This paper describes a novel method of detecting the presence of a special substance which posesses certain electromagnetic qualities, for identification and authentication purposes, while dealing with the issue of varying concentration levels of the substance. It should be noted that the concentration level itself may be used as a means of identification, in addition to the electromagnetic response of the susbstance. The substance is usually incorporated into an ink, which is then used to print a mark onto the object which bears identification.
