A Secure Video Steganography Based on ECC and DCT

Abstract

Video steganographic algorithm has the advantage of large hiding capacity, but we neglect the security when seek the capacity. In order to balance the two aspects, both to meet the high capacity of improving the load of video carrier and can safely protect the secret information. This paper presents the error-correcting code which can effectively correct burst errors and use it in video steganography. The secret information is hidden in error-correcting code first and then integrated the code with secret information with the video carrier’s DCT coefficients to insert the secret information in video carrier. The experiment results show that: this algorithm not only has great visual and statistical invisibility, also the safety of secret information is more significant. And achieve the objective of effective protect the secret information.
