Secure Image Data Storage using Hybrid Cloud

Abstract: In IoT, increasing usage of image sensors and devices has led to a concern for storing the captured images and securing it, especially for big images. We make use of hybrid cloud structure for providing the framework for efficiently storing the images. The concept is to partition the image into most significant and less significant (remaining) image parts. The most significant part which is very less in size is stored in private cloud. The less significant part which constitutes major storage space is stored in public cloud. The two partitions are merged to form a full actual image when the user wants to retrieve the actual image. Sobel edge operator is used to partition the image. Encryption and compression schemes are employed to ensure privacy and reduce transmission bandwidth respectively.
