    copied!<p>Where can I find a well-written, in-depth technical discussion about "private URLs" like the ones used in Google Docs' "anyone with the link" <a href="http://support.google.com/drive/bin/answer.py?hl=en&amp;answer=2494886&amp;p=visibility_options" rel="nofollow noreferrer">sharing setting</a>? I'm looking for topics like the algorithm and implementation for generating a link, the size of the ID space it uses, analysis of the security implications, and pragmatic compromises in security for convenience. I want to avoid reading dogma about "security through obscurity".</p> <p>I found one <a href="https://stackoverflow.com/questions/4833314/are-secret-urls-truly-secure">loosely related Stack Overflow question</a>, but it doesn't treat the topic in much depth, and the answers are more dogmatic and less pragmatic than I'd like.</p> <p>I searched Google Scholar for <a href="http://scholar.google.com/scholar?hl=en&amp;q=%22anyone+with+the+link%22&amp;btnG=&amp;as_sdt=1%2C22&amp;as_sdtp=" rel="nofollow noreferrer">"anyone with the link"</a>, <a href="http://scholar.google.com/scholar?as_ylo=2008&amp;q=%22secret+url%22&amp;hl=en&amp;as_sdt=0,22" rel="nofollow noreferrer">"secret URL"</a>, and <a href="http://scholar.google.com/scholar?start=10&amp;q=private+url&amp;hl=en&amp;as_sdt=0,22" rel="nofollow noreferrer">"private URL"</a>. I found a few interesting papers and patents, but I'm still interested to learn more about what the state of the art is.[<a href="http://scholar.googleusercontent.com/scholar?q=cache:OhoYbR3facwJ:scholar.google.com/&amp;hl=en&amp;as_sdt=0,22&amp;as_ylo=2008" rel="nofollow noreferrer">1</a>] [<a href="https://lirias.kuleuven.be/bitstream/123456789/272355/1/CW585.pdf" rel="nofollow noreferrer">2</a>] [<a href="http://www.google.com/patents/US6360254" rel="nofollow noreferrer">3</a>] [<a href="http://www.google.com/patents/US6718328" rel="nofollow noreferrer">4</a>] [<a href="http://www.google.com/patents/US6529956" rel="nofollow noreferrer">5</a>]</p>
