Using a change in information associated with a mobile device network ID as a risk indicator in mobile network-based authentication

摘要

The network ID of a mobile device can be securely employed as a possession factor. When an access to a restricted access application server or a restricted access account on the application server is attempted via a computing device, and possession of a mobile device programmed with a network ID is employed as a verification factor, the application server or a network ID monitoring server can determine whether certain information associated with the network ID has been changed within a predetermined time interval, indicating potentially fraudulent activity. Based on the presence or absence of recent changes in the information associated with the network ID, the user activity is either authorized or denied.
