摘　　要：根据对电子商务交易中票据的认证要求,针对电子票据在互联网上传输的特点,提出了一种基于多层数字水印技术的电子图章认证体系,将鲁棒和脆弱的数字水印技术相结合,采用认证中心和客户方双重监督机制,实现电子票据的不可复制、不可伪造、不可抵赖的目的.该体系在满足法律要求的前提下,电子票据通过网络安全快捷地传送给接收方,为实现电子交易提供了技术保障.The transferring characters of E-note on Internet were taken into consideration. According to E-business demand of E-note authentication, an E-note authentication system based on multiple layers digital watermark is presented. Combined fragile with robust digital watermark technology, the authentication mechanism of both CA and the customer was used in the system, to prevent the E-note from being copied illegally, forged and denied.
