Cover Story: Identification and authentication of printed documents is a critical issue for security purposes. The manufacturing process to engender common paper sheets involves wood particles useful to individuate unique features; in fact, their random disposition makes a single sheet almost unique, giving the possibility, under certain conditions, to extract a fingerprint from the generated pattern. In this paper, a method to generate a robust fingerprint for document identification based on binary patterns was proposed; it also includes a PCA-based and block-division fingerprint reduction strategy, a low-cost framework for digital pattern acquisition and a public dataset of images acquired with both low-cost and high devices. Comparison with the state of the art confirmed the goodness of the method. View this paper.
