Abstract--We can simply define the wireless networks as ‘the system networks which are not interlinked by any cables’. Wireless network is a dynamic one both in the growth of productivity and be supportive in data transferring. The health status of a patient is submitted to a remote medical server via a portable digital assistance or cell phone may be tracked remotely by doctors. WBAN will help users to store their gathered information on their PDA (Personal Digital Assistant) or any other mobile computers and then pass that information to an appropriate server/computer. Medical data protection is a major subject in contemporary world. We proposed a new algorithm for encrypting and decrypting the ECG data using Holomorpic Algorithm through cloud services. ECC algorithm is used to generate the key for encryption process.
