<p><strong>Abstract:</strong></p>

<p>In a domain dealing with risks associated with the often quoted fast-changing technological landscape, it is surprising that one of the main tools we rely on has been more or less stable for so long.

The poster presents the findings of a brief study taking a closer look at DROID signature pattern changes over the course of time.</p>
