Evaluation of Handwriting Characteristic for Two-factor Authentication Interface on Touch-pad Panel

Frequencies of user authentication increase and spread of smartphone and tablet advances rapidly in recent years. However, it is a great challenge that password authentication is easy to be attacked and must be solved. We assume authentication, which use touch panel and handwriting as an authentication element in this paper. As far as we know, there have few papers about generating a digital data from handwriting. Therefore, our contribution of this paper is to define handwriting characteristics of a letter that can convert into a digital data and evaluate possibility of the conversion.
