Abstract
Provided is a method for verifying the veracity of a finger by a verification device including a projection device projecting a pattern of parallel lines orthogonal to the longitudinal direction of the finger, a capture device capturing an image of the finger and of the pattern, and a processing unit. The method includes: an illumination step in which the projection device illuminates the finger with the pattern; a contactless capture step in which the capture device captures a pattern image of the projected pattern; a fringe-extraction step in which the processing unit extracts fringes from the pattern image; a feature-calculation step in which the processing unit calculates a feature relating to the physical structure of the fringes; a comparison step during which the processing unit compares the calculated feature with reference values; and a decision-making step in which the processing unit makes a decision regarding the veracity of the finger.
