Embodiment Construction

[0031] Before introducing the application scheme, first explain the names or phrases used in the text:

[0032] SimHash is a dimensionality reduction technology that can map high-dimensional vectors to one-dimensional fingerprints. It was first proposed by Google for deduplication of web pages. The input of the SimHash algorithm is a vector, and the output is an f-bit fingerprint. For the convenience of presentation, it is assumed that the input is a feature set of user behavior, and each feature has a corresponding weight. The SimHash algorithm is as follows:

[0033] 1. Initialize a vector V of f dimension (where f is 64) to 0, and initialize the binary number S of f bits to 0;

[0034] 2. For each feature: use the traditional hash algorithm to generate an f-bit fingerprint b for this feature, for i=1 to f, if the i-th bit of b is 1, add this feature to the i-th element of V The weight of (here the weight is 1); otherwise, the i-th element of V minus the weight of the feat...

Abstract

The invention discloses a method and device for detecting a flow generating tool. The method comprises the steps of acquiring behavior data of at least one user corresponding to a to-be-detected channel, generating behavior characteristics of each user according to the behavior data of each user, calculating a behavior characteristic value of each user by virtue of the behavior characteristics of each user, classifying the users by taking the behavior characteristic value as a classifying condition so as to obtain a plurality of classifying groups, and determining that the flow generating tool is used by the to-be-detected channel when the number of the users in the classifying groups meets a preset judgment strategy. The behavior characteristic values of the users in each classifying group are similar or same, so that if the number of the users in one or multiple classifying groups is very large, most users in the classifying one or multiple classifying groups are false users, and the flow generating tool is used by the to-be-detected channel. According to the method, the limitation problem of existing methods for detecting the flow generating tool based on the distribution of attribute parameters of a hardware access environment is solved.

Description

technical field [0001] The present application relates to the field of network technologies, and more specifically, relates to a method and device for detecting brush amount tools. Background technique [0002] The popularization of smart terminals such as smart phones provides carriers for various types of applications (Applications, applications). In order to promote their own applications, application providers display applications to users through various platforms and provide download functions. Each platform can be regarded as a channel for application promotion. As a reward, whenever a new user registers an application account through a certain channel, the application provider needs to pay a certain promotion fee to the channel. [0003] In reality, some channels (platforms) will generate false new users by using the brushing tool in order to defraud application providers of promotion fees. The process is roughly as follows: the channel uses the brushing tool to gen...
