of “pass” and “fail”, which are used to indicate whether the first transaction information passes the preset screening process. In addition, the screening result can also be represented by “yes” and “no”, or “1” and “0”, wherein “1” indicates that the first transaction information passes the preset screening process, and “0” indicates that the first transaction information fails the preset screening process. The representation of the screening result will not be described in detail here.

[0055] Specifically, the transaction screening system can first configure in excel, and use an automatic generation tool to generate a structured query statement to configure the execution order of the plurality of preset screening processes. Then, the plurality of preset screening processes are used to screen the obtained first transaction information one by one according to the execution order of the plurality of preset screening processes configured by using the structured query statement, and a screening result corresponding to each preset screening process is obtained.

[0056] S230: When the screening result corresponding to each preset screening process meets the preset conditions, control the first business system to stop the transaction operation corresponding to the first transaction information.

[0057] The preset condition is a condition preset based on actual experience, and is used to determine whether the first transaction information is abnormal transaction information.

[0058] In an example, assuming that the preset condition can be that the number of "passed" screening results among multiple screening results is greater than a preset value, or that the number of "passed" screening results among multiple screening results is greater than the number of "failed" screening results, if the screening results corresponding to each preset screening process meet the preset condition, it indicates that the first transaction information has a greater transaction risk, and it is necessary to send the screening result of the first transaction information as abnormal transaction information to the first business system, and control the first business system to stop the transaction operation corresponding to the first transaction.

[0059] In addition, in one embodiment, the above-mentioned information processing method further includes:

[0060] When the screening result corresponding to each preset screening process does not meet the preset conditions, the first business system is controlled to continue the transaction operation corresponding to the first transaction information.

[0061] In this embodiment, when the screening results corresponding to each preset screening process obtained do not meet the preset conditions, the transaction screening system can send a screening result that the first transaction information is not abnormal transaction information to the first business system, and control the first business system to continue to execute the transaction operation corresponding to the first transaction information based on the screening result.

[0062] In an embodiment of the present application, after obtaining the first transaction information, the first transaction information is screened through multiple preset screening processes based on the execution order of multiple preset screening processes configured using structured query statements, and a screening result corresponding to each preset screening process is obtained. Then, when the screening result corresponding to each preset screening process meets the preset conditions, the execution order of the multiple preset screening processes configured in the first industry can be controlled. In this way, not only the workload can be reduced, but also the review efficiency of the transaction information can be improved.

[0063] In order to accurately screen transaction information, in one embodiment, before the above-mentioned S210, Figure 3 As shown, the above-mentioned information processing method also includes:

[0064] S310, receiving multiple second transaction information sent by the first business system.

[0065] The first business system is a system involving user transactions, and the second transaction information includes user information corresponding to the second transaction information.

[0066] Specifically, when the second transaction information is detected in the first business system, the transaction screening system can receive multiple pieces of second transaction information sent by the first business system.

[0067] S320: Convert the data formats of the plurality of second transaction information to obtain second transaction information that is consistent with the data format of any one of the plurality of screening engine interfaces.

[0068] After the transaction screening system receives multiple second transaction information, the data format of each second transaction information needs to be converted so that the data format of each second transaction information in the multiple second transaction information is consistent with the data format of any screening engine interface in the multiple screening engine interfaces in the transaction screening system.

[0069] S330: Using a preset screening rule and / or a first blacklist, the plurality of second transaction information converted into data formats are screened to obtain the first transaction information.

[0070] The preset screening rules are pre-set conditions based on actual experience and are used to screen abnormal transaction information. For example, the amount of a single transfer cannot exceed a preset value, or the number of transfers within a preset time period cannot exceed a preset number, etc. There are no excessive restrictions here. The first blacklist is a list used to screen abnormal users.

[0071] After the transaction screening system obtains the multiple second transaction information in the converted format, it can screen the abnormal transaction information in the multiple second transaction information based on preset screening rules, or it can screen the multiple second transaction information based on the first blacklist by calculating the matching degree between the user information in each second transaction information and the abnormal user information in the first blacklist.

[0072] In this embodiment, by receiving multiple second transaction information sent by the first business system and converting the data formats of the multiple second transaction information, second transaction information with the same data format as any one of the multiple screening engine interfaces can be obtained. Then, the multiple second transaction information can be screened based on preset screening rules and / or the first blacklist, so as to more accurately screen out abnormal transaction information.

[0073] In another embodiment, the above-mentioned information processing method further includes:

[0074] A second blacklist within a preset time period is obtained, so as to update the first blacklist according to the second blacklist.

[0075] In this embodiment, the transaction screening system can retrieve new entries from the second blacklist from the internet or other channels at predetermined intervals, thereby updating the first blacklist based on the second blacklist. This allows for more accurate screening of abnormal transaction information. The predetermined period is a time period pre-set based on empirical data, and can be a day, a month, or other period, and is not specifically limited herein.

[0076] In a specific embodiment, the above-mentioned information processing method further includes:

[0077] Determining first user information whose user information corresponding to the transaction information stored in the database is consistent with the user information in the second blacklist;

[0078] The first user information is stored in a second business system, so that the second business system can control business operations of the user corresponding to the first user information.

[0079] In this embodiment, after obtaining the second blacklist within a preset time period, the first user information corresponding to the transaction information stored in the database is determined to be consistent with the user information on the second blacklist, i.e., abnormal user information. This first user information can then be stored in the second business system so that the second business system can subsequently control the business operations of the user corresponding to the first user information. The second business system can be a system for maintaining customer information or a system for generating risky transaction reports, without further limitation. In this way, by screening historical transaction information stored in the database based on the second blacklist, the omission of abnormal transaction information or abnormal users is avoided, thereby effectively achieving the screening of transaction information.

[0080] Based on the same inventive concept, the embodiment of the present application also provides an information processing device. Figure 4 Explanation
