Abstract: A rights management system and method allow users to easily associate rights management policies with documents send via email from a client (e.g. a computer or scanner). The client transmits email recipient information, including the attention type (“to,” “cc” or “bcc”) for each recipient, to a rights management server. The server stores multiple rights management policies each specifying access rights (e.g. view, edit, print) granted to specified users, and stores an attention-right rule defining a correspondence between access rights and attention types. Based on the recipient information from the client, and applying the attention-rights rule, the server selects an appropriate policy or creates a new one if an appropriate policy does not exist, and transmits the policy, a document ID and an encryption key to the client. The client encrypts the document, adds metadata to the document, and sends the email with the attached document to a mail server.

Abstract translation: 权限管理系统和方法允许用户轻松地将权限管理策略与通过客户端（例如计算机或扫描仪）的电子邮件发送的文档相关联。 客户端向权限管理服务器发送电子邮件收件人信息，包括每个收件人的注意类型（“至”，“cc”或“密送”）。 服务器存储多个权限管理策略，每个权限管理策略指定授予指定用户的访问权限（例如，查看，编辑，打印），并且存储定义访问权限和注意类型之间的对应关系的注意权限规则。 基于来自客户端的收件人信息，并应用注意权规则，服务器选择适当的策略或者如果相应策略不存在则创建新策略，并将策略，文档ID和加密密钥发送到 客户。 客户端加密文档，向文档添加元数据，并将附带文档的电子邮件发送到邮件服务器。
