Abstract
Establishing trust according to historical usage of selected hardware involves providing a usage history for a selected client device; and extending trust to a selected user based on the user's usage history of the client device. The usage history is embodied as signed statements issued by a third party or an authentication server. The issued statement is stored either on the client device, or on an authentication server. The usage history is updated every time a user is authenticated from the selected client device. By combining the usage history with conventional user authentication, an enhanced trust level is readily established. The enhanced, hardware-based trust provided by logging on from a trusted client may eliminate the necessity of requiring secondary authentication for e-commerce and financial services transactions, and may also be used to facilitate password recovery and conflict resolution in the case of stolen passwords.
