【摘要】：產(chǎn)品是企業(yè)生產(chǎn)的基本要素,產(chǎn)品流通監(jiān)管系統(tǒng)是加強(qiáng)企業(yè)對(duì)產(chǎn)品流通的信息掌握、完善產(chǎn)品流通可監(jiān)管網(wǎng)絡(luò)化建設(shè)工程。以數(shù)據(jù)庫技術(shù),網(wǎng)絡(luò)技術(shù)和信息技術(shù)為支撐,圍繞“生產(chǎn)-庫存-銷售-售后”的產(chǎn)品流通主線,對(duì)產(chǎn)品流通的各個(gè)環(huán)節(jié)實(shí)施數(shù)據(jù)采集,以產(chǎn)品的二維碼標(biāo)簽為信息載體,實(shí)現(xiàn)對(duì)產(chǎn)品流通信息的可追溯,從而提高企業(yè)的信息化水平。 隨著數(shù)字媒體技術(shù)的飛速發(fā)展,3D (3Dimensions)視頻廣告因能夠提供更加逼真的視覺場景,更加生動(dòng)、形象的展示產(chǎn)品而受到企業(yè)的青睞。數(shù)字水印技術(shù)作為一種有效的信息保護(hù)手段,可以通過一定的算法將特定的信息嵌入到需要被保護(hù)的數(shù)字視頻中來達(dá)到對(duì)企業(yè)3D廣告視頻進(jìn)行版權(quán)保護(hù)的目的。 企業(yè)面臨的一個(gè)問題就是非法廠家生產(chǎn)假冒偽劣產(chǎn)品以次充好、謀取暴利,損害企業(yè)和消費(fèi)者的利益。本文對(duì)企業(yè)的業(yè)務(wù)流程進(jìn)行分析后,提出運(yùn)用密碼技術(shù)給二維碼標(biāo)簽內(nèi)容進(jìn)行加密,消費(fèi)者使用智能手機(jī)拍攝二維碼標(biāo)簽,通過內(nèi)置軟件來完成真?zhèn)悟?yàn)證,設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)產(chǎn)品流通監(jiān)管系統(tǒng)。 這個(gè)系統(tǒng)的主要工作是結(jié)合企業(yè)需求,設(shè)計(jì)了一個(gè)基于B/S(Browser/Sever,瀏覽器/服務(wù)器)架構(gòu)的產(chǎn)品流通監(jiān)管體系,系統(tǒng)不僅滿足企業(yè)對(duì)于產(chǎn)品流通環(huán)節(jié)的信息化管理和企業(yè)對(duì)產(chǎn)品進(jìn)行防偽保護(hù)的需求,同時(shí)對(duì)于企業(yè)的3D視頻資料版權(quán)保護(hù)進(jìn)行了研究和應(yīng)用。本系統(tǒng)的創(chuàng)新之處在于運(yùn)用密碼技術(shù)對(duì)二維碼標(biāo)簽進(jìn)行加密,降低企業(yè)成本、實(shí)現(xiàn)安全防偽；同時(shí)提出一個(gè)新的基于小波域3D視頻幀水印算法,實(shí)現(xiàn)對(duì)企業(yè)3D視頻資料的版權(quán)保護(hù)。該算法首先對(duì)3D視頻幀(立體圖像對(duì))劃分子圖像,將水印嵌入在小波變換后的低頻子帶,仿真實(shí)驗(yàn)結(jié)果表明在滿足本系統(tǒng)對(duì)于水印嵌入后透明性的前提下,降低水印檢測的誤碼率,提高魯棒性。 最后,完成對(duì)系統(tǒng)的性能測試,并且對(duì)系統(tǒng)的性能進(jìn)行了測試和分析,針對(duì)本系統(tǒng)的關(guān)鍵技術(shù)二維碼掃描性能與3D視頻版權(quán)認(rèn)證性能也給出測試結(jié)果,對(duì)今后的研究和改進(jìn)方向進(jìn)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.
