Abstract
A storage device provides a file system to a host based on the access rights of a user determined during authentication. If the authentication does not succeed, the storage device provides to the user a file system restricted to files authorized by public access rights. If the authentication does succeed, and the user is a device owner, the storage device provides to the user the native file system. If the authentication succeeds, and the user is not a device owner, the storage device provides a file system that is restricted to files that the given user is authorized to access. Due to the internal nature of the mechanism for safeguarding files, this security measure cannot be circumvented by simply connecting the storage device to another host that does not respect the permission rules of the file system.
