This paper presents a steganographic approach of concealing the secret data so as to facilitate secure communication. Arnold transformation has been imposed on the chosen cover image in the first stage. This results in the scrambling of the data bits, thereby disrupting the normal pixel orientation. Thereafter, Mid Position Value (MPV) technique is implemented to embed data bits from the secret image within the scrambled cover. Lastly, inverse Arnold transformation is applied on the above image. This results in a descrambling operation, i.e. reverting back the normal orientation. Henceforth the stego is generated. All the experimental results analyze the outcome of the full methodology. For this purpose, several quantitative and qualitative benchmark analysis pertaining to this approach have been made. All the results show that the imperceptibility, i.e. non-detectability of secret data is well maintained. Also the payload is high with negligible distortion in the image quality.
