Embodiment 1

[0046] The embodiment of the present invention provides a method for detecting card numbers based on an unsupervised algorithm, the method comprising:

[0047] S101: Collect log data of the operator's power channel login.

[0048] Collect the log data of the operator's telechannel login, including but not limited to the user name phonenumber (phone number), login time logindate, login result loginresult, login IP, IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity) of the login device, etc., among which , for the operator's channel system, the user name generally refers to the mobile phone number. In the embodiment of the present invention, the user name and user both refer to the user's mobile phone number. The IMEI is the serial number of the mobile phone and the "serial number" of the mobile phone, which is used to identify mobile communication devices such as each independent mobile phone in the mobile phone network, and is equivalent to...

Embodiment 2

[0087] with the present invention figure 1 Corresponding to the illustrated embodiment, the embodiment of the present invention also provides a maintenance card number detection system based on an unsupervised algorithm.

[0088] figure 2 A schematic structural diagram of a card number detection system based on an unsupervised algorithm provided by the embodiment of the present invention, as shown in figure 2 As shown, the device includes:

[0089] The collection module 201 is used to collect log data for logging in the operator's electric channel;

[0090] The acquisition module 202 is configured to acquire the user's login behavior features from the login log data, and use the user's login behavior features as a first feature set, and use the high-dimensional statistical features corresponding to the user's login behavior features as a second feature gather;

[0091] The identification module 203 is used to identify each abnormal group corresponding to the first featur...

Abstract

The embodiment of the invention provides a card raising number detection method and system based on an unsupervised algorithm. The method comprises the following steps: 1) collecting operator electriccanal login log data; 2) acquiring login behavior characteristics of the user from the login log data, taking the login behavior characteristics of the user as a first characteristic set, and takinghigh-dimensional statistical characteristics corresponding to the login behavior characteristics of the user as a second characteristic set; 3) identifying each abnormal group corresponding to the first feature set by using an isolated forest algorithm; clustering the features in the second feature set by using a clustering algorithm to obtain a plurality of clusters, and obtaining abnormal clusters according to the stability of the login behavior features; and 4) determining whether the number corresponding to the abnormal group belongs to the card raising number or not according to the number of the numbers clustered into the abnormal cluster in the numbers corresponding to the abnormal group and the proportion of the numbers corresponding to the abnormal group. By applying the embodiment of the invention, the identification accuracy of the card raising number can be improved.

Description

technical field [0001] The invention relates to a maintenance card identification method and system, in particular to a maintenance card number detection method and system based on an unsupervised algorithm. Background technique [0002] With the rapid development of the Internet economy, various online gray industries have emerged more and more. Among them, the Wool Party and Scavenger Party are the most prominent. These people use a large number of accounts to conduct network operations to seek illegal benefits. The basis of the above-mentioned online gray industry is the need for card maintenance. Card maintenance means that some people use certain loopholes or improper means to obtain a large number of activated phone cards in order to seek improper benefits. Although these cards will normally pay monthly usage fees , but no one actually uses it. For example, in order to obtain the remuneration provided by the operator, the agent may activate the phone card in batches t...
