“…But invisible watermark images are not easy to removable from the covered image. Multiple images in steganography are one of the techniques of embedding two secret images into one cover image (Wan Adnan et al , 2003). This type of technique of embedding images or data is very useful in many applications for security purposes.…”

PurposeSteganography is a data hiding technique used in the data security. while transmission of data through channel, no guarantee that the data is transmitted safely or not. Variety of data security techniques exists such as patch work, low bit rate data hiding, lossy compression etc. This paper aims to increase the security and robustness.Design/methodology/approachThis paper describes, an approach for multiple images steganography that is oriented on the combination of lifting wavelet transform (LWT) and discrete cosine transform (DCT). Here, we have one cover image and two secret images. The cover image is applied with one of the different noises like Gaussian, Salt & Pepper, Poisson, and speckle noises and converted into different color spaces of YCbCr, HSV, and Lab.FindingsDue to the vast development of Internet access and multimedia technology, it becomes very simple to hack and trace secret information. Using this steganography process in reversible data hiding (RDH) helps to prevent secret information.Originality/valueWe can divide the color space converted image into four sub-bands of images by using lifting wavelet transform. By selecting lower bands, the discrete cosine transform is computed for hiding two secret images into the cover image and again one of the transformed secret images is converted by using Arnold transform to get the encrypted/embedded/encoded image. To extract the Stego image, we can apply the revertible operation. For comparing the results, we can calculate PSNR, SSIM, and MSE values by applying the same process for all color spaces of YCbCr, HSV, and Lab. The experimental results give better performance when compared to all other spaces.

“…Conventional cryptographic systems allow only valid key holders to access the encrypted data and therefore provide limited protection against data piracy in environments where publisher is confronted with unauthorized reproduction of information. A digital watermark on the other hand complements cryptographic process [10], [11], [12], [13]. It is permanently embedded in the data and even after any decryption process it remains there.…”

Abstract─ The proliferation of digitized media has created a pressing need for robust watermarking schemes for protection of copyright ownership. The desired watermark characteristics include fidelity preservation, robustness to common signal and geometric processing operations, robustness to attack and applicability to audio, image and video data. This paper presents a framework for analyzing and evaluating the strengths of various watermarking algorithms. The focus is exclusively on the analysis of watermarking of digital images. The framework presented herein can however be extended to digital video and audio watermarking applications.
