摘要：Smartphones are being used to keep sensitive data and make private transaction other than making calls and receive short messages. Thus, authentication of the smartphones becomes very crucial and important aspect. However, users feel inconvenience and difficult with current authentication methods, from password up to physical biometrics. Implicit authentication system emerged intending to improve the security and convenience of the smartphone users. One of the approaches is considering the way users answer incoming phone calls using their smartphones. We study and evaluate the voice signal from users when answering incoming phone calls. Our study shows that the voice signals capable of authenticating the smartphone users. The experiment conducted shows a very high performance with 98.9% accuracy. These findings will promisingly augment that the novel implicit and transparent authentication system based on voices of answering incoming phone calls is feasible so that authentication of smartphone�s users become easier and unobtrusive.
