\u00c9 proposta uma estrutura unificada que proporciona um n\u00edvel de seguran\u00e7a mais elevado para os passaportes eletr\u00f4nicos. Esta estrutura integra imagens de rosto, \u00edris e impress\u00f5es digitais. Ela envolve tr\u00eas camadas de seguran\u00e7a: a primeira camada mapeia uma imagem biom\u00e9trica para outra imagem biom\u00e9trica que \u00e9 chamada de imagem biostego. Tr\u00eas esquemas de mapeamento s\u00e3o propostos: o primeiro esquema mapeia uma imagem biom\u00e9trica \u00fanica para uma imagem biostego \u00fanica, o segundo esquema mapeia imagens biom\u00e9tricas duplas para uma imagem biostego \u00fanica, o terceiro esquema divide a imagem biom\u00e9trica em se\u00e7\u00f5es e mapeia cada se\u00e7\u00e3o para uma imagem biostego diferente. Uma fun\u00e7\u00e3o de mapeamento mapeia o valor de intensidade de cada pixel na imagem biom\u00e9trica para pixels com a mesma intensidade na imagem de biostego. Um pixel representativo \u00e9 selecionado aleatoriamente do conjunto de pixels, e suas coordenadas s\u00e3o registradas no mapa de localiza\u00e7\u00e3o da imagem biom\u00e9trica. Na segunda camada, o mapa de localiza\u00e7\u00e3o \u00e9 codificado usando o cofre de impress\u00e3o digital. Na terceira camada, o mapa de localiza\u00e7\u00e3o codificado \u00e9 escondido na imagem biostego usando a t\u00e9cnica de esteganografia. A imagem biostego que cont\u00e9m o mapa de localiza\u00e7\u00e3o codificado \u00e9 armazenada na mem\u00f3ria do e-passport. Mantendo o esquema de mapeamento em segredo e usando as impress\u00f5es digitais em ab\u00f3bada difusa para criptografar o mapa de localiza\u00e7\u00e3o, a abordagem proposta oferece maior n\u00edvel de prote\u00e7\u00e3o contra fraudes.<\/span><\/p>\n

Dr. Khaled A. Nagaty<\/a> \u00e9 professor de inform\u00e1tica e diretor de eLearning universit\u00e1rio na Universidade Brit\u00e2nica no Egito. O professor Nagaty publicou mais de 40 artigos sobre diferentes assuntos, incluindo computa\u00e7\u00e3o em nuvem, biometria, bioinform\u00e1tica, esteganografia, processamento de imagens e com\u00e9rcio eletr\u00f4nico. Ele \u00e9 revisor em muitas revistas cient\u00edficas e confer\u00eancias internacionais que incluem: IET Biometrics, IEEE Transactions on Cloud Computing, IEEE Transactions on Signal Processing, e muito mais. Seu doutorado em ci\u00eancia da computa\u00e7\u00e3o foi publicado na forma de livro impresso por Lap Lambert na Alemanha, 2012. Ele supervisionou teses de mestrado nos campos de reconhecimento facial, recupera\u00e7\u00e3o de imagem de base de conte\u00fado, racioc\u00ednio de base de caso, algoritmos gen\u00e9ticos e esteganografia de DNA. Atualmente ele \u00e9 professor permanente no BUE no Egito.<\/p>","protected":false},"excerpt":{"rendered":"
