New Materials for Spoofing Touch-Based Fingerprint Scanners

Goal of this article is to describe creation of several fingerprint spoofs using PCB mold but various spoof materials. The focus lays on using new materials and their modification with some additives to get better results in some sensor technologies. Process of creation and material used is thoroughly described including guidance to get better results. For every spoof there is shown resulting fingerprint and description of usage. We found that the best materials for spoof production are aquarium silicone and epoxy resin hobbyking, which are available in nearly each hobby market.
