EFFECTIVE SYSTEM AND METHOD FOR VISUAL DOCUMENT COMPARISON USING LOCALIZED TWO-DIMENSIONAL VISUAL FINGERPRINTS
First Claim
1. A method for detecting and highlighting changes in documents and displaying the documents in a side-by-side aligned view, the method comprising:
- detecting aspects of a source document and a revised document, by an electronic processor device configured for the detecting;
comparing the detected aspects of the source document and the revised document, by the electronic processor device configured for the comparing;
identifying at least one of similarities and differences between the source document and the revised document, by the electronic processor device configured for the identifying;
introducing visual indicators to maintain consistent and accurate alignment between the source and revised content, by an electronic processor device configured for the introducing of the visual indicators; and
outputting a merged single output file containing the aligned side-by-side view of the source document and the revised document, with all differences between the source document and the revised document visually identified, by an electronic processor device configured for the outputting.

Abstract
A method and system detects and highlights changes in documents and displays those documents in a side-by-side aligned view. Aspects of a source document and a revised document are detected and compared. Similarities and/or differences between the source document and the revised document are identified and visual identifiers are introduced to maintain consistent and accurate alignment between content in the source document and content in the revised document. A merged single file is output containing the aligned side-by-side view of the source document and the revised document, with all differences between the source document and the revised document visually identified.

15. A method for displaying and highlighting changes between two documents, comprising:
-
comparing any two files without relying on availability of accurately recorded change edit history in a proprietary and/or unknown application-specific manner; and displaying a rendered side-by-side aligned view of the two documents that accurately and coherently shows all the changes highlighted, while simultaneously preserving the individual visual look and integrity of the page content of both documents. - View Dependent Claims (16, 17)

18. An automated system configured to detect, highlight changes in a source document and a revised document, and to display the source document and the revised document in a side-by-side aligned view, the system comprising:
-
a document input system arranged to input the source document and the revised document; a detector system arranged to detect aspects of the source document and the revised document input via the document input system; a comparison system arranged to receive and compare the detected aspects of the source document and the revised document; an identifier arranged to identify at least one of similarities and differences between the compared aspects of the source document and the revised document; visual identification elements configured to maintain consistent and accurate alignment between the source and revised content; and an output display device to output and display a merged single file containing an aligned side-by-side view of the content in the source document and the revised document, with all differences between the source document and the revised document highlighted in place without disturbing the overall visual layout of the page. - View Dependent Claims (19, 20)
