GENERATING METHOD, VERIFYING METHOD FOR ELECTRONIC BILL WITH ANTI-FAKE TWO DIMENSION (2D) CODE AND SYSTEM FOR SAME

摘要

The present invention relates to methods for generating and verifying an electronic bill with an anti-counterfeiting two-dimensional code and systems of the same. The method of generating an electronic bill with an anti-counterfeiting two-dimensional code of the present invention comprises reading an original electronic bill picture and generating a temporary electronic bill picture with a determined region for embedding two-dimensional code; calculating digest data for the temporary electronic bill picture by using an information digest algorithm and encrypting the obtained digest data to generate an anti-counterfeiting two-dimensional code; and embedding the anti-counterfeiting two-dimensional code into said region of the original electronic bill picture to obtain an electronic bill with the anti-counterfeiting two-dimensional code. Using the present invention can effectively avoid the electronic bill being tampered and forged, and also can greatly enhancing style diversification and practicability of the electronic bill.
