图7是根据本公开一个实施例的办公方法的流程图。
如图7所示，本公开实施的办公方法可以应用于本公开提供的办公设备600a或办公设备600b。办公方法可以包括操作S710至操作S740。
在操作S710，在获得访问者授权的情况下，通过摄像头、显示器或音频装置获取访问者的身份信息。
例如，在获得访问者授权的情况下，通过摄像头获取访问者的人脸信息，以为访问者进行人脸识别。
在操作S720，在确定访问者的身份信息通过验证的情况下，响应于访问者的请求，利用数据处理设备通过第一节点识别访问者的访问权限。
例如，在通过人脸识别确认访问者内部员工的情况下，允许访问者使用办公设备。办公设备上可以安装有办公应用程序。访问者在办公设备上的办公应用程序中提交访问请求。例如，访问请求可以是查看某一业务项目内容。
第一节点可以是访问者的登录节点，可以通过识别第一节点的ip地址确定访问者的访问权限。
在操作S730，在确定请求与访问权限匹配的情况下，利用数据处理设备在第一节点为访问者启动办公服务。
在操作S740，在确定请求与访问权限不匹配的情况下，利用数据处理设备控制第一节点向第二节点发送请求，使第二节点处理请求。
例如，第一节点与第二节点分别与终端相连，第二节点的访问权限大于第一节点的访问权限。访问者可以通过与第一节点或第二节点连接的终端使用办公设备。办公设备可以是安装在终端中；也可以是安装在终端之外，办公设备与终端通过有线或无线的方式连接。
在通过第一节点登录办公设备的访问者没有访问权限时，可以向第二节点发出申请。在接收到第二节点发送的准许指示后，访问者可以通过第一节点访问相应的业务项目内容。第一节点和第二节点可以分别与数据库相连，第一节点和第二节点可以与相同的数据库相连，也可以与不同的数据库相连。通过数据库与具有不同优先级的节点相连，可以控制不同节点对数据库的访问，保证数据的安全性与时效性。通过第一节点访问者还可以自动进入工作流程环节，减少工作安排流程，有效节省时间，实现自动化办公，可以通过远程激活电脑，打印机等等办公设备。
在本公开实施例中，在操作S730在确定请求与访问权限匹配的情况下，利用数据处理设备在第一节点为访问者启动办公服务的步骤可以包括：利用数据处理设备通过第一节点向第二节点发送业务项目；利用数据处理设备通过第二节点向第一节点发送与业务项目相关的反馈结果；在确定反馈结果为业务项目通过审核的情况下，利用数据处理设备通过第二节点处理业务项目；以及在确定反馈结果为业务项目不通过审核的情况下，利用数据处理设备通过第一节点调整业务项目，并返回执行利用数据处理设备通过第一节点向第二节点发送业务项目的操作，直至审核通过或业务项目结束。
在本公开实施例中，第一节点和第二节点通过内部通信节点进行数据传输。具有更高权限的第二节点发布业务项目，并向第一节点发送业务项目的作业内容。第一节点和第二节点可以通过内部通信节点进行数据传输，以确定项目等级、项目需求、项目方案内容等信息。第二节点可以作为审核节点对第一节点提交的内容进行逐次审核，以对项目进行调整。通过迭代的方式在第一节点和第二节点之间进行数据交互，推动项目进展。
在本公开实施例中，在操作S710～S740的基础上，办公方法还包括：利用数据处理 设备通过第一节点读取待处理数据和密钥，待处理数据包括从公网接收的数据；利用数据处理设备在第一节点，根据密钥对待处理数据进行解码，得到解密数据；以及利用数据处理设备在确定第一节点无权限接收解密数据的情况下，将解密数据发送给第二节点，使第二节点接收解密数据。
在操作S710～S740的基础上，办公方法还包括：利用数据处理设备通过第一节点获取原始数据和密钥，原始数据包括向公网发送的数据；利用数据处理设备在第一节点，根据密钥对原始数据进行编码，得到加密数据；以及在确定第一节点无权限发送加密数据的情况下，利用数据处理设备将加密数据发送给第二节点，使第二节点发送加密数据。
在本公开实施例中，第一节点和第二节点还可以分别通过通信节点与公网进行数据交互。通信节点可以是办公设备连接的服务器。在与公网的数据进行交互时，需要对交互数据进行加密传输，以保证数据安全性。
第一节点和第二节点均在内网对数据进行加密与解密，使得在公网传输的数据均为加密数据，防止信息的泄露。数据的解码与编码都需要有一套相应的加密与解密系统，防止数据被破译。例如，在接收到公网发送的数据就，读取数据并加入密钥，对数据进行解码，解码成功进行数据接收。如果第一节点在对数据解码后，确定无权限访问该数据，第一节点可以通过内部通信节点向第二节点发起数据校验，在接收到第二节点发送的校验通过的指令后，再次进行解码。第一节点也可以将无权限接收的数据发送给第二节点，由第二节点执行解码和接收数据的操作。
图8是根据本公开一个实施例的办公装置的框图。
如图8所示，该装置800包括获取模块810、第一确定模块820、第二确定模块830和第三确定模块840。
获取模块810，用于在确定访问者的身份信息通过验证的情况下，响应于访问者的请求，利用数据处理设备通过第一节点识别访问者的访问权限。
第一确定模块820，用于在确定访问者的身份信息通过验证的情况下，响应于访问者的请求，利用数据处理设备通过第一节点识别访问者的访问权限。
第二确定模块830，用于在确定请求与访问权限匹配的情况下，利用数据处理设备在第一节点为访问者启动办公服务。
第三确定模块840，用于在确定请求与访问权限不匹配的情况下，利用数据处理设备控制第一节点向第二节点发送请求，使第二节点处理请求。
