Steganography is one of the best techniques to hide secret data. Several steganography methods are available that use an image as a cover object, which is called image steganography. In image steganography, the major features are the cover object quality and hiding data capacity. Due to poor image quality, attackers could easily hack the secret data. Therefore, the hidden data quantity should be improved, while keeping stego-image quality high. The main aim of this study is combining several steganography techniques, for secure transmission of data without leakage and unauthorized access. In this paper, a technique, which combines various steganographybased techniques, is proposed for secure transmission of secret data. In the pre-processing step, resizing of cover image is performed with Pixel Repetition Method (PRM). Then DES (Data Encryption Standard) algorithm is used to encrypt secret data before embedding it into cover image. The encrypted data is then converted to hexadecimal representation. This is followed by embedding using Least Signification Bit (LSB) in order to hide secret data inside the cover image. Further, image de-noising using Convolutional Neural Network (CNN) is used to enhance the cover image with hidden encrypted data. Embedded Zerotrees of Wavelet Transform is used to compress the image in order to reduce its size. Experiments are conducted to evaluate the performance of proposed combined steganography technique and results indicate that the proposed technique outperforms all existing techniques. It achieves better PSNR, and encryption/decryption times, than existing methods for medical and other types of images.

“…The combination of steganography and cryptography technologies can be a prime solution to strengthen security and maintain the confidentiality of data [3], where the main purpose of cryptography and steganography methods is to protect data from unauthorized persons. The process of getting the secret message (extracting the message) can be done by applying the cryptography and then the steganography based on the methods used in the hiding phase, where the selected methods for data hiding-extraction and data encryption-decryption must be secure and efficient [4].…”

Steganography is also known as data hiding, is a method of ensuring the security and confidentiality of digital data by hiding sensitive data in digital media. In video steganography, compression is the most demanding research area in block based video encoders. With the improvement of video coding equipment, the High Efficiency Video Coding (HEVC) delivers better coding efficiency. However, a large proportion of video frames showed system complexity and required a larger Coding Unit (CU) during encoding. Also, as the larger number of video frames were encoded, the time consumption was increased. To overcome such an issue, this research introduced the chaos with enhanced mapping technique to reduce computational complexity and fast encoding. In this research study, the position of each pixel of the secret video frame is calculated by the ELSB technique, where the existing LSB techniques have not considered this secret video frame's position which leads to high video distortion. In proposed chaos encryption with mapping method, the input video frames are encrypted by using logistic and henon mapping that simultaneously maintains quality and efficiency of the model. The HEVC technique compresses the input video frames and the proposed ELSB performs two functions namely replacement of LSB and matching of LSB which effectively embeds the secret video frames into cover video frames. Finally, the secret video frames are retrieved by HEVC technique with chaos decryption which provides security to the model. The results proved that proposed compression technique achieved PSNR of 35.81dB with average execution time of 40 seconds, but the existing H.264 compression technique achieved PSNR of 32.72dB with average execution time of 45 seconds.
