摘要
在纤维成纸过程中,通过在网部上方控制旋转气流通断的方法可使纸浆纤维的排列呈现规律性交织,进而在纸张内部形成纤维规律性交织的图形,以实现数字化加密。在加密过程中,可将存储的信息转换成数字化点阵编码,形成可镶嵌于纸张纤维中的点阵图形。该方法容易变换图案,加密效果独特。
During papermaking,digital encryption on the paper could be realized by controlling rotary air flow over the wire to regularize fiber arrangement and form interweaving patterns. The method was able to convert the stored information into digital dot-array code to form lattice patterns embedded in the fibers. Therefore,it was easy for this method to change interweaving patters and the encryption effect was unique.
