Abstract

métodos para processamento de metadados privados. de acordo com um aspecto da invenção, um arquivo recebido a partir de um primeiro usuário é armazenado em um dispositivo de armazenamento, em que o arquivo inclui metadados privados criptografados por uma chave de segredo associada a um segundo usuário. um identificador de metadados privados é armazenado predeterminado, indicando que os metadados privados do arquivo não foram descriptografados e indexados. em resposta a uma consulta subsequentemente recebida a partir do segundo usuário, o local de armazenamento predeterminado é varrido para identificar o identificador de metadados privados com base na consulta. os metadados criptografados identificados pelo identificador de metadados privados são transmitidos para o segundo usuário para descriptografia. em resposta aos metadados que foram descriptografados pelo segundo usuário, os metadados descriptografados são indexados com o propósito de pesquisas subsequentes de pelo menos um dentre os metadados e o arquivo.
