Abstract

"método para implementar um sistema para autenticação de um artigo, e, sistema para autenticação de um artigo" é descrito um método para implementar um sistema para autenticação de um artigo com base na assinatura gerada a partir de um conjunto compreendendo grupos de pontos de dados coletados quando uma pluralidade de regiões de uma estrutura de superfície intrínseca de um artigo são sequencialmente submetidas a luz coerente e a luz dispersa pela estrutura de superfície intrínseca é coletada. para uma dada implementação de sistema, o método compreende: determinar um conjunto de parâmetros que influência o desempenho do sistema; determinar uma definição de desempenho do sistema que pode ser afetada pelo conjunto de parâmetros; produzir uma população inicial de conjunto de valores de parâmetro, cada conjunto de parâmetro incluindo um valor para cada parâmetro a ser usado em alcançar um desempenho desejado do sistema; determinar para cada conjunto de valores de parâmetros um valor de conveniência em termos da definição de desempenho do sistema; identificar pares correspondentes da população de acordo com as conveniências determinadas; produzindo uma nova população cruzando os pares correspondentes; repetindo a determinação de um valor de conveniência para cada conjunto de valores de parâmetro, identificando os pares correspondentes e produzindo uma nova população até um critério final ser satisfeito; e configurar o sistema de acordo com um selecionado um dos conjuntos de parâmetros a partir da população final. e por meio disso, uma abordagem flixível e apropriada para implementação de sistema pode se seguida que fornece alta eficiência em termos da introdução do tempo humano e que fornece valores de parâmetro de configuraçaõ de alta qualidade confiáveis para permitir resultar em uma implementação de sistema eficiente e confiável.
