System and method for embedding and extracting key information
First Claim
1. A method for embedding key information into a printed document comprising the steps of:
- creating a first section comprising a first ink having a first color under white light; and
creating a second section comprising a second different ink, wherein the second ink comprises a fluorescent ink and has a second color under white light which is substantially the same as the first color, wherein the fluorescent ink has a fluorescence when subjected to fluorescent-exciting radiation, and wherein the first section and the second section are visually indiscernible from each other on the printed document in white light;
the second section comprising key information, which is selected or highlighted by a user during creation of the document, and the first section comprises non-selected information.

Abstract
In accordance with an embodiment of the invention, a method for embedding key information into a printed document is disclosed. The method comprises creating a first section comprising a first ink having a first color under white light; and creating a second section comprising a second different ink. The second ink comprises a fluorescent ink and has a second color under white light which is substantially the same as the first color, and the fluorescent ink has a fluorescence when subjected to fluorescent-exciting radiation. The first section and the second section are visually indiscernible from each other on the printed document in white light. Also, the second section comprises key information, which is selected or highlighted by a user during creation of the document, and the first section comprises non-selected information.

9. A method for extracting key information comprising the steps of:
-
subjecting a printed document to a first image scanner, responsive to visible light for acquiring a first image of a first section for providing a first signal indicative of the first image; and
subjecting the printed document to a second image scanner, responsive to fluorescent emission for acquiring a second image of a second section for providing a second signal indicative of the second image;
wherein the printed document is scanned into an electronic archival system, and key information of the second section is detected, extracted and indexed so that the scanned document can be retrieved based on the key information. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for extracting key information comprising:
-
a first image scanner, responsive to visible light for acquiring a first image of a first section of a printed document, for providing a first signal indicative of the first image; and
a second image scanner, responsive to fluorescent emission for acquiring a second image of a second section of the printed word processing document, for providing a second signal indicative of the second image;
wherein the printed document is scanned into an electronic archival system, and key information of the second section is detected, extracted and indexed so that the scanned document can be retrieved based on the key information. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A printed word processing document comprising:
-
a first section comprising a first ink having a first color under white light; and
a second section comprising a second different ink, wherein the second ink comprises a fluorescent ink and has a second color under white light which is substantially the same as the first color, wherein the fluorescent ink has a fluorescence when subjected to fluorescent-exciting radiation, and wherein the first section and the second section are visually indiscernible from each other on the printed word processing document in white light, the second section comprising key information, which is selected or highlighted by a user during creation of the document by word processing, and the first section comprises non-selected information. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
