It should be noted that, the information data related to the user in the present specification is obtained and used on the premise that the user knows and agrees, and the obtaining, storing, using, processing, etc. of the information data all conform to relevant regulations of national laws and regulations.
Referring to fig. 1, an embodiment of the present disclosure provides a method for determining an abnormal object. The method is particularly applied to the server side. In particular implementations, the method may include the following:
S101: obtaining an object identifier of a target object; according to the object identification of the target object, collecting the associated data of the target object and the associated data of the relation object with a preset relation with the target object through multiple channels;
s102: according to a preset abnormal recognition rule, carrying out data matching on the associated data of the target object and the associated data of the relation object to obtain a target matching result aiming at the target object;
s103: determining whether the target object is abnormal according to the target matching result;
s104: under the condition that the target object is determined to be not abnormal, processing the associated data of the target object and the associated data of the relation object by using a preset abnormal risk identification model to obtain a target identification result aiming at the target object;

s106: and under the condition that the abnormal risk exists in the target object, adding the object identification of the target object into an abnormal risk tracking list to track the abnormal risk of the target object.
The target object may be specifically understood as an employee object of a mechanism or platform to be detected whether an abnormality exists. Such as a teller of a bank, or a trader of a stock exchange, etc. Of course, the above-listed objects are only illustrative when needed. In specific implementation, the target object may further include other types of physical objects or virtual objects according to specific application scenarios and processing requirements. The present specification is not limited to this.
Based on the embodiment, comprehensive and rich associated data including the associated data of the target object and the associated data of the associated object of the target object, which are related to the target object, can be acquired automatically; and furthermore, based on a preset abnormality recognition rule and preset abnormality risk recognition, the related data is utilized to carry out multiple detection recognition, so that whether the target object is abnormal or not and the abnormality risk are accurately and efficiently judged, the detection precision can be effectively improved, the detection error is reduced, and the situations such as omission and the like are avoided.
In some embodiments, the method of determining an anomalous object described above may be particularly applicable to the server side of an institution or platform involved in a transaction. Specifically, reference may be made to fig. 2.
The server may specifically include a background server applied to a supervision system side of a related institution or platform (for example, XX bank) related to transactions, and capable of implementing functions such as data transmission and data processing. Specifically, the server may be, for example, an electronic device having data operation, storage function and network interaction function. Alternatively, the server may be a software program running in the electronic device that provides support for data processing, storage, and network interactions. In the present embodiment, the number of servers is not particularly limited. The server may be one server, several servers, or a server cluster formed by several servers.
In specific implementation, as shown in fig. 2, the server may acquire, at regular intervals (for example, a week) according to a preset detection rule, association data of the target object and association data of a relationship object having a preset relationship with the target object by multi-channel acquisition according to the identification of the target object, so as to obtain richer and comprehensive association data related to the target object.
Then, based on a preset abnormality rule, the correlation data is utilized to perform first re-detection identification through data matching so as to determine whether the target object has an abnormality. When the abnormality of the target object is determined, the existing behavior of the target object can be directly determined to have definitely not returned to the staff rule requirement, and the violation condition exists, and then the related prompt about the target object can be directly sent to the terminal equipment held by the supervision object (for example, the supervisor of the target object and the like) of the target object so as to prompt the supervision object to timely process.
The terminal equipment specifically comprises a front end which is applied to one side of a target object and a supervision object and can realize functions of data acquisition, data transmission and the like. Specifically, the terminal device may be, for example, an electronic device such as a desktop computer, a tablet computer, a notebook computer, or a smart phone. Alternatively, the terminal device may be a software application capable of running in the above-mentioned electronic device. For example, it may be an employee APP of a transaction platform running on a smart phone, etc.
When the target object is determined to have no abnormality through the first re-detection recognition, the correlation data can be processed by using a preset abnormality risk recognition model to perform the second re-detection recognition so as to determine whether the target object has potential abnormality risk.
Under the condition that the abnormal risk exists in the target object, the object identification of the target object can be further added into an abnormal risk tracking list, so that continuous abnormal risk tracking can be carried out on the target object according to a preset tracking rule.
Therefore, the specific abnormal objects and the risk objects with potential abnormal risks can be accurately and comprehensively detected and identified, continuous abnormal risk tracking is carried out on the risk objects, omission is avoided, and a mechanism or a platform is better protected.
In some embodiments, referring to fig. 3, before the multi-channel collection of the associated data of the target object, the method may further include the following when implemented:
s1: generating an acquisition request of associated data about a target object; the acquisition request is sent to terminal equipment of the target object; the terminal equipment displays the acquisition request to a target object;
S2: detecting whether acknowledgement information of the terminal equipment for the acquisition request is received in a second time period or not; wherein, the confirmation information at least carries the identity signature of the target object;
s3: verifying the identity signature of the target object under the condition that confirmation information of the terminal equipment for the acquisition request is received in a second time period;
s4: and under the condition that the identity signature verification of the target object is confirmed to pass, the associated data of the target object are collected through multiple channels.
Based on the embodiment, the server can acquire the associated data of the target object in multiple channels on the premise that the target object knows and agrees with the authorization, so that corresponding data processing can be completed on the premise of protecting the data privacy of the target object.
In some embodiments, the association data of the target object may further include: the target object is based on equipment operation records of the terminal, self evaluation of the target object, targeted object quarantine messages or mails and the like in a first time period.
In some embodiments, the terminal device may present the acquisition request to the target object after receiving the acquisition request. According to the acquisition request, the target object can feed back the confirmation information aiming at the acquisition request to the server through the terminal equipment under the condition of knowing and agreeing to acquire the associated data. The confirmation information may specifically also carry an identity signature that is known only to the target object.
Specifically, the identity signature is generated by using a user private key held by the target object, a user-defined password of the target object and a random number based on a corresponding encryption algorithm. For the server, the authenticity of the identity signature can be verified, but the identity signature cannot be generated by self.
After receiving the confirmation information, the server can conduct true and false verification on the identity signature, when the identity signature is judged to be true, the server can determine that the identity signature passes verification, the target object knows and agrees to collect relevant associated data, and at the moment, the server can collect relevant data relevant to the target object in multiple channels.
In some embodiments, the above-mentioned multi-channel collection of the associated data of the target object according to the object identifier of the target object may include the following when implemented:
inquiring an information database of the target object according to the object identification of the target object to determine the equipment identification of the terminal equipment of the target object, the employee number of the target object and the attribute information of the target object;
inquiring an employee management system according to the employee number of the target object, and acquiring working behavior data in a first time period of the target object as the associated data;
And/or the number of the groups of groups,
inquiring a login record of the terminal equipment according to the equipment identification of the terminal equipment of the target object so as to determine the account identification of the virtual account of the target object; according to the virtual account identification, searching operation records of the key websites and/or the key media, and obtaining online behavior data of the target object in a first time period as the associated data;
and/or the number of the groups of groups,
generating a questionnaire aiming at the target object according to the attribute information of the target object; and transmitting the questionnaire to a target object to acquire response data of the target object for the questionnaire as the association data.
The working behavior data may specifically include at least one of the following: the working time length, the delay times, the early-return times, the performance, the attendance rate and the like.
The attribute information of the target object may specifically include basic information of the target object, for example, sex, age, blood type, etc. of the target object; in addition, the attribute information of the target object may further include working information of the target object, for example, a service department where the target object is located, a job level of the target object, a working year of the target object, and the like.
Based on the embodiment, the server can acquire the relative data of the target object which is rich and comprehensive and is directly related to the target object through multiple channels.
In some embodiments, the terminal device may be a main operation device used by the target object, and the device identifier of the terminal device may be a device fingerprint of the terminal device, for example, a mac address, a device serial number (IMEI), an SSID, an IMSI, and the like.
The online behavior data may specifically include: the target object is based on a web transaction record, web browsing record, web rating record, web chat record, etc. of the key website and/or key medium. The key website may be a website related to trade, for example, a stock website, a futures trade website, a website of other trade platforms, and the like. The key medium can be commonly used chat interaction software.
When the server specifically acquires online behavior data of the target object in a first time period, a collaboration request can be initiated to terminal equipment of the target object; the collaboration request may carry an identity signature carried by acknowledgement information provided before the target object. After receiving the collaboration request, the terminal equipment can verify the authenticity of the identity signature a priori, and under the condition that the identity signature passes verification, the investigation authority about the terminal equipment is opened to the server; meanwhile, the terminal equipment also sends prompt information about developing the investigation permission to the target object. After the target object views the prompt information, if the temporary decision prohibits the server from acquiring the online behavior data through the terminal equipment, the terminal equipment can be operated to send out a rejection instruction. Correspondingly, the terminal equipment can timely terminal the investigation authority of the server.
After obtaining the investigation authority, the server can search and inquire the login record of the target object based on the terminal device by virtue of the investigation authority; and obtaining the account identification of the virtual account of the target object according to the login record. The virtual account may specifically be a virtual account used when the target object logs in to the key website and/or the key medium. For example, the account identifier of the virtual account may be an account name used when the target object logs into a stock website to perform a stock exchange operation.
Then, the server can search the operation record of the key website and/or the key medium of the target object in the terminal equipment according to the account identification of the virtual account so as to obtain the online behavior data of the target object in the first time period.
Further, the server can also detect whether the target object uses other operation terminals besides the terminal equipment according to the operation records of the key websites and/or the key media of the target object in the terminal equipment; when the target object is determined to be used by other operation terminals, the online behavior data in a first time period which is richer and more comprehensive for the target object can be obtained by accessing and searching the other operation terminals on the premise that the target object is known and agrees in the mode.
In some embodiments, during implementation, the server may screen out a questionnaire matched with the target object from a preset questionnaire library according to attribute information of the target object; and then the questionnaire is sent to the terminal equipment held by the target object. After receiving the questionnaire, the terminal device can display the questionnaire to the target object and remind the target object of replying in time. The target object can complete the reply of the questionnaire through the terminal device. Correspondingly, the terminal equipment collects reply data of the target object aiming at the questionnaire and feeds the reply data back to the server.
After receiving the reply data, the server can directly take the reply data as associated data; the answer data can also be processed by using a preset semantic recognition model to obtain a corresponding answer semantic text, and then the answer semantic text is used as associated data.
In some embodiments, the preset relationship may specifically include one or more of the following: relatives, friends, colleagues, net friends, etc. Accordingly, the relationship object of the target object may specifically include: relatives, friends, colleagues, net friends, etc. of the target object.
In some embodiments, in implementation, the relationship object having a preset relationship with the target object may be determined according to the following manner:
inquiring an information database of the target object according to the object identification of the target object to determine attribute information of the target object; inquiring the staff management system according to the attribute information of the target object to determine a relation object with a working relation with the target object;
and/or the number of the groups of groups,
determining terminal equipment used by the target object according to the object identification of the target object; inquiring the interaction record of the terminal equipment to determine a relation object with an interaction relation with the target object in a first time period;
and/or the number of the groups of groups,
and according to the object identification of the target object, inquiring an information database of the target object to determine a relation object which has a relative relation with the target object.
Based on the embodiment, the server can accurately and comprehensively determine the relation object with the preset relation with the target object, and acquire the relation data of the relation object indirectly related to the target object through multi-channel acquisition by referring to the mode of acquiring the relation data of the target object.
In some embodiments, the association data of the relationship object may specifically include at least one of: occupation of the relationship object, business management information related to the relationship object, court execution information related to the relationship object, and the like.
In some embodiments, in implementation, the server may acquire and automatically acquire, according to the keywords, the processing rules and the like of the supervision object, the institution or the platform custom configuration, the association data of the target object and the association data of the relationship object of the target object through an RPA (Robotic Process Automation robot flow automation) technology.
In some embodiments, the performing data matching on the association data of the target object and the association data of the relationship object according to the preset anomaly identification rule to obtain a target matching result for the target object may include:
s1: determining abnormal matching degree of each associated data according to a preset abnormal recognition rule, associated data of a target object and associated data of a relation object; the preset abnormality identification rule comprises reference values of a plurality of key associated data;
s2: and obtaining a matching result aiming at the target object through weighting operation according to the abnormal matching degree of each associated data.
Based on the above embodiment, the first re-detection recognition can be performed by using the preset anomaly recognition rule, the associated data of the target object, and the associated data of the relationship object, so as to obtain the target matching result with better accuracy, wider coverage dimension and higher reference value.
In some embodiments, the preset anomaly identification rule may specifically be obtained by clustering association data of a large number of historical anomaly objects and association data of relationship objects of the anomaly objects in advance.
Specifically, the preset abnormality recognition rule may include a reference value of associated data for indicating abnormality. The reference value may specifically be a key character or a parameter threshold.
Correspondingly, the implementation and implementation, performing data matching on the association data of the target object and the association data of the relation object according to the preset abnormality recognition rule may include: and carrying out key character matching or parameter threshold comparison on the associated data of the target object and the associated data of the relation object of the target object with the reference value of the associated data corresponding to the preset abnormality recognition rule respectively to obtain the abnormality matching degree of each associated data.
Then, the server can also obtain a matching result aiming at the target object through weighting operation by combining the abnormal matching degree of each associated data according to the preset weight coefficient.
Based on a preset weight coefficient, distinguishing the abnormal matching degree of the associated data directly related to the target object and the abnormal matching degree of the associated data indirectly related to the target object, and setting different weight values; and the relationship objects with different awareness degrees with the target object can be distinguished, and different weight values are set for the abnormal matching degree of the associated data of the different relationship objects. The preset weight coefficient may be specifically determined based on association data of the historical abnormal object and association data of the relationship object of the abnormal object by combining expert experience.
In some embodiments, after determining whether the target object has an anomaly according to the target matching result, referring to fig. 4, when the method is implemented, the method may further include the following:
s1: generating an abnormality prompt about the target object under the condition that the target object is determined to have abnormality according to the target matching result;
s2: determining a supervision object of the target object;
s3: sending an abnormal prompt about a target object to terminal equipment held by the supervision object; and pausing the critical rights of the target object.
In the implementation process, the server can determine the supervision object of the target object by querying the employee management system according to the working information of the target object.
In specific implementation, when it is determined that the target object has an anomaly according to the target matching result, it can be clearly determined that the existing behavior of the target object has violated the relevant employee's rule-keeping requirements, and that there has been a significant offending anomaly (e.g., preserving personal client information, intentionally operating without a system flow, participating in illegal funding, credit card cash register, lending account, excessive guarantee, abnormal lending or investment, hidden manager, improper interaction with a provider, etc.). At this time, the server may send an exception prompt of the target object to a terminal device held by the supervision object, and prompt the supervision object to verify and process the exception behavior of the target object in time. Meanwhile, the server can also pause the key authority of the target object so as to avoid the target object from continuing to perform abnormal behaviors and further damaging the data security of the mechanism or the platform. The above-mentioned key authority can be understood as an operation processing authority related to the sensitive data.
Based on the above embodiment, after identifying the abnormal object with abnormal behavior, the server may process the abnormal object in time, so as to avoid the data security of the related institution or platform related to the transaction from being damaged.
In some embodiments, when it is determined that the target object has no abnormality according to the target matching result, it can only be determined that the existing behavior of the target object in a first period of time has no abnormality, but it cannot be determined whether the target object has a potential abnormality risk. For example, the target object may not have an abnormal behavior implemented for one period of time, but may also be implemented for the next period of time in the future. Therefore, in order to more effectively and comprehensively protect the data security of the mechanism or the platform, after determining that the target object has no abnormality according to the target matching result, the association data of the target object and the association data of the relation object can be processed by using a preset abnormality risk recognition model, and the second detection recognition can be performed to further determine whether the target object has potential abnormality risk.
The preset abnormal risk recognition model is specifically obtained by training in advance, and can predict and output a neural network model aiming at an abnormal risk value of the target object based on the input association data of the target object and the association data of the relation object of the target object. Specifically, the preset abnormal risk identification model may include a model trained based on a support vector regression model.
In the implementation, the association data of the target object and the association data of the relation object can be combined according to a specified mode to obtain combined association data; and inputting the combined associated data into a preset abnormal risk identification model, and running the preset abnormal risk identification model. When the preset abnormal risk identification model specifically operates, a plurality of associated features with different dimensions can be extracted from the combined associated data, and then the associated features with different dimensions are subjected to multi-channel feature fusion to obtain the fused associated features; and further, according to the fused associated characteristics, the corresponding abnormal risk value can be calculated and output to serve as the target identification result.
Before implementation, referring to fig. 5, a preset abnormal risk identification model may be trained in the following manner:
s1: acquiring sample data; wherein the sample data at least comprises the association data of the sample object and the combination of the association data of the relation object of the sample object;
s2: labeling the sample data to obtain labeled sample data; constructing an initial model based on a support vector regression model;
S3: training the initial model by using the marked sample data to obtain a preset abnormal risk identification model meeting the requirements.
After the sample data is obtained, preprocessing such as data cleaning, data filtering and the like can be performed on the sample data so as to reduce data errors of the sample data and improve data precision.
When the sample data is specifically marked, a positive label can be added to the sample data mark corresponding to the abnormal sample object, and a negative label can be added to the sample data corresponding to the normal sample object, so that marked sample data is obtained.
In some embodiments, the determining whether the target object has an abnormal risk according to the target recognition result may include the following steps when in implementation:
s1: detecting whether a target identification result is larger than a preset risk threshold;
s2: and under the condition that the target identification result is larger than a preset risk threshold value, determining that the target object has abnormal risk.
Based on the above embodiment, whether the target object has an abnormal risk can be accurately determined by using the target recognition result obtained by the preset abnormal risk recognition model.
In some embodiments, after determining that the target object has an abnormal risk, the method may further include the following when implemented: combining the association data of the target object and the association data of the relation object with a preset relation with the target object to serve as a training sample of the current time period; the training samples in the current time period are used for training and updating a preset abnormal risk identification model after the current time period is ended, and the preset abnormal risk identification model applied to the next time period is obtained.
Based on the above embodiment, the preset abnormal risk recognition model can be continuously trained and updated by using the training sample in the current time period, so that the preset abnormal risk recognition model used in the next time period can be continuously improved and improved along with the change of the actual application situation, and therefore whether the target object has potential abnormal risk can be more accurately judged based on the preset abnormal risk recognition model.
In some embodiments, after adding the object identifier of the target object to the abnormal risk tracking list, referring to fig. 6, the method may further include the following when implemented:
s1: at intervals of a preset time period (for example, every day), inquiring a current abnormal risk tracking list, and determining a risk object to be subjected to abnormal risk tracking;
s2: acquiring association data updated currently by a risk object and association data updated currently by a relation object of the risk object;
s3: determining whether the risk object is abnormal or not according to a preset abnormality identification rule, association data of the current update of the risk object and association data of the current update of the relation object of the risk object;
S4: under the condition that the risk object is determined to be abnormal, processing the association data updated currently by the risk object and the association data updated currently by the relation object of the risk object by using a preset abnormal risk identification model, and determining whether the risk object is abnormal or not;
s5: adding a current risk detection result for the risk object in the abnormal risk tracking list under the condition that the risk object is determined to have no abnormal risk; the current risk detection result carries a time tag.
The preset time period is less than the first time period, for example, may be 1 day or 12 hours. The above-mentioned time tag may be used in particular to indicate the detection time.
Based on the above embodiment, the server may closely track the risk object in the abnormal risk tracking list at smaller time intervals for a preset time period, so as to more finely detect and determine whether the risk object is abnormal.
In some embodiments, in a case where it is determined that the risk object does not have an abnormal risk, the method may further include the following when implemented:
s1: inquiring and determining whether the accumulated safety duration of the risk object which is not present with abnormal risks continuously is larger than a preset safety duration threshold according to the risk detection result of the risk object in the abnormal risk tracking list;
S2: and under the condition that the accumulated safety time length of the risk object without abnormal risks continuously exists is larger than the preset safety time length threshold value, eliminating the risk object from the abnormal risk tracking list.
In the implementation, the accumulated safety duration of the risk object without abnormal risk is obtained through statistics by inquiring and according to the time tag of the risk detection result of the risk object recorded in the abnormal risk tracking list; comparing the accumulated safe duration with a preset safe duration threshold value; according to the comparison result, when the accumulated safety time length is determined to be greater than a preset safety time length threshold, the target object can be judged to have no abnormality, and meanwhile, no potential abnormal risk exists, so that the risk object can be removed from a risk tracking list, and the risk tracking of the object is not continued; in contrast, according to the comparison result, when the accumulated safety duration is less than or equal to the preset safety duration threshold, risk tracking can be continuously performed on the target object.
Based on the embodiment, the target object which does not have abnormality and potential abnormality risk can be timely determined and removed through continuous risk tracking, so that the data processing cost and the data processing consumption of the server side are effectively reduced.
In some embodiments, when it is determined that the target object has an abnormal risk, part of the key rights of the target object may be paused according to the attribute information of the target object. When the target object is detected to be removed from the risk tracking list, the server can restore part of key rights of the target object.
In some embodiments, after processing the association data currently updated by the risk object and the association data currently updated by the relationship object of the risk object by using the preset abnormal risk identification model, determining whether the risk object has an abnormal risk, the method may further include the following when implemented:
under the condition that the risk object is determined to have abnormal risk, adding a current risk detection result aiming at the risk object into the abnormal risk tracking list; the current risk detection result carries a time tag;
the method comprises the steps of,
inquiring and determining whether the accumulated risk duration of the current continuous abnormal risks of the risk object is greater than a preset risk duration threshold according to the risk detection result of the risk object in the abnormal risk tracking list;
and under the condition that the accumulated risk time length of the current continuous abnormal risks of the risk object is larger than the preset risk time length threshold value, determining that the abnormal risks exist in the risk object.
Based on the embodiment, the abnormal object can be accurately identified and determined from the risk objects through continuous risk tracking, so that the data security of related institutions or platforms can be better protected.
From the above, based on the method for determining an abnormal object provided in the embodiments of the present disclosure, the association data of the target object and the association data of the relationship object of the target object are obtained first; judging whether the target object is abnormal or not according to a preset abnormal recognition rule, the association data of the target object and the association data of the relation object; under the condition that the target object is determined to be abnormal, processing the association data of the target object and the association data of the relation object by utilizing a preset abnormal risk identification model to determine whether the target object is abnormal; and under the condition that the abnormal risk exists in the target object, adding the object identification of the target object into an abnormal risk tracking list so as to track the abnormal risk of the target object.
