Apple Patent Details Use of Cardiac Signals to Identify Users

A recently discovered Apple patent filing details the use of cardiac signals to recognize and authorize users on mobile devices such as the iPhone.

Once the electronic device has identified one or more characteristics of the user's heart rate, heartbeat, or other cardiac signals, the electronic device can compare the one or more identified characteristics with cardiac signal characteristics of authorized users that have been stored in memory. In response to determining that the identified characteristics correspond to those of an authorized user (e.g., match those stored in memory), the electronic device can provide the user with access to the electronic device and load the identified user's personal settings and data.

The patent is entitled, "Seamlessly Embedded Heart Rate Monitor", and was filed on January 23, 2009.
