Currently, Apple allows users to enter up to five different fingerprints to unlock an iPhone, so users would just have to designate which is the "emergency" print in the Touch ID settings menu. Apple's patent describes a situation in which a thief attempts to rob someone's iPhone from them to gain access to their personal and private data stored within, and the user being robbed quickly placing the panic mode finger on Touch ID so the thief can't access any data.
The company is going one step further with the patent application, however, describing a way in which the activation of panic mode turns on the iPhone's camera and microphone to capture a robbery or crime as it happens and sending all the data to both a user's iCloud account and possibly even local police. Another section of the patent details a possible way for the device in panic mode to act as a beacon, alerting nearby devices (other iPhones, computers, etc) to a possible crime in their vicinity so they can alert the authorities and come to the panic mode activator's aid.
In some embodiments, the mobile device 104 may be activated into the panic mode in emergency situations to act as a beacon. If there is a nearby device, the nearby other device (e.g., a PDA carried by another person, a computer in an automobile, etc.) can be alerted with an alarm so that the user of the other device might come to the aid of the user initiating the panic mode.The new patent -- inventor credit going to Karthik Sudhir -- also describes more basic functions of the feature, including a straight-forward klaxon that blares until a user confirms that they're safe and even a way for Touch ID users to set up specific apps to open immediately when they unlock the iPhone with specific fingers. As with all other patents, "panic mode" is far from confirmed and may never even make it into a future version of the iPhone, but it remains an interesting glimpse into the internal discussions at Apple regarding the company's possible future products.
For example, triggering the panic mode can send out a signal on multiple frequencies, channels, links, etc., to provide location information relative to other devices so that users of the other devices can provide assistance. Furthermore, as discussed in more detail below, the panic mode may include a locator function that uses, for example, global positioning systems (GPS) and/or cellular location systems to provide the location of the mobile device 104 to emergency response providers.
