摘要
新闻编辑从发明者提供的背景信息中获得了以下引文：“当虚拟证书号码可以与商家相关联时，虚拟证书号码可以用于增强交互(例如交易)安全性。例如，当顾客使用浏览器扩展时，虚拟证书号码可以与商家相关联，该扩展可以识别与客户生成虚拟证书号码的网站相关的商家，然而，传统的用于当面购物的虚拟证书号码生成技术即使不是不可能，也比较困难，因此生成的虚拟证书号码可能不绑定到特定的商家，这可能会导致虚拟证书号码容易被欺诈。
Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Virtual certification numbers may be used to in crease interaction (e.g., transaction) security when they can be associated with a merchant. For example, a virtual certification number may be associated with a merchant when a customer is using a browser extension, and the extension can r ecognize the merchant associated with the website for which the customer generat ed the virtual certification number. However, conventional techniques for genera ting virtual certification numbers for in-person shopping is more difficult, if not impossible. As a result, generated virtual certification numbers may not be bound to specific merchants, which may leave virtual certification numbers susce ptible to fraud.
