Abstract

De acuerdo con un aspecto de la invención, un archivo recibido de un primer usuario se almacena en un dispositivo de almacenamiento, donde el archivo incluye metadatos privados codificados criptográficamente por una clave secreta asociada con un segundo usuario. Un identificador de metadatos privados se almacena en una ubicación de almacenamiento predeterminada, lo que indica que los metadatos privados del archivo no se han descodificado criptográficamente e indizado. En respuesta a una consulta recibida subsecuentemente del segundo usuario, la ubicación de almacenamiento predeterminada se explora para identificar el identificador de metadatos privados con base en la consulta. Los metadatos codificados criptográficamente, identificados por el identificador de metadatos privados, se transmiten al segundo usuario para su descodificación criptográfica. En respuesta a los metadatos que se han descodificado criptográficamente por el segundo usuario, los metadatos descodificados criptográficamente se indizan para el propósito de búsquedas subsecuentes de por lo menos uno de los metadatos y el archivo.
