Abstract
"TECNICAS DE MARCAçãO PARA RASTREAR CONTEúDO DE MìDIA PIRATEADO". Trata-se de um sistema e método para de forma forense marcar dados de imagem a partir de material fonte. Uma marca forense gerada irá variar de cópia (810) para cópia (815), pela utilização de uma técnica de marcação forense selecionada (810, 815) e de parâmetros de marcação forense que alteram-se de cópia para cópia os dados de imagem fonte.
