Patent ID: 6868402

Claim:
A document transmit system wherein a document is transmitted from a predetermined apparatus via a network to a document acceptance server, comprising: a document transmit processing unit for applying an one-way cryptographic function to document data to be transmitted so as to obtain first compressed data in a document transmitting apparatus, and then transmitting said first compressed data to said document acceptance server; a ticket issue processing unit for transmitting a ticket to said document transmitting apparatus after receipt of said first compressed data and storage of said first compressed data into a storage apparatus by said document acceptance server, wherein said document acceptance server allocates an acceptance number to each first compressed data received from said document transmitting apparatus, and wherein said ticket includes an acceptance number corresponding to said first compressed data received from said document transmitting apparatus; a document transmit processing unit for transmitting said document data to be transmitted to said document acceptance server after the ticket is received by said document transmitting apparatus; and a document acceptance processing unit for receiving said document data, applying said one-way cryptographic function to said document data so as to obtain second compressed data, comparing said second compressed data with said first compressed data which is stored in the storage apparatus after said document data is received by said document acceptance server, and confirming that said first compressed data is identical with said second compressed data.
