The method includes, detecting, by an imaging device, the presence of an object to be imaged. The method further CN includes, measuring, by the imaging device, a first characteristic of the object to be imaged, and measuring, by the imaging device, a C second characteristic of the object to be imaged. The method further includes, determining, by a computing device, that at least one ---- of the first characteristic of the object or the second characteristic of the object exceeds a threshold; W D indicating, by the computing device, whether the object to be imaged is one of a spoofed object or an actual object. 1-1 0 ei and in response to determining, O [Continued on next page] WO 2018/009568 Al MIDEDIM01101 DIDIIMEN111111111111111111111111110111101111111111111111111 EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, SK, SM, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
