Dual biometric encrypted authentication using Rasperry Pi processor

Abstract

Security is one of the main concerns in many sectors especially in banking. Many protection mechanisms such as passwords and number locks, PIN numbers have been used to identify the correct person. The biometric protection mechanism using fingerprints are also implemented. To ensure more security double biometric factors are implemented in this paper. Voice is a powerful factor to identify a speaker who is holding the account in banks. In addition to voice, usual face biometric features also considered for security in bank lockers. Both are transformed into encrypted format and stored to avoid database hacking. In this, Raspberry Pi board is used for implementation. To manipulate voice, devices like USB microphone and sound cards are used. For processing face image Raspi Cam is used. When
