摘要
随着信息时代的到来,信息安全已经成为全球关注的热点问题。打印作为最常用的信息共享方式之一,在给人们工作生活提供极大便利的同时,由于打印带来的信息泄密也给企事业单位造成了不可估量的损失。针对打印安全问题,设计的安全打印机采用了ARM Cortex-A8处理器S5PV210作为硬件平台,Linux作为软件平台,实现了二维码生成,二维码水印的嵌入,打印审计,打印控制以及打印记录的功能。系统通过向涉密文件中嵌入二维码水印信息可以做到打印文档的后期追踪和回收,实现了整个打印流程的闭环处理。
With the arrival of information era,information security has become a hot issue with global concerns. As one of the most commonly used means of information sharing,printing brings huge convenience to our work and daily life,but also causes immeasurable losses to the enterprises and institutions due to information leakage brought about by it. To solve the problem of printing security,the safe printer we designed uses S5PV210 of ARM Cortex-A8 processor as the hardware platform,and Linux as software platform,it implements the functions of two-dimensional code generation,two-dimensional code watermark embedment,print audit,print control and print recording. The system can achieve late track and retrieval of the printing files through embedding 2D watermark information into the classified files and thus realises the closed-loop treatment of entire printing process.
