It&#8217;s a model I believe can work, but I wonder how much is too much information to embed.  I think a watermark containing something like &#8220;This e-book prepared especially for John Doe (jdoe@jdoe.com)&#8221; is perfectly acceptable.</p>
<p>But, does that really put enough teeth into it?  I mean if you are not verifying email addresses, John Doe could easily put in something bogus and untrackable.  <strong>What if you put something really identifiable into the watermark &#8211; like the credit card number used to  purchase the book?</strong></p>
<p>If you are not sharing it then no harm no foul, right?  But does that cross a line in terms of trust?</p>
<p>What do you think?  How much information is too much for a social DRM watermark?</p>
