Telehealth and remote monitoring improve healthcare accessibility but also expose sensitive data to security and privacy risks, where traditional authentication methods often prove inadequate. The electrocardiogram (ECG) has emerged as a promising biometric modality due to its inherent liveness detection, universality, and individual uniqueness. This paper reviews the ECG authentication pipeline, including signal acquisition through wearables, pre-processing techniques for noise reduction, feature extraction methods (fiducial, non-fiducial, and deep learning), and classification models. Publicly available datasets are examined, alongside key performance benchmarks. Persistent challenges-such as intra-subject variability, computational constraints in wearables, and ethical concerns are discussed, with future directions highlighting multimodal systems, privacy-preserving techniques, and standardized validation. ECG authentication demonstrates strong potential to become a secure and practical component of Telehealth systems.

This paper explores the integration of electrocardio-gram (ECG) biometrics into telehealth systems as a secure and user-friendly solu-tion. The rapid expansion of telehealth services has underscored the need for robust se-curity measures and personalized patient care. Traditional authentication methods, such as passwords and PINs, are prone to vulnerabilities and often fail to provide a seamless user experience. The study delves into the technical aspects of ECG signal acquisition, preprocessing, feature extraction, and classification, while addressing challenges such as noise, variability, and device interoperability.

The original protocol of key sharing of access to a secret is offered. This protocol differs in simplicity of implementation and integration of functions of decryption and test of data integrity in one arithmetical operation. The cryptographically strong of the offered protocol is based on computational complexity of the decision of the task of integer factorization.
