Abstract Maintaining secrecy of data in the digital media is much of the worked domain and requires more of it in the present. Steganography provides the secrecy provision by hiding the different types of into some of the cover objects available. This paper proposed two schemes of video steganography for hiding a secret audio into a cover video file by embedding audio bits into the extracted frames of the video through LSB embedding technique. Embedding techniques mentioned are namely sequential and random audio bits embedding. The security of the secret data is incorporated by the concept of chaotic sequence and XORing bit patterns before embedding the audio bits into the frames. The main aim of the two techniques proposed is to find out the suitable technique that fits into the required scaling of parameters for a good steganographic technique.

1 Introduction Audio steganography is another form of steganographic approach that ensures privacy and secrecy in the modern times. Hiding copyrighted information, government official secrets and convert channels secret communications could be facilitated by the audio–video steganography [1]. Any kind of noise persisting in the audio is susceptible to the HAS (Human Auditory System) and hence could be easily detected. So the task lies here is to come up with an unidentifiable scheme that could meet steganographic technique requirement for hiding acoustic data. This paper represents hiding scheme of an audio into a cover video at least significant N. Singh J. Bhardwaj (&) AKTU, Lucknow, India e-mail: [email protected] N.

bits position. The quality parameters that ensure the quality of the steganographic approaches are PSNR (Peak Signal Noise Ratio), Mean Square Error (MSE), NAE (Normalized Absolute Error), and Bit Error Rate (BRE). After embedding bits into the cover video, the values of PSNR should go high while MSE should go down, i.e., PSNR and MSE should hold inverse relation. The cryptography provides security to the digital information flowing in the network by converting it into different forms. The security approach used here is chaotic sequence. This chaotic sequence is used in cryptographic environment in order to provide randomness to the information. These sequences are in-decomposable, normalized elements, unpredictable, and create random values between the boundary ranges of [0, 1]. XORing among the random bits of secret data and the LSBs of the frames preserve the data and it could be reconstructed successfully after the extraction. Formula for the chaotic sequence is stated as follows: Xn þ 1 ¼ l Xn ð1 Xn Þ
