Transferring data in a safe way is one of the things that have been of interest since ancient times. Data hiding or steganography is a method used to protect the data during its transmission. Coding is a method to represent the data in another shape, so a high level of security is achieved by using coding and hiding data together. The proposed method is a hybrid between coding and hiding, but this paper focuses on proposed a data coding part only, such that the cover text (that used for information hiding) will be used to extract private information between the sender and the receiver for coding process, and the output of the proposed coding method can be used for information hiding process.
Apply the proposed coding method will provide a high level of security and complexity and produce ASCII of non-printed characters which can be employed for steganography purposes to obtain complete similarity between secret text and cover text.
