Embodiment 1
[0062] In the method for establishing, analyzing, and confirming the identity information of an item in this embodiment, first, an element information unit can be set on the item, and the composition of the element information unit includes the item element that constitutes the item itself, and the setting elements that are additionally set on it. In the invention, the combination of the item element and the setting element used is used as the element information unit of the item. The setting element can be added in a variety of ways, for example: it can be added during the production process of the item (for example: added in the process of processing plastic products) ), can also be combined with the article or the packaging of the article by physical and / or chemical means such as smearing, spraying, soaking, stirring, plating, inlaying, deposition, injection, infiltration, mixing and / or printing, and then detected by X-ray fluorescence The element information unit is detecte...
Embodiment 2
[0071] Other conditions are the same as in Example 1, except that the amount of spectral data detected in the above example will be very large (as shown in Figure 2), and, even for the same article, different individuals will have a large number of samples due to differences in the manufacturing process or raw materials. On a certain part, its composition may also be different, so if the complete standard spectral data measured in advance is compared with the complete detection spectral data obtained by detection, the calculation speed will be very slow, so this example further optimizes it .
[0072] In this embodiment, in order to speed up the analysis speed of the detected data and ensure the accuracy, the spectral data obtained in Embodiment 1 is used as the standard data, and the fingerprint data is obtained through manual selection and / or calculation for selective reading. The established standard data is selected according to the content and ratio of elements and elemen...
