Problems solved by technology

[0003]However, in the existing market, multiple browsers can be installed on terminal devices, resulting in different FingerPrint hash values ​​of different browsers on the same device, or even the same browser Different versions of will also have different FingerPrint hashes
At the same time, the SDK-based and HTML5-based device fingerprinting methods cannot identify each other's devices
This is contrary to the purpose of device fingerprinting, which in turn leads to the expansion of deviations in subsequent analysis and computing services

Embodiment

[0024] Such as figure 1 Shown is a schematic flow chart of a device fingerprint identification method based on FingerPrint browser information collection of the present invention, the present invention obtains more objective information of the device (such as network type, GPS, etc.) on the basis of the data collected by FingerPrint, and Give up its own Hash algorithm and use another set of independent algorithms to calculate the logo.

[0025] Proceed as follows:

[0026] 1. Partially rewrite the FingerPrint framework to collect more objective information about the device

[0027] a): "one vote veto" features: screen resolution, model, operating system, gpu, touch screen factor, webgl

[0028] b): Secondary features: browser core version, audio frequency, memory size, number of cores, platform, language, fonts, time zone, Storage support, plugins, canvas

[0029] c): variable features: Gps, gravity sensing, network type

[0030] 2. Classify and store matching valid data a...

Abstract

The invention relates to an equipment fingerprint recognition method based on FingerPrint browser information acquisition. The recognition method comprises the following steps: acquiring equipment information through Finger PrintJS2, and transmitting the equipment information to a server for one-ticket negative feature matching; and if the one-ticket negative feature matching result is matching, performing secondary feature matching, if the secondary feature matching result is that the score is higher than a secondary feature threshold, performing variable feature matching, and if the variablefeature matching result is that the difference value conforms to the variable feature threshold range, determining that the recognition result is matching, and transmitting the result to the next link. Compared with the prior art, the method has the advantages of being high in equipment fingerprint recognition accuracy, capable of achieving cross-browser equipment fingerprint recognition, capableof achieving intercommunication between HTML5-based equipment fingerprint recognition and SDK-based equipment fingerprint recognition and the like.

Description

technical field [0001] The invention relates to the technical field of device fingerprint identification, in particular to a device fingerprint identification method based on FingerPrint browser information collection. Background technique [0002] FingerPrint is the most popular open source framework for fingerprint collection and identification of browser devices on the market. Based on pure JS script implementation, it can be embedded into the application program without trace, obtain passively collected browser information and hardware information that can be collected through the browser, and finally use the collected information to give a hash value as a unique identifier. [0003] However, in the existing market, multiple browsers can be installed on a terminal device, resulting in different FingerPrint hash values ​​of different browsers on the same device, and even different versions of the same browser have different FingerPrint hash values. At the same time, the ...
