BIOMETRIC INFORMATION MEASUREMENT DEVICE, INDIVIDUAL IDENTIFICATION DEVICE, INDIVIDUAL IDENTIFICATION METHOD, AND INDIVIDUAL IDENTIFICATION PROGRAM

摘要

Provided are: a biometric information measurement device, an individual identification device, an individual identification method, and an individual identification program, which enable easy authentication of an individual at a low cost, regardless of the individual's physical condition. A biometric information measurement device 100 is provided with: a pressure sensor 10 including a plurality of pressure detection elements 12 aligned in one direction; a pressing mechanism 20 for pressing the pressure sensor 10 with respect to the wrist in a state in which the one direction crosses the extending direction of the radial artery TD under the skin of the wrist of a person on which measurement is to be performed; and a control unit 30 for judging whether or not the person on which measurement is to be performed is a registered user, on the basis of data showing the relationship between the position of each of the pressure detection elements 12 in the one direction and an absolute value of a pressure signal detected by each of the pressure detection elements 12 in a pressed state in which the pressure sensors 10 are pressed against the wrist by the pressing mechanism 20.
