Data Hiding, ECG Watermarking, ECG Steganography, IWT


The authors present a data hiding method for electrocardiogram (ECG) signal based on integer wavelet transform (IWT). By using a simple coefficient adjusting technique, data bits can be rapidly embedded in an ECG host signal, and be successfully extracted at the receiver site. Simulations confirmed that the perceived quality introduced by the proposed method is good, while hiding storage is greater than existing techniques. In addition, the method has a certain degree of robustness. Since the proposed method provides the advantage of low time complexity, it is feasible for use in real-time applications.
