1. A computer-implemented method for material identification, comprising:
generating a plurality of first fingerprints for a plurality of material sheets supplied by a supplier at a first step of processing the plurality of material sheets, wherein each first fingerprint in the plurality of first fingerprints represents a first attenuation measurement of each material sheet in the plurality of material sheets and captured by an array of transducers;
generating a batch mask relating to the first step of processing the plurality of material sheets and based on the plurality of first fingerprints, wherein the batch mask represents a signal correlation of the plurality of first fingerprints that is unique to the plurality of material sheets supplied by the supplier;
identifying a target material using the batch mask; and
generating a plurality of second fingerprints for the plurality of material sheets at a second step of processing the plurality of material sheets, wherein each second fingerprint in the plurality of second fingerprints represents a second attenuation measurement of each material sheet in the plurality of material sheets and captured by the array of transducers, wherein the second step of processing includes stamping each material sheet into an automotive component, and the second fingerprint of each material sheet represents an attenuation measurement of the automotive component.
