  • Method of authentication using surface paper texture
    Patent number: 11430234
    Abstract: A method of authentication using surface paper texture includes steps of capturing a topographic pattern image of a surface of a region of interest of the paper artifact and extracting a plurality of specific features from the captured topographic pattern image. The method further identifies the location of the specific features of the paper artifact from the captured topographic pattern image. A bit map of the identified location of the specific features is generated. Then, a reference image of a reference bit map printed on the region of interest of the paper artifact is captured. Finally, the method compares the generated bit map with the captured reference bit map to generate a score. The score of the comparison determines the level of authentication. The method provides an offline method of authentication.
