Abstract

a invenção propõe um dispositivo transmissor, compreendendo uma antena de transmissão, a antena de transmissão (1) compreendendo pelo menos um transdutor (10) e uma unidade de geração de sinal (120) para gerar um sinal de comunicação acústica a ser transmitido a um dispositivo receptor incluindo informação oculta, caracterizado pelo fato de que a unidade de geração de sinal é configurada para gravar um sinal acústico original previamente, tal unidade de geração de sinal sendo capaz de gerar tal sinal de comunicação a ser transmitido pela adição, a um sinal inicial x(t) derivado do sinal original, um sinal auxiliar previamente multiplicado por pelo menos um símbolo, tal símbolo tendo uma fase e/ou uma amplitude transportando a informação oculta e tal sinal auxiliar sendo calculado a partir do sinal inicial por meio de um operador de transformação escolhido que depende de uma chave esteganográfica.
