Abstract

"MéTODOS PARA INCORPORAR UMA MARCA D'áGUA EM, E PARA SUBTRAIR UMA SEQuêNCIA DE MARCA D'áGUA DE, UM SINAL DE INFORMAçãO, ARRANJOS PARA INCORPORAR UMA MARCA D'áGUA EM, E SUBTRAIR UMA MARCA D'áGUA DE, UM SINAL DE INFORMAçãO, DISPOSITIVO PARA PROCESSAR CONTEúDO MULTIMìDIA, SINAL DE INFORMAçãO POSSUINDO UMA MARCA D'áGUA INCORPORADA MEIO DE ARMAZENAMENTO, ARRANJO, E, DISPOSITIVO PARA TRANSMITIR UM SINAL DE INFORMAçãO". é descrito um método não baseado em quadro e um arranjo para incorporar uma marca d'água em um sinal de informação (x(n)), por exemplo, um sinal de áudio. O método compreende calcular (101) uma convolução não cíclica do sinal de informação com um sinal de marca d'água (v(n)) e combinar 9102) a convolução com o sinal de informação. A convolução não cíclica pode ser calculada por meio de filtragem de Transformada Rápida de Fourier sobreposta.
