Detailed Description
As discussed in the background, there is a need for an accurate and efficient method for identifying financial data anomalies.
The inventor of the present invention has found that, in the prior art, a large amount of financial data is usually directly analyzed and processed to determine whether there is an inappropriate financial behavior. However, since the financial data is usually massive, problems such as data errors or data loss usually occur in the processes of acquisition, storage and transmission, and if these problems are not identified and processed, errors may occur in the results of subsequent data analysis and processing.
In order to solve the above technical problem, an embodiment of the present invention provides a method for identifying financial data anomalies. In the scheme of the embodiment of the invention, the identification request and the rule description file are obtained, wherein the rule description file comprises a target data table, an exception type and a method description statement. Since the target data table is a data table to which the data to be identified belongs in the target database, and the identification request includes address information of the target database, the data in the target data table can be read from the target database. Further, since the method description statement is used for describing the method for identifying the exception and the method description statement is determined according to the exception type, the data in the target data table is subjected to exception identification according to the method description statement, an identification result corresponding to the exception type can be obtained, and the identification result comprises the position of the exception data in the target data table. Therefore, abnormal data in the target data table can be accurately and efficiently identified.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a method for identifying financial data anomalies according to an embodiment of the present invention. The financial data may be various data for financial statistics, financial analysis, for example, transaction data, financial data of a company entity, and the like, but is not limited thereto. It should be noted that, in the solution of the embodiment of the present invention, the abnormality that needs to be identified is not an abnormality caused by an inappropriate financial transaction behavior, for example, whether an abnormality caused by a money laundering behavior exists in the financial data is not identified, but whether the financial data is standardized data is identified before identifying whether an abnormality caused by an inappropriate financial transaction behavior exists, so that the user can correct the financial data according to the identification result, which is beneficial to accurately identifying whether an abnormality caused by an inappropriate financial transaction behavior exists in the financial data subsequently. In other words, the anomaly to be identified in the embodiment of the present invention is a case where the financial data in the database is inconsistent with the standardized financial data.
In particular, user terminal 11 may be coupled to computing platform 12 for data interaction with computing platform 12. The user terminal 11 may also be coupled to a plurality of databases 13 for data interaction with the plurality of databases 13. Wherein a plurality of databases 13 may be used to store financial data. It should be noted that, the computing platform 12 may be configured to execute the method for identifying the financial data abnormality in the embodiment of the present invention, before executing the method for identifying the financial data abnormality, the computing platform 12 is not connected to the database 13, and during executing the method for identifying the financial data abnormality, the computing platform 12 may obtain address information of a target database from the user terminal 11, establish a connection with the target database according to the address information of the target database, and obtain the financial data from the target database and identify the abnormality. The target database may be any one of the databases 13, and the target database may be determined by the user terminal 11.
Further, the user terminal 11 may also be connected with a third party terminal 14 to perform data interaction with the third party terminal 14. In a specific example, the user terminal 11 may obtain the rule description file from the third party terminal 14 and send the rule description file to the computing platform 12, so that the computing platform 12 performs the anomaly identification on the financial data according to the rule description file, but is not limited thereto.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for identifying financial data anomalies according to an embodiment of the present invention. The method may be performed by a computing device, which may be any of various existing devices with data receiving and processing functions, such as, but not limited to, a server, and the like, and may also be, for example, the computing platform 12 shown in fig. 1, and the like. By the method for identifying financial data abnormity shown in fig. 2, abnormal data in the target database can be accurately and efficiently identified. The method of identifying financial data anomalies illustrated in FIG. 2 may include the steps of:
step S201: acquiring an identification request and a rule description file;
step S202: reading data in the target data table from the target database;
step S203: and performing exception identification on the data in the target data table according to the method description statement to obtain an identification result.
It is understood that in a specific implementation, the method may be implemented by a software program running in a processor integrated within a chip or a chip module; alternatively, the method can be implemented in hardware or a combination of hardware and software.
In the specific implementation of step S201, the identification request and the rule description file may be obtained from the outside, for example, the identification request and the rule description file may be obtained from the user terminal 11 shown in fig. 1, where the rule description file may be obtained by the user terminal 11 from the third party terminal 14. It should be noted that, the order of acquiring the identification request and the rule description file is not limited in the embodiment of the present invention.
Specifically, the identification request may include address information of the target database, and a connection may be established with the target database according to the address information of the target database.
Further, the rule description file may include identification information of a target data table, where the target data table is a data table to which data to be identified belongs in the target database, and the identification information is used to uniquely determine the target data table. For example, if the data to be identified is transaction data, the target data table may be a transaction data table in the target database, and the identification information may be a name of the data table, but is not limited thereto.
Further, the rule description file may further include exception types and method description statements, where the method description statements and the exception types are in one-to-one correspondence, and the method description statements may be used to describe a method for identifying a corresponding exception type, in other words, the method description statements may be determined according to the exception types. The specific form of the method description statement may be determined according to the type of the target database, for example, if the target database is a MySQL database, the method description statement may be an sql statement. It should be noted that the rule description file may be encrypted in advance, for example, the rule description file may be encrypted by the third party terminal 14 in fig. 1, and after the rule description file is obtained, the rule description file may be decrypted first.
In a specific implementation of step S202, data in the target data table may be read from the target database. Further, whether the data in the target data table has an exception of the storage structure can be identified.
Referring to FIG. 3, FIG. 3 is a partial flow diagram illustrating another method for identifying financial data anomalies according to an embodiment of the present invention. Another method for identifying financial data anomalies, illustrated in FIG. 3, may include the steps of:
step S301: reading preset storage structure information of the target data table;
step S302: judging whether the field attribute of the data in the target data table is consistent with the standard field attribute according to the preset storage structure information to obtain a judgment result;
step S303: and sending the judgment result to the user terminal.
It should be noted that steps S301 to S303 may be executed after step S202 and before step S203.
In the implementation of step S301, the preset storage structure information may be obtained from the outside, for example, from the user terminal 11 in fig. 1, or may be stored in a local storage device in advance.
The preset storage structure information may be used to describe a standard storage structure of data in the target data table. Specifically, the preset storage structure information may include standard field attributes of the target data table, where the standard field attributes may include, but are not limited to, a standard field name, a standard field type, a standard field length, and the like. The standard field name is used to indicate the type of information to which each column of data in the target data table belongs, and for example, the standard field name may be: time, transaction amount, customer account number, and the like. The standard field type is a type of data belonging to the field, and may be, for example, a binary data type, a character data type, a Unicode data type, a currency data type, and the like, but is not limited thereto. The standard field length is used to indicate the size of the storage space occupied in the database by the data belonging to the field. And the standard field name, the standard field length and the standard field type have corresponding relation.
Further, the preset storage structure information may further include a standard index and a preset padding value of the target data table, where the preset padding value is a padding value preset at a data missing position in the target data table.
In the specific implementation of step S302, it may be determined whether the field attribute of the data in the target data table is consistent with the standard field attribute. Specifically, it may be determined whether each field name of the data in the target data table is consistent with the standard field name, in other words, it may be determined whether each of the plurality of standard field names can be found in the target data table, and if not, the standard field name that cannot be found in the target data table may be used as a part of the determination result.
Further, for each standard field name found in the target data table, it may be determined whether the type of the data belonging to the standard field name is the standard field type corresponding to the standard field name, and whether the length of the data is consistent with the standard field length corresponding to the standard field name, and the position of the data with the type inconsistent with the standard field type and the financial data with the length inconsistent with the standard field length in the target data table is used as a part of the determination result.
Further, whether the actual index of the target data table is consistent with the standard index can be judged. Specifically, a plurality of standard indexes may be looked up in the index information of the target data table, in other words, it may be determined whether the actual index of the target data table includes a plurality of standard indexes, and if not, the standard index that is not included may be taken as part of the determination result. It should be noted that, the embodiment of the present invention does not limit the order of judging the field attribute and the index.
Further, after determining whether the field attribute of the data is consistent with the standard field attribute, it may also be determined whether data missing exists in the data whose field attribute of the data in the target data table is consistent with the standard field attribute, if so, it is determined whether an actual padding value at the missing position is consistent with a preset padding value, and if the actual padding value is not consistent with the preset padding value, a position of the actual padding value in the target data table may be used as a part of the determination result.
In a specific implementation of step S303, the determination result may be sent to the user terminal, so that the user terminal corrects the data that does not satisfy the preset storage result information.
Further, update data may be acquired from the user terminal, the update data being determined according to the determination result, and then the data in the target data table may be updated according to the update data, in other words, the data in the target data table may be modified according to the update data, so that the data in the target data table meets the requirement of the preset storage structure information. For example, the actual padding value at the data missing position may be modified to a preset padding value or the like, but is not limited thereto.
Further, whether the financial data in the target data table meets the requirement of the preset storage structure information may be judged again, if yes, step S203 may be executed, otherwise, the judged result of the second judgment may be sent to the user terminal, so that the user terminal revises the data of the target data table again. In other words, in the solution of the embodiment of the present invention, it may be determined whether the data in the target data table meets the requirement of the preset storage structure information multiple times, until the data in the target data table meets the requirement of the preset storage structure information, and then step S203 is executed.
In a specific example, after the identification request is obtained, a plurality of data tables in the target database may be read from the target database, and whether the storage structure information of each data table meets the requirement of the preset storage structure information is determined according to the preset storage structure information of the data table, and if not, the determination result of the data table is sent to the user terminal, so that the user terminal performs modification. If the storage structure information of each data table meets the requirement of the preset storage structure information, the rule description file can be obtained, and step S203 is executed according to the rule description file. The specific content for determining whether the storage structure information of each data table meets the requirement of the preset storage structure information of the data table may refer to the above related content of the storage structure information of the determination target data table, and is not described herein again.
In another specific example, the rule description file may further include identification information of an associated data table of the target data table, where the associated data table is a data table in which data having an association relationship with the data to be identified is located. For example, the target data table is a transaction data table, and the associated data table may be an account information table, etc., but is not limited thereto. And preset storage structure information of the associated data table can be acquired and recorded as associated preset storage structure information, then whether the data in the associated data table meets the associated preset storage structure information or not can be judged, and the data in the associated data table is corrected according to the judgment result until the data in the associated data table meets the associated preset storage structure information. More contents about associating the preset storage structure information and determining whether the data in the associated data table satisfies the associated preset storage structure information may refer to the above description about determining whether the data in the target data table satisfies the preset storage structure information, and are not described herein again.
With continued reference to fig. 2, in a specific implementation of step S203, the data in the target data table may be subjected to exception identification according to the method description statement.
In a first specific example, the method description statement may include a first key field, and a plurality of data belonging to the first key field in the target data table may be determined and may be denoted as a plurality of first key data. Further, whether a plurality of first key data exist in the associated data table or not can be judged, if not, the first key data which do not exist in the associated data table can be used as abnormal data, and the position of the first key data which do not exist in the associated data table in the target data table can be used as a part of the identification result. For example, the target data table is a transaction data table, the first key field is account identifiers of both transaction parties, the plurality of first key data are account identifiers of both transaction parties in each transaction data, the associated data table is an account information table, whether the account identifier of each transaction data can be found in the account information table can be judged, and if not, the account identifier which cannot be found in the account information table can be used as abnormal data.
In a second specific example, the method description statement may further include a second key field, and it may be determined whether there is data missing in the data belonging to the second key field in the target data table. Specifically, it may be determined that a preset padding value is searched for in each financial data in a column corresponding to the second key field in the target data table, and a position of the preset padding value is used as a position of the abnormal data in the target data table. The first key field and the second key field may be the same or different, and the embodiment of the present invention does not limit this. For example, the target data table is a transaction data table, the second key field is account identifiers of both parties of the transaction, and it can be determined in the transaction data table whether data are missing in a column corresponding to the account identifiers of both parties of the transaction, that is, whether the account identifiers in each piece of transaction data are missing is determined, and if so, the missing part can be used as a position of abnormal data in the target data table.
In a third specific example, the method description statement may further include a uniqueness field, and it may be determined whether there is a duplication of the financial data belonging to the uniqueness field in the target data table. For example, if the target data table is an account information table and the unique field is an account identifier, it may be determined whether multiple account identifiers exist in the multiple account identifiers in the account information table, and if so, the multiple account identifiers may be used as the abnormal data. For another example, the target data table is a transaction data table, and the unique field may include transaction time and account information of the transaction party, so that it may be determined whether there is transaction data in each transaction data in the transaction data table, where the transaction time is the same and the account information of the transaction party is the same, and if so, the transaction data in the transaction time is the same and the account information of the transaction party is the same, which may be used as abnormal data.
In a fourth specific example, the method description statement may further include an identifier type and an identifier statement, where the identifier type and the identifier statement are in one-to-one correspondence, and each identifier statement is used to describe a standard format of data of the corresponding identifier type. Further, the identity type to which the identity data in the target data table belongs can be determined, whether the identity data is consistent with the standard format required by the identity type is judged according to the identity statement, and if not, the identity data which is inconsistent with the standard format can be used as abnormal data.
In a fifth specific example, the target data table is a transaction data table, the transaction data table includes a plurality of transaction records, the association data table is an account information table, and the transaction time of each transaction record and the account information of the transaction party can be determined; further, the account creation time of the transaction party may be looked up in the account information table, and it is determined whether the account creation time is after the transaction time, and if so, the transaction record is taken as the abnormal data.
Further, the identification result can be sent to the user terminal, and since the identification result includes the position of the abnormal data in the target data table, the user can correct the abnormal data according to the identification result, so that the financial data in the target data table meets the requirement of the method description statement.
