摘要
An original creating apparatus and an originality guaranteeing apparatus prevent a document and a signature from being falsified while visually displaying the signature, etc. For example, time data (t1) is added to data of a document (development plan document) and data of a seal column of a creator, an electronic signature is put, and a checksum (CS1) is geenrated. Then, an original file including also the checksum (CS1) is created, and transmitted to an approver side. The approver side verifies the checksum (CS1), makes a comparison between the checksum (CS1) obtained as a result of the verification, and the checksum recorded to the file, and whether or not both of the checksums match is determined, so that the originality is confirmed. With such a configuration, the presence/absence of falsification can be verified, whereby a document transfer can be visually made while guaranteeing the originality of document data.
