Abstract: The rapid growth development of the Internet of Things (IoT) has supported communication between various smart devices and it helps to exchange data between them. IoT is very highly demand topics between the researchers. The main goal of IoT in health care is to provide real time monitoring of the patient. But these new challenges also introduced the privacy and security to the health care data. Security is a major concern of the data. A system requires with authentic protocol for maintaining privacy of health care data. After going through all methodologies of the protocol encryption will be carried out of data of the health care with “two fish” encryption technique. At server side, it will automatically get decrypted after applying key. Two fish encryption algorithm is a block cipher algorithm of 128 bit. The key length vary until 256 bit. Key is divided in two parts as the first half of the key will encrypt the plain text and second half of the key will modify the encryption algorithm.
