A Comprehensive Survey on ECG signals as New Biometric Modality for Human Authentication: Recent Advances and Future Challenges

Anthony Ngozichukwuka Uwaechia, Dzati Athiar Ramli
2021 IEEE Access  
Among the most generally employed biometric traits include fingerprints, palmprint, iris, voice, and face recognition, and identification requires the enrolment of these traits in a database for feature  ...  Down-sampling improves the phase angle resolutions and makes it more straightforward to classify the corresponding ECG waveform feature required for biometric identification.  ...

Representation Learning and Pattern Recognition in Cognitive Biometrics: A Survey

Min Wang, Xuefei Yin, Yanming Zhu, Jiankun Hu
2022 Sensors  
Recent research has demonstrated great potential for using cognitive biometrics in versatile applications, including biometric recognition and cognitive and emotional state recognition.  ...  A taxonomy is designed to structure the corresponding knowledge and guide the survey from signal acquisition and pre-processing to representation learning and pattern recognition.  ...  features relative to the peak, interval, amplitude, slope, angle, and power ratio are extracted [35] [36] [37] [38] [39] .  ...
