Abstract
Disclosed are systems and methods for automatically verifying text of a native digital document having an image layer and a text layer. The text is detected by optical character recognition (OCR) of the image layer, and is compared to text at a corresponding location in the text layer. Normalization processing is performed on both the detected image-layer text and the text-layer text. When the image-layer text and the text-layer text do not match, the text-layer text may be used or an icon indicating that the image-layer text and the text-layer text do not match is rendered and displayed.
