Abstract:
Systems and methods are described that facilitate encrypting document status information into a scanned image of a document using a mixed raster content document parsing protocol, in accordance with various features described herein. A text string comprising status information can be imaged into a mask layer that overlays the scanned image. Additionally or alternatively, the text string can be encrypted into a binary image that is encoded into the mask layer and overlaid on the image. The image itself is parsed into a background layer and one or more mask layers comprising different portions of the document. The encrypted mask layer comprising the text string and/or binary image can be generated using the same color as the background layer, such that the document status information is invisible and does not cause unwanted artifacts during printing or conversion of the document between formats. The document status information can be scanner signature information, scan-to-file authentication information, object metadata, etc.
