Title:
なりすまし検知装置
Document Type and Number:
Japanese Patent JP4910627
Kind Code:
B2
Abstract:
To provide a technology for detecting impersonation with a photograph or the like by simple processing without causing the enlargement of a device and degradation of convenience.
At the substantially same timing as an in-camera 12 photographing a first image used for user authentication, an out-camera 13 photographs a second image. An impersonation detection device determines whether impersonation is performed when photographing the first image by analyzing the second image. The detector determines that impersonation is performed when a face is included in the second image, for instance.
