AI Technical Summary

Problems solved by technology

[0004] To sum up, the current literature mainly studies the working principle of different types of browser fingerprints and the method of interference fingerprint generation. Few literatures focus on the problem that the static matching method of fingerprints cannot completely identify returning users after the change of characteristic parameters.

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] Please refer to figure 1 , the present invention provides a kind of return visit user identification algorithm based on browser fingerprint difference degree, it is characterized in that, comprises the following steps:

[0055] Step S1: collecting fingerprint feature parameters and using a hash function to make fingerprints;

[0056] Step S2: Determine whether the fingerprint exists in the fingerprint library, if it exists, determine that the fingerprint is the fingerprint of the returning user, otherwise proceed to step S3;

[0057] Step S3: Calculate the global difference value between the fingerprint and all the fingerprints in the fingerprint library one by one;

[0058] Step S4: If there is a global difference value less than the threshold (the threshold is 0.025, 0.05 or 0.1), then determine that the fingerprint is an upgraded fingerprint...

Abstract

The invention relates to a return visit-paying user identification algorithm based on browser fingerprint differences. The method comprises the steps of collecting fingerprint feature parameters and making a fingerprint by using a Hash function; judging whether the fingerprint exists in a fingerprint database, judging the fingerprint as the fingerprint of a return visit-paying user if yes, and performing the next step if no; calculating the global difference values between the fingerprint and all fingerprints in the fingerprint database one by one; if one global difference value is less than a threshold value, determining that the fingerprint is an upgraded fingerprint of a return visit-paying user, and updating the current fingerprint corresponding to the global difference value in the fingerprint database to the upgrade fingerprint; otherwise, determining that the fingerprint is the fingerprint of a new user and storing the fingerprint into the fingerprint database. The identification rate of the return visit-paying user identification algorithm is increased and the misjudgment rate of identification is reduced.

Description

technical field [0001] The invention relates to a revisiting user identification algorithm based on browser fingerprint difference degree. Background technique [0002] Browser fingerprinting is mainly used in user tracking, identity authentication, user identification and other fields. Browser fingerprinting is an identification method based on the combination of browser information. Through the browser platform, the screen information, plug-in information, font information and other characteristic parameters of the device are obtained from the configuration information, software composition, and hardware composition levels, and combined to form Fingerprint data that can uniquely identify a user. Wherein, the collected fingerprint feature parameters are inherent state information of the user, rather than private information of the user. [0003] At present, the following research results have been obtained on browser fingerprinting technology: Peter Eckersley and others p...
