Embodiment one
Fig. 1 is a kind of schematic flow sheet of account number Risk Identification Method that the embodiment of the present invention one is provided.The present embodiment
Method can be performed by account number risk identification device, and wherein the device can be realized by software and/or hardware.As shown in figure 1, this reality
The account number Risk Identification Method for applying example offer specifically includes following steps:
Step 110, the behavioral data for obtaining target account number, the behavioral data include current login or access target account number
Facility information, IP address and login or access number of attempt.
Wherein, target account number is that, for a certain application program or a certain webpage, background server can be monitored
Complete the account number of user's registration, such as QQ account numbers, WeChat accounts, forum's account number and shopping website account number etc..
When background server monitors target account number in logged or access, got automatically login or accessed the mesh
The facility information (such as device number) of the terminal unit of mark account number.As same target account number can be logged in different equipment, therefore,
Facility information can be used as the foundation of account number risk identification.
Exemplary, when target account number is in logged or access, background server can also get target account number institute
In the IP address (Internet Protocol Address, internet protocol address) of terminal.As the IP address for passing through terminal can
The corresponding geographical position of terminal is obtained from IP geographic position datas storehouse, therefore acquired geographical location information can be used as current
Geographical location information when target account number is logged or accesses.Therefore, target account number can be detected by IP address whether to exist
Conventional geographical position is logged or accesses.
Exemplary, in preset time range, target account number is logged in or the number of attempt of access exceeds what is pre-set
Number of times, or, the number of attempt for logging in or accessing the target account number in a certain equipment or a certain IP address exceeds what is pre-set
During number of times, background server can be by the device number logon attempt of target account number or current IP address or current device or access
Activity recognition is a kind of risk behavior.Therefore log in or access number of attempt can also as account number risk identification it is main according to
According to.
Step 120, by behavioral data respectively with the historical behavior data of target account number and default abnormal operation recognition strategy
Matched.
Wherein, the historical behavior data of target account number mainly include target account number after by user's registration, User logs in or
The common equipment information and conventional IP address of access target account number.The acquisition modes of above-mentioned historical behavior data can be:Afterwards
Platform server is determined in preset time period after the facility information or IP address of statistics login or access target account number.
Wherein, preset time period can be configured in advance, for example, be preferably 6 months.It is exemplary, preset time period also dependent on
The concrete facilities real-time update at family.
Wherein, default abnormal operation may include:Target account number initiates the number of attempt for logging in or accessing in Preset Time
More than preset times threshold value, or, same equipment or same IP address in Preset Time are initiated to log in or access the target
The number of attempt of account number exceedes preset times threshold value.Wherein, preset times threshold value is in difference by a large amount of difference account numbers of statistics
In the case of operation and the empirical value that draws.It is generally preferred to initiate per hour to log in or the number of times of access request is 15 times.
It is exemplary, by behavioral data respectively with the historical behavior data of target account number and default abnormal operation recognition strategy
Matched, main including but not limited to following three kinds of situations:
1st, the facility information historical device information corresponding with target account number of current login or access target account number is carried out
Matching;For example, if the facility information of current login or access target account number is corresponding with by target account number determined by statistics
When historical device information is differed, can primarily determine that current goal account number there may be certain risk;
2nd, the IP address history IP address corresponding with target account number of current login or access target account number is matched;
Specifically, when lawless person can be logged in or be accessed to target account number by Agent IP, IP address now may be with target
The corresponding history IP address of account number is different.Therefore, current goal account number there may be certain risk;
3rd, will log in or access number of attempt and matched with preset times threshold value.Exemplary, specific embodiment can
Including as follows:If the number of times that target account number initiates logging request in Preset Time exceedes preset times threshold value, this is can be shown that
There is certain risk in account number;Same equipment can be logged in the Preset Time or access target account number number of attempt with it is pre-
If frequency threshold value compares, if exceeding preset times threshold value, can illustrate that current device may be used by lawless person, enter
And can also illustrate that current device will be logged in or the target account number that accesses there is also certain risk;Can also be by same IP address
Log in the Preset Time or access target account number number of attempt with preset times threshold value compared with, if more than preset times threshold
Value, then can illustrate that current IP address has certain risk, and then can also illustrate to initiate to log in or access under current IP address to ask
The target account number asked there is also certain risk.
For first two situation, from user perspective, using white list strategy, account number normal behaviour is acquired,
The custom of real user and behavior are to be difficult to be imitated by mechanization batch.The attacker in storehouse is hit even with a large amount of Agent IPs simultaneously
Control frequency is fleeing to abnormal capture, it is also difficult to information match such as the conventional of user, common equipments.For the 3rd
The situation of kind, from the angle of attacker, employs blacklist strategy, the characteristics of having fully taken into account when aggressive behavior occurs.
Based on the matching judgment of above-mentioned three kinds of situations, the accuracy of target account number risk identification can be effectively lifted.
It should be noted that above-mentioned three kinds of different matching ways can be judged and be determined matching result simultaneously;Also may be used
Matching result is determined after judging item by item, i.e., when behavioral data is obtained and finished needed for certain matching way, you can carry out performing this
Correlation step with mode, can effectively lift the ageing of risk identification.When above-mentioned any one situation of every appearance, target account
Number risk just deepen once.When above-mentioned three kinds of situations are all unable to successful match, the greatest risk of target account number.
Step 130, the risk factor for determining target account number according to matching result.
Wherein, risk factor is used for describing the height that target account number there is a possibility that risk, specifically can be regarded as risk
The order of severity, risk factor is higher, illustrates that the safety of target account number is lower.Exemplary, for following two situations:1、
Background server can only count the number of times that same account number is logged in preset time period and exceed preset times threshold value;2nd, backstage
Server not only counts the number of times that same account number is logged in preset time period and has exceeded preset times threshold value, while also monitoring
Mismatch to the current IP address of the account IP address conventional with which.The risk factor of second situation is substantially than the first
The risk factor of situation is high.For situation 1, it is also possible to which user gives password for change and carries out in the case where forgetting Password
Repeatedly attempt.For situation 2, then show that current account number is possible to be stolen by lawless person.Therefore, the determination of risk factor can
Improve the accuracy of account number risk identification scheme.
A kind of account number Risk Identification Method that the embodiment of the present invention one is provided, after the behavioral data for obtaining target account number,
By behavioral data is matched with the historical behavior data of target account number and default abnormal operation recognition strategy, according to matching
As a result the risk factor of target account number is can determine, the accuracy of target account number risk identification is improved, and then is ensured target account
Number safety.
Further, it is determined that the risk of target account number after the risk factor of target account number, can be determined according to risk factor
Grade, the risk class according to determined by can perform corresponding risk and process operation.Exemplary, risk class may be configured as
One risk class and the second risk class.The risk class of target account number is higher, and its safety is poorer.For different risk etc.
The corresponding risk of level processes operation may include following manner:1st, for the first risk class, can be by the way of secondary checking.Example
Such as, account number exception announcement information and identifying code can be sent to communication modes reserved during registration target account number, by inquiry
Whether the login or access request that user is currently initiated to target account number is my operation, and need to be input into corresponding identifying code with
Verified.Wherein, reserved communication modes can be phone number or mailbox for associating with target account number etc..2nd, for second
Risk class, due to the safety of now target account number it is extremely inefficient, therefore can in the form of mandatory modification password, with
Ensure the safety of target account number.It is understood that the present embodiment is not specifically limited to the quantity of risk class, for each
The risk carried out by risk class processes the particular content of operation and is also not specifically limited, and can be set according to practical situation.
