高密度图形码及其数字水印技术的研究

通过开发一种高密度的二维图形码技术，实现了信息密度更高的印刷存储，用于解决大规模生产流程中，由于产品标志信息量的不断增加而产生的信息存储困难的问题。在高密度图形码中嵌入数字水印，使它在拥有大数据存储容量的同时，又更好地满足了信息安全要求。

Research of Watermark Technology on High-density 2D Symbol

Through developing a kind of technology of High-density 2D Symbol, have realized that the printing of the information with higher density for information stored. Using it for solving the information store problem due to information increase of sign in a large-scale production flow. Through imbedding the watermark in the high-density 2D symbol ones it while having large data memory capacity, and it satisfying the information safety.
