摘要

Apparatus and a method are disclosed for reading (31) and authenticating documents. These documents include passports, driver's licenses, identity documents and documents of value, and they are read to obtain and verify information recorded thereon, and to test for and detect security features thereon to determine if such documents are genuine, counterfeit or have been altered. A first image is taken of a document under evaluation and, from the image, the size (32) of the document is determined, and that defines the document as being part of a smaller class of documents having the same size. Reference documents for all documents types are segmented and a correlation (36) number is determined for each segment.
