Fingerprint Identification Using Filter bank Technique

Fingerprint recognition technology, a branch of biometrics, utilizes unique fingerprint characteristics to verify identity. Evolving from manual fingerprinting methods to digital scanning, this technology is now widely applied in security, finance, healthcare, and mobile devices. Modern fingerprint sensors can scan beneath the epidermal layer, enhancing accuracy and anti-spoofing capabilities. Notably, the Filterbank technique improves fingerprint feature extraction using spatial-frequency filters, optimizing noise resistance and enabling recognition even with lowquality images. With cloud computing integration, this technology continues to advance, offering superior security and exceptional convenience.
