Highly Secure Secret or Code Transform by Combination of Steganography & Encryption Technique Using Socket Communication

چکیده
Image Steganography is the art of hiding the secret data into a cover image. The proposed method presents a steganographic method which is based on DWT-Arnold method, where DWT is used to convert the cover image into frequency domain and Arnold method is used for encoding the QR code of secret message. The quality of the image can be maintained by preserving the low frequency coefficients since most of the information lies in that area. QR code payload guides the alteration of the ARNOLD values of DWT block. This method can be used by smart phones, smart video-cameras, email or LAN connection for business and consumer applications. This method has high PSNR and SSIM and survived chi-square test with 100% message recovery. However satisfactory security will be maintained as the QR code is difficult to decode.

Steganography is one of the methods of secret communication that hides the existence of message so that a viewer cannot detect the transmission of message and hence cannot try to decrypt it. It is the process of embedding secret data in the cover image without significant changes to the cover image. A cryptography algorithm is used to convert the secret messages to an unreadable form before emb...
