Research On Identification Technology Of Internet Terminal Devices

With the development of computer technology and the popularization of internet terminal devices,the identification technology of internet terminal devices has important theoretical research significance and application value in terms of access control,multi-factor authentication,avoiding cheating attacks and targeted advertising of internet advertisements.The unique serial numbers such as MAC address,IMEI and Android ID are often used in the identification of Internet terminal devices.However,MAC address,IMEI,Android ID are easily forged,easily tampered,and requiring advanced privileges during collectionIn recent years,researchers have proposed device browser fingerprinting technology,which collecting features such as UserAgent,font list and system version from the Internet terminal device through a browser to construct unique fingerprints,and provided an effective method for device identification.However,for traditional terminals such as PCs and laptops,some methods for interrupting browser fingerprinting have also been proposed.Fingerprinting tools can interfere with fingerprinting by restricting the collection of features or forging features.The mobile terminal often upgrades the system and updates the browser which cause the features of the device to change,and the static matching of the fingerprint can not identify the fingerprints caused by the change of the features of the same mobile device.Therefore,this paper made the following research work:1.Aiming at the fingerprints interference of traditional terminal browsers,this paper proposes anti-interference browser fingerprinting generation algorithm based on implicitly acquiring features.Firstly,the algorithm implicitly obtains the feature such as the attribute interpretation difference and the screen resolution by the CSS method,and then uses the font detection method to implicitly obtain the font list information,and finally combines features to generate the fingerprint2.The acquisition of IMEI,Android ID and so on for the mobile terminal device requires high-level authority.The existing static matching method can not identify the fingerprint after the feature changing.This paper proposes a zero-permission mobile device identification algorithm based on similarity of browser fingerprinting.Firstly,zero-permission collect 15 features such as UserAgent,screen resolution to form a fingerprint of the device,and then defining features similarity calculation method according to the different features of the information classification.Finally,using the dynamic matching method based on similarity to identify device.In this paper,the proposed algorithm is experimentally verified,The fingerprinting results of anti-interference browser fingerprinting generation algorithm are not influenced by the interfering tools,and the fingerprinting process can not be detected by the fingerprinting tool.The zero-permission mobile device identification algorithm does not need permission when collecting features,and the method of fingerprint dynamic identification has higher recognition accuracy.
