A study on a secure communication system using biometric identity verification

摘要

This paper describes a personal key generation method based on handwriting information and its application to a telewriting system. In the proposed method, a personal key which is unique to every writer is generated by applying a feature extraction algorithm of individual characteristics based on handwriting information. Using the generated personal key, a telewriting system which has a function of the encryption of handwriting information as well as a function of the authentication of a writer is realized. From some simulation results using handwriting data, it is clarified that the proposed telewriting system realizes the above two functions by using each writer's personal key.
