Abstract
MÉTODO E SISTEMA DE AUTENTICAÇÃO DE UMA MARCAÇÃO APLICADA EM UM SUBSTRATO E QUE TEM UMA COMPOSIÇÃO QUE COMPREENDE UM PRIMEIRO MATERIAL QUE INCLUI UMA ETIQUETA SERS, OU UMA ETIQUETA SERRS. A invenção se refere a um método, e um sistema correspondente, capaz de verificar se etiquetas SERS ou SERRS genuínas que têm um recurso de espalhamento de aprimoramento de superfície característico exclusivo estão presentes ou não em uma marcação legível por máquina aplicada em um documento de valor ao usar um espectrômetro de Raman adaptado para realizar uma análise de Espectroscopia de Raman da marcação. O método de acordo com a invenção permite uma detecção confiável e rápida de uma presença das etiquetas SERS/SERRS, e é particularmente adequado para verificar a autenticidade de documentos de valor, por exemplo, como cédulas bancárias, que se movem em relação ao espectrômetro de Raman com uma dada velocidade, e possivelmente com uma alta velocidade, ou brevemente expostos ao espectrômetro de Raman.
