| Abstract | ||
| Stegonagraphy is the art of hiding information through digital content in the internet Messages can be hidden inside all sorts of cover information: text, images, audio, video and more, making web pages a primordial means of action. Most currently steganographic techniques hide information inside images, as this relatively easy to implement but all resources are exploitable. These base images texts or audio are called covers and the result of joint of the cover and the message to hide is called stego. The most important property of a cover source is the amount of data that can be stored inside it, without being perceptible. When a cover is distorted, the cover source will be suspicious and may check more meticulously. A cover with a secret message inside can easily by spread over the world wide web or in newsgroups. Extensive use of internet increased the interest in developing algorithms and techniques of hiding information. Theses can be categorized in three groups (i) spatial domain techniques like LSB embedding, LSB matching, pixel value differencing, and stochastic modulation (ii) transform domain techniques like utguess, F5 , pathchwork, and BST- based Robust Image hiding method; (iii) other techniques which are not in spatial or transform domains techniques such as spread spectrum, statistical and distortion. We propose a new method to embed the text in Image , the method depend on the ASCII code value of character and compare it with the value of the palette of picture , if the ASCII Code value and value of palette is equal, we hide the place of value palette in another place in the picture , in this method we hide place not character. Then load the cover picture in web site on Internet in special website or through e-mail among group of pictures and we can change method of load between time and another. The main goal of steganography was fulfilled since the security text convey save by Internet. | ||
