The term Hylemetry is the composition of the two Greek words Hyle and Metros. For Aristotle the term ὕλη (hyle) meant non-living matter; therefore, the hylemetric authentication may identify the procedure for the identification of an inanimate object. Since biometric identification has given excellent results, it comes naturally to apply similar criteria to uniquely identify “non-living matter”, as for instance banknotes. The term Hylemetry was invented by G. Schirripa Spagnolo in 2008. It was used for the first time in international context in the 2010 referring to the usage of Hylemetry for banknote authentication by G. Schirripa Spagnolo, L. Cozzella and C. Simonetti. ==Process== The hylemetric approach is based, as for biometry, in the identification of a unique random characteristic, used to create a template, which can uniquely identifying the object. In theory, every random and irreproducible characteristic could be used in hylemetric identification. However, a valid feature also needs the following properties: * uniqueness, which indicates that no two objects should be the same in terms of the characteristic, * permanence, which means that the characteristic should be invariant with time, * collectability, which indicates that the characteristic can be measured quantitatively, * non-invasive, which indicates that the characteristics can be measured without modifying anything. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hylemetry」の詳細全文を読む スポンサード リンク
