Abstract

"PROCESSO, DISPOSITIVO E ARRANJO PARA INSERIR INFORMAçãO EXTRA EM UM SINAL DE ENTRADA EM UM PRIMEIRO DOMìNIO, E, PRODUTO DE PROGRAMA DE COMPUTADOR". Expostos são um processo, dispositivo (100) e arranjo para inserir informação extra em um sinal de entrada (111) no domínio acústico ou visual. Uma representação no domínio elétrico é recebida, uma marca d'água compreendendo a informação extra é gerada e um sinal de marca d'água (113) representando a marca d'água é enviado para o domínio acústico ou visual. Lá, se funde com o sinal de entrada (111). Qualquer unidade de gravação (114) que tenta gravar o sinal de entrada (111) gravará automaticamente o sinal de marca d'água (113) igualmente, assim nenhum espécime não provido com marca d'água é feito disponível. O dispositivo (100) pode ser realizado como um produto de programa de computador, ou como uma pequena unidade portátil, que pode ser usada por uma pessoa para automaticamente prover de marca d'água qualquer coisa que diga. O dispositivo (100) pode ser usado para proteger objetos físicos contra tomada não autorizada de fotografias, projetando um sinal de marca d'água visual para a fonte.
