5. A secure document data capture system for generating a data structure, comprising a data field value associated with each of a plurality of identified data fields, from a document image comprising text representing each of such data field values, the secure document data capture system comprising: a character recognition system receiving the document image and recognizing characters within the text to generate, for each of the identified data fields, a data field value for association therewith; a validation engine for identifying suspect characters, each suspect character being a character which fails to comply with a validation rule thereby indicating that that character recognition system erred in recognizing such character; an exception handling system: providing an exception image to a first client system, the exception image comprising a portion of the document image which includes text of a suspect character with a context portion of the document image redacted, the context portion of the document image being a portion of the document image which comprises text which discloses a meaning of the suspect character; and receiving from the first client system, user input of a replacement character for the suspect character; and the secure data capture system generating the data structure utilizing, for each identified data field, the data field values generated by the character recognition system with substitution of the replacement character from the exception handling system for each suspect character.
6. The secure document data capture system of claim 5 , wherein: the exception handling system further: provides the exception image to a second client system; receives from the second client system, user input of a replacement character for the suspect character; and the secure data capture system substitutes the replacement character from the exception handling system for each suspect character only when the replacement character form the first client system and the replacement character from the second client system are the same.
