Abstract: A method of printing a document (10) stored at a home computing system (5) on a printer (9) of a remote computing system, the home and remote computing system including a home trusted print proxy (HTPP) (3) and a remote trusted print proxy (RTPP) (2), respectively, which are configured to be able to establish communication via a communications link, in which the printer (9) includes a digital identification device (1) configured to provide a printer public key of a cryptographic public key/private key pair and the RTPP (2) is configured to supply a one time token on request, the method including the steps of using a mobile device (4) to interrogate the RTPP (2) and printer (9) to obtain a one time token and the printer public key using the mobile device (4) to transmit to the home computing system (5) a print request including the one time token and printer public and identification of the document (10) to be printed establishing a secure communications channel between the home and remote computing system via at least the HTPP and RTPP the home computing system (5) transmitting the document encrypted by the printer public key to the printer (9) via the secure communications channel and the printer (9) decrypting the encrypted document and initiating printing of the document only if the mobile device is in communication with the printer (9).

Abstract translation: 一种在家庭计算系统（5）上存储在远程计算系统的打印机（9）上的文档（10）的方法，所述家庭和远程计算系统包括家庭可信打印代理（HTPP）（3）和 远程可信打印代理（RTPP）（2），其被配置为能够经由通信链路建立通信，其中打印机（9）包括数字识别装置（1），其被配置为提供打印机公钥 密码公钥/私钥对和RTPP（2）被配置为根据请求提供一次令牌，该方法包括以下步骤：使用移动设备（4）询问RTPP（2）和打印机（9） 使用所述移动设备（4）获得一次令牌和所述打印机公钥，以向所述家庭计算系统（5）传送包括所述一次令牌和打印机公开的打印请求以及要打印的所述文档（10）的标识 建立一个安全通信系统 至少通过HTPP和RTPP将家庭计算系统（5）通过安全通信信道传送到打印机（9）的家庭计算系统（5），打印机（9）将家庭和远程计算系统（5）传送到打印机 加密文档，并且仅当移动设备与打印机通信时才开始打印文档（9）。
