Enhancing image security and privacy in cloud system using steganography

Cloud systems are a popular type of Internet-based computing that provides shared digital resources to computers and other devices on demand. Such systems also allow users uploading and offloading data to the cloud by mobile applications. There are some potential security and privacy concerns using mobile devices since cloud systems are usually in a public domain. This paper presents an efficient image protection method to secure the existence of important private images in the cloud by using steganography technique. Experimental results show that the proposed method is able to not only enhance image security but also increase the cloud storage capacity.
