1. A mobile system configured to detect data communication via visible light emitted by a light source, the mobile system comprising:
a camera; and
at least one processor configured to capture an image with said camera, to determine whether any object of a plurality of objects is recognized in said captured image and to start detecting whether data is being communicated via visible light associated with any object of the plurality of objects, regardless of which object of the plurality of objects is recognized in said captured image by the at least one processor, only after said recognized object has been recognized, to obtain a decryption key associated with said recognized object, to change a setting of said camera to start said detecting whether data is being communicated via visible light in response to determining that said recognized object is recognized, to decode at least part of said data which is communicated via visible light using said obtained decryption key, to activate a further sensor to start said detecting of whether data is being communicated in response to determining that said recognized object is recognized, and to monitor whether a signal received from said further sensor comprises data communicated via visible light and to deactivate said further sensor in response to determining that said signal does not comprise data communicated via visible light, said further sensor having a wider view than said camera.
