Abstract

A invenção refere-se a um método para intensificação do nível de segurança contra adulteração e contrafação de um objeto compreendendo a preparação de um desenho determinístico original e a sua marcação a laser na superfície de um objeto, materializando-se um objeto marcado original; a captação de uma ou mais imagens do desenho determinístico marcado original e a associação de informações a essa imagem, armazenando-as numa base de dados; a captação de pelo menos uma imagem de um desenho determinístico marcado a validar num objeto marcado a validar e o cálculo de descritores dessa imagem; a validação e a decisão sobre a autenticidade do objeto marcado a validar. A invenção refere-se ao objeto marcado original e ao seu método de preparação. A invenção compreende aparelhos computacionais, programas de computador, meios de leitura e aparatos para preparação adaptados. A invenção cria marcas de autenticação únicas e não clonáveis, aplicáveis a objetos.
