Information providing system using code information
First Claim
1. An information-supply system that uses code information comprising:
- a code-issuing server system that encodes part of a character string to generate an encoded portion by a secret key and issues code information that is a combination of the encoded portion and an open portion including a Web address;
an information-supply server system that includes an open-key management server that manages an open key for decoding the encoded portion of said code information and an advertiser server that manages information supplied via a network; and
a portable terminal having an imaging function that uses an imaging element, and that photographs said code information, obtains a Web address that is contained in the open portion by decoding said open portion of said photographed code information, and accesses a Web page via said network using said obtained Web address and sends an encoded portion that is contained in said code information;
wherein said information-supply server system decodes, using said open key, said encoded portion that is sent in response to access from said portable terminal based on a Web address obtained by decoding from said portable terminal and supplies information corresponding to the decoded encoded portion from said advertiser server to said portable terminal via said network.

Abstract
By using code information, it is possible to easily and accurately direct users to interactive media. The code-issuing server system 10 issues 2-dimensional code information according to a request, an advertiser server system 20 receives the issued 2-dimensional code information and an advertiser server 21 manages the received 2-dimensional code information, a portable telephone 30 having an imaging function that uses a CCD camera photographs the 2-dimensional code information, obtains a Web address that is contained in the photographed 2-dimensional code information and accesses a Web page via the Internet 40 using the obtained Web address, and the advertiser server system 20 supplies information to the portable telephone 30 via the Internet 40 in response to access from the portable telephone 30.

10. An information-supply method that uses code information comprising:
-
encoding part of a character string to generate an encoded portion by a secret key and issuing code information that is a combination of that encoded portion and an open portion including a Web address by a code-issuing server system; managing an open key for decoding the encoded portion of the code information by an open-key management server system of an information-supply server system; managing information supplied via a network by an advertiser server of the information-supply server system; and photographing said code information using a portable terminal having an imaging function that uses an imaging element; and obtaining a Web address that is contained in the open portion by decoding the open portion of the photographed code information and accessing a Web page via the network using the obtained Web address and sending an encoded portion that is contained in the code information; wherein the information-supply server system decodes the encoded portion that is sent in response to access from said portable terminal based on a Web address obtained by decoding from the portable terminal by the open key and supplies information corresponding to the decoded encoded portion from the advertiser server to the portable terminal via the network. - View Dependent Claims (11, 12, 13, 14, 15, 16)
