Masking of text in document reproduction
An apparatus for masking text in a rendered copy of an original document includes a text modification system which is configured to receive a print job from an application and modify the print job in accordance with a print job description, whereby when rendered on an output device, a selected text element is masked. A user interface is configured to receive instructions from a user to build the print job description including instructions for selecting text elements to be masked.
1. A method for masking text in an output document, comprising: providing a print job comprising an original document formed by scanning a hardcopy document comprising user applied highlighting; providing a print job description for the print job, the print job description including instructions for selecting text elements to be masked, the instructions including instructions for identifying user applied highlighting of text elements in the print job; modifying the print job in accordance with the print job description; removing the user applied highlighting from the print job; rendering the modified print job, from which the user applied highlighting has been removed, on an output device, whereby a selected text element is masked, the original document being unaffected by the masking process; and wherein the print job is provided in a native format and the modifying of the print job includes forming a modified print operation in a meta-format in response to the print job description, the method further comprising submitting the modified print operation in the native format to the output device.
2. The method of claim 1 , further comprising:
generating the print job description based on at least one user-selected category of text to be masked.
3. The method of claim 1 , further comprising:
processing the print job using optical character recognition; and
identifying the text element to be masked in the OCR-processed print job.
4. The method of claim 1 , further comprising semantically processing the print job to identify text elements in accordance with the instructions.
5. The method of claim 1 , wherein the output device comprises a printer.
6. The method of claim 1 , further comprising generating the print job by scanning the hardcopy document.
7. The method of claim 1 , wherein the applying a mask to a text element includes overlaying the text element with an opaque strip.
8. The method of claim 7 , wherein the instructions include a rule which selects a color for the opaque strip.
9. The method of claim 1 , wherein the applying a mask to a text element includes removing the text element from the print job.
10. The method of claim 7 , wherein the applying a mask to a text element includes replacing the text element with strip of substantially the same size as the text element whereby the layout of the print job is retained.
