Embodiment Construction

[0048] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can propose multiple structural modes and implementation modes that can be replaced without changing the essence and spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0049] It should be understood that, for historical device fingerprint behavior data, a common practice is to cluster similar device fingerprints to achieve the purpose of improving stability. Usually clustering similar individual problems will consider unsupervised learning clustering methods (Clustering Algorithm), such as K-means, Gaussian Mixture, Hirachical Clustering and other algorithms.

Abstract

The present invention proposes a fingerprint similarity identification method and device for anti-flash machine equipment. The method includes the following steps: collecting the feature fields of the device fingerprints. The feature fields are extracted from user login behavior data, including simple statistics, aggregate features and Fields with time stamp set features; calculate the similarity score between each feature field of the fingerprints of two devices; judge whether the fingerprints of two devices are the same device according to the preset similarity score threshold, and add tags; use yes or Construct the supervised learning model and output the device fingerprint similarity score corresponding to the negative label; input the device fingerprint similarity score corresponding to the unknown label into the supervised learning model for recognition, and obtain the recognition result. The invention adopts the hybrid device fingerprint processing technology, effectively avoids the shortcomings of active and passive device fingerprint technologies, solves the problem of complex data processing time, balances cost and effectiveness, and achieves better results.

Description

technical field [0001] The invention relates to the technical field of Internet information security, in particular to a fingerprint similarity identification method and device for an anti-flash machine device. Background technique [0002] Since the technological wave of smart terminals has brought the whole world into the "Internet +" era, while the mobile Internet has expanded the application range and scenarios of the Internet and created more business opportunities, its ecological characteristics centered on mobile apps have also given Enterprise sales in the new era bring new challenges. In fields such as promotion effect tracking, business fraud prevention, and operational effect evaluation, enterprises urgently need a new device identification and tracking technology to distinguish valuable users, malicious users and even fraudulent gangs, to ensure the overall profitability of the enterprise, and Maximize ROI from marketing and business operations. [0003] At pre...
