摘要

Due to the rapid and immense development within information transmission and communications, there is a growing need for the usage of steganography techniques which greatly stimulated the emergence of intensive research activities to study steganography. The current paper submits a new system for steganography technique which relies on discrete transforms with SPIHT (Set Partition in Hierarchical Trees) algorithm. The system is able to hide secret massages in a colored cover image. This picture is split up into pixel blocks in the ratio 8x8. Haar wavelet transforms, DCT (Discrete Cosine Transform) and SPIHT algorithm are in turn used on each lock in order to get our (LIP) list, which points out the unnecessary pixels, which represent the optimum locations for hiding the secrete massage. The paper presented two ways for hiding, the first is in (band Blue) and the second is in (band Blue and Green), and we made a comparison between the results of the two methods. Another approach, which is based off of DWT (Discrete Wavelet Transform) as well as Haar wavelet transforms with SPIHT algorithm, is also presented in this paper. The two approaches were compared through capacity, correlation, PSNR and MSE.
