Cloud Data Protection Based On Crypto-Steganography Approach

Cloud computing offers various benefits that make it a great choice for both the businesses and individuals due to its advantages. Cloud computing provide ability for quickly scale up and down resources according to demand and reduces the need for companies to maintain and invest in the physical infrastructure. They can pay for the and resources or the services they use on a pay-as-you-go base. Moreover Cloud computing allows users to access several applications or data from anyplace with internet connection, using a variety of devices and facilitates real-time collaboration and file sharing among teams, regardless of their physical location. Despite all the great advantages of cloud computing, security concerns related to information privacy and private data security are among the most prominent obstacles that restrict the use of cloud computing on a larger scale. The use of various encryption algorithms or steganography techniques can contribute effectively to raising the level of security in the cloud data. Steganography consider as a practice for hiding information and data inside other non-secret data, like audio, images and text to embed of any hidden messages. The proposed approach provide Crypto-Steganography approach for protect sensitive cloud data by encrypt these data before hiding them in a selected channel for a color image as an embedding medium to provide an additional layer for security, and thus, will give an excellent values for distortion metrics (wPSNR, UIQI and C4) as it explained in experimental results.
