Patent Application
20100033753
The subject application is directed generally to redaction of documents. The application is particularly applicable to redaction of information on scanned documents.
It is frequently desirable to convert tangible documents to electronic documents, such as bitmapped image data. This conversion is done via a scanner. Modern data copiers employ scanners, as well as functionality to immediately create a tangible output from a scanned document.
It is frequently desirable to mask one or more portions of a document from scanning or reproduction. By way of example, it may be desirable to reproduce a credit card statement as proof of payment. However, such reproduction may result in an image that exposes much more confidential information than is warranted for a particular situation.
In accordance with one embodiment of the subject application, there is provided a document processing system and method for selective redaction of scanned documents. A tangible document is scanned so as to generate electronic image data corresponding thereto, and an image of the tangible document is generated on an associated touch screen display in accordance with the generated electronic image data. Tactile input is received on a first area of the touch screen corresponding to a first perimeter portion of a selected redaction boundary area and on a second area of the touch screen corresponding to a second perimeter portion of the selected redaction boundary area. Image data is then obfuscated corresponding to the selected redaction boundary area. The touch screen display is updated such that image data is hidden in the selected redaction boundary area, and image data inclusive of obfuscated image data is stored in the selected redaction boundary area in an associated memory.
Still other advantages, aspects, and features of the subject application will become readily apparent to those skilled in the art from the following description, wherein there is shown and described a preferred embodiment of the subject application, simply by way of illustration of one of the modes best suited to carry out the subject application.

Tactile input is then received from an associated user at step 906 on a first area of the touch screen 106 or 116 corresponding to a first perimeter portion of a selected redaction to boundary area. At step 908, tactile input on a second area of the touch screen 106 or 116 corresponding to a second perimeter portion of the selected redaction boundary area is received by the controller 108 or other suitable component associated with the document processing device 104 from the associated user. The controller 108 then obfuscates image data corresponding to the selected redaction boundary area at step 910. At step 912, the touch screen display 106 or 116 is updated such that image data is hidden in the selected redaction boundary area. Thereafter, at step 914, image data inclusive of obfuscated image data in the selected redaction boundary area is stored in the data storage device 110. In accordance with one embodiment of the subject application, the image data is communicated via the computer network 102 to the user device 126 for storage thereon.

At step 1006, tactile input on a first area of the touch screen 106 or 116 corresponding to a first perimeter portion of a selected redaction boundary area is received from an associated user. Tactile input on a second area of the touch screen 106 or 116 corresponding to a second perimeter portion of the selected redaction boundary area is then received from the associated user at step 1008. At step 1010, the selected redaction boundary area is formed on the touch screen 106 or 116 as a generally rectangular area defined by the tactile input in the first and second areas of the touch screen 106 or 116. The rectangular area is then generated at step 1012 in accordance with a dragging tactile input between the first and second areas of the touch screen 106 or 116. A suitable example of such action is illustrated in
Image data is then obfuscated by the controller 108 or other suitable component associated with the document processing device 104 at step 1014, corresponding to the selected redaction boundary area. The touch screen display 106 or 116 is then updated at step 1016 such that image data is hidden in the selected redaction boundary area, e.g. the text, graphic, photograph, or the like is hidden. Image data, inclusive of the obfuscated image data in the boundary area, is then stored in the data storage device 110 at step 1018. A determination is then made by the controller 108 or other suitable component associated with the document processing device 104 at step 1020 as to whether to output the redacted document 124. Upon a determination at step 1020 that the redacted document 124 is to be output, flow proceeds to step 1038, whereupon the redacted document 124 is output by the document processing device 104 in accordance with the obfuscated image data. It will be appreciated by those skilled in the art that such output is capable of including, for example and without limitation, printing the redacted output document 124, communicating such redacted output document 124 to the user device 126, facsimile transmitting the document 124 to a designated recipient, or the like.
Returning to step 1020, when it is determined that a redacted document is not to be output, flow progresses to step 1022, whereupon selection data is received for at least a second redaction boundary area of the tangible document 122 displayed on the touch screen 106 or 116. At step 1024, tactile input on a third area of the touch screen 106 or 116 corresponding to a first perimeter portion of the second area is received from an associated user. Tactile input on a fourth area of the touch screen 106 or 116 corresponding to a second perimeter of the second area is then received from an associated user at step 1026. The controller 108 or other suitable component associated with the document processing device 104 then forms the second selected redaction area as a generally rectangular area defined by the tactile input in the third and fourth areas of the touch screen 106 or 116 at step 1028. The rectangular area is then generated in accordance with a dragging tactile input between the third and fourth areas of the touch screen 106 and 116 at step 1030.
The controller 108 or other suitable component associated with the document processing device 104 then obfuscates image data corresponding to the second selected redaction boundary area at step 1032. The touch screen display 106 or 116 is then updated at step 1034 such that the image data within the selected area is hidden. It will be appreciated by those skilled in the art that the selected area is capable of being obfuscated via overlaying a solid color block in the selected boundary area, such as a solid black rectangle, a solid white rectangle, or the like. In one such embodiment of the subject application, the rectangular block is color-coded to match the background of the tangible document 122, as will be appreciated by those skilled in the art. The controller 108 or other suitable component associated with the document processing device 104 then appends data in the data storage device 110 to include image data inclusive of the obfuscated image data in the second boundary area at step 1036. Flow then proceeds to step 1020, whereupon a determination is made as to whether to output the redacted document 124. Upon a negative determination, flow returns to step 1022, whereupon another redaction area of the image of the tangible document 122 displayed on the touch screen 106 or 116 is selected by the associated user. Operations then proceed thereon as set forth above with respect to step 1024 through step 1036. When it is determined at step 1020 that the redacted document 124 is to be output, flow proceeds to step 1038. At step 1038, the redacted document 124 is output by the document processing device 104 in accordance with the obfuscated image data corresponding to all redacted boundary areas.
