In an embodiment of the present invention, the predetermined time period is a preset statistical time period, for example, 1 day. Each time a user logs in, the system platform generates a login record comprising a login account number, a login equipment identifier, login starting time, login duration and the like, and the system platform automatically records and stores the login record in a database of the system platform.
In an embodiment of the invention, after the bonus event is ended and before the bonus event is received, a user login record during the holding period of the bonus event is obtained, wherein the login record comprises a user login account and a CPU serial number of a login device aiming at sequential login behaviors.
Continuing with FIG. 2, in step S210: and determining the login account number of the login equipment corresponding to the login equipment identification in the first preset time period aiming at each login equipment identification based on the user login record in the first preset time period.
In an embodiment of the present invention, as shown in fig. 3, step S210 may include:
step S2101: for each login equipment identifier, acquiring a user login account with the login equipment identifier from the user login record in the first preset time period;
step S2101: and determining the number of user login accounts with the same login equipment identifier in the acquired user login record.
In an embodiment of the present invention, the obtained login device identifier set corresponding to the login account in the predetermined time period is {11 }123，12234，45123，56123，7845211, 12, 45, 56, and 78 are login accounts, subscript numbers 123, 234, and 452 of the login accounts are login account identifiers, and it is determined that the number of login accounts with the same login equipment identifier in a login equipment identifier set corresponding to the login account within a predetermined time period is 11, 45, and 452, where the login account corresponding to the login equipment identifier 123 is 11, 45, and 56, the login account corresponding to the login equipment identifier 234 is 12, the login account corresponding to the login equipment identifier 452 is 78, the number of login accounts corresponding to the login equipment identifier 123 is 3, the number of login accounts corresponding to the login equipment identifier 234 is 1, and the number of login accounts corresponding to the login equipment identifier 452 is 1.
Continuing with FIG. 2, in step S220: and if the number of login accounts of the login device corresponding to the login device identifier in the first preset time period is larger than a preset login account number threshold value aiming at one login device identifier, taking the login account of the login device corresponding to the login device identifier in the first preset time period as a candidate login account.
In an embodiment of the present invention, the threshold is predetermined, and may be determined according to experience of an operator of the system platform, or according to a strict market research conclusion, or may be obtained by determining, based on a quotient between a total number of registered accounts in the system and numbers of different biometric information under the same type of biometric information in the database, that is, if a user needs to provide face information of the user when registering an account of the system, and one user may have multiple accounts registered at the same time, but the used face information is of the same person, multiple accounts corresponding to the same face information are associated accounts, and the associated accounts are basically used on the same login device to log in the system platform. When a user a registers 3 accounts, a user b registers 1 account, a user c registers 10 accounts, and a user d registers 6 accounts, the determined threshold is 5, and the number of accounts held by the user c and the user d exceeds the threshold 5, the 10 accounts corresponding to the user c and the 6 accounts corresponding to the user d are determined as candidate login accounts.
In an embodiment of the present invention, the threshold may also be obtained by determining, based on a quotient between a total number of registered accounts in the system and a number of identifiers of the login devices recorded in the database, where, for example, the number of identifiers of the login devices recorded in the database is 4, where 1 login account corresponds to the login device 1, 5 login accounts corresponds to the login device 2, 64 login accounts corresponds to the login device 3, 30 login accounts corresponds to the login device 4, and the total number of login accounts is 100, then the threshold determined based on the total number of login accounts 100 and the total number of login devices 4 is 25, where the number of login accounts corresponding to the login device 3 and the login device 4 is greater than the threshold 25, and then 94 accounts that log in the platform through the login device 3 and the login device 4 are determined as candidate login accounts.
Continuing with FIG. 2, in step S230, an authentication request is sent to each candidate login account, the authentication request including a gesture name.
In an embodiment of the present invention, the gesture refers to a specific action and body position of a person when the person uses an arm, and the gesture name refers to a uniform name formed by the person for a common gesture in life. If the gesture name included in the authentication request sent to the candidate login account is "thumb up", the user knows that he should take a gesture picture of holding the thumb.
In an embodiment of the present invention, as shown in fig. 4, before step S230, the method may further include:
step S228: randomly extracting a gesture from a preset gesture set;
step S229: and randomly extracting a name corresponding to a gesture from a preset gesture set to serve as the gesture name included in the verification request.
In an embodiment of the invention, if an "OK gesture", "a gesture of raising the thumb", "a V-shaped gesture", "a gesture of raising the middle finger", "a gesture of clenching the fist" exist in the preset gesture set, a gesture corresponding to the "gesture of raising the thumb" is randomly extracted from the preset gesture set as the "gesture of raising the thumb", and a gesture name corresponding to the "gesture of raising the thumb" is put into the verification request and sent to the candidate account.
In an embodiment of the present invention, the gestures in the preset gesture set are not constant, a preset update period is set, the updated gestures are periodically updated into the preset gesture set, and the total number of the gestures in the gesture set is not constant, for example, if there are 90 gestures in the preset gesture set, when the gestures are updated, 20 new gestures are updated into the original preset gesture set, and 20 gestures are randomly extracted from the original gesture set to move out of the original gesture set, so as to maintain the total number of the gestures 90 constant.
Through the mode of randomly extracting the gestures and the mode of regularly updating the gestures, malicious technicians such as a technical wool party can be reduced, mass copying is carried out through a preset fixed gesture model so as to pass verification, in addition, the difficulty of related malicious technicians for breaking verification is increased, and therefore the harm of the technical wool party to a system platform is reduced.
Continuing with FIG. 2, in step S240, biometric information of each candidate login account and a gesture photo by the gesture name are received.
In an embodiment of the present invention, the biometric information may be a fingerprint of the user, or an iris, a face, a palm print of the user, and the like, for example, after the user receives the authentication request, the content of the authentication request is "please input the fingerprint and take a gesture picture of holding up a thumb", the user enters the fingerprint information of the user through the fingerprint authentication device configured on the login device, and takes the gesture picture of holding up the thumb required in the authentication request through the image pickup device configured on the login device, and the server receives the fingerprint information of the user and the gesture picture of holding up the thumb acquired by the login device.
In an embodiment of the present invention, after step S230, the method may further include: and if the biological characteristic information sent by the candidate login account and the gesture photo according to the gesture name are not received in a second preset time period after the verification request is sent to the candidate login account, determining that the candidate login account is an abnormal account.
In an embodiment of the invention, after the technical wool party receives the verification request, because gesture names contained in the verification requests received by the multiple account numbers are different, the technical wool party cannot copy in a large scale and passes the verification through a fixed gesture model, if all the account numbers pass the verification, a long time is needed, and by setting the verification time, the number of the account numbers controlled by the technical wool party passing the verification can be reduced, so that the damage of the technical wool party to a system platform is reduced, and more abnormal account numbers are identified.
As shown in fig. 2, in step S250, the received biometric information is compared with the biometric information registered when the candidate login account is registered.
In an embodiment of the present invention, if a fingerprint sent by a candidate account is received, a feature vector corresponding to the fingerprint is extracted and compared with a feature vector corresponding to a fingerprint entered by the candidate account during registration, which is stored in a database.
Continuing to refer to fig. 2, in step S260, if the comparison is consistent, a gesture is recognized from the gesture photographing, and it is determined whether the recognized gesture corresponds to the gesture name.
In an embodiment of the present invention, if a feature vector corresponding to a fingerprint entered by the candidate account at the time of registration stored in the database is the same as or has an error within a preset threshold range with respect to a feature vector corresponding to a verification fingerprint sent by the candidate account, it is determined that the comparison is consistent, and then a gesture name corresponding to a gesture in gesture photographing is identified, and the identified gesture name is compared with a gesture name included in a verification request sent to the candidate account, where if the identified gesture name corresponding to the gesture photographing is a "thumb raising gesture", and the gesture name included in the verification request sent to the candidate account is a "thumb raising gesture", it is determined that the identified gesture name corresponding to the gesture photographing is consistent with the gesture name included in the verification request sent to the candidate account.
Continuing to refer to fig. 2, in step S270, if the received biometric information is inconsistent with the biometric information registered during registration of the candidate login account, or the recognized gesture does not correspond to the gesture name, it is determined that the candidate login account is an abnormal account.
In an embodiment of the present invention, if the biometric information sent by the candidate account is not consistent with any verification of the gesture photographing, it is determined that the candidate account is an abnormal account, and if the fingerprint sent by the candidate account is not consistent with the fingerprint corresponding to the account stored in the database after verification, it is determined that the candidate account is an abnormal account;
in another embodiment of the present invention, if the fingerprint sent by the candidate account is verified to be consistent with the fingerprint corresponding to the account stored in the database, and the gesture name corresponding to the gesture identified in the gesture photo sent by the candidate account is inconsistent with the gesture name included in the verification request sent to the candidate account, the candidate account is also determined to be an abnormal account.
In another embodiment of the invention, in order to prevent a technical-class woollen party from extracting gestures corresponding to all gesture names in a preset gesture set through a large number of tests and pre-establishing corresponding gesture models to cope with random gesture verification in the technical scheme of the invention, when the biometric information verification and the gesture verification of a candidate account are successful, the time corresponding to the successful verification of the corresponding biometric information and the successful verification of the gesture is recorded, and when the number of successful verification of the candidate login account corresponding to the same login equipment identifier in the preset threshold time exceeds the preset threshold number, the candidate login account corresponding to the login equipment identifier is determined as an abnormal account. Through the technical scheme, the behavior of bedding wool can be further inhibited through the technical means of large-batch quick verification of the technical wool party, and the damage of the technical wool party to a system platform is reduced.
In an embodiment of the present invention, after step S270, the method further includes: and freezing the abnormal account and the login equipment corresponding to the abnormal account.
If the candidate login account is an abnormal account, freezing the abnormal account for a predetermined time to prevent related malicious persons from continuously operating the abnormal account to damage a system platform, wherein the freezing time can be determined according to experience in advance or can be determined according to the following method, and is determined based on the product of the number of the abnormal accounts corresponding to the same login equipment identifier and a preset number of days, if the number of the abnormal accounts corresponding to one login equipment is 50 and the preset number of days is 100 days, freezing each account in the 50 abnormal accounts corresponding to the login equipment for 5000 days.
In an embodiment of the present invention, after freezing the abnormal account and the login device corresponding to the abnormal account, the method may further include: and if the thawing complaint request sent by the abnormal account is not received within a third preset time period, the abnormal account is logged out.
If the account is frozen by mistake, if the frozen account is the account held by the real user, the frozen account is defrosted within a certain time, so that the defrosted account is defrosted, and the frozen account is cleared by setting a preset unfreezing period, if the unfreezing complaint is not received during the preset unfreezing period, the junk information stored in a system platform database can be reduced, the processing efficiency of a system platform is improved, and more accounts can be released for the real user to obtain and use.
