摘要：Photocopy documents are very common in our normal life. People are permitted to carry and presentphotocopied documents to avoid damages to the original documents. But this provision is misused fortemporary benefits by fabricating fake photocopied documents. Fabrication of fake photocopied documentis possible only in 2nd and higher order recursive order of photocopies. Whenever a photocopied documentis submitted, it may be required to check its originality. When the document is 1st order photocopy, chancesof fabrication may be ignored. On the other hand when the photocopy order is 2nd or above, probability offabrication may be suspected. Hence when a photocopy document is presented, the recursive order numberof photocopy is to be estimated to ascertain the originality. This requirement demands to investigatemethods to estimate order number of photocopy. In this work, a voting based approach is used to detect therecursive order number of the photocopy document using probability distributions exponential, extremevalues and lognormal distributions is proposed. A detailed experimentation is performed on a generateddata set and the method exhibits efficiency close to 89%.
