Abstract: Data hiding techniques used in image Steganography focus on the transformation of the LSB bit of the image matrix of pixels. Their transformation comes as a result of the respective binary values of the text that is intended to be hidden, or that will serve as a hidden watermark for the image. In some cases the textual content of the message is very simple. For example, in Image Information Systems used in healthcare institutions, they preserve the patient data, or in seismology they contain date stamps, coordination and description. For this reason, using the ASCII binary codes of text is sometimes bitconsuming. In our paper we will analyze the nature of text of such messages that are intended to be hidden, and which are written in the Albanian language. We will test different contents of datasets and will gain the statistical distribution of the 36 letters of the Albanian alphabet, which will be used in the Huffman scheme of encoding. These results will be compared with the traditional compression of bits and we will show the percentage of gain in all the cases. The result will be applied in the distribution of bits in the image.
