Abstract

Selon un aspect, la présente invention concerne un émetteur optique d'auto-identification pour diffuser un code d'authentification unidirectionnelle à l'aide d'une communication basée sur la lumière. L'émetteur peut comprendre une mémoire pour stocker un identificateur de l'émetteur, un processeur pour générer un signal de données comprenant un identificateur de l'émetteur, un modulateur pour recevoir le signal de données et générer un signal électrique, le modulateur générant le signal électrique par modulation du signal de données. L'émetteur peut également comprendre une source de lumière pour recevoir le signal électrique, convertir le signal électrique en un signal optique, et diffuser en continu le signal optique sous la forme d'un flux de transmission de données optiques. Le flux de transmission de données optiques peut être utilisé pour vérifier qu'un dispositif mobile de réception est près de l'émetteur. L'émetteur peut également comprendre une surface optique pour disperser le flux de transmission de données optiques lorsque le flux de transmission de données optiques est émis à partir de l'émetteur.
