Nowadays, the science of information hiding has gained tremendous significance due to advances in information and communication technology. The performance of any steganography method relies on the imperceptibility, embedding capacity, and robustness against attacks. This research provides solutions for the existing video steganography problems by proposing new and effective methods for digital video steganography. The key objectives of our paper are as follows: 1) a highly secure video steganography algorithm based on error correcting codes (ECC); 2) an increased payload video steganography algorithm in the discrete wavelet domain based on ECC; 3) a novel video steganography algorithm based on Kanade-Lucas-Tomasi (KLT) tracking and ECC; 4) a robust video steganography algorithm in the wavelet domain based on KLT tracking and ECC; and 5) a video steganography algorithm based on multiple object tracking and ECC. The experimental results from our research demonstrate that our proposed algorithms achieve higher embedding capacity as well as better imperceptibility of stego videos. Furthermore, the preprocessing stages increase the security and robustness of the proposed algorithms against attacks when compared to state-of-the-art steganographic methods.
