Cellular phones, which are now widely used, often contain significant amounts of personal information, and are also increasingly being used for money-related functions such as credit card purchases. Consequently, biometric authentication technologies are being introduced as a means to ensure higher security. However, these technologies can be vulnerable to criminal penetration. Because of this, the authors evaluated the security levels of cellular phones by a series of experiments using fingerprint authentication, face authentication, and voice authentication against criminal penetration. As a result, we found that the probability of successful authentication was 81% with an artificial fingertip, 87% with a face photo and 97% with a cellular phone display image, and 89% with a voice recording. As part of our research, we also evaluated the overall security of the above three biometric systems using the fault tree analysis method.
