Quantifying privacy leakage in mobile networks

摘要

A method for profiling user activity in a mobile network, including extracting user identifiers from application sessions identified from a mobile network, analyzing the application sessions to determine session blocks based on shared IP address and a minimum separation time threshold, extracting a traffic marker from the session blocks based on a user identifier, identifying a first portion of the session blocks based on the user identifier, wherein the first portion is associated with first mobile network activities of a user identified by the user identifier, identifying a second portion of the session blocks based on the traffic marker, wherein the second portion is associated with second mobile network activities of the user, and analyzing the first portion and the second portion to determine a measure of a mobile network activity of the user.
