Abstract
"MéTODO E SISTEMA PARA RECUPERAçãO DE DADOS PRIVADOS PROTEGIDOS POR SENHA VIA UMA REDE DE COMUNICAçãO SEM EXPOSIçãO DOS DADOS PRIVADOS". Trata-se de um sistema e método para utilizar o serviço de roaming de forma segura dados privados a partir de um primeiro computador de cliente até um segundo computador de cliente ligado através de uma rede de comunicação. Um usuário do primeiro computador de cliente executa um aplicativo de cliente doméstico e designa dados privados para utilizar o serviço de roaming. O aplicativo de cliente doméstico gera uma primeira chave em resposta a uma senha, e criptografa os dados privados designados como uma função da primeira chave. O servidor recebe e armazena os dados privados criptografados. Um usuário do segundo computador executa um aplicativo de cliente em viagem com serviço de roaming e solicita a transferência dos dados privados criptografados a partir do servidor. O aplicativo de cliente em viagem com serviço de roaming gera a primeira chave em resposta à senha, e decriptografa dados privados criptografados transferidos a partir do servidor para obter os dados privados. A invenção proporciona adicionalmente aos usuários a capacidade de recuperar dados privados criptografados a partir do servidor mesmo quando o usuário não lembra a senha associada com a primeira chave. Também, o servidor não tem conhecimento dos dados privados nem das chaves.
