摘要
Abstract
Android devices usually use digital or graphical password for unlocking screen,but such form of password is not safe enough,and some versions of Android exist keyguard bypass vulnerability.Therefore,this paper designs an Android keyguard system which uses user's unique voiceprint feature to unlock screen.This paper uses Mel Frequency Cepstrum Coefficient (MFCC) as the voiceprint feature and Dynamic Time Warping (DTW) for voiceprint pattern matching,and uses Android NDK technology to achieve quick voiceprint recognition.Experimental results show that this voiceprint keyguard system has a good unlocking success rate and unlocking speed,and compared with digital or graphical unlocking,unlocking screen with voiceprint is safer and gives users a better experience.关键词
