Multimedia material, such as digital video, is utilized to conceal a secret message.Given the features of digital video, which has a large storage capacity, confidential data may be inserted.Three requirements must satisfy to grantee secure steganography system.These requirements include security, robustness, and imperceptibility.This paper proposes a steganography scheme to enhance the security of video steganography and attempt to meet the three requirements mentioned above.The security requirement is accomplished through two levels.In the first level, the secret message is encrypted before the embedding process using proposed encryption method based on a combination of chaotic and Arnold's map.In the second level, the secret message is embedded in the selected frames of the video.Instead of traditional LSB technique, we will use a modified LSB technique to meet the robustness requirement.A modified LSB technique is satisfied by embedding the secret message in the LSB of cover video in frequency domain after applying the integer wavelet transform (IWT).According to the experimental results, the stego video quality is like the original video where the obtained PSNR value was 61.922, so the third requirement, imperceptibility, was satisfied.
