Abstract
The present invention relates to a method of authenticating and/or identifying an article containing a chemical marking agent, which is substantially inseparably enclosed in a marker as a carrier and contains selected chemical elements and/or compounds in the form of marker elements, in concentrations based on a predetermined encryption code, which method comprises the steps of: i) qualitatively and/or quantitatively identifying the marker elements of the chemical marking agent, and ii) comparing the values identified in step (i) with the predetermined encryption code.
Claims15
A method of authenticating and/or identifying an article containing a chemical marking agent, which is substantially inseparably enclosed in a marker as a carrier and contains selected chemical elements and/or compounds, so-called marker elements, in concentrations according to a predetermined encryption code, which method comprises the steps of:
- i) qualitatively and/or quantitatively identifying the marker elements of the chemical marking agent, and
- ii) comparing the values identified in step (i) with the predetermined encryption code.
