{"Image DocumentName": "Abstract Background Challenges Contributions", "Image ImageDescription": "Traditional password/token based authentication schemes are insecure and are being replaced by biometric authentication mechanisms. Fingerprints were one of the first biometrics to be widely used. Despite 40 years of research, fingerprint recognition is still an open problem. Challenges. Feature extraction is very unreliable in poor quality prints. Matching fingerprints under non linear distortion is difficult. Contributions. New fingerprint image enhancement using STFT analysis. New feature extraction algorithm based on chain code contours. New graph based matching algorithm robust to non linear distortion.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
