    • Provided is an image forming apparatus control method which, when an image is to be formed from image data with a digital signature, safely manages the image formed from the image data even if it is impossible to certify whether the image data is tampered. When receiving a request for formation of an image of image data with a digital signature from a personal computer, this image input/output apparatus requests a digital signature issue/authentication server to certify the authenticity of the signature data. On the basis of the certification result, the apparatus adds, to the output image, an additional image indicating that the original image is tampered, or an additional image indicating that whether the original image is tampered cannot be certified.
    • 提供了一种图像形成装置控制方法,即使不能够证明图像数据是否被篡改,当图像要由具有数字签名的图像数据形成时,也可以安全地管理由图像数据形成的图像。 当从个人计算机接收到用数字签名形成图像数据的图像的请求时,该图像输入/输出装置请求数字签名问题/认证服务器来证明签名数据的真实性。 在认证结果的基础上,该装置向输出图像添加指示原始图像被篡改的附加图像,或者表示原始图像是否被篡改的附加图像不能被认证。
