Abstract
An authentication server determines that a user entering authentication data is in physical possession of a client device by determining that the user has observed changes in the state of hardware elements of the client device that are effected outside of a remote desktop protocol. The authentication server causes the client device to prompt the user to observe the hardware element of the client device for state changes and receives data generated by the user representing observed state changes. If the data accurately represents the changes in the state of the hardware element, the user is determined to be in physical possession of the client device.
