Abstract
As the applications of mobile and ubiquitous technologies have become more extensive, the communication security issues of those applications are emerging as the most important concern. Therefore, studies are active in relation with various techniques and system applications for individual security elements. In this paper, we proposed a new technique which uses the voice features in order to generate mobile one time passwords (OTPs) and generated safe and variable and safe passwords for one time use, using voice information of biometrics, which is used for powerful personal authentication optionally. Also, we performed the availability analysis on homomorphic variability of voice feature points using dendrogram and distribution of 15 users' voice skip sampling of feature points for the proposed password generation method. And we have described the application cases of the proposed mobile-OTP using skip sampling of voice signal.
