Abstract

SISTEMA E MéTODO PARA EMBUTIR MARCAS DE SEGURANçA EM MINIATURA DISPERSAS. A presente invenção refere-se a um método para embutir marcas de segurança em miniatura dispersas dentro de documentos e imagens, utilizando uma base de parâmetros de marca, uma interface gráfica com o usuário, e um simulador de detecção. O método inclui prognosticar taxas de erro de detecção para cada localização de pixel de uma imagem hospedeira, definida como uma representação digital de pelo menos um receptor das marcas de segurança em miniatura dispersas, com cada marca de segurança em miniatura dispersa incluindo vários pontos espalhados. As taxas de erro de detecção para cada pixel são exibidas com a imagem hospedeira em uma interface gráfica com o usuário e são selecionadas as localizações desejadas de marca de segurança em miniatura dispersa. Pelo menos um conjunto de parâmetros de marca de segurança em miniatura dispersa é identificado, com os parâmetros sendo parâmetros de marca que permitem a determinação de um equilíbrio otimizado entre a capacidade de detecção e a visibilidade das marcas de segurança em miniatura dispersas. A imagem hospedeira com a marca de segurança em miniatura dispersa é exibida para inspeção e ajuste por um operador.
