I will talk about a new paper fingerprinting technique based on analyzing the patterns revealed when light is shone through the paper. These patterns represent the inherent texture of paper, formed by the irregular interleaving of wooden particles during the manufacturing process. We show these patterns can be easily captured by a commodity camera and condensed into to a compact 2048-bit fingerprint code. Through experiments, we demonstrate that the embedded paper texture provides a more reliable source for fingerprinting than features on the surface used by previous works. We show that using our method any two sheets of paper can be reliably distinguished. Based on the collected datasets, we achieve false rejection and false acceptance rates of less than 0.1%. We further report that our extracted fingerprints contain 807 degrees-of-freedom (DoF), which makes our method highly scalable for recognition among very large databases.
