A NEW METHOD FOR REDUCING THE EFFECTS OF INCREASING INFORMATION IN DIGITAL IMAGE STEGANOGRAPHY

Nowadays, in order to transfer data, security is one of the most important parameters in the evaluation for transmission techniques. According to th e development communicational devises, possibility of data theft submissions, which should be out of reach, increased. Using images in order to store some information on them is one of the safest ways to send specific information. Considering that each ima ge is composed of pixels, each pixel has a specific value . Added information on changes in specific areas of the image, in this case, that information may be stolen. In this paper, a new method of digital image steganography, for decreasing of changes of i mage and security enhancement, is presented. The propose method makes it possible to recover the data without loss of information. The results of implementation showed that after applying the proposed method, the possibility of detecting location and the v alue of information is very low.
