Patent number: 9589217Abstract: A system generates a secure barcode by: identifying a primary pattern for a two-dimensional barcode to be printed on a substrate, wherein the primary pattern comprises of a set of dark cells and a set of light cells; identifying a two-dimensional micro-shape, wherein the micro-shape has a size that is no larger than a size of each cell of the two-dimensional barcode; generating a secondary pattern comprising a plurality of the micro-shapes; and superimposing the secondary pattern with the primary pattern for the two-dimensional barcode to yield a secure barcode. The resulting two-dimensional barcode includes a primary pattern comprising a set of dark cells and a set of light cells, where the sets represent encoded data, along with a secondary pattern of micro-shapes that are superimposed with the primary pattern.Type: GrantFiled: July 9, 2014Date of Patent: March 7, 2017Assignee: Xeroc CorporationInventors: Reiner Eschbach, Raja Bala, Saurabh Prabhat, Judith E.

Patent number: 8139270Abstract: A method and system is provided for generating a variable data differential line pattern font comprising forming a periodic line pattern suitable for tessellation disposition within a printed document and selectively distorting a portion of the periodic line pattern in a predetermined manner wherein the distorting comprises generating a distinguishable font corresponding to the distorting. A plurality of different distinguishable fonts are formed by a corresponding plurality of distorted line patterns, respectively.Type: GrantFiled: May 31, 2007Date of Patent: March 20, 2012Assignee: Xerox CorporationInventors: Zhigang Fan, Reiner Eschbach, Judith E.

Patent number: 7787154Abstract: A method and system is provided for providing a variable data guilloché shaped pattern comprised of variable data differential line pattern fonts comprising decodable template symbols which are capable of being selectively assembled into a predetermined variable data code. The code representations are embedded in the guilloché pattern amongst a plurality of unvaried standard base patterns. The representation can be decoded with a digital scan capable of identifying the embedded patterns and communicated it to a user for verifying a document containing the code.Type: GrantFiled: May 31, 2007Date of Patent: August 31, 2010Assignee: Xerox CorporationInventors: Zhigang Fan, Reiner Eschbach, Judith E.

Patent number: 5528386Abstract: In a printer which produces images as a function of the combination of cyan (C), magenta (M), yellow (Y) and black (K) colorants on an output color print, responsive to device independent colorimetric description of an image, there is provided a method of calibrating the response of the printer to an image described in terms of colorimetric values, including the steps of first, gray balancing or linearizing colorant signals; secondly, adding black to an ideal device dependent description of a color image in accordance with a predetermined black addition process, and thirdly, providing a color correction transformation process, where the color correction transformation is accomplished via a method of interpolating printer responses from a look-up table indexing colorimetric descriptions of measured real responses, which take into account subsequent black addition and signal linearization.Type: GrantFiled: January 10, 1994Date of Patent: June 18, 1996Inventors: Robert J.
