In a patent software titled “User Identification Using Headphones,” filed with the United States Patent and Trademark Office and noticed by Patently Apple, Apple explains the way it can authenticate AirPods customers utilizing different close by units, ultrasonic indicators, voice recognition, and even a wearer’s gait.

The submitting seeks to tackle the problem of AirPods being unable to decide whether or not a wearer is the approved consumer of a related system. Apple means that this generally is a drawback since any consumer can place headphones into their ear whereas they’re related to a tool belonging to one other particular person, which dangers the related system releasing private data, equivalent to by way of notifications introduced by Siri.

The system is ready to bypass the necessity for Face ID, Touch ID, or another form of biometric authentication on a separate system, as an alternative utilizing a “similarity score” to confirm a consumer’s id. This similarity rating could also be based mostly on a number of variables, such because the proximity of different close by units belonging to the related system’s proprietor. Nevertheless, Apple says that biometrics may nonetheless be used to enhance the accuracy of the similarity rating. To authenticate a consumer based mostly on biometrics with AirPods themselves, Apple proposes enjoying and receiving ultrasonic sounds contained in the headphones:

For instance, varied traits of the consumer’s ear present an echo of the ultrasonic sign which is exclusive to the consumer. Variations within the floor of the consumer’s ear canal could trigger the ultrasonic sign to mirror off the floor and generate an echo having a signature that’s related to the consumer. For instance, a consumer having a bigger ear canal could end in an echo having an extended reverberation time than a consumer having a smaller ear canal.

Apple provides that AirPods may additionally use data gathered a few consumer’s gait and voice from the AirPods’ gyroscopes, accelerometers, and microphones to decide if they’re the proprietor of the related system. Collectively, these varied information factors present an total similarity rating that would authenticate customers if it reaches the required threshold.

Apple typically provides new options to present AirPods units utilizing firmware updates, equivalent to assist for the Find My community, Conversation Boost, and Spatial Audio, so appears it believable that AirPods consumer authentication may theoretically be added in a future replace. Patent filings usually are not consultant of Apple’s speedy plans, however they do present among the firm’s particular areas of analysis and growth.

Other latest Apple patent filings included designs for all-glass iPhones and Apple Watches, a removable MacBook key that works as a mouse, and a hydration sensor for the Apple Watch.
