Embodiment
Illustrate that compound Quick Response Code of the present invention is specifically described below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the compound Quick Response Code of the present embodiment.
As shown in Figure 1, compound Quick Response Code 100 is a kind of compound Quick Response Codes that the present embodiment provides.This compound Quick Response Code comprises:
Carrier Quick Response Code, for carrying general information;
Watermark Quick Response Code, embeds in described carrier Quick Response Code by watermark embedment mode, for carrying the information different from described carrier Quick Response Code.
Watermark embedment mode in compound Quick Response Code can be LSB, DCT, DWT, holographic watermark method and other watermark embedding methods (it is all carry out combining and furtheing investigate based on above classic algorithm that watermark embedding method is much studied).Here for LSB watermark embedding method, set forth.
Fig. 2 is the product process figure of the compound Quick Response Code of the present embodiment.
As shown in Figure 2, the compound Quick Response Code 100 in the present embodiment generates based on LSB digital watermark.
General information is generated Quick Response Code as carrier Quick Response Code by algorithm by step S1, and this Quick Response Code can realize all user's indifference barcode scannings;
Private information is generated another Quick Response Code as watermark Quick Response Code by algorithm by step S2;
Step S3 is by 8 bit images (if carrier Quick Response Code is 2 bit images, being first converted into 8 bit images) the lowest order plane zero setting of carrier Quick Response Code;
Step S4 is combined watermark Quick Response Code and carries out watermark scramble and obtain the watermark Quick Response Code after scramble with random scrambling template;
Watermark Quick Response Code after scramble is embedded the lowest order plane of carrier Quick Response Code by step S5, realizes the embedding of watermark, obtains compound Quick Response Code 100.
