GIF IT UP

1- JPHIDE

JPHIDE is program which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE is rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from “normal” to the extent that it raises suspicion. Above 15% the effects begin to become visible to the naked eye. Of course some images are much better than others when used a host file – plenty of fine detail is good. A cloudless blue sky over a snow covered ski paradise is bad. A waterfall in a forest is probably ideal.

1- GIF IT UP

Gif It up Steganography Software is a free program that allows you to hide information in Graphics Interchange Format (GIF) images. Gif It Up allows you to embed text, sound, image, spreadsheet, and zip files into a GIF image. GIF images are 8 bit per pixel images that support up to 256 colors. Most computers are sold with a program that will allow you to open, edit, copy and save images in a GIF format. Although the software will allow you to hide information from multiple formats, the base image has to be a GIF image. Simple graphics, logos and animations are typically saved as GIF images because of the limited range of colors. The physical size of images can cause a web page to load slowly. Reducing the size of your images reduces the size of the file that you can hide in the GIF image.
