Abstract:
A method with access authority management includes: receiving an input image comprising a region of at least one portion of a body of a user; determining whether the user corresponds to multiple users or a single user using the region of the at least one portion of the body; performing a verification for the user based on a face region in the input image, in response to the determination that the user is the single user; determining whether the input image is a real image or a spoofed image based on whether the verification is successful; and allowing an access authority to a system to the user, in response to the determination that the input image is the real image.

Abstract:
A method implemented using a device to measure hemodynamic parameters is provided. The method includes transmitting, by the client device, a message to the server. The method includes capturing, by a camera, a first image of a plurality of images of a target region while two light emitting diode (LED) sensors emit light, via a collimated lens, on the target region. The method also includes capturing, by the camera, a second image of the plurality of images of the target region while the two LED sensors emit light, via the collimated lens, on the target region. The second image is captured a predetermined time after the first image is captured. The method further includes determining one or more hemodynamic parameters based on a difference between the first captured image and the second captured image.
Abstract:
A method implemented by a device to measure a bodily parameter includes transmitting, by a transmit (Tx) antenna of an antenna pair, a first radar pulse to a receive (Rx) antenna of the antenna pair. The method also includes receiving, by the receive (Rx) antenna, the first radar pulse. The first radar pulse travels through a radar target between the Tx antenna and the Rx antenna. The method further includes transmitting, by the Tx antenna, a second radar pulse to the Rx antenna. In addition the method includes receiving, by the Rx antenna, the second radar pulse, wherein the second radar pulse travels through the radar target between the Tx antenna and the Rx antenna. The method also includes determining a bodily parameter within the radar target as a function of the transmission and the reception of the first radar pulse and the second radar pulse.
