Abstract
"PROCESSO E ARRANJO PARA DETECTAR UMA MARCA D'áGUA" MULTI-BIT EM UM SINAL, E, PROCESSO E ARRANJO PARA EMBUTIR UMA "MARCA D'áGUA" MULTI-BIT EM UMA IMAGEM DE VìDEO" Um processo e arranjo para detectar uma "marca d'água" mutli-bit em um sinal (por exemplo, uma imagem de vídeo) são descritos. Cada bit do valor multi-bit é representado por uma subconfiguração de "marca d'água" embutida no sinal. Aos invés de detectar de uma maneira convencional a presença de cada subconfiguração individual (isto é, detectar cada bit individual), a detecção compreende as etapas de: detectar (24, 23) a presença da "marca d'água" plena no sinal, independente de seu valor multi-bit, e detectar (25) por qual extensão a presença das subconfigurações corresponde ao valor multi-bit a ser verificado. A confiabilidade da detecção da "marca d'água" é deste modo melhorada.
