Conjunction rule risk parameter, the first black and white lists and scene risk parameter, server is provided in index storehouse in advance to exist It after receiving air control request, is requested in response to the air control, is obtained from index storehouse and close rule risk parameter, the first black and white lists and field Scape risk parameter, to carry out risk control to given transaction, wherein given transaction refers to the transaction ID that air control request carries Corresponding transaction.
S203: risk parameter, first black and white lists and the scene risk parameter are advised according to the conjunction, to described Given transaction carries out risk control and obtains the air control result of the given transaction.
Specifically, server by air control request in the transaction related information that carries such as transaction amount, user identifier, trade company mark Know, advises risk parameter such as channel single limit, channel when Day Sum Limited, trade company put list etc. on record and matched, to realize with closing Risk control is carried out to given transaction based on rule risk parameter is closed;By the corresponding user account information of user identifier and merchant identification The conjunction rule user's merchant information and offending user merchant information recorded in corresponding merchant account information and the first black and white lists into Row compares, and judges whether user and trade company belong to the user trade company of the first black and white lists record, to realize black based on first White list carries out risk control to given transaction;Server also determines that the channel response timeliness of trading channel and channel are traded successfully Rate etc. determines that the odd-numbered day blocks with card limit, together with amount of money stroke count, Sorry, your ticket has not enough value with card for the corresponding trade company of above-mentioned merchant identification Stroke count etc. carries out risk control to given transaction based on scene risk parameter to realize.Risk based on above three dimension Control, obtains the air control result of given transaction.Further, server can also return to air control result to terminal to notify to use Family, to improve user experience.
In practical application, in order to improve air control efficiency, server can be carried out given transaction according to pre-set priority Risk control.Specifically, server can advise risk parameter, the first black and white lists and scene risk parameter three according to closing Priority orders successively carry out risk control to the given transaction and obtain the air control result of the given transaction;Wherein, into In row risk control treatment process, if current risk control result is air control failure, it is determined that the risk knot of the given transaction Fruit is air control failure, if current risk control result passes through for air control, then successively based on next parameter to the specified friendship Easily carry out risk control processing, until all parameter traversals finish, the air control result that last time risk control is handled as The air control result of the given transaction.Below to now process is described in detail in fact.
Server according to rule risk parameter is closed to given transaction progress air control control, obtains the first air control as a result, working as first When first air control result is that air control fails, then characterization is air control failure for the air control result of the given transaction, it may not be necessary into The subsequent air control operation of row, directly using the first air control result as the air control result of the given transaction;When the first air control result is When air control passes through, server carries out risk control to the given transaction according to first black and white lists and obtains the second air control knot Fruit;When the second air control result is that air control fails, then characterization is air control failure for the air control result of the given transaction, can Subsequent air control operation need not be carried out, directly using the second air control result as the air control result of the given transaction;Work as institute When stating the second air control result and passing through for air control, according to the scene risk parameter, risk control is carried out to the given transaction and is obtained To third air control as a result, using the three air controls part result as the air control result of the given transaction.
Wherein, scene risk parameter may include multiple parameters, such as channel transaction success rate, channel response timeliness channel Mass parameter and odd-numbered day with card limit, with card with amount of money stroke count, with card Sorry, your ticket has not enough value the transaction flows parameter such as stroke count, in base In scene risk parameter to given transaction carry out risk control when, equally can according in scene risk parameter each parameter it is preferential Grade sequence, successively carries out risk control to the given transaction, if current risk control result is air control failure, it is determined that be based on The scene risk parameter carries out the air control result of risk control for air control failure, if current risk controls to the given transaction As a result pass through for risk, then risk control processing is successively carried out to the given transaction based on next parameter again, until all Parameter traversals finish, the result that last time risk control is handled as based on the scene risk parameter to the specified friendship Easily carry out the air control result of risk control.
In some possible implementations, if being carried out based on channel quality parameter to the corresponding first passage of given transaction When the result of risk control is that air control fails, server can also carry out channel switching for given transaction, by the specified friendship Second channel is easily switched to, and risk control is carried out to the second channel based on the channel quality parameter, to ensure transaction Reliability, continuity.If being appreciated that, server is based on channel quality parameter all channels corresponding to given transaction and carries out The result of risk control is air control failure, then characterization is air control failure for the air control result of the given transaction, and server can Subsequent risk control need not be carried out.
It should be noted that above-described embodiment is to be illustrated using the parameter of three dimensions as example, in the application In other possible implementations of embodiment, the parameter that may be incorporated into other dimensions carries out risk control, further enhances wind Control the reliability of result.Also, in practical application, the sequence of each parameter can also be adjusted according to actual needs, this reality It applies example and this is not construed as limiting.
From the foregoing, it will be observed that the embodiment of the present application provides a kind of transaction risk control method, this method is carried out from multiple dimensions Systematically risk control specifically after receiving the air control request for carrying out risk control to given transaction, is obtained from index storehouse Take conjunction rule risk parameter, the first black and white lists and scene risk parameter, wherein closing rule risk parameter includes that rule parameter is closed in channel Rule parameter is closed with channel, closing rule parameter based on channel can determine whether trading channel meets operation regulation, close rule based on channel Parameter can determine whether trade company meets operation regulation, and scene risk parameter includes channel quality parameter and transaction flow parameter, It can determine whether channel quality meets operation regulation based on the channel quality parameter, can be determined based on the transaction flow parameter Whether transaction meets transaction scene operation regulation, namely other than black and white lists carry out risk control, and this method also passes through conjunction rule From multiple dimensions to given transaction with carrying out fine granularity risk control, air control result can for risk parameter, scene risk parameter etc. It is higher by property, it being capable of effective helpdesk, businessman and user's reasonably avoiding payment risk.
It is appreciated that embodiment illustrated in fig. 2 is planned mainly by regular subdivision from linear angles similar to pyramid structure Control scene point danger one by one, to realize transaction risk control.In some cases, server is also based on historical trading letter Breath establishes Analysis model of network behaviors, realizes global risk control by Analysis model of network behaviors, ensures the safety and stability of transaction.
Next, in conjunction with Fig. 3 to another implementation of transaction risk control method provided by the embodiments of the present application into Row explanation, referring to Fig. 3, this method comprises:
S301: historical transactional information is obtained.
Historical transactional information may include being related to the relevant historical transactional information of user and the specified friendship to the given transaction Easily it is related to the relevant historical transactional information of trade company and is related to the relevant historical transactional information of platform to the given transaction.
Wherein, the relevant historical transactional information of user is related to the given transaction can specifically include trade network interconnection association Discuss the address (Internet Protocol, IP), trading frequency, transaction amount (including transaction amount mean value, maximum value, minimum value Deng) and type of transaction, consumption scene etc. at least one of, based on this can identify bank card usurp, credit card arbitrage wind Danger.
Being related to the relevant historical transactional information of trade company to the given transaction can specifically include: type of transaction, payment-reimbursement Matching degree, payment-cancellation matching degree, payment transaction IP address statistical probability etc. are based on this, can identify the brush uniline of trade company For, lower single act of malice etc..
To the given transaction be related to the relevant historical transactional information of platform then can be used for identifying internal staff's violation operation, The risks such as permission bypasses, repeat business.
S302: Analysis model of network behaviors is determined according to the historical transactional information.
The Analysis model of network behaviors, which is used to assess given transaction, whether there is the abnormal behaviour wind of trade company, user or platform Danger.In specific implementation, server can be acquired from the historical transactional information trade company's behavioral data, user behavior data with And platform behavioral data, specifically, server can be related to acquiring in the relevant historical transactional information of user to given transaction Then, trade company's Analysis model of network behaviors is determined according to trade company's behavioral data, user's row is determined according to the user behavior data For analysis model, and, platform Analysis model of network behaviors is determined according to the platform behavioral data.
Specifically, server can formulate corresponding behavior according to different transaction scenes, different risk loopholes respectively Analysis model.By taking trade company's brush single game scape as an example, mostly in merchant end, regular place an order of merchant end pays and has general brush single game scape The factors such as reimbursement, cancellation and the exchange hour span of rule may be incorporated for fitting Analysis model of network behaviors, to identify quotient Family whether there is brush single act.
S303: air control request is received.
S304: it is obtained from index storehouse and closes rule risk parameter, the first black and white lists and scene risk parameter.According to the conjunction Advise risk parameter, first black and white lists and the scene risk parameter.
Wherein, the specific implementation of S303 and S304 may refer to the description of embodiment related content described in Fig. 2, no longer superfluous herein It states.It, can be in subsequent execution risk control operation it should be noted that after determining Analysis model of network behaviors by S301 and S302 Directly using the model without redefining model, namely when executing S303 and S304, if Analysis model of network behaviors is existing, It then can directly utilize existing model.
S305: risk parameter, first black and white lists, the scene risk parameter and the row are advised according to the conjunction Risk control is carried out to the given transaction for analysis model and obtains the air control result of the given transaction.
Specifically, server advises risk parameter, first black and white lists and the scene risk parameter according to the conjunction Risk control is carried out to given transaction, and risk control is carried out to the given transaction according to Analysis model of network behaviors, according to base In the air control for the air control result and Behavior-based control analysis model for closing rule risk parameter, the first black and white lists and scene risk parameter As a result final air control result is obtained.
From the foregoing, it will be observed that carrying out risk control the process employs rule subdivision and Analysis model of network behaviors two ways obtains wind Control is as a result, specifically, carrying out high abstraction to the Risk characteristics of operation system, commenting from internal risks state modulator, internal act The multi-angular analysis such as survey, external administration policy form full-range Risk Control System, utilize the skills such as multiple rule, data fitting Art means are finely divided transaction risk, the scientific quantification for realizing risk control and precisely anticipation, reliability with higher.
It is appreciated that transaction risk control method provided by the embodiments of the present application is the various risks ginseng relied in index storehouse What number was realized.However, the risk parameter in index storehouse is not unalterable, such as closes rule parameter for channel, industry is legal Policy may be changed with industry development namely reference channel conjunction rule parameter can be with the change of the legal policy of industry And change, likewise, platform transaction business demand can also according to the actual situation and change namely accessory channel close Rule parameter is changed with platform transaction business demand.Based on this, server can also be to the risk parameter etc. in index storehouse It is updated.
Specifically, server can receive operation system transmission index allocation parameter, the index allocation parameter include to At least one of conjunction rule risk parameter, the first black and white lists to be updated and scene risk parameter to be updated of update, Then server updates corresponding parameter in the index storehouse according to the index allocation parameter.By updating the phase in index storehouse Parameter is closed, the timely adaption demand variation of the transaction risk control method can be made, the updated parameter of server by utilizing carries out Risk control can ensure the reliability of air control result, so that effectively helpdesk, businessman and user's reasonably avoiding pay wind Danger.
In the present embodiment, by the way that the user and quotient that the first black and white lists are recorded can be filtered using the first black and white lists Risk control is realized at family, but in practical applications, and the user of the first black and white lists record and trade company are often that unlawful practice reaches The user of certain number and trade company, for there are unlawful practice but unlawful practice number is not up to user and the trade company of preset value, Also referred to as there is user and the trade company of potential threat, and be not recorded in the first black and white lists, by the first black and white lists without Method filters user and the trade company of these potential threats, therefore, server can also be safeguarded in index storehouse the second black and white lists ( Claim lag black and white lists), record has that there are the user of potential threat and trade companies in the second black and white lists, in this way, black by second White list can filter the reliability that air control result is further increased there are the user of potential threat and trade company.
The implementation for carrying out risk control based on the second black and white lists is described in detail below.Specifically, if institute It states user that given transaction is related to or trade company is marked in second black and white lists, determine that the given transaction is potential prestige Side of body transaction;It trades, is counted with card with trading number and/or transaction amount, if described with card for the potential threat When being more than corresponding threshold value with trading number or transaction amount, it is determined that the air control result of the given transaction is air control Failure.
In order to enable the technical solution of the application is clearer, below in conjunction with concrete application scene to the embodiment of the present application The transaction risk control method of offer is introduced.
The application scenarios schematic diagram of transaction risk control method shown in Figure 4, include in the application scenarios terminal 10, Server 20 and index storehouse 30, in index storehouse 30 configured with close rule risk parameter, the first black and white lists, the second black and white lists with And scene risk parameter, wherein closing rule risk parameter includes channel single limit, channel when Day Sum Limited, the accumulative of that month limit in channel Volume, the limitation of channel same day stroke count and trade company put list, crucial trade company qualifications on record, and the first black and white lists record, which has, closes rule User's merchant information of user's merchant information and violation, the second black and white lists record have there are the user of potential threat and trade company, Scene risk parameter include channel transaction success rate, channel response timeliness, the odd-numbered day with card limit, with card with amount of money stroke count and with card Sorry, your ticket has not enough value stroke count etc..
Above-mentioned parameter is the risk problem prompted according to operation system, for example transaction success rate is low, generation identity theft is thrown Tell, that single phenomenon is brushed by trade company is serious, disassemble business risk process, from close rule, scene feature angularly analysis process risk and determine , specifically, for above-mentioned risk problem, risks and assumptions are extracted, such as channel odd-numbered day limit, single limit, the black and white of card user List, same card are with amount of money stroke count, payment frequency, payment-reimbursement matching degree, trading environment (IP address occurs for transaction) etc., then According to transaction scene classification, and the independent factor is extracted respectively and is configured in index storehouse.
Also, server 20 obtains historical transactional information, and trade company's behavioral data is acquired from the historical transactional information, is used Family behavioral data and platform behavioral data;Trade company's Analysis model of network behaviors is determined according to trade company's behavioral data, according to described User behavior data determines user behavior analysis model, and, platform behavioural analysis mould is determined according to the platform behavioral data Type.
In order to make it easy to understand, being illustrated by taking trade company's brush single act analysis model as an example.Fig. 5 is referred to, Fig. 5 is based on quotient Trade company's brush single act that reimbursement information, the information that Cancels Transaction, payment transaction IP address information in the historical transactional information of family are established Analysis model.Wherein, R indicates the matching degree of Zhi Fuyu reimbursement transaction, and C indicates the matching degree that Zhi Fuyu Cancels Transaction, and I indicates branch Transaction IP address statistical probability is paid, G indicates the gravity factor, shows for majorized function value, and D indicates that model calculates score value, and D value is got over Height then shows that transaction belongs to that the single probability of brush is higher, and risk is bigger, and R, C, I are indicated with hundred-mark system, and G value is typically in the range of 1 to 10 Between.Specifically, which can be characterized by following formula:
Wherein, the meaning of formula (1) R, C, I, G and D is identical as R, C, I, G, D meaning in Fig. 5, specifically refers to correlation above Content description, e is natural constant.
In distribu-tion index library 30 and after establishing Analysis model of network behaviors, server 20 can use risk parameter and behavior point It analyses model and carries out risk control.Specifically, it when user initiates transaction by terminal 10, generates air control and requests, in air control request Carry the information such as transaction ID, user identifier, merchant identification, platform identification, transaction amount and trading channel, server 20 Air control request is received, risk is on the one hand carried out to the corresponding given transaction of transaction ID according to the risk parameter in index storehouse Control, another aspect Behavior-based control analysis model carry out risk control to given transaction.
Specifically, risk control is carried out according to the risk parameter in index storehouse to specifically include, transaction amount and channel is single Limit compares, and day trade transaction volume determines the accumulative friendship of the transaction and this month complete transaction compared with the same day limit of channel Whether easy volume, which is more than that channel is accumulative, is worked as whether Monthly Sum Limit and the transaction are more than the limitation of channel same day stroke count, then, then determines quotient Whether mark corresponding trade company in family, which is recorded in trade company, is put on record in list, if has crucial trade company qualifications, if transaction amount It is less than channel single limit, day trade transaction volume is less than channel and works as Day Sum Limited, and the transaction and this month complete transaction is tired Meter turnover is less than channel and adds up to work as Monthly Sum Limit, which is also less than the limitation of channel same day stroke count, also, merchant identification pair The trade company answered is recorded in trade company and puts on record in list, and has crucial trade company qualifications, then air control passes through, and can continue through Black and white lists are screened.
