Abstract
SISTEMAS E MéTODOS PARA A AUTENTICAçãO DE OBJETOS USANDO-SE UMA CODIFICAçãO E UMA DECODIFICAçãO DE IMAGEM DE NìVEL MúLTIPLO Um método de produção de uma imagem codificada de nível múltiplo digital é apresentado. O método compreende a obtenção de uma imagem de autenticação digital, a obtenção de um primeiro conjunto de parâmetro de codificação compreendendo um ou mais parâmetros de codificação, e a construção de uma primeira imagem codificada. A primeira imagem codificada é construída usando-se uma primeira metodologia de codificação, a imagem de autenticação digital e o primeiro conjunto de parâmetro de codificação. O método ainda compreende a obtenção de um segundo conjunto de parâmetro de codificação que compreende um ou mais parâmetros de codificação, e a construção de uma segunda imagem codificada, usando-se uma segunda metodologia de codificação, a primeira imagem codificada e o segundo conjunto de parâmetro de codificação. A segunda imagem codificada pode ser decodificada para revelar a primeira imagem codificada, usando-se um decodificador que tem características correspondentes a pelo menos uma porção dos parâmetros de codificação do segundo conjunto de parâmetro de codificação. A primeira imagem codificada pode ser decodificada para revelar a imagem de autenticação usando-se um decodificador que tem características, correspondentes a pelo menos uma porção dos parâmetros de codificação do primeiro conjunto de parâmetro de codificação.
