基于DCT变换的抗打印扫描电子签章方法
Method Based on DCT transform to Resist Printing and Scanning Attack on Digital Seal
摘要
Abstract
A digital seal method which can resist printing and scanning process is propased to solve the problem of insufficient repellency against printing and scanning attack on the existing digital seal. In combination with the existing electron signature system, the electronic signature is realized by a digital watermarking algorithm of resisting the printing and scanning attack after inserting the signed messages into the specific seal image. The proposed method is more effective to resist the printing and scanning attack on digital seal than the existing methods of digital seal. The experimental results show that the proposed method is feasible.关键词
