[PROBLEMS] To prevent drunk driving more efficiently and reliably by taking into account acetaldehyde and internal substances that induce fatigue, not just by measuring alcohol concentration in blood, but also preventing drunk driving. In addition, a lightweight, small and inexpensive drinking detection device is provided. A biological information acquisition unit 4 that acquires biological information of a subject as authentication information, and an operation of the biological information acquisition unit 4 is interlocked. The measurement unit 1 that selectively measures the infrared spectral absorptance of a part of the subject's body with respect to a specific wavelength and acquires the inspected information, and the information storage that stores the registered biological information and the reference absorptivity The comparison unit 8 compares the registered biometric information with the information to be authenticated, authenticates the person as the specific driver, compares the reference light absorption rate with the information to be inspected at a specific wavelength, and performs the specific operation. Person's drunk state Determining and a determination section 10. [Selection] Figure 1 |
