摘要
为了保证电子商务中票据的在网络中的安全传输,本文提出把票据隐藏于一幅风景图中,但又不明显改变该风景图的视觉效果,起到迷惑黑客和攻击者的目的,增大被破解的难度。本文利用小波变换把电子票据嵌入到中频带中。实验结果表明该方法（信息隐藏或信息伪装）效果好且可用性强。
For transfering securely electronic transaction tickets in network,the method based on information hiding is developed in the paper.Electronic transaction tickets are hidden to image in the method,to cause not attention of hacker and attacker.The tickets are embedded to middle-frequency by wavelet transform.Robustness and imperceptibility of embedded tickets is reconciled automatically in wavelet transform domain.Experiment results shown that this method（information hiding,or,steganography）was useful and applicable.
