Apple is apparently ramping up its battle to prevent iPhone and iPod owners from jailbreaking their devices.

The company has applied for a patent, titled "Systems and Methods for Identifying Unauthorized Users of an Electronic Device," that covers a series of security measures to automatically protect devices from thieves and other "unauthorized users." Unauthorized users apparently applies to those who engage in jailbreaking, which allows devices to run apps not approved by the company producing the operating system--such as Apple, the main target of such bypasses.

The application, which was filed in February 2009 and published Thursday, describes measures to identify "particular activities that may indicate suspicious behavior," so that "safety measures" can be taken to restrict the device's functions. Those activities include the "hacking, jailbreaking, unlocking, or removal of a SIM card," according to the application. Apple also intends to send warnings to owners via e-mail or text message when such activity is detected.

The application also describes a variety of measures that could be used to help identify the unauthorized user, including the activation of a camera that could capture and geotag the device's surroundings, and perhaps current user, and transmit that information to a remote device:
