“…As the proposed method involves both the cryptographic and steganographic concepts (19,21,22) for strengthening the security, it is called Dual Level Security Scheme (DLSS). Cryptography is the process of converting the plain signal into cipher signal, on the other hand, Steganography is the process of hiding the secret signal in covering signal.…”

Objectives: Recent trend depicts a steep hike in the value of data. Data in all forms are vulnerable and especially multimedia data are fascinated by hackers Hence, strong security measure has to be applied before attempting to use the unsecure transmission medium for sharing secret / personal data. Methods: Dual Level Security Scheme (DLSS) is proposed which combines cryptography and steganography techniques to ensure double level security. Cipher image is obtained by applying Spiral Mapping and discrete cosine transformations (DCT) in RGB Layers. Then, the cipher image is hidden in the audio signal. Findings: SNR value is considered for normalizing the signals before embedding it, to obtain final signal without any traces of the hidden secret signal. Core objective of using DLSS is maintaining the secrecy when data transmission is taking place in any unsafe medium. Simulation results of our proposed method exhibit an average of 10% improvement and hence, DLSS outperforms well over the existing methods. Competence of the method is evident from the performed histogram analysis. Standard image dataset is used and directional correlation, PSNR, SSIM, and MSE are the considered measures to prove DLSS efficiency. Novelty: Here, a novel method Dual Level Security Scheme (DLSS) with spiral mapping is proposed to incorporate the aids of cryptography and steganography for enhanced efficiency.

“…Embedding the secret data in a multimedia data adds security. Hiding image in an audio file [6] is shown by Tohari Ahmad et al and embedding secret audio in another cover audio is proposed in our previous work [7]. As the multimedia data are huge and very vulnerable, the amount of data hidden in a cover file is an important measure to prove the efficiency of the system.…”

In the modern digital era, data is considered to be the most valuable asset. Multimedia data includes audio, image and video forms which grabs attention and vulnerable for hacking. Transmission of multimedia data in open network is always unsecure. In this research paper, a novel method to transmit secret video is proposed. First, keyframes are detected by processing the ROI (region of interest) to classify segments. Spiral Shuffling and SHA512 hashing technique are applied to build the cipher blocks. Blockchain technique enhances strength of the Dual Level (Crypto-Stegano) Security Scheme. Discrete cosine transformation with normalization is applied to embed cipher blocks in audio files without any traces of hidden data. Combining the major security techniques such as Cryptography, Steganography and Blockchain enhances the strength of the proposed BDLSS (Blockchain enabled Dual Level Security Scheme). Experimental analysis is carried out with PSNR, SSIM, MSE, NPCR and Correlation coefficient values to prove the efficiency and the proposed method outperforms well over existing methods.
