Data Security Approach in IoT Environment

The growth of internet has introduced different types of services which includes actuators and sensors proving remarkable and outstanding performances. It is found that the greatest current issue in IoT field is to obtain an easy and a safe access control scheme for the large amount of data. So there is a need to discover some solutions of security. This study discusses about the open API service which is a web service called as the IoT Thingspeak platform. It plays as a host for a different numbers of sensors for sensing and monitoring patients heart rate and temperature data at cloud level and further the data is being ported to MATLAB R2017a with the help of a channel ID. In MATLAB R2017a security is being applied to the patients data using GUI login details. The proposed technique is used for retrieving data securely at the end user. This work makes use of hardware components such as Arduino UNO board, ESP8266 Wi-Fi Module, Pulse sensor, LM35 Temperature sensor for processing and transferring the sensed information to the Thingspeak cloud.
