Abstract: Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. A consequence of such restrictions may be that a process will not be able to do in the background state, what it may be able to do if it were in the foreground state. Implementation of the disclosed services may be substantially transparent to the executing user applications and, in some cases, may be performed without the user application's explicit cooperation

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for wireless data protection utilizing cryptographic key management on a primary device and a backup device. A system encrypts a file with a file key and encrypts the file key twice, resulting in two encrypted file keys. The system encrypts each file key differently and stores a first file key on the primary device and transmits one of the encrypted file keys in addition to the encrypted file to a backup device for storage. On the backup device, the system associates the encrypted file key with a set of backup keys protected by a user password. In one embodiment, the system generates an initialization vector for use in cryptographic operations based on a file key. In another embodiment, the system manages cryptographic keys on a backup device during a user password change.

Abstract translation: 提供个人电子设备的服务，支持后台处理或多任务的形式。 所公开的服务允许用户应用程序利用后台处理，而不会对用户对前台进程或个人电子设备的电源资源的体验产生显着的负面影响。 为了实现所公开的多任务，可以执行一些或多个操作限制。 这种限制的结果可能是一个进程将无法在后台状态下执行，如果它处于前台状态，那么它可以做些什么。 所公开的服务的实现对于执行的用户应用程序可能是基本透明的，并且在一些情况下可以在没有用户应用程序的明确协作的情况下执行
