abstract = {Document security does not only play an important role in specific domains e.g. passports, checks and degrees but also
in every day documents e.g. bills and vouchers. Using special high-security features for this class of documents is not
feasible due to the cost and the complexity of these methods. We present an approach for detecting falsified docu- ments
using a document signature obtained from its intrinsic features: bounding boxes of connected components are used as a
signature. Using the model signature learned from a set of original bills, our approach can identify documents whose
signature significantly differs from the model signature. Our approach uses globally optimal document alignment to build
a model signature that can be used to compute the probability of a new document being an original one. Preliminary
evaluation shows that the method is able to reliably detect faked documents.},
