A feasibility experiment on an automatic signature verification system based on writing pressure was conducted using a new device sensing the z-axis component of writing pressure. The data acquisitions were conducted over a half a year for checking both subjects' and device stabilities. The DP (dynamic programming) matching method provided 6% error rates for type I and type II errors. The nature of signature writing pressure was investigated.
