Abstract

One of the challenges recently occurred in the concept of hiding data is the robustness of hiding data in the way that is difficult to access or detect. Most of the steganography schemes are based commonly on embed data within images or video frames on their original form (uncompressed domain). This paper presents a new methodology for data hiding in MPEG-2 video standard. Data will be embedding during the compression stage of the AVI-MPEG2 encoding. The BPCS algorithm has been modified and used in all our experiments for embed data, and the DES (Data Encryption Standard) algorithm has been used to encrypt data before hiding. It only embeds encrypted data bits in the quantized AC coefficients (low-frequency AC coefficients) of Y components (Luminance) for the I-Frame. The obtained results demonstrate that the proposed method has the considerable advantage over previous steganography schemes with a good PSNR values for the embedded frame.
