JPHIDE and JPSEEK are software programs that enable the user to conceal a file within a jpeg image.
JPHIDE and JPSEEK are two highly-specialized programs that allow users to conceal files within JPEG visual images. While there are many similar tools available online, these two programs stand out due to their exceptional design objectives. The primary goal of the developers was not simply to hide a file – instead, they aimed to achieve this task in a manner that makes it impossible to detect the presence of a hidden file within the host file.
In a typical visual image, a low insertion rate – less than 5% – with the absence of the original file makes it highly challenging to determine whether the host file contains any inserted data. If the insertion percentage increases, the statistical nature of the JPEG coefficients can differ from the norm, raising suspicion. When it exceeds 15%, the effects become visible to the naked eye. However, some images work better than others as host files. Detailed images with lots of finer details provide better cover than basic images, such as those consisting of clear blue skies or snow-covered mountains.
Although relatively straightforward to use, these programs require installing the sources of the JPEG library jpeg-6a, which can be retrieved from software archives or a RedHat CD. After compiling the sources according to the given guidelines and completing the included "make test," users may use the provided commands to hide or search for their designated files. Overall, JPHIDE and JPSEEK are exceptional tools for a specific purpose, and the design objectives make them stand out from other similar software.
