Abstract
A method and apparatus for determining one or more first devices that are Internet devices meeting all of the following conditions: residing at a given location; equipped with one or more ambience sensing capable sensors; and operation mode being such that their ambience sensing capable sensors should not cause transmission of data. One or more second devices are determined that are Internet devices at the given location and equipped with one or more elements capable of causing an ambient stimulation detectable by the sensors of one or more first devices. Data transmissions of the first devices are monitored. Issuing of the ambient stimulation is caused by a subset of the one or more second devices. It is determined whether the issuing of the ambient stimulation caused a significant change in the monitored data transmissions of the first devices.
