Embodiment Construction

[0041] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0042] Method of the present invention is characterized in that:

[0043] Encode the detailed information of the product into Chinese Sensible Code, remove its blank area and position detection graphics, and use it as a watermark image, and perform Arnold transformation on this watermark image to scramble. Then, carry out two-stage DWT transformation on the carrier image, embed the scrambled watermark image into the low-frequency sub-band of the image, and then restore the embedded watermark image through two-stage DWT inverse transformation.

[0044]After the above processing, the image information embedded with the watermark is added to the product as an anti-counterfeiting mark, and the anti-counterfeiting processing of the product is completed. The inspection of commodity information is the reverse order of the above steps. Use the detection software to obtai...

Abstract

The invention provides a Chinese-sensible code and digital watermark-based anti-counterfeit method. A Chinese-sensible code is hidden in any number image as watermark information; then a digital image in which a bar code watermark is embedded is added to a relevant position of a commodity to be anti-counterfeited; a detection system extracts and decodes the bar code watermark in the anti-counterfeit image to acquire relevant information on the commodity so as to judge the authenticity of the commodity.

Description

(1) Technical field [0001] The invention relates to an anti-counterfeit method based on Chinese Sensible code and digital watermark. (2) Background technology [0002] With the development of technology, two-dimensional barcodes are widely used in product identification and anti-counterfeiting due to their many outstanding advantages, such as large data capacity, suitable for various occasions, not afraid of folding, easy to carry, and low cost. Through the two-dimensional code anti-counterfeiting system, the encrypted two-dimensional code product information can be generated one by one corresponding to the product, and the two-dimensional code can be printed or labeled on the product packaging, and the user only needs to use the designated two-dimensional code anti-counterfeiting system or mobile phone software for decoding inspection , you can get the authentic safety information of the product. The emergence of anti-counterfeit QR codes provides a simple, convenient and ...
