Image steganography is an emerging security technique to secure Intermet of Things based data.The sensitive data transferred or stored in the cloud storage has to be protected from the fraudulence.Any sensitive data from base station or an IoT device can be securely stored in cloud so that only intended user could access by using image steganography techniques which gives authentication.In this image steganography approach, the cover image is divided in to 3X3 matrices.The center pixels of the blocks are extracted to retain the feature of original cover image.This extracted center pixels are performed Exclusive-OR operation with the payload image.After XOR operation the image is shuffled by bit position and then embedded in to the original cover image.The proposed method is tested for several input images to show the robustness and shuffling is based on bits interchange instead of interchanging rows and columns hence the algorithm is more secure.The proposed approach uses the extracted center pixels as key for embedding instead of Local Binary Pattern encoding which reduces the complexity in computation and hence save the power required for any IoT applications.
