Abstract


In recent years the forgery criminal activities are increasing, which makes rapiddevelopment of certificate anti-counterfeiting technology. Currently, specialty materials andspecial processing technology are used in certificate anti-counterfeiting technology, whichleads to increased cost for making a certificate. It seems to be not applicable for ordinarycertificates that the cost is high.Adopting two dimensional barcode is mainly aimed to implement the automaticacquisition of information and increase the ability of credentials anti-counterfeiting. As far asthe technology itself is concerned, two dimensional barcode is not a strictlyanti-counterfeiting technology but a kind of information storage and transmission technology.Therefore, integrating of the two dimensional code technology and digital watermarkingtechnology is one measure that can improve the level of credentials anti-counterfeiting in theanti-counterfeiting field with a special security requirement.This article reads as follows:This article made detailed research on PDF417 encoding technology and made a barcodegeneration system for credentials management by using VB language.In this article, digital watermarking technology based on the PDF417 code issummarized and analyzed, according to credentials management needs, an improvedalgorithm is proposed, and encrypted watermark embedding and detection system is designedand implemented. The simulation confirms that the digital watermarking implemented by thenew algorithm is a fragile watermark, which is comparatively suitable for certificatesanti-counterfeiting.This article does research on the random key technology of pseudo fingerprint characteristics, and the technology is used in two dimensional barcode encoding technologyand watermarking embedding algorithm to achieve the identity of people and credentials incredentials management of certificate management systemThe present problems existing in temporary residence permits management is alsoanalyzed in this article, and the key module of a temporary residence permit managementsystem is designed and realized.
