Abstract

a invenção se refere a um método para determinar uma impressão relacional entre duas imagens, compreendendo as seguintes etapas: a implementação de uma primeira e de uma segunda imagens; uma fase de cálculo de vetores de semelhança entre blocos pertencentes às primeira e segunda imagens, respectivamente, com os vetores de semelhança formando um campo de vetores de impressão, tal campo de vetores de impressão compreendendo pelo menos uma região aleatória desordenada no sentido de um critério de entropia; uma fase de gravação, como uma impressão relacional, de uma representação do campo calculado de vetores de impressão. o invento também se refere a um método para autenticar uma imagem candidata em relação a uma imagem autêntica, implementando o método para determinar uma impressão relacional de acordo com a invenção.
