Spoofing detection apparatus, spoofing detection method, and computer-readable recording medium

A spoofing detection performed by a spoofing detection apparatus, the method comprising:

• obtaining, from an image capture apparatus, a first image frame that includes a face of a subject person when light was emitted from a light-emitting apparatus associated with the image capture apparatus and a second image frame that includes the face of the subject person when the light-emitting apparatus was turned off;
• extracting information specifying a face portion of the subject person as first face information, from the first image frame, and extract information specifying a face portion of the subject person as second face information, from the second image frame;
• extracting a first portion that includes a bright point formed by reflection in an iris region of an eye of the subject person, from the first image frame, based on the first face information;
• extracting a second portion corresponding to the portion that includes the bright point, from the second image frame, based on the second face information;
• and
• determining spoofing of the subject person captured by the image capture apparatus, based on the first portion and the second portion.

A non-transitory computer-readable recording medium that includes a program recorded thereon, the program including instructions that cause a computer to perform:

• obtaining, from an image capture apparatus, a first image frame that includes a face of a subject person when light was emitted from a light-emitting apparatus associated with the image capture apparatus and a second image frame that includes the face of the subject person when the light-emitting apparatus was turned off;
• extracting information specifying a face portion of the subject person as first face information, from the first image frame, and extract information specifying a face portion of the subject person as second face information, from the second image frame;
• extracting a first portion that includes a bright point formed by reflection in an iris region of an eye of the subject person, from the first image frame, based on the first face information;
• extracting a second portion corresponding to the portion that includes the bright point, from the second image frame, based on the second face information;
• and
• determining spoofing of the subject person captured by the image capture apparatus, based on the first portion and the second portion.
