Abstract

"TéCNICAS PARA DETECTAR, ANALISAR E UTILIZAR PADRõES DE AUTENTICAçãO VISìVEIS" Tratam de técnicas aperfeiçoadas para construir padrões de detecção de cópia e utilizar os mesmos para detectar relações de cópia entre representações digitais. As técnicas incluem técnicas para incluir uma mensagem em um padrão de deteccão de cópia sem alterar a entropia dos padrões de detecção de cópia e a leitura das mensagem, técnicas para utilizar um padrão de deteccão de cópia em uma forma analógica para determinar se a forma analógica é uma forma analógica original sem referência a uma representação digital do original do padrão de detecção de cópia da forma analógica, técnicas para aumentar a sensibilidade da detecção de cópia utilizando os padrões de detecção de cópia por modificar um dos dois padrões de detecção de cópia que estão sendo comparados para levar em consideração resultantes do processo de cópia, técnicas para distribuir um padrão de detecção de cópia através de um documento e técnicas para utilizar a entropia de um padrão de detecção de cópia para localizar o padrão de detecção de cópia. Também são reveladas aplicações dos padrões de detecção de cópia com cópia que envolve transformações entre as formas digitais e analógicas e com a cópia de digital para digital.
