Abstract
A steganography method and an apparatus embedding a hidden message in a video stream of an original cover video to produce a stego video using a generative neural network. The original cover video is a video stream as opposed using an image. A discriminant neural network is used to correct a generated video compared to an original cover video. The generated neural network is trained when the generated video is determined to be real by the discriminant neural network. A second stego video is acquired by adversarial training through a mutually adversarial relationship between a generative neural network and an discriminant neural network. The embedding technique is one of pre-embedding, intra-embedding, or post-embedding.
