Abstract
Many governments have some form of "direct democracy" legislation procedure whereby individual citizens canpropose various measures creating or altering laws. Generally, such a process is started with the gathering of alarge number of signatures. There is interest in whether or not there are fraudulent signatures present in such apetition, and if so what percentage of the signatures are indeed fraudulent. However, due to the large numberof signatures (tens of thousands), it is not feasible to have a document examiner verify the signatures directly.Instead, there is interest in creating a subset of signatures where there is a high probability of fraud that can beverified. We present a method by which a pairwise comparison of signatures can be performed and subsequentsorting can generate such subsets.
