Abstract:
1. A computerized method for authenticating a media playback device across a computer network, comprising the steps of: determining, at a multi-factor authentication device capable of communicating with said media playback device across said computer network, characteristics of the environment associated with said media playback device based on one or more electromagnetic sensors integrated into said media playback device and capable of measuring and sending data to said multi-factor authentication device across said computer network; forming an initial multi-factor installation signature based on a result of said determining step; recording said initial multi-factor installation signature on a device accessible across said computer network; determining, at said multi-factor authentication device, a subsequent multi-factor installation signature based on data received from said one or more electromagnetic sensors; comparing said subsequent multi-factor installation signature against said initial multi-factor installation signature to define an installation signature change profile; and generating an alarm signal at said multi-factor authentication device, indicating whether said installation signature change profile satisfies a change profile tolerance criterion, wherein said one or more electromagnetic sensors comprise a pyranometer and said characteristics of the environment associated with said media playback device comprise solar irradiance data.
