This paper presents a Steganography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on 3-D set partitioning in hierarchical trees (SPIHT) algorithm for video compression and bit-plane complexity segmentation (BPCS) Steganography. In 3-D SPIHT coding, wavelet coefficients in 3-D discrete wavelet transformed video are quantized into a bit-plane structure and therefore BPCS Steganography can be applied in the wavelet domain. Embedding rates of around 28% of the compressed video size were achieved for twelve bit representation of wavelet coefficients with no noticeable degradation in video quality.
