The library uses heavily quantized frequency\ncomponents to provide storage that is stabilized by the JPEG\ncompression process.  As a result, embedded bit strings are preserved\nunder a number of different transformations, including transcoding to\nhigher quality, DC or low frequency shifts in pixel value, and limited\nimage rescaling.\n\nPlease see *\"TRIST: Circumventing Censorship with\nTranscoding-Resistant Image Steganography\"*\nfor a detailed explanation on what this tool does and how it does it.\nA copy can be found here: \n```\nhttps://github.com/SRI-CSL/jel/blob/master/doc/jpegsteg.pdf?raw=true\n```\n\nGeneral Compilation\n-------------------\n\n\nPrepare the raw git repository first and generate configure and Makefile:\n```\nautoreconf -fvi\n./configure --enable-silent-rules\n```\n\nTo compile manually:\n```\nmake\n```\n\nDebian\n------\n\nTo make a Debian package:\n```\ndpkg-buildpackage -b -us -uc\n```\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsri-csl%2Fjel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsri-csl%2Fjel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsri-csl%2Fjel/lists"}
