An image forming apparatus for attaching an electronic signature to image data read from a paper document is disclosed. Validity of a first public key certificate that certifies a first signature key is determined. A first electronic signature-for the image data is generated by using the first signature key. The first electronic signature is prevented from being generated in response to an event that it is determined that the first public key certificate is invalid.

Image forming apparatus for generating electronic signature

An image forming apparatus configured to generate image data by reading information in a paper, includes a machine signature generation part configured to generate a first electronic signature for the image data by using a secret key peculiar to the image forming apparatus, and an operator signature generation part configured to generate a second electronic signature for the image data by using a secret key peculiar to an operator of the image forming apparatus.

A method of certifying the existence of electronic information released on a network at a time and date. The network connects one or more computer servers and a plurality of client computers with each other. Electronic information of a web page stored in one of the plurality of client computers is accessed using information of its location from one of the computer servers based on a request from one of the client computers. A copy of the electronic information is then obtained. Attribute information is generated from the location, access time, and date when the electronic information is accessed. An electronic certificate may be generated by uniquely specifying the electronic information and the attribute information as inherent information identifying the electronic information. The copy of the electronic information is stored in a memory by tying up the electronic information with the electronic certificate and the attribute information. At least the electronic certificate, the attribute information, and preferably the copy of the electronic information can also be read and provided from the memory to the one of the client computers or its operator as a requester.
