Synchronization in a file storage system using authentication-state-based permissions

Abstract:

A system is provided for facilitating access to data stored in a cloud-based storage service. Data associated with a user account is stored at the cloud-based storage service. A portion of the data is associated with a heightened authentication protocol. A request for an application to receive data that is associated with the heightened authentication protocol is received at the cloud-based storage service. In response to the request, the request is authenticated based on the heightened authentication protocol. In response to authenticating the request, permission is granted for the application to receive the data that is associated with the heightened authentication protocol. In response to a locking of the data that is associated with the heightened authentication protocol, an indication that the data is unavailable is sent to the application.
