<b>[Please note that the funding presentation is currently considered

<p>
As it was stated in the introductory item, "Personal security and privacy"
<a href="objectives.html#sec"><img src="more.png" alt="more..."></a>
(objectives section), security has several defense lines. Besides
those stated there, another interesting weakness worth examining is
local inspection of cache and history files.
<p> In fact, one of the common browser "subproducts" is an extensive
cache record, that takes the form of a directory structure with local files,
and another that keeps track of the visited URLs
(or at least the most recent ones).
<p> As personal computers are seldom used by a single person, peer
inspection of those files can tap a huge load of information about
browsing habits, visited places, images viewed etc.
<p> Worse yet, if those files are inspected by a "trojan program", the
whole contents can be sent outside and recorded in an external server that
accurately profiles personal interests.
<p> Dillo avoids these problems by keeping the whole cache in memory,
so that after finishing a session, there're no saved files, nor a
visited URLs history.

<br>
Dillo already has:
<ul>
<li>Extraordinary <u>speed</u>, both on rendering and networking.</li>
<li><u>Innovative</u> concurrency handling that allows for a user interface
that's always responsive and that lacks busy-clock locks!</li>
<li>Minimal HW requirements (both on CPU and memory), that let
it run on <u>several platforms</u> including some handhelds!</li>
<li>Graphical user interface.</li>
<li>Support for HTML, XHTML, plain text, and image formats
(GIF, JPEG and PNG).</li>
<li>Tiny startup time (around 2 seconds!)</li>
<li>Minimal <u>size</u>:
<ul>
<li> Source is around 300 Kilobytes </li>
<li> Binary is less than 250 Kilobytes </li>
</ul>
That is around 40 times less than a big browser.
</li>
</ul>
<p>
Note that efficiency not only means gains for minimalistic HW, it also
allows better exploitation of desktops and servers. For instance:
<ul>
<li>An administrator can gather web information from the same server
he's working on without affecting its performance.</li>
<li>There's no problem with running dillo on a working database server
(browsing its manual for tunning information for instance).</li>
<li>Playing mp3 music while surfing the net.</li>
<li>Working with the GIMP, but also having an open dillo with the manual.</li>
<li>etc.</li>
