Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for erasing user data stored in a file system. The method includes destroying all key bags containing encryption keys on a device having a file system encrypted on a per file and per class basis, erasing and rebuilding at least part of the file system associated with user data, and creating a new default key bag containing encryption keys. Also disclosed herein is a method of erasing user data stored in a remote file system encrypted on a per file and per class basis. The method includes transmitting obliteration instructions to a remote device, which cause the remote device to destroy all key bags containing encryption keys on the remote device, erase and rebuild at least part of the file system associated with user data, and create on the remote device a new default key bag containing encryption keys.

Abstract: Improved techniques and apparatus for managing data between a host device (e.g., host computer) and a client device. The data being managed can, for example, pertain to portable computer programs, such as widgets. The managing of the data thus can involve transfer of portable computer programs (e.g., widgets) between the host device and the client device. In one embodiment, the transfer of portable computer programs between a host device and a client device can be referred to as synchronization.
