Method and system for extracting and recognizing fingerprint of user equipment

Abstract

The invention discloses a method and system for extracting and recognizing a fingerprint of user equipment. According to the method and system disclosed by the present invention, a manner of collecting device CPU clock offset is adopted so as to realize recognition of the current device, and compared with the prior art, a user no longer has to install a plug-in, so as to simplify an operation process, avoid the risk of failure possibility of the control, and improve stability; and the clock offset cannot be modified almost, so compared with the traditional manners relying on mac addresses and other hardware information, the manner adopted in the invention has higher accuracy. At the same time, the method disclosed by the present invention under the condition of no requirements of installing the control, realizes device recognition, and improves user experience; through a great quantity of simulation tests in a long time, historical data of the equipment is analyzed, and by observing changes of history ip addresses of the same device, accuracy is calculated to be about 99%.

Description

technical field [0001] The invention belongs to the field of the Internet, and relates to a device fingerprint extraction and identification method and system. Background technique [0002] With the development of Internet business, there are higher and higher requirements for user identity identification. The traditional method relies on user name and password. The disadvantage of this method is that the password is easy to leak, the password is too simple and can even be cracked by brute force. In this context, consider the identification of the device used by the user. The current technology basically extracts the machine’s MAC address, CPU number, hard disk number and other hardware device information as the fingerprint of the machine by installing controls. This method has a high accuracy rate but also has obvious disadvantages. Users need to install controls. , the user experience is poor, and the control is easy to conflict with other installed applications, resultin...

[0002] With the development of Internet business, there are higher and higher requirements for user identity identification. The traditional method relies on user name and password. The disadvantage of this method is that the password is easy to leak, the password is too simple and can even be cracked by brute force. In this context, consider identifying the device used by the user

The current technology basically extracts the machine’s MAC address, CPU number, hard disk number and other hardware device information as the fingerprint of the machine by installing controls. This method has a high accuracy rate but also has obvious disadvantages. Users need to install controls. , the user experience is poor, and the control is easy to conflict with other installed applications, resulting in abnormal browsers. Some third-party anti-virus software will recognize the control as a virus and prompt the user to uninstall it. Therefore, identifying the device through the control method also has stability problems.
