Review on ECG signal transmission and Hiding mechanisms

Wearable ECG monitoring devices are becoming more prevalent as technology advances. A lot of private patient information is tracked and disseminated globally. Secret patient information must be safeguarded. Electrocardiogram signals can be used in a number of different ways to conceal the patient's confidential information. The two main goals of the entire procedure are a) to encrypt the patient data and b) to restore the original ECG signal. Health Insurance Portability and Accountability Act (HIPAA) regulations state that any dangers to the confidentiality and privacy of patient information must be avoided. This study examines various ECG steganography approaches for concealing patient-specific information.
