Abstract

"DETECçãO DE MARCAS DE SEGURANçA DE DOCUMENTO UTILIZANDO PERFIS DE EXECUçãO". A presente invenção refere-se a um método e aparelho para impedir ou inibir a reprodução eficaz de documentos tal como dinheiro, cheques, certificados de ação e quaisquer outros documentos impressos incluindo uma marca de segurança predefinida impressa nos mesmos. O método e aparelho operam para efetuar uma revisão com múltiplas etapas de todos os dados da imagem digital adquirida de um documento impresso a ser reproduzido para propósitos de localizar quaisquer potenciais marcas de segurança e adicionalmente examinar a mesma para propósitos de positivamente identificar uma potencial marca de segurança como uma marca de segurança real. Se uma marca for localizada e verificada como sendo uma marca de segurança autentica, a reprodução eficaz do documento impresso não será permitida e/ou outras medidas de segurança serão tomadas. A velocidade do processamento é aperfeiçoada pela utilização da análise de perfil de execução para limitar os aspectos da imagem que são sujeitos à operações de associação com gabarito computacionalmente intensivas. Os perfis de execução são rastreados utilizando um autómato finito.
