I'm currently on the look out for new steganography ideas (you might have seen the patches I wrote that allow files to be hidden in gzip compressed files). I thought of a load of obvious stuff like adding/not adding spaces at the end of lines of a text file, carefully choosing assembler instructions where two are available, etc. Has anyone got any more ideas?
One possibility would be to right-justify your text, as a few people like to do, then to tweak the algorithm for inserting spaces into lines to depend on the next bits of the embedded mes- sage. Generally, you have N spaces to insert into M word breaks. If M divides N, you don't have any choice, but otherwise you have N mod M "leftovers" to distribute among M. This would allow several bits per line. Hal
