摘要/Abstract

摘要： 电子商务的交易环境安全与否决定了其总体发展程度，而今传统意义上的安全认证方式已经无法完全保证交易的可靠性。因此提出一种以滚动指纹作为认证介质，并进行指纹数字签名的电子商务安全认证方法：将连续滚动指纹帧通过滚动指纹序列无缝拼接算法得到完整的指纹图像，继而提取得到指纹特征作为数字签名的密钥，进行信息传输并验证信息内容的正确性和发送者身份的合法性。实验结果表明，滚动拼接算法能确保任意方向滚动的指纹图像序列都可以拼接得到高质量指纹图像，并且算法复杂度低，能保证进行实时拼接；利用滚动指纹作为认证介质很好地保证了电子商务“认证到人”的认证宗旨。

Abstract: The security of E-commerce determines its development; however, traditional means of security certification cannot meet the demand on reliability. To ensure the security in E-commerce communication, a new method of security certification was proposed based on rolled fingerprint reconstruction and digital signature. Firstly, the image sequence of rolling fingerprints was reconstructed into a high-quality complete fingerprint image, and then the features were extracted as the key of digital signature. Thirdly, the message embedded with digital signature was transferred. At the same time, the correctness and completeness of the message were checked, and the validity of the sender was also identified. The experimental results show that the proposed algorithm can be used for rolling fingerprint reconstruction in any direction to get a high-quality fingerprint image. And it can run in real-time because of low complexity. The rolling fingerprint, as the security certification medium, ensures the security of E-commerce.

Key words: E-commerce, roll fingerprint reconstruction, digital signature, security authentication
