  • Publication number: 20060031678
    Abstract: A method for unified management of secret key using a signature server is known, however, there is a danger that a hash value and/or signature data are altered in the middle of communication channel between a multi-function device and the signature server. Accordingly, the feature amount of the image data is calculated, and the feature amount is transmitted to a signature server. Then electronic signature data generated from the feature amount by the signature server is received, the received electronic signature data is verified using the feature amount, and if the result of verification indicates that the electronic signature data is proper for the image data, image data with electronic signature, where electronic signature data is added to the image data, is generated.
