Abstract

In response to a fee payment request issued from an applicant apparatus via a communication network, a payment acceptance server makes a payment credit inquiry of an applicant to a financial institution server. When a payment acceptance server judges that a payment by the applicant is quaranteed, the payment acceptance server transmits to an applicant apparatus, an electronic payment certificate corresponding to a stamp, or an inspection sticker. A document with the payment certificate is transmitted from either the applicant apparatus or an agent apparatus to a document acceptance server via the communication network. Before a main body of the document is received, the document acceptance server receives from the document transmitting apparatus, compressed data which is acquired by applying one-way cryptographic function, and sets this reception timing as acceptance day/time this document.

Claims

1. 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.

2. A document transmit system as claimed in claim 1, wherein said ticket contains at least one of a number allocated by said document acceptance server, information concerning said document transmitting apparatus which transmits said document data, an expiration date and a signature.

3. A data transmit system for transmitting data from a predetermined apparatus to a document acceptance server, comprising:

wherein said predetermined apparatus includes an encryption/decryption processing unit for compressing data to be transmitted to obtain first compressed data, and a document transmit processing unit for transmitting said data, said compressed data and a ticket including information for identifying said compressed data to said document acceptance server;

wherein said document acceptance server includes a storage unit for storing said first compressed data transmitted from said predetermined apparatus, an encryption/decryption processing unit for compressing said data transmitted from said predetermined apparatus to obtain second compressed data, and a document acceptance processing unit for identifying said first compressed data stored in said storage unit from the information contained in said ticket transmitted from said predetermined apparatus, comparing said first compressed data thus identified with second compressed data obtained by said encryption/decryption processing unit of said document acceptance server, and confirming that both said first compressed data and said second compressed data are identical with each other;

wherein said document acceptance server allocates an acceptance number to each first compressed data received from said predetermined apparatus; and

wherein said ticket includes an acceptance number corresponding to said first compressed data received from said predetermined apparatus.

4. A data transmit system as claimed in claim 3, wherein said encryption/decryption processing unit of said predetermined apparatus creates said first compressed data by applying a one-way cryptograph function to said data to be transmitted, and

wherein said encryption/decryption processing unit of said document acceptance server creates said second compressed data by applying a one-way cryptographic function to said data transmitted.

5. A document transmit system as claimed in claim 3, wherein said ticket contains at least one of a number allocated by said document acceptance server, information concerning said predetermined apparatus which transmits said data, an expiration date and a signature.

6. A data transmit method for transmitting data from a predetermined apparatus to a document acceptance server, said method comprising the steps of:

creating, by said predetermined apparatus, first compressed data by applying a one-way cryptographic function to data to be transmitted, and transmitting said first compressed data to said document acceptance server;

receiving, by said document acceptance server, said first compressed data transmitted from said predetermined apparatus, storing said first compressed data thus received, and thereafter transmitting a ticket to said predetermined apparatus,

wherein said document acceptance server allocates an acceptance number to each first compressed data received from said predetermined apparatus, and

wherein said ticket includes an acceptance number corresponding to said first compressed data received from said predetermined apparatus; and

receiving, by said document acceptance server, said data to be transmitted from said predetermined apparatus, creating second compressed data by applying a one-way cryptographic function to said data received from said predetermined apparatus, comparing said second compressed data thus created by said document acceptance server with said first compressed data stored by said document acceptance server, and confirming that both said first and said second compressed data are identical with each other.

7. A data transmit method as claimed in claim 6, wherein said ticket contains at least one of a number allocated by said document acceptance server, information concerning said predetermined apparatus which transmits said data, an expiration date and a signature.

8. A data transmit method for transmitting data from a predetermined apparatus to a document acceptance server, comprising the steps of:

creating, by said predetermined apparatus, first compressed data by applying a one-way cryptographic function to data to be transmitted, and transmitting said first compressed data to said document acceptance server;

receiving, by said document acceptance server, said first compressed data transmitted from said predetermined apparatus, storing said first compressed data thus received, and thereafter transmitting a ticket for identifying said first compressed data thus stored to said predetermined apparatus,

wherein said document acceptance server allocates an acceptance number to each first compressed data received from said predetermined apparatus, and

wherein said ticket includes an acceptance number corresponding to said first compressed data received from said predetermined apparatus;

transmitting, by said predetermined apparatus, said data to be transmitted and said ticket to said document acceptance server; and

receiving, by said document acceptance server, said data to be transmitted, creating second compressed data by applying a one-way cryptographic function to said data received, comparing said second compressed data thus created by said document acceptance server with said first compressed data stored, and confirming that both said first and said second compressed data are identical with each other.

9. A document transmit method as claimed in claim 8, wherein said ticket contains at least one of a number allocated by said document acceptance server, information concerning said predetermined apparatus which transmits said data, an expiration date and a signature.
