The invention refers to a method, device and security system, all for authenticating a marking (M-P), comprising the steps of: exciting said luminescent probe marking (M-P) with at least one excitation pulse (P) of at least one excitation source (3, 31-36), measuring probe intensity values (VP1-VPn) of emission intensity (I) from emission radiation (E) of said luminescent probe marking (M-P) in response to said at least one excitation pulse (P) at time intervals (t1-tn), forming a probe intensity-versus-time emission function of said probe intensity values (VP1-VPn), comparing said probe intensity-versus-time emission function with at least one reference intensity-versus-time emission function, said probe intensity-versus-time emission function and said reference intensity-versus-time emission function are normalized prior to comparison. |
