Raspberry Pi and IOT Based-Automated Teller Machine Security for the DSWD 4P's Biometric System Using Fingerprint Recognition with Fast- Fourier Transform Image Enhancement, Multi-Stage Minutia Extraction

Abstract

Card skimming and identity theft in ATMs transactions are prevalent nowadays. The use of the common PIN system together with the use of fingerprint as one's identification, eliminating the card skimming- and theft-prone typical card when the PIN is known, strengthens the current ATM transaction process. Images from fingerprint sensors undergo a multi-step process to provide proper user identification when transacting in ATMs. The researcher came up with the idea of designing a system to eliminate possibilities of card skimming and identity theft with the use of a fingerprint identification which is unique for each person. The system uses Fast Fourier Transform as one of its image process to produce better image quality to be used for minutiae identifications. The system's simulated performance indices showed an FAR and FRR of 0% and 15.79%, respectively, and accuracy of 92.11%. The image is remotely transmitted to a distant server wirelessly, implementing a full Internet of Things providing the system a better mobility for mobile ATM Setups in far places.
