Reversible Data Embedding Scheme In Encrypted Image Using Arnold Transform for Satellite Images

An Satellite images are transmitted through the network undergoes security issues, losses in data and high confidentiality which concern the authenticity, integrity and security. In this paper, a secure data transmission in an encrypted image for the application of satellite images is discussed. Initially, the Arnold transform is utilized to obtain the encrypted image of the original image with a key. Then, to embed the message data, reversible data embedding scheme is applied. The text message is converted into a sequence of binary data and then embedded in an encrypted Image using the histogram shifting scheme. The reverse process is applied to retrieve the message and Image. The result shows that there is no distortion in the recovered image after extracting the secret message. Also it is observed the recovered message and identical to original message
