WATERMARK BASED TWO-DIMENSIONAL BARCODE ANTI-FORGERY METHOD AND AN APPARATUS THEREOF CAPABLE OF DISPLAYING A FORGERY PATTERN

摘要

PURPOSE: A watermark based two-dimensional barcode anti-forgery method and an apparatus thereof are provided to confirm forgery without additional device by displaying a forgery pattern on a barcode when a barcode is scanned.;CONSTITUTION: A codeword converting unit(110) converts received data into a codeword. An error verifying code generating unit(120) generates an error verifying code of the codeword. A storage pattern determining unit(130) determines a pattern for storing the error verifying code from a pattern code table. A data matrix generating unit(150) generates a data matrix by rearranging the codeword according to the determined pattern.;COPYRIGHT KIPO 2012
