1. A volume reflection hologram including a holographic medium, the holographic medium including:
a first optical interference structure which upon a first illumination at a first angle replays by reflection a first holographic recording of a first image including first data; and
a second optical interference structure which upon a second illumination at a second angle different than the first angle replays by reflection a second holographic recording of a second image including second data.
