And, some device manufacturers now allow application developers to use these features via their software development kits (SDKs). In this study, we utilize fingerprint scanning and recognition technology, a popular biometric security feature, to develop a web login authentication mobile app. Our application uses the Samsung Galaxy S5 fingerprint recognition feature and International Mobile Equipment Identity (IMEI) number to generate single time passwords. Within a limited time frame, the secure passwords can be used to sign in/log in to online user accounts related to government, banking, education, etc. As the production of mobile devices with fingerprint recognition continues to increase, finger print user authentication apps, like the one we introduce in this study, will become a prevalent security measure. Keywords: mobile devices; biometric security; fingerprint recognition; user login I. INTRODUCTION ODAY, mobile devices have become an important part of human life. Users access their e-mails, social networks, bank accounts, and various other websites via mobile devices. Mobile hardware manufacturers, operating system and application developers take a variety of security measures due to the personal, private and/or sensitive nature of the information stored in mobile devices. These measures include, but are not limited to passwords, PINs, patterns and biometric features. The use of biometric recognition on mobile devices started with cameras and microphones. More recently, mobile device manufacturers have added biometric authentication systems like the increasingly popular fingerprint recognition feature. This is a more secure and practical solution for identification on mobile devices. T
