First Claim
Patent Images
1. A computing device, comprising:
- at least one processor;
a storage system that stores an image file and a text file; and
the storage system that further stores one or more programs, which when executed by the at least one processor, cause the at least one processor to;
set a first rule for extracting text data from the image file and a second rule for verifying text data of the text file;
recognize the text data from the image file using an optical character recognition (OCR) according to the first rule;
process the recognized text data using a fault-tolerant lexicon to extract key text; and
verify the text data of the text file to match the text data of the image file, upon the condition that the text data of the text file comprises the key text according to the second rule.

Abstract
A computing device recognizes text data from an image file using an optical character recognition (OCR). The computing device processes the recognized text data using a fault-tolerant lexicon to extract key text. The computing device verifies that text data of a text file match the text data of the image file, upon the condition that the text data of the text file comprises the key text.
