Systems and methods for analysis of writing in documents

A method of assessing the validity of a document using a computer system, comprising:

• providing the document to the computer system, wherein the document comprises pre-printed information and one or more information fields comprising writing;
• comparing, by the computer system, at least a portion of the pre-printed information of the document to at least one pre-printed profile representation;
• comparing, by the computer system, at least a portion of the writing in at least one of the information fields of the document to one or more writing profile representations derived from writing in at least one information field of at least one other document, wherein the at least one of the writing profile representations has been stored in the computer system;
• and
• assessing non-validity of the document provided to the computer system, wherein evidence of non-validity of the payment instrument comprises failure of at least a portion of the pre-printed information of the payment instrument to approximately match at least one pre-printed profile representation and failure of at least a portion of the writing to approximately match at least one of the one or more writing profile representations.

A system, comprising:

• a CPU;
• a data memory coupled to the CPU;
• and
• a system memory coupled to the CPU, wherein the system memory is configured to store one or more computer programs executable by the CPU, and wherein the computer programs are executable to implement a method for assessing the validity of a document using a computer system, the method comprising:
• providing the document to the computer system, wherein the document comprises pre-printed information and one or more information fields comprising writing;
• comparing at least a portion of the pre-printed information of the document to at least one pre-printed profile representation;
• comparing at least a portion of the writing in at least one of the information fields of the document to one or more writing profile representations derived from writing in at least one information field of at least one other document, wherein the at least one of the writing profile representations has been stored in the computer system;
• and
• assessing non-validity of the document provided to the computer system, wherein evidence of non-validity of the payment instrument comprises failure of at least a portion of the pre-printed information of the payment instrument to approximately match at least one pre-printed profile representation and failure of at least a portion of the writing to approximately match at least one of the one or more writing profile representations.

A tangible, computer readable storage medium comprising program instructions stored thereon, wherein the program instructions are computer-executable to implement a method for assessing the validity of a document using a computer system, the method comprising:

• providing the document to the computer system, wherein the document comprises pre-printed information and one or more information fields comprising writing;
• comparing at least a portion of the pre-printed information of the document to at least one pre-printed profile representation;
• comparing at least a portion of the writing in at least one of the information fields of the document to one or more writing profile representations derived from writing in at least one information field of at least one other document, wherein the at least one of the writing profile representations has been stored in the computer system;
• and
• assessing non-validity of the document provided to the computer system, wherein evidence of non-validity of the payment instrument comprises failure of at least a portion of the pre-printed information of the payment instrument to approximately match at least one pre-printed profile representation and failure of at least a portion of the writing to approximately match at least one of the one or more writing profile representations.
