Using Scenario Planning In The Evaluation Of Information Security Applications, Laura Perusco
Using Scenario Planning In The Evaluation Of Information Security Applications, Laura Perusco
Faculty of Informatics - Papers (Archive)
This paper provides a broad overview of the scenario approach as it relates to the evaluation of location based services (LBS) technologies and their appl ication. A scenario is a plausible vision of the future, based around a particular technology or application and developed via a scenario planning methodology. The main worth of the scenario planning approach is that it allows an application to be evaluated in terms of potential social impacts as well as technical merit and commercial viability. A sample scenario is presented within the paper to illustrate how the scenario planning methodology can be used. This scenario …

In previous work we have demonstrated that selective masking, or modulation, of digital images can be used to create documents and transparent media containing covert or optically variable, overt images. In the present work we describe new applications and techniques of such "modulated digital images" (MDI's) in document security. In particular, we demonstrate that multiple hidden images can be imperceptibly concealed within visible, host images by incorporating them as a new, half-tone, printing screen. Half-toned hidden images of this type may contain a variety of novel features that hinder unauthorized copying, including concealed multiple images, and microprinted-, color-, and various …
