Ink verification detection method and system for label anti-counterfeiting

Abstract

This invention discloses an ink verification and detection method and system for label anti-counterfeiting, relating to the field of anti-counterfeiting verification. The method includes: forming an ink pattern on a label substrate, with the ink response component characteristics exhibiting preset changes, constituting a spatial distribution coding physical carrier; a verification device switching between low-frequency and high-frequency response modes, applying an excitation signal to the ink pattern and performing trajectory scanning to obtain an original signal sequence containing response signal intensity and spectral characteristics; correcting temporal distortion of the original signal sequence, identifying the spatial phase distribution of signal characteristics, and performing multi-dimensional detection feature parameter conversion based on a detection lookup table; measuring single-point and cumulative differences through template matching, and outputting the verification result; and managing the verification result at the terminal. This application solves the technical problem of insufficient anti-counterfeiting capability due to the single detection dimension in existing anti-counterfeiting verification methods, achieving the technical effect of improving the multi-dimensional comprehensive discrimination capability of anti-counterfeiting verification.
