BitTorrent's Bram Cohen Unveils New Steganography Tool DissidentX

Sparrowvsrevolution writes "For the last year Bram Cohen, who created the breakthrough file-sharing protocol BitTorrent a decade ago, has been working on a tool he calls DissidentX, a steganography tool that's available now but is still being improved with the help of a group of researchers at Stanford. Like any stego tool, DissidentX can camouflage users' secrets in an inconspicuous website, a corporate document, or any other, pre-existing file from a Rick Astley video to a digital copy of Crime and Punishment. But it uses a new form of steganography based on cryptographic hashes to make the presence of a hidden message far harder for an eavesdropper to detect than in traditional stego. And it also makes it possible to encode multiple encrypted messages to different keys in the same cover text."

      I almost modded that as Troll, but maybe it's insightful if decoded with a different key.

    It's probably better to work on this kind of thing in silence until it's released...

    Or even beyond that point.

    I released a similar tool two years ago and I'm still eagerly waiting for someone to discover it.

    All the other side needs to know is that you have something to hide, and depending on the level of society you live on, water boarding, lead pipes, or court order to make you divulge what it is.

    Unsophisticated societies use lead pipes to force people to divulge information.
    Sophisticated societies use court orders.
    Modern societies use waterboarding.
    Postmodern societies use facebook.

    Think about it.

    I sent you an email to say thanks but it would have looked like a letter from a Nigerian diplomat.

    it would surprise me if they don't have automated tools to spot steganography. (i.e. They know exactly what the formatting of say a Word document should be, and should have the capability to automatically flag traffic which has nonstandard information in the headers or data.)

    Have you seen the formatting of Word documents that come out of your typical user?
    You don't hit the "enter" key to make space, you jackasses. That creates a new fucking paragraph. Edit the paragraph's spacing if you want space below it. If you want an actual newline+carriage return, hit shift+enter. Stop using tab without first defining your tab stops to control where you want shit to be. Why are you using tabs to make columns anyway? Why are you trying to make columns (incorrectly via tabs) when what you want is a table? That's it, you're getting party vanned.
