A Technology of Printing Forgery Prevention for Certificates Based on Fingerprint Information

Abstract:

A new method of printing forgery prevention for certificates is proposed after researching on various algorithms of digital watermarking technology, fingerprint recognition technology, watermarking technology, encryption, and digital printing technology. The fingerprint image of the certificate owner is regarded as a watermarking and inserted in the certificate carrier. The encrypted fingerprint holographic watermarking techique is applied to increase the safty of the certificate information and realize the forgery prevention. The certificate presswork which has the encrypted fingerprint holographic watermarking information is printed by the printer. In the identification process, an ordinary scanner is employed to input certificate image information. We can use the obtained decryption keys to extract the watermark information by blind digital watermarking extracting method. The fingerprint collected on site is authorized by the extracting fingerprint information. By combining digital watermarking with fingerprint recognition technology, we realized safe authentication of user’s identity with imperceptibility of digital watermarking and the uniqueness of fingerprint recognition. This technology has some advantages. It is simple in information collecting and generating method, low in facturing cost and high in safe authentication. It has some practical application value.
