Abstract


Digital watermarking is an effective technology to enforce copyright protection of digital products. However, the current vector geographic data characteristics of digital watermark detection research is still relatively weak, far from the formation of the the system detects theory and effective detection methods; the watermark detection only in the infringement occurred suspicious works many restrictions, more serious impact on the promotion and application of digital watermarking technology. This study the the \autonomous detection of geographical data watermarking method, in order to achieve the autonomy of the network on a large number of suspected infringing vector geographic data, real-time watermark detection. Thesis from the three vector geographic data watermarking blind detection watermark independent detection methods and watermark detection Agent Security, the main contents include: (1) in-depth analysis of the watermark detection technology based on vector geographic data characteristics and signal characteristics, research DWT watermark detection based on quantitative way based the statistical variance airspace watermark detection, several different DFT watermark detection based on multiplicative way watermark detection method. (2) based on the Mobile Agent digital watermarking own detection mode, build a prototype system framework and the and watermark detection prototype system development and implementation for the framework. (3) for watermark detection Agent security issues, the paper uses encryption and digital signature technology to improve the security of the host and Agent. Vector geographic data, based on the multiplicative embedded watermark need to consider how to determine the the unified threshold value and the statistical distribution of vector data of two aspects, so that the normalized correlation detection can not be the optimum detection method as multiplied embedded watermark, while based on the statistical variance the method has better robustness and lower data deformation, compared with other algorithms better suited to the application. In addition, the combination of mobile Agent technology watermark detection method can become own watermark detection of a solution in a WAN environment, the Agent using encryption and digital signatures, can improve Remote Agent Host Agent and message security. Papers carried out vector geographic data watermark detection method based on vector geographic data of Mobile Agent watermark autonomous detection mode innovation.
