Abstract
Methods and systems are provided for analyzing and assessing documents using a writing profile for documents, such as a payment instrument. A method may include providing a document to a computer system. In some embodiments, the method may further include obtaining information on writing in an information field of the document. In certain embodiments, the obtained written information in the information field and written information in at least one other information field may be compared to at least one writing profile representation. The writing profile representation may be obtained from at least one other document. In one embodiment, at least one of the writing profile representations may include written information from the information field and written information from at least one of the other information fields obtained from at least one of the other documents. In some embodiments, the comparisons may be used to verify the obtained written information.
