Abstract
A method for detecting proxy internet access includes intercepting an access request from a proxied terminal of a same internet account; and sending a redirection packet to the proxied terminal sending the access request. The redirection packet carries a first timestamp indicating when the redirection packet is sent. The method also includes receiving a reported timestamp difference between the first timestamp and a second timestamp. The second timestamp is a system time of the proxied terminal acquired after the proxied terminal receives the redirection packet. Further, the method includes executing a clustering process on the reported timestamp difference to obtain a clustering result; and based on the clustering result, detecting whether the same internet account is a proxy account.
