1. A method for determining authenticity, comprising: providing an object of authentication; capturing characteristic data from the object of authentication, comprising capturing an optical image of the object of authentication, comprising subjecting the object of authentication to one or more of: imaging, profilometry, polarimetry, scatterometry, and microscopy; deriving authentication data from the characteristic data of the object of authentication, comprising: performing optical characterization recognition and font reconstruction of the optical image to provide a reconstructed font; extracting from the reconstructed font one or more parameters of a polynomial spline or a Bezier curve spline representative of the reconstructed font to provide the authentication data comprising a spline font database, the authentication data comprising the spline font database corresponding to marking system data; and comparing the authentication data with an electronic database comprising reference authentication data to provide an authenticity score for the object of authentication, the reference authentication data corresponding to one or more reference objects of authentication other than the object of authentication, the reference authentication data comprising reference marking system data, the reference marking system data: corresponding to a marking system used to mark the one or more reference objects of authentication; and being derived from statistical testing of the reference authentication data, and comparing the authentication data with the electronic database comprising comparing the marking system data with the reference marking system data to provide the authenticity score for the object of authentication.
