【摘要】：产品是企业生产的基本要素,产品流通监管系统是加强企业对产品流通的信息掌握、完善产品流通可监管网络化建设工程。以数据库技术,网络技术和信息技术为支撑,围绕“生产-库存-销售-售后”的产品流通主线,对产品流通的各个环节实施数据采集,以产品的二维码标签为信息载体,实现对产品流通信息的可追溯,从而提高企业的信息化水平。随着数字媒体技术的飞速发展,3D (3Dimensions)视频广告因能够提供更加逼真的视觉场景,更加生动、形象的展示产品而受到企业的青睐。数字水印技术作为一种有效的信息保护手段,可以通过一定的算法将特定的信息嵌入到需要被保护的数字视频中来达到对企业3D广告视频进行版权保护的目的。企业面临的一个问题就是非法厂家生产假冒伪劣产品以次充好、谋取暴利,损害企业和消费者的利益。本文对企业的业务流程进行分析后,提出运用密码技术给二维码标签内容进行加密,消费者使用智能手机拍摄二维码标签,通过内置软件来完成真伪验证,设计并实现了一个产品流通监管系统。这个系统的主要工作是结合企业需求,设计了一个基于B/S(Browser/Sever,浏览器/服务器)架构的产品流通监管体系,系统不仅满足企业对于产品流通环节的信息化管理和企业对产品进行防伪保护的需求,同时对于企业的3D视频资料版权保护进行了研究和应用。本系统的创新之处在于运用密码技术对二维码标签进行加密,降低企业成本、实现安全防伪；同时提出一个新的基于小波域3D视频帧水印算法,实现对企业3D视频资料的版权保护。该算法首先对3D视频帧(立体图像对)划分子图像,将水印嵌入在小波变换后的低频子带,仿真实验结果表明在满足本系统对于水印嵌入后透明性的前提下,降低水印检测的误码率,提高鲁棒性。最后,完成对系统的性能测试,并且对系统的性能进行了测试和分析,针对本系统的关键技术二维码扫描性能与3D视频版权认证性能也给出测试结果,对今后的研究和改进方向进行了展望。
[Abstract]:Product is the basic factor of enterprise production, product circulation supervision system is to strengthen the enterprise to the product circulation information grasp, perfect the product circulation may supervise the network construction project, with the database technology, the network technology and the information technology as the support, Focusing on the main line of product circulation of "production-inventory, market-after-sale", the data collection is carried out in every link of product circulation, and the information carrier of product's QR code label is used to realize the traceability of product circulation information. In order to improve the level of enterprise information. With the rapid development of digital media technology, 3D 3D Dimensions) video advertising has been favored by enterprises because of its ability to provide more realistic visual scenes, more vivid and vivid display products. Digital watermarking technology is an effective means of information protection. We can embed the specific information into the digital video which needs to be protected by certain algorithm to achieve the purpose of copyright protection of 3D advertising video. One of the problems faced by enterprises is that illegal manufacturers produce fake and shoddy products in order to obtain huge profits and harm the interests of enterprises and consumers. After analyzing the business processes of enterprises, This paper proposes to encrypt the content of QR code label by using cryptography technology. Consumers use smart phone to shoot QR code tag. Through built-in software to complete authenticity verification, a product circulation supervision system is designed and implemented. The main work of this system is to design a product circulation supervision system based on B / S browser / Server (browser / Server) architecture combined with the needs of enterprises. The system not only meets the needs of the enterprise for the information management of the product circulation link and the anti-counterfeiting protection of the enterprise, At the same time, the copyright protection of 3D video data is researched and applied. The innovation of this system is to use cryptography to encrypt the QR code label, reduce the cost of the enterprise, and realize the security and anti-counterfeiting. At the same time, a new 3D video frame watermarking algorithm based on wavelet domain is proposed to protect the copyright of enterprise 3D video data. The watermark is embedded in the low frequency subband after wavelet transform. The simulation results show that under the premise of satisfying the transparency of the system, the bit error rate of watermark detection is reduced and the robustness is improved. Finally, the performance test of the system is completed, and the performance of the system is tested and analyzed. The test results are also given for the key technologies of the system, namely, the scanning performance of the QR code and the performance of 3D video copyright authentication. The future research and improvement are prospected.
