With cardiovascular disease as the number one killer of modern era, ECG is collected, stored and transmitted in greater frequency than ever before. However, lack of existing research in secured ECG distribution forces patient privacy under serious threat. Moreover, without adopting secured ECG transmission and storage, HIPAA recommendations for patient privacy are being compromised. This paper presents a new ECG obfuscation method, which uses cross correlation based template matching approach to detect all ECG features followed by corruption of those features with added noises. Without the knowledge of the templates used for feature matching and the noise, the obfuscated features can not be reconstructed. Therefore, three templates and three noises for P wave, QRS Complex and T wave comprise the key, which is only 0.4%-0.9% of the original ECG file size. Only authored doctors possessing this …
