In Telemedicine applications, Digital watermarking is a technique to improve the security and authenticity of ECG signals transmitted to the doctor's end through GSM network. Keeping this in mind, the authors of this paper propose a new watermarking technique which embeds patient's identification inside the ECG signals that will enhance the security and authenticity of ECG signals. In this paper ECG...
In this paper, the authors propose a new ECG compression algorithm which embeds patient's identification inside the ECG data. The compressed file contains only ASCII characters. The proposed scheme also allows the decompression technique where the original ECG waveform can be exactly reconstructed and retrieve patient's identification from the ECG signal. The whole module has been applied to various...
Software based new, efficient and reliable lossless ECG data compression, transmission and feature extraction scheme is proposed here. The compression and reconstruction algorithm is implemented on C-platform. The compression scheme is such that the compressed file contains only ASCII characters. These characters are transmitted using internet based Short Message Service (SMS) system and at the receiving...
Efficient and reliable electrocardiogram (ECG) compression system can increase the processing speed of real-time ECG transmission as well as reduce the amount of data storage in long-term ECG recording. In the present paper, a software based effective ECG data compression algorithm is proposed. The whole algorithm is written in C- platform. The algorithm is tested on various ECG data of all the 12...
In the present paper, a software based effective ECG data compression algorithm is proposed. The whole algorithm is written in C- platform. The algorithm is tested on various ECG data of all the 12 leads taken from PTB Diagnostic ECG Database (PTB-DB). In this compression methodology, individual standard deviation of each part of the signal is calculated at first. To achieve a strict loss less compression...
