A method and device for identifying a shared access terminal

Abstract

The embodiment of the present invention discloses a method and device for identifying a shared access terminal. The method includes: calculating the time difference between the client timestamp obtained after each client runs the preset file and the corresponding local timestamp of the preset file sent locally , calculate the mean value of the total time difference according to each time difference; group each time difference according to the preset time period, and calculate the mean group time difference of the time difference of each group; if it is judged that the number of time differences in the target group is less than the threshold and the mean If the average value is within the preset range, it is determined that the clients corresponding to the time difference of the target group are the same shared access terminal. By calculating the time difference between the client time stamp of each client and the corresponding local time stamp, group judgment is performed to determine that the clients corresponding to the time difference in the group are the same shared access terminal, and further identify the number of shared access terminals, It can solve the problem that terminals installed by multiple ghosts cannot be recognized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for identifying a shared access terminal. Background technique [0002] With the development of communications and electronic devices, various terminal devices have entered people's lives, and they are connected to the Internet through wireless, which is convenient for users but also creates huge security risks. Especially in the company, there are strict regulations on whether shared access can be accessed, how many computers, and how many mobile terminals can be accessed. However, many computers are installed through the ghost system, which makes the characteristics of the computers very similar, making it difficult to be identified and distinguished in a shared access environment. [0003] In the prior art, there are usually two methods for identifying two computers sharing access: the first method is through application ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the embodiment of the present invention, the inventor found that when the existing method recognizes the shared access terminal through the feature, only when some special applications are installed on the terminal, these applications carry the MAC address of the terminal when accessing the webpage. , extracting these MAC features can identify different terminals, but when identifying a terminal installed by ghost, it is very dependent on the application and is very unreliable; when using flashcookie push, when identifying by obtaining the font and browser type of the terminal, if two The terminal installed with ghost will not be recognized
