Problems solved by technology

However, this method is not suitable for public network environments such as dynamic IP addresses and campus networks. Because of the variability or repetition of IP addresses, it is easy to cause this method to fail to identify individual users normally.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] Such as figure 1 As shown, a fingerprint identification method, first of all, Hash compares the collected user browser fingerprint information with the saved user browser fingerprint, if there is a match, the recognition result is directly obtained; if there is no match, the target fingerprint Compare the stable fingerprint items one by one with the fingerprints in the fingerprint library, filter out the matching items and compare the similarity of the gradient fingerprints, if the calculation result is greater than or equal to the set threshold, it is determined that the fingerprint item is a browser gradient The final fingerprint and update it.

[0023] Specifically include the follow...

Abstract

The invention discloses a fingerprint recognition method comprising: firstly subjecting acquired user browser fingerprint information and saved user browser fingerprint to Hash comparison, and directly obtaining a recognition result if a matching item exists; if no matching item exists, subjecting the target fingerprint and fingerprints in a fingerprint database to stable fingerprint item comparison one by one, singling out the matching items and performing similarity comparison of gradient fingerprints; and if a calculation result is greater than or equal to a set threshold, determining the fingerprint item as a fingerprint after the gradual change of the browser and updating the fingerprint item. The method improves the accuracy and the stability of a browser fingerprint recognition method for recognizing a returning user in a period of time, and can recognize the returning user more effectively than a general static fingerprint recognition method.

Description

technical field [0001] The invention relates to a fingerprint identification method. Background technique [0002] As browsers become a platform for users to access the Internet, people interact with information from Web sites. Due to the stateless nature of the HTTP protocol, it is impossible to associate user identities with behaviors of accessing pages. Since some commercial websites need to associate users and behaviors in order to provide better services, in 1994 LouMontulli proposed browser cookies for user identification. However, users with high security awareness do not want to expose their online behavior, so browsers provide users with privacy mode and ghost mode, which can be used to help users control or delete Cookies files. [0003] In order to be able to identify the corresponding user when the user's browser fingerprint changes, and to ensure the stability of the user's fingerprint, some sites use both the browser fingerprint and the IP address to determine...
