Abstract

A invenção compreende a materialização de um objeto original (1) com nível de segurança intensificado com base no processamento de uma imagem original (3) e de um marcador digital com informação codificada da imagem original (5). A invenção compreende um método para validação de um objeto a validar (2) possuindo uma imagem a validar (4) e um marcador digital a validar (6), que compara informações codificadas calculadas a partir de pelo menos uma imagem a validar (4) com informações codificadas correspondentes a pelo menos uma imagem original (3), por meio do processamento das informações codificadas presentes em pelo menos um marcador digital a validar (6). A invenção compreende aparelhos computacionais, programas de computador e meios de leitura por um aparelho computacional adaptados. A invenção visa criar mecanismos e instrumentos de controlo de autenticidade de objetos no campo técnico da gráfica de segurança.
