摘要： A facsimile system and method provides authentication of transmitted image information, which authentication may be in the form of a signature page. An authentication device computes authentication information at a sending device, a receiving device, both, or at a remote location during transmission. The signature page may also be transmitted with the document. The sending and receiving devices may each generate signature pages or acknowledgement of receipt in response to receiving a signature page. The authentication information may be encrypted with a public/private key pair. The authentication information may be in the form of a checksum, and may be prepared based on separate regions of the document. A previously generated signature page is compared to a newly generated signature page to verify the document content or authenticity. Document authentication signatures may include machine-readable symbols to represent the authentication information.

摘要翻译： 传真系统和方法提供所传送的图像信息的认证，该认证可以是签名页面的形式。 认证装置在发送装置，接收装置，两者或在发送期间的远程位置处计算认证信息。 签名页面也可以与文档一起传输。 发送和接收设备可以分别响应于接收到签名页面而生成签名页面或收到确认。 认证信息可以用公钥/私钥对加密。 认证信息可以是校验和的形式，并且可以基于文档的单独区域来准备。 将先前生成的签名页面与新生成的签名页面进行比较，以验证文档内容或真实性。 文档认证签名可以包括用于表示认证信息的机器可读符号。
