A proposal for a text-indicated writer verification method

Abstract

We propose an on-line writer verification method to improve the reliability of verifying a specific system user. In the proposed method, a different text including ordinary characters is used on every verification process. This text can be selected automatically by the verification system so as to reflect the specific writer's features. A specific writer is accepted only when the same text, which is indicated by the verification system, is written, and the system can verify the writer's personal features from the written text. The proposed method makes it more difficult to disguise writer himself with forged handwriting data than the previous methods using only signatures.
