Title: VITAL SIGN INFORMATION DETERMINATION METHOD, IDENTITY AUTHENTICATION METHOD AND DEVICE
Abstract:
An embodiment of the present application provides a vital sign information determination method, identity authentication method and device. The vital sign information determination method comprises: obtaining first biometric data acquired when an object to be measured presses on a biometric sensor, wherein the first biometric data is used to reflect body surface texture features of the object to be measured; parsing multiple pieces of first biometric data of the object to be measured to obtain second biometric data, wherein the second biometric data is used to reflect vital signs of a main body of the object to be measured; and determining vital sign information of the main body of the object to be measured according to the second biometric data. The identification of the vital sign information can be realized by conveniently using the same biometric sensor without changing the structure of the existing biometric sensors and without adding additional in vivo identification sensors, avoiding the issue of the prior art of high production costs resulting from the requirement to increase in vivo identification sensors when an in vivo identification function is added, and further realizing identity authentication based on in vivo identification.
