SYSTEM TO INSTANTLY GENERATE AN ONLINE IMAGE OF A DOCUMENT FROM MULTIPLE IMAGES CAPTURED THROUGH A CAMERA EQUPPED MOBILE DEVICE

Grant Date :13/05/2014

Int Patent Classific Num :H04N 1/40

Inventers : Virender Jeet, Sanjay Kalra, Pramod Kumar, Dinesh Ganotra, Sorabh Kumar

Abstract

A method and system is provided for generating a composite document from part images captured through a mobile camera. A user captures multiple images of a document using the camera of his mobile device, covering all the contents of the document. Once the entire desired content has been captured through the multiple images, all these images are sent to an application server, using suitable communication service. At the application server these individual images are juxtaposed, matched for overlapping regions and stitched to form the original document intended. The document image is then sent either to the mobile phone of the original user or sent to any other business application as desired by the original user.

METHOD AND SYSTEM FOR DOCUMENT AUTHENTICATION

Grant Date : 21/10/2013

Int Patent Classific Num :G07D 7/00

Inventers : Pramod Kumar, Virender Jeet, Dinesh Ganotra, Puja Lal, Lalit Kumar, Abhishek Aggarwal, Tavneet Batra

Abstract

A method and system for document authentication to distinguish between an original document and subsequently reproduced copies of the original document by comparing the image of original document with that of the presented copy. A security mark, embedded in the document image, is used to derive and conclude whether the presented document is original or counterfeit. The security parameters extracted from the security mark on the document. These parameters are used for authenticating documents.
