摘要：In this paper, we present some new methods and develop techniq ues with algorithms for hiding text behind the gray scale image. Steganographic technique allows the sender to communicate information to the receiver without a third party even knowing that so me communication is occurring. First, we embed a 512-bytes of text message in a 512 by 512 gray level image in each o f the bit planes from first to eighth bit. We have also given some new techniques of embedding a text message in the entire gray level of the image itself, instead of bit levels, like hiding the text message in memory locatio ns of image pixel values where the gray level is most repeated in column wise, row wise, abundant and odd abundant memory locations, equal / near equal to the gray level column wise, and entire image and at random locations. A comparison study is also carried out.
