From: "Herschel Mair" Re: DPI-was Image cathedral at Les Baux : If someone wants to steal your photo they can strip the EXIF etc, themselves. That's a real false sense of security. Very true. There's always a way for people to take what does not belong to them :( - and given the acceptance than a certain % adjustment to an artwork *can* (in some places) constitute a new artwork, we really have little / no protection from those who take what isn't there's. however. Steganography programs, most which are freeware, can quickly embed data like copyright info straight into *any* file such that it cannot be stripped without the appropriate steganography program. how does this help? You embed your chosen bit of info. Thief comes and pinches it, runs jstrip over it to remove all metadata and pops it on his web page. You have your attorney contact their attorney who's secretaries arrange an amicable coffee date (which they charge to you & thief) to decide whose turn it is to win the case based on the fact you can't prove anything and thief claims (rightly so) that anyone can embed exif data if they choose.. But You pop the image into the appropriate steg program (they're all different and the thief would need to try every one on every image to workout what image has had which information stuck into it) revealing to all the little marker (copyright, date, etc) and their case crumbles. They settle, you collect cash and buy new camera :) karl One such steganography program - though a google search reveals many free small programs for most OS's: http://www.sharewareconnection.com/titles/steganography.htm Imagehide Hide your sensitive data in image files.
