Evolution, Current Challenges, and Future Possibilities in ECG Biometrics

Joao Ribeiro Pinto, Jaime S. Cardoso, Andre Lourenco
2018 IEEE Access  
In the last years, the topic of ECG-based biometrics has quickly evolved toward the commercial applications, mainly by addressing the reduced acceptability and comfort by proposing new off-the-person,  ...  Commercial products using these traits for biometric identification or authentication are increasingly widespread, from smartphones to border control.  ...  In general, metric-based methods offer less accuracy than methods based on classifiers, but they gain some robustness by not having to be trained on a specific dataset, and thus do not depend much on the  ...

Privacy-Protecting Techniques for Behavioral Data: A Survey [article]

Simon Hanisch, Patricia Arias-Cabarcos, Javier Parra-Arnau, Thorsten Strufe
2021 arXiv   pre-print
We taxonomize and compare existing solutions regarding privacy goals, conceptual operation, advantages, and limitations.  ...  Our behavior (the way we talk, walk, or think) is unique and can be used as a biometric trait. It also correlates with sensitive attributes like emotions.  ...  In a first phase, the authors propose computing the discrete cosine transform (DCT) of the ECG signal's autocorrelation coefficients, and then removing those DCT coefficients with the lowest energy.  ...

Introduction [chapter]

2016 Music Data Analysis  
This series aims to foster the integration between the computer sciences and statistical, numerical, and probabilistic methods by publishing a broad range of reference works, textbooks, and handbooks.  ...  The interface between the computer and statistical sciences is increasing, as each discipline seeks to harness the power and resources of the other.  ...  Therefore, autocorrelation functions of different intervals are analyzed and ranked by defining the so-called generalized coincidence function.  ...
