Abstract

Provided is a product on which is imprinted an encrypted message obtained by encrypting a message sent along with the product from a sender to a recipient, a method for manufacturing the product, and a system for manufacturing the product. The product manufacturing system has a general web server, an encryption calculating apparatus, an issued encryption values database, a specialized web server, an archive database, and an imprinting apparatus. The product manufacturing system is provided with a message acquiring section that acquires the original message sent along with the product from the sender to the recipient, an encryption calculating apparatus that generates a calculated encryption value by using a hash function to compress a calculation target message extracted from the original message, and an imprinting control section that controls imprinting of the calculated encryption value onto the product.

Claims

1. A method for manufacturing a product that involves encrypting at least a portion of an original message given from a sender to recipient associated with the product and imprinting the encrypted value onto the product, the method being performed by a product manufacturing system and comprising the steps of:

(a) acquiring the original message, by a means of a message acquiring section in the product manufacturing system;

(b) setting at least a portion of the original message to be a calculation target message and acquiring a calculated encryption value by compressing the calculation target message with a hash function, by means of an encryption calculating apparatus in the product manufacturing system; and

(c) imprinting the calculated encryption value onto the product as an imprinted encryption value, by means of an imprinting apparatus in the product manufacturing system.

2. The method according to claim 1, wherein the step (b) includes:

calculating a hash value from the calculation target message, by means of the encryption calculating apparatus;

obtaining an intermediate calculation value by performing an arbitrary function calculation on the hash value, by means of the encryption calculating apparatus; and

calculating the calculated encryption value from the intermediate calculation value, by means of the encryption calculating apparatus.

3. The method according to claim 1, further comprising the steps of:

(d) receiving, by means of a message receiving section in the product manufacturing system, the calculating target message that is at least a portion of the original message sent together with the product, as a confirming message input by the recipient or an inheritor who will inherit the product; and

(e) outputting a confirming calculated encryption value that is identical to the imprinted encryption value, if the confirming message is identical to the calculation target message, by means of the encryption calculating apparatus.

4. The method according to claim 2, further comprising the steps of:

(f) creating a private webpage for receiving an exchange between the sender and the recipient, by means of a private webpage creating section in the product manufacturing system;

(g) outputting a security code that is generated from a calculation result of the step of calculating a hash value and that is different from the calculated encryption value, for verifying an access right to the created private webpage, by means of a security code output section in the product manufacturing system;

(h) receiving, from the sender or the recipient, the security code sent together with the product, by means of a security code receiving section in the product manufacturing system; and

(i) verifying the access right to the private webpage based on the received security code, by means of an authentication section in the product manufacturing system.

5. The method according to claim 2, further comprising the steps of:

(j) archiving data that the sender, the recipient and the inheritor wish to store, by means of the message acquiring section in the product manufacturing system;

(k) creating an inheritance webpage that includes the archived data for each of the sender, the recipient, and the inheritor, by means of an inheritance webpage creating section in the product manufacturing system;

(l) receiving input of an access key for accessing the inheritance webpage, by means of an access key receiving section in the product manufacturing system;

(m) outputting a security code that is generated from a calculation result of the step of calculating a hash value and that is different from the calculated encryption value, for verifying an access right to the created inheritance webpage, by means of a security code output section in the product manufacturing system;

(n) receiving, from the sender, the recipient, and the inheritor, the security code sent together with the product, by means of a security code receiving section in the product manufacturing system; and

(o) verifying the access key with authentication information including the calculated encryption value, based on the received security code, and allowing access to the inheritance webpage and also allowing the archived data to be changed, by means of an authentication section in the product manufacturing system.

8. The method according to claim 2, further comprising the steps of:

(d) receiving, by means of a message receiving section in the product manufacturing system, the calculating target message that is at least a portion of the original message sent together with the product, as a confirming message input by the recipient or an inheritor who will inherit the product; and

(e) outputting a confirming calculated encryption value that is identical to the imprinted encryption value, if the confirming message is identical to the calculation target message, by means of the encryption calculating apparatus.

6. A product manufacturing system that encrypts at least a portion of an original message given from a sender to a recipient associated with a product and imprints the encrypted value onto the product, comprising:

message acquiring section that acquires the original message;

a calculation encryption processing section that sets at least a portion of the original message to be a calculation target message and acquires a calculated encryption value by compressing the calculation target message with a hash function; and

an imprinting apparatus that imprints the calculated encryption value onto the product as an imprinted encryption value.

7. A product that is sent from a sender to a recipient and on which is imprinted an imprinted encryption value obtained by encrypting, with a hash function, at least a portion of an original message given from the sender to the recipient associated with the product.
