Abstract Cloud computing is used to share data, services and resources using internet connection. Data security is aimed to ensure security of data. Steganography is one of information hiding techniques used for solving this issue. It is the art and science of hiding data in a file in such a way that no one knows about the communication between sender and intended recipient. This work provides a novel method to image steganography using Discrete Cosine Transform DCT in frequency domain. Any two mid-frequency elements of the DCT coefficients are arbitrary chosen and used to hide secret message according to their values. |
