Abstract: With overwhelming use of internet, security is the top most priority while transferring data. This paper proposes a Joint encryption method along with Dual watermark embedding which gives ultimate security for multimedia file and also this procedure was implemented on color images. At first watermark is encoded with Chaotic mapping, after which it experience blended change inserting strategy dependent on DWT and DCT, with unique picture pursued by AES encryption for non-dazzle watermarking calculation. The DWT and DCT were joined to adapt to clamor issue and upgrade perceptual straightforwardness of watermarking picture. Our goal is to offer access to the results of the picture uprightness and of its inception despite the fact that the picture is put away encoded. This strategy gives better PSNR and relationship factors.
Keywords: AES, Toral Automorphism, Joint Encryption, Dual Watermarking.
