Application of a novel Anonymization Method for Electrocardiogram data
Zineb Bennis, Pierre‐Antoine Gourraud · 2021
Chronos, a time series oriented anonymization method is presented in this paper. The method is tested on electrocardiogram time series in the MIT-BIH Arrhythmia Data Base and the Physikalisch TechnischeBundesanstalt (PTB) Diagnostic ECG, with empirical measures of the privacy protection provided by the method. The signal retention properties of the method are also tested graphically and computationally by training algorithms on the original and anonymized sets. The models trained on the anonymized data achieve a 3% accuracy difference compared to the original models. The method outputs samples that are similar to the original data while protecting the records by producing new synthetic data points.
