Abstract (en)
[origin: WO2015140252A1] The invention relates to a method for identifying, via a first terminal, a content being displayed on a screen of a second terminal located in the same space as the first terminal. This method comprises the following steps: collecting with the first terminal the luminosity produced in said space by the screen of the second terminal; generating with the first terminal at least one digital fingerprint depending on the collected luminosity; comparing the fingerprint generated to a reference fingerprint stored beforehand in a memory; and identifying the content depending on the result of said comparison.
