摘要：The acquisition, processing and secure transmission of a patient’s physiological and physical parametersto a remote location has been done by Patient Tele monitoring System (PTS). The PTS uses the wireless channel forcommunication of patient’s data which is not secure as wireless channel is open for information being hacked byunauthorized person easily , where there is no patient’s privacy thereby this project proposes the improvement ofprotection system for secret data communication through encrypted data concealment in ECG signals. The proposedencryption technique is the chaos cryptography technique which encrypts the confidential data in to unreadable formand it is concealed in to the high frequency coefficient of the Wavelet decomposed ECG signals by the data hider. Thereversible data hider technique and LSB replacement algorithm is used for concealing the secret message bits into thehigh frequency coefficients. In the data extraction module relevant key is used to extract the secret data and decryptionkeys are used to get back original information .Finally the performance of the proposed technique and existingtechnique is analyzed based on image, data recovery and time consumption.
