Hiding Secrets in Electrocardiogram Based on Integer Wavelet Transform with Coefficient Adjustment and LSB Substitution
Network and Communication Technologies
In this paper, we present an efficient data hiding for electrocardiogram (ECG) hosts to solve the issues of existing ECG steganographic methods, which have less hiding capacity and insufficient signal-to-noise ratio (SNR)/ peak SNR (PSNR). Based on the integer wavelet transform (IWT), private (or sensitive) data such as patients’ diagnosis and personal information can be embedded in an ECG host via the IWT coefficient adjustment and the least significant bit (LSB) technique.
