1. A method of authorization comprising:
- receiving an infrared input signal via a sensor array located in an integrated sensing area of a display interface of a device,wherein the sensor array comprises a pyroelectric, or a pyroelectric and piezoelectric, based material integrated in the display interface of the device;
the infrared input signal being caused by a user surface interaction when the user places a finger or ear on, or in close proximity to, the integrated sensing area of the display interface of the device,converting, by the sensor array, the infrared input signal to an electrical signal;
analyzing the electrical signal; and
biometrically authorizing the user based on the analyzing,unlocking the device based on the biometric authorization,continuously analyzing and biometrically authorizing the user based on the user'"'"'s surface interaction on the integrated sensing area of the display interface of the device while the device is unlocked,detecting the removal of the user surface interaction on the integrated sensing area of the display interface of the device, andlocking the device based on the removal of the users surface interaction on the integrated sensing area of the display interface of the device;
wherein the step of analyzing comprises compiling an image mapping of thermal differences induced by the user surface interaction made by the user with respect to the display interface.
