Biometric feature attack objects and biometric feature attack test systems

A system for performing biometric feature attack tests, wherein the system comprises:

• a biometric feature attack object, comprising a substrate, a biometric feature attachment part, and a conductive part, wherein:
• the substrate comprises a biometric feature carrying area and a pressing area, and the biometric feature carrying area and the pressing area are respectively disposed on two opposite sides of the substrate;
• the biometric feature attachment part is disposed in the biometric feature carrying area, wherein the biometric feature attack object further comprises an identity identifier, wherein the identity identifier is located on a side of the substrate on which the pressing area is located and in an area different from the pressing area, and wherein the identity identifier and the pressing area are used to define a placement position of the biometric feature attack object;
• and
• the conductive part is disposed in the pressing area or the biometric feature carrying area;
• wherein the pressing area comprises a first central point, the identity identifier comprises a second central point, and the placement position of the biometric feature attack object is defined by pose information of a line connecting the first central point and the second central point.
