Abstract

"PROJETOR QUE PROJETA SENHA". Trata-se de um projetor conectável em rede com um aparelho de terminal de informação e capaz de aperfeiçoar a facilidade de utilização pelo usuário e garantir sigilo dos dados de comunicação. Um projetor (10) é conectado em rede a um computador pessoal (PC), constituindo dessa forma um sistema de projeção. No projetor (10), uma senha exigida para estabelecer uma conexão de rede é gerada e projetada em uma tela (SC). No computador pessoal (PC), um usuário vê a senha projetada na tela (SC) e introduz a mesma. O projetor (10) e o computador pessoal (PC) realizam autenticação de conexão e comunicação codificada mediante uso da senha.
