Focusing on solving the problems of increasing certificate counterfeiting, a novel certificate management system based on two-dimensional barcode technology was developed in the present work. The system, which was compiled using JAVA programming language, can achieve the two-dimensional barcode encoding and decoding for plain texts, images and information included in a certificate (the combined information of texts and images). To improve the security in practical applications, the scrambling algorithm and watermarking encryption algorithm were added, and accordingly, the security of the information contained in two-dimensional barcodes can be ensured. The whole system consists of three modules-encoding, encryption and decoding. To be specific, before encoding, the scrambling transformations should be performed on the certificate image while the number of scrambling transformations is adopted as the secret key. With respect to the generated two-dimensional barcode, we can embed the existing binary images or the signature messages of the certificate holder on this platform into the space domain, contributing to a significantly enhanced anti-counterfeiting performance of the certificate. The certificate information and watermarking information are extracted during the decoding process, i.e., only when the number of scrambling transformations is accurately input, the watermarking information can be extracted and used for identify whether the certificate is counterfeit. The simulation results indicate that, by combing with digital watermarking technology, the security of the two-dimensional barcodes and the included information can be greatly improved while the anti-counterfeiting of certificates can be indeed achieved. Finally, with the student’s certificates as the example, we performed simulations on the whole system. It can be concluded that the developed system can be promoted in the other application fields only when some appropriate changes are made.
