This study introduces a novel ECG-based security system using fused multi-domain features and adaptive Variational Mode Decomposition. It enhances data encryption robustness for the Internet of Medical Things.
Area of Science:
- Biometrics and Cybersecurity
- Signal Processing and Data Encryption
Background:
- Increasing security concerns with interconnected devices, especially in healthcare (Internet of Medical Devices).
- Limitations of traditional security methods (fingerprints, passwords) and existing ECG feature extraction techniques (time/frequency domains).
- The challenge of preserving intra-leading correlations in Variational Mode Decomposition for robust encryption.
Purpose of the Study:
- To develop a robust and lightweight encryption technique for sensitive data.
- To leverage unique human physiological signals (ECG) for secure key generation and data protection.
- To address the limitations of existing ECG feature extraction methods by incorporating multi-domain analysis.
Main Methods:
- Utilizing fused multi-domain Electrocardiogram (ECG) features.
- Applying adaptive Variational Mode Decomposition (VMD) to capture intra-leading correlations.
- Developing a lightweight encryption scheme using fused ECG features and a bio-inspired key generation technique.
- Evaluating performance with metrics like mean, standard deviation, skewness, kurtosis, and execution time (e.g., Chacha20 at 27µs).
Main Results:
- Successfully extracted ECG features with specific statistical properties (mean: 0.0004, std dev: 0.0391, skewness: 0.1562, kurtosis: 1.2205).
- Demonstrated the effectiveness of fused ECG features and adaptive VMD in mitigating the loss of intra-leading correlations.
- Proposed a lightweight encryption scheme with a bio-inspired key generation method.
Conclusions:
- The proposed method offers a robust and efficient approach to data encryption using ECG signals.
- Fusing multi-domain ECG features with adaptive VMD enhances the security and reliability of encryption algorithms.
- This bio-inspired encryption technique is suitable for securing data in the Internet of Medical Things and other sensitive applications.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
