Spare Time

Spare Time Activity Sheets from Photo Albums

Given arbitrary pictures, we explore the possibility of using new techniques from computer vision and artificial intelligence to create customized visual games on-the-fly. This includes coloring books, link-the-dot and spot-the-difference popular games. The feasibility of these systems is discussed and we describe prototype implementation that work well in practice in an automatic or semi-autom...

How to Attack Biometric Systems in Your Spare Time

Biometric systems were proposed and developed to provide a better and stronger factor of authentication. Such systems authenticate individuals based on physical and behavioral traits such as fingerprints, iris, face, palm print, hand geometry, voice, etc. The use of biometric traits to replace existing passwords or as access keys has proven to be highly secure against physical attacks. It is a ...

On exploiting spare capacity in hard real-time systems

Spare Capacity Distribution Using Exact Response-Time Analysis

Real-time systems designed for use in dynamic open environments allow applications to enter and leave the system during runtime. This leads to changing runtime scenarios where the load and the spare capacity of hardware resources is influenced by the resource demand of running applications. Flexible real-time application components, with variable temporal parameters, can adapt their timing beha...

How to Own the Internet in Your Spare Time

Code Red I  first seen in mid 2001, spread using Microsoft’s IIS Webservers. This would infect one server and try to connect to other servers through port 80, jumping from one to the other. Buggy random number generator. Code Red II  same as CRI, except the bug was fixed and on top of it, it would attack http://www.whitehouse.gov. So it essentially DDOS’d (Distributed Denial of Service) on th...
