Abstract

métodos para gerar uma base de decomposição e para extrair uma assinatura aleatória de um elemento de material objeto, dispositivo, e, programa de computador a presente invenção diz respeito a um método para extrair uma assinatura aleatória de um elemento de material objeto, compreendendo: uma fase para gerar pelo menos um vetor de aquisição das características estruturais de pelo menos uma região do elemento de material objeto, uma fase para gerar pelo menos um vetor de assinatura aleatória a partir do vetor de aquisição, o vetor de assinatura aleatória compreendendo: pelo menos um componente aleatório tendo uma natureza estável, de modo que seu valor possa ser encontrado em cada implementação do método sobre a mesmaregião do elemento de material objeto, e/ou pelo menos um componente aleatório tendo uma natureza instável, de modo que seu valor seja provável de variar de modo aleatório em cada implementação do método sobre a mesma região do elemento de material objeto, o uso do vetor de assinatura aleatória como assinatura aleatória.
