The word steganography has originated from two Greek words, namely, stegos and grahia meaning cover and writing, respectively. The concept behind steganography is that the transmitted message should be indiscernible to the regular eye. It is the art of concealing information within a medium. The main aim of steganography is to protect this concealed information. A message transmitted using a cipher text may incite suspicion, but an invisible message will not. Digital images constitute a flexible medium for carrying secret messages because slight modifications done to a cover image is hard to be distinguished by the human eyes. In this work, we have proposed an Image Steganographic Scheme using 8 × 8 Sudoku puzzle for secure data transmission. The originality of the work is that if any intruder changes any part of the secret message, then the proposed algorithm will be able to detect it. © Springer Nature Singapore Pte Ltd. 2017.

A Novel Image Steganographic Scheme Using \(8 \times 8\) Sudoku Puzzle

Advances in Intelligent Systems and Computing

Video steganography is the method of hiding the presence of data within the cover video. In this paper, a novel video steganography technique is revealed, where with the help of Sudoku puzzle of order 9 × 9, extracted image frames of a cover video are utilized to hide encrypted data. The novelties of the work imply that as the input information is first encrypted into cipher text using a new modified substitution and permutation network (SPN)-type block cipher, then, that cipher text is embedded in the video using Sudoku puzzle as a key. This new and robust encryption model is like a block cipher in comparison with Advanced Encryption Standard (AES) that provides enhanced resistance in case of fault attack. This new SPN-type architecture differs with AES architecture in the step of round key mixing function. Its computation complexity is much higher compared to original AES to find 128 bits of tenth round key. Therefore, our proposed work combines both cryptographic and steganographic technique and Sudoku puzzle to enhance the security in maximum level with optimal computational complexity and good embedding capacity rate. © 2019, Springer-Verlag London Ltd., part of Springer Nature.

A novel SPN-based video steganographic scheme using Sudoku puzzle for secured data hiding

Video Steganography is a method for securing data in a video file and hence it prevents the chance of theft. The proposed scheme uses the Video Steganography technique on the encrypted data (using RSA and AES) for providing maximum security and stability. In this work, a secured Video Steganographic scheme is proposed using Sudoku puzzle. The novelties of the work imply that nobody could be able to see as well as modify data during transmission as the secret message is first encrypted into cipher text twice using RSA and AES cryptographic technique then that cipher text is embedded in video using a Sudoku reference matrix. So, our proposed work combines both Cryptographic and Steganographic technique to enhance the security in maximum level with maintained computational complexity. © 2018, Springer Nature Singapore Pte Ltd.
