便携式票据数字水印检测系统的研究

摘要

针对目前市场上的票据版权检测缺乏针对性等问题,提出了一种利用手持设备进行票据水印检测的方案.该方案将待检测票据的图像信息通过GPRS无线通信网络上传至远程专用PC机进行水印检测,并在手持设备上显示检测结果.详细介绍了检测系统的总体架构和上下位机的设计方法.试验表明,该方案对票据的数字水印检测具有较高的可靠性和实时性,给票据版权检测带来了极大的便利,具有广阔的应用前景.%The detection for notes copyright currently on the market is still not perfect, aiming at this problem, the detection strategy for notes watermark by adopting handheld device is proposed. The image information of the notes detected is uploaded to the dedicated remote PC via GPRS wireless network for watermark detecting, and the result is displayed on handheld device. The overall framework of the detection system, the design of the device and host PC are introduced. The experiments indicate that the strategy features high reliability and good real time performance in detection of notes digital watermark, thus brings people great convenience. It possesses broad application prospects.
