Abstract

The invention provides an individual identification apparatus and an individual identification method based on oscillometric arterial blood pressure measurement. The individual identification apparatus comprises a pressure detection sensor part for detecting the balloon pressure with pulse wave effect included; a pulse wave extraction part for extracting arterial pulse wave signals from the cuff balloon pressure detected by the pressure detection sensor part; a pulse wave amplitude detection part for dividing the pulse wave signals extracted by the pulse wave extraction portion into a plurality of window areas and detecting maximum amplitude pulses and minimum amplitude pulses in each window area; a pulse wave image generation part for generating personalized pulse wave images by using the maxim amplitude pulses and the minimum amplitude pulses in each window area detected by the pulse wave amplitude detection part; and a bioinformation storage part for storing the personalized pulse wave images generated by the pulse wave image generation part.

Description

technical field [0001] The invention relates to an individual identification device and method for measuring arterial blood pressure based on an oscillometric method. More specifically, it relates to an individual based on the principle of oscillometric arterial blood pressure measurement by using the maximum and minimum amplitude values ​​detected from pulse wave signals corresponding to a plurality of window intervals to generate a pulse wave image capable of identifying an individual. Identification device and method. Background technique [0002] At present, technology development through universal biometric technologies such as fingerprints, complexion, and iris attributes occupies the mainstream. However, these individual identification technologies based on biometric technology cannot completely eliminate forgery and imitation. For example: fingerprints can be replicated with latex, and irises can be faked with artificial contact lenses that replicate their features...
