摘要：Online signature verification is one of the biometric features which can be used for identity in the financial transaction, contract document, as well as being used to authenticate the materials.In this paper, we present a system using Dynamic Time Wrapping (DTW) and extended regression to verify the online signatures. Our system will extract 20 features in each points of the signature, andthe system will standardize these features before they enter into the system for training or testing.When conducting authentication, a user's signature is considered to be correct when the similarity measure calculated by using DTW and extendedregressionisusedtocalculatethesimilarityindexofthetwos ignaturesis greater than a threshold.The validity of the proposed method was tested on the public SVC2004 signature database.
