Document Type and Number:
WIPO Patent Application WO/2021/006260
Kind Code:
A1
Abstract:
According to an authentication system (10), a wireless tag (T) stores a first face feature point that is a face feature point extracted from a captured image of the face of a user. The authentication system (10) is provided with an authentication device (20). In this authentication device (20), information can be read/written wirelessly through a wireless communication unit (22) with respect to the wireless tag. In the authentication device (20), a wireless communication condition of the wireless communication unit (22) is adjusted by a controller (21), and the position of the wireless tag (T) is estimated on the basis of a distance to the wireless tag (T) detected in accordance with a response wave from the wireless tag (T). In addition, the imaging condition of an imaging unit (23) is adjusted. The position of the user is detected in accordance with the imaging result of the imaging unit (23). From the face image of the user captured by the imaging unit (23), a face feature point is extracted as a second face feature point, and a comparison is made between the extracted second face feature point and the first face feature point read from the wireless tag (T) by the wireless communication unit (23). On the basis of this comparison result, authentication of the user is performed.
