Video Steganography Using DNA and Chaotic Sequence

Abstract

Background: Several activities or task is which are performed with the help of digital technologies not only makes life easier but also very fast. The world without digital technologies realization seems to be very hard. These activities involve the exchange of some messages, which sometimes needs security. Security in terms of confidentiality, integrity, availability. Objective: To develop an algorithm which can withstand against the snooping attack and traffic analysis. Method: DNA concept is used to perform the encryption process. After the encryption process has been performed, the resultant cipher text obtained can be made hidden into some of the randomly selected frames of video acting as a cover medium. The chaotic sequence has been used to select the random framed of carrier video. Results: Performance of proposed approach was evaluated on the different parameters and found satisfactory. Results obtained through histogram analysis clearly reflect observations that visual detection is very hard to observe. If spectral analysis is performed on the output generated by the encryption procedure of the proposed algorithm, the result will be encrypted message. Conclusion: Encrypting the required plain text, choosing a random frame and then hiding encrypted text in LSB of the chosen frame is the key concept of the proposed algorithm. The strength of DNA and Chaotic sequence is exploited in the proposed algorithm. Based on the survey and results obtained claim the strength of the proposed algorithm.
