Detailed Description
Fig. 1 is a diagram showing a structural example of a black product identification system according to an embodiment of the present application. As shown in fig. 1, the black product identification system of the present embodiment may include a 3A log database of an operator, a data conversion device, a terminal device, a black product account verification system, and a black product account library.
The 3A log is original data information unique to the operator, and includes a broadband account, a mobile phone number associated with the broadband account, a login time of the broadband account when accessing the network each time, an IP address and an online time length after accessing the network each time, how much traffic is used after the broadband account accesses the network, and the like. An example of a login time is a month, day, minute, and second.
The data conversion device generates a black-out account library based on the 3A log data. For example, the data conversion apparatus determines whether a broadband account is a blackout account according to the number of times of conversion of an IP address associated with the broadband account in one period of time in the 3A log data. For another example, the data conversion device determines whether the mobile phone account is a blackout account according to the conversion of the IP address associated with one mobile phone number in a time period in the 3A log data. For another example, the data conversion device determines whether the broadband account is a blackout account according to the average online time length of each IP address associated with the broadband user in the 3A log.
Included in the blackout account library is a broadband account identified as a blackout account. In addition, the cell phone number account associated with the blackout broadband account is also identified as the blackout account. The black production account library can also record the black production behavior occurrence time of each black production broadband account.
The terminal device may access the blackout account identification system through an application (App) or a website. For example, when the terminal device needs to identify whether a certain mobile phone number is a blackout account, the mobile phone number can be sent to the blackout account identification system based on a blackout identification App or a blackout identification website on the terminal device so as to request the blackout account identification system to identify. An example of a terminal device is a mobile phone.
After the mobile phone number sent by the terminal equipment is received by the black-date account identification system, information in the black-date account library can be read, whether the mobile phone number requested to be identified by the terminal equipment is the black-date account or not is identified according to the read information, and an identification result is sent to the terminal equipment.
Fig. 2 is a flowchart of a black product identification method according to an embodiment of the present application. As shown in fig. 2, the method may include S201, S202, S203, S204, S205, and S206.
S201, the terminal equipment sends a black product identification request message to a black product account verification system, wherein the black product identification request message carries a mobile phone number to be identified, the login time of the mobile phone number to be identified and an IP address used by the mobile phone number to be identified at the login time. Accordingly, the blackout account verification system receives the blackout identification request message.
The blackout identification request message is used for requesting the blackout account verification system to verify whether the mobile phone number to be identified is a blackout mobile phone number or not, or is used for requesting the blackout account verification system to verify whether the behavior of the mobile phone number to be identified for logging in by using the IP address at the login time is blackout or not.
The terminal device can be a mobile phone or a computer. The terminal device can send the blackout identification request message to the blackout account verification system through the APP or the website. The mobile phone number to be identified in this embodiment may also be referred to as a mobile phone number that needs to be verified.
In this embodiment, the login time of the mobile phone number to be identified may be understood as a time when the user account associated with the mobile phone number to be identified accesses or logs in to the service system, and the IP address used by the mobile phone number to be identified at the login time may be understood as an IP address used by the user account associated with the mobile phone number to be identified accesses or logs in to the service system at the login time.
The business system in this embodiment may be any system capable of providing services to the user, and may be, for example, a shopping website or a scoring website.
In this embodiment, the IP address may be an IPV4 address or an IPV6 address, where the IP address may be an address allocated by the telecommunications access network for a device (e.g. a mobile phone) used when logging into the service system using the mobile phone number. The address allocated by the telecom access network to the equipment (such as a mobile phone) used when logging in the service system by using the mobile phone number is changed continuously along with the online and offline of the account of the mobile phone number.
S202, judging whether the behavior of using the IP address by the mobile phone number to be identified at the login time is black production or not according to the distance between the mobile phone number to be identified and the black production mobile phone number in the black production account library.
The step can be called as carrying out fuzzy matching black product identification on the mobile phone number to be identified, and the identification result is called as a fuzzy black product identification result.
The blackout account library can comprise mobile phone numbers initiating the overblackout behavior, and the mobile phone numbers initiating the overblackout behavior can be called blackout mobile phone numbers.
In one example of fuzzy matching of the mobile phone number to be identified by the black-out account verification system, the following formula may be used to calculate the fuzzy matching distance between the mobile phone number to be identified and each black-out mobile phone number in the black-out account library:
k＝1,2,3,…,Ω
in the formula, omega is the number of the black-out mobile phone numbers in the black-out account library; i. j and t are the three-dimensional coordinates of the three-dimensional storage space point of the mobile phone number to be identified respectively, S mi For the last 10 digits of the cell phone number to be identified,the last 10 bits of the kth black-out mobile phone number in the black-out account library, D k (i, j, t) is a fuzzy matching distance between the mobile phone number to be identified and the kth mobile phone number in the black account library, and 'mod' represents a remainder operation.
After the fuzzy matching distance between the mobile phone number to be identified and each mobile phone number of the black product in the black product account library is calculated by the black product account verification system, the minimum fuzzy matching distance can be selected, and the mobile phone number to be identified is identified as the black product based on the login behavior of the IP address at the login time under the condition that the minimum fuzzy matching distance is smaller than or equal to a preset fuzzy matching distance threshold value. In this case, the fuzzy black yield identification result may include: and the information is used for indicating that the mobile phone number to be identified is identified as black product based on the login behavior of the IP address at the login time.
It can be understood that the above formula for calculating the fuzzy matching distance is only an example, and other formulas for calculating the fuzzy matching distance between the mobile phone number to be identified and the mobile phone number of the black product may be used in the embodiment, for example, the manhattan distance or the cosine distance between the mobile phone number to be identified and the mobile phone number to be identified may be calculated as the fuzzy matching distance.
S203, the black product account verification system sends a fuzzy black product identification result to the terminal equipment. Correspondingly, the terminal equipment receives the fuzzy black product identification result sent by the black product account verification system.
S204, the blackout account verification system determines the broadband account associated with the mobile phone number to be identified when the IP address is used in the login time as the broadband account to be identified according to the information carried in the blackout identification request message.
In this embodiment, the broadband account to be identified may also be referred to as a broadband account associated with the phone number to be identified when the IP address is used at the login time.
For example, a blackout account verification system may determine a broadband account with which the phone number to be identified is associated when the IP address is used at the login time based on a 3A log database of an operator.
S205, the blackout account verification system judges whether the behavior of using the IP address by the mobile phone number to be identified at the login time is blackout or not according to the distance between the broadband account to be identified and the blackout broadband account in the blackout account library and the distance between the login time and the blackout time of the blackout broadband account.
The black-out account library may also include broadband accounts that are over-black-out, which may be referred to as black-out broadband accounts. Further, the black production account library records the black production behavior time of each black production broadband account, and the black production behavior time of the black production broadband account can be called the black production time of the black production broadband account.
This step can be understood as: and the black-produced account verification system performs accurate verification of the annual, daily, time and second granularity on the broadband account to be identified and each black-produced broadband account in the black-produced account library.
For example, the blackout account verification system calculates the time exact matching distance between the broadband account associated with the received phone number and each broadband account in the blackout account library according to the following formula:
x＝1,2,3,…,C
in the formula, C is the number of the black band accounts in the black product account library;is->Is a transpose of (2); mu is an adjustment coefficient; l is an autonomous adjustment time range; />A login time based on the IP address for the mobile phone number to be identified; />For the blackout time of the x-th broadband account in the blackout account library,/->For the broadband account to be identified, +.>D, for the xth black-producing broadband account number in the black-producing account library x For accurate matching distance of moment between the broadband account to be identified and the xth black-producing broadband accountAnd (5) separating. Wherein μ and L are both empirically set.
After the moment accurate matching distance between the broadband account to be identified and each black-produced broadband account in the black-produced account library is calculated, the minimum moment accurate matching distance is found out, and whether the minimum moment accurate matching distance is smaller than or equal to an accurate matching distance threshold value is judged. If the minimum time accurate matching distance is smaller than or equal to the accurate matching distance threshold, the mobile phone number to be identified can be accurately considered to be a black product in the login time based on the login behavior of the IP address. In this case, the obtained accurate black yield identification result for performing the accurate black yield identification may include: and the information is used for indicating that the identification of the mobile phone number to be identified is black at the login time based on the login behavior of the IP address.
Optionally, the accurate black product identification result may further include the mobile phone number to be identified, the login time and the IP address, so that the terminal device can obtain the mobile phone number, the login time and the IP address corresponding to the black product. Further, the accurate black product identification result can also include a broadband account associated with the mobile phone number to be identified.
It will be appreciated that the above formula for calculating the precise matching distance of the time is only an example, and other formulas for calculating the precise matching distance of the time between the broadband account to be identified and the black-producing broadband account may be used in the present embodiment, for example, the manhattan distance between the broadband to be identified and the black-producing broadband account, the manhattan distance between the login time and the black-producing time may be calculated, and the precise matching distance of the time may be calculated according to the manhattan distances.
S206, the black product account verification system sends an accurate black product identification result to the terminal equipment. Correspondingly, the terminal equipment receives the accurate black product identification result.
In this embodiment, the blackout identification request message may further carry identification requirement indication information, where the identification requirement indication information is used to indicate whether to request the blackout account verification system to provide the fuzzy blackout identification result.
If the identification requirement indication information indicates that the blackout account verification system is requested to provide the fuzzy blackout identification result, the blackout account verification system may firstly perform S202 and S203 to provide the fuzzy blackout identification result to the terminal device, and then perform S204 to S206 to provide the accurate blackout identification result to the terminal device.
If the identification requirement indication information indicates that the blackout account verification system is not requested to provide the fuzzy blackout identification result, the blackout account verification system may not perform S202 and S203.
If the blackout identification request message does not carry identification requirement indication information, or the identification requirement request information does not indicate whether the blackout account verification system is requested to provide a fuzzy blackout identification result, the blackout account verification system can determine whether to execute S202 and S203 according to a default setting. The default setting may be to execute S202 and S203 by default, or may not execute S202 and S203 by default.
Fig. 3 is a schematic structural diagram of a black product identification device according to an embodiment of the present application. The apparatus shown in fig. 3 may be used to perform the method described in any of the previous embodiments.
