Here's talk of a non-DRM solution to dissuade people from sharing illegaly and suddenly the system needs to be 100% unbreakable. I'm not setting requirements here. What I meant is that stolen credentials and the resultant false accusations are an issue for the legitimate users who are falsely accused. You need to consider this and ask whether this risk for legitimate users is better or worse than the issues you see with DRM. > > > Also, if a watermarked copy is leaked because of a stolen password then at least it will be possible to inform that user and ask him/her to change their password.

I'm not talking about the average user stealing passwords. I'm talking about large scale infringement where an unsuspecting user is falsely accused because it is their watermark on the files being illegally distributed. That user suffers the stress and indignity of proving their innocence. I'm not making claims or judgements about the relative seriousness of this issue, only saying that it should be considered. ...Mark > > > > > -- > Emmanuel Revah > http://manurevah.com > >
