发明名称 DOCUMENT VERIFICATION SYSTEM
摘要 The present invention provides a document verification system capable of verifying whether a document is an original at low cost and with ease. A terminal device acquires, as a registered feature vector feature information indicating a feature of a nonreproducible disorder portion in a printing region on a document serving as the original, and stores the registered feature vector on a hard disk via the Internet. A server acquires, as a calculated feature vector the same information as the registered feature vector in a document to be verified as to whether the document is the original, reads out the registered feature vector from the hard disk, compares the acquired calculated feature vector with the read out registered feature vector, and verifies whether the document to be verified is the original on the basis of a result of the comparison.
