Abstract
An improved technique involves authenticating a user based on ability of devices in the user's possession to corroborate environmental information between each other. As part of an authentication process, at least a primary device and a secondary device belonging to a user take readings of a particular set of environmental conditions, such as wireless networks that are active in a room in which they are contained. An authentication server can then verify that the primary and secondary devices are in the same room by corroborating the readings of the environmental conditions read from the primary and secondary devices, and base an authentication result on the corroboration.
