Enhance the Data Security in Cloud Computing by Text Steganography

Abstract

Cloud computing is new age computing model. Which gives that how to use the resources even if don’t own them. It gives the facility to share the resources over the internet, without building the necessary infrastructure. This is an on demand service. This model gives faster accessing of the resources and reduces management related problems. In this paper we are going to discuss the different cloud computing models with its advantages, characteristic and various security measures in the current scenario. At last we discussed a new level of security in cloud computing for data diffusion and storage on hybrid cloud in security concern. We are presenting new linguistic text steganography approach for increasing data security. In these techniques first we encrypt our secret data by using substitution method and then embed it in some random cover media for hiding the aspect of original text. We have proposed new method of Indian script encoding method and capital alphabet shape encoding which would be hard to decipher by inarticulate person. We are applying this techniques on private cloud server when we transfer our private data to public cloud so our data will also be secure in transmission and storage on public cloud.Time overhead of this techniques is very less and also it’s not taking too much space as one character of random cover is use to hide one character of encrypted secret text.
