Abstract
"MéTODO E SISTEMA PARA A OBTENçãO DE ASSINATURAS DIGITAIS". Trata-se de um sistema de assinatura digital que inclui uma base de dados que detém regras de controle de acesso que identificam documentos autorizados para os quais os usuários têm permissão para ser assinados eletronicamente e um sistema de assinatura capaz de receber solicitações de assinatura a partir de uma pluralidade de usuários autorizados, sendo que cada solicitação de assinatura inclui um documento a ser assinado, em que o sistema de assinatura analisa o documento a ser assinado e compara as informações obtidas desta maneira com as regras de controle de acesso armazenadas na base de dados para determinar se o usuário autorizado está autorizado a ter o documento assinado, e em que caso se determine que o usuário autorizado está autorizado a ter o documento assinado, o sistema de assinatura assina o documento usando informações de autenticação únicas do sistema de assinatura.
