Photocopy documents are very common in our normal life. In India, people are permitted to carry and produce photocopied documents frequently, to avoid damages or losing the original documents. But this provision is misused for temporary benefits by fabricating fake photocopied documents. When a photocopied document is produced, it may be required to check for its originality. An attempt is made in this direction to detect such fabricated photocopied documents. This paper proposes an unsupervised system to detect fabrication in photocopied document. The work in this paper mainly focuses on detection of fabrication in photocopied documents in which some contents are manipulated by new contents above it using different ways. Testing is performed with a different set of collected testing samples resulted in an average detection rate of 70.14%.
