Abstract
Abstract A mark management server (103) embeds a mark ID and so on in a specified mark image in response to a mark request from a WWW server (102), registers information related to a Web page corresponding to this mark ID in a mark management DB (2021), and sends the mark embedded with the information to the server (102). The server (102) attaches this mark to a created Web page, and registers the Web page in a Web page DB (3021). A client terminal (101) acquires a Web page from the server (102), reads information embedded in a mark, and issues a request for a search according to the mark to the server (103). The server (103) references the DB (2021), and sends information associated with a Web page corresponding to a specified mark ID to the terminal (101).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An information search processing method for
registering information related to multimedia data having
code information associated therewith in a database
(2021), said method comprising the steps of: (a) in response to a request from the outside,
embedding perceptually unrecognizable code information in
perceptually recognizable fixed-pattern data mounted in
multimedia data including at least one of character data,
still image data, moving image data and audio data, and
sending the multimedia data embedded with the code
information to a requester (102); (b) registering information related to said
multimedia data mounted with said code information in the
database, in correspondence to said code information; and (c) in response to a search request from the
outside, searching said database based on specified code
information to extract information on said multimedia
data corresponding to the specified code information, and
sending the extracted information to a requester.
Claim 2
Dependent Claim
29 words
An information search processing method
according to claim 1, wherein said fixed-pattern data,
embedded with said code information, is a mark image in
the form of a still image.
Claim 3
Dependent Claim
126 words
An information search method for requesting to
search for associated multimedia data based on
perceptually unrecognizable code information embedded in
perceptually recognizable fixed-pattern data mounted in
multimedia data including at least one of character data,
still image data, moving image data and audio data, said
method comprising the steps of: (a) decoding said code information embedded in
said fixed-pattern data related to the multimedia data; (b) issuing a search request for information
related to the associated multimedia data to an external
processing unit (103) based on said code information,
said external processing unit having information related
to the associated multimedia data corresponding to said
code information as a database (2021); and (c) displaying acquired information related to
the associated multimedia data on a display device (403).
Claim 4
Dependent Claim
109 words
An information search processing method for
requesting to search for associated multimedia data based
on visually unrecognizable code information embedded in a
visually recognizable mark image mounted in multimedia
data including at least one of character data, still
image data, moving image data and audio data, said method
comprising the steps of: (a) displaying said mark image on a display
device (403); (b) issuing to an external processing unit
(103) a search request for information related to the
associated multimedia data based on said code information
embedded when said mark image was specified; and (c) displaying acquired information related to
the associated multimedia data on a display device (403).
Claim 5
Dependent Claim
302 words
An information search system having a first
server (102) for providing multimedia data including at
least one of character data, still image data, moving
image data and audio data, a client terminal (101) for
receiving the multimedia data provided by said first
server, and a second server (103) for embedding
perceptually unrecognizable code information in
perceptually recognizable fixed-pattern data mounted in
the multimedia data and for managing information related
to the multimedia data mounted with said code
information, wherein: said first server includes means (30141)
responsive to a request from said client terminal for
sending specified multimedia data to said client
terminal, means (30144) for requesting said second server
to send said fixed-pattern data embedded with said code
information, and means (30143) for mounting said fixed-pattern
data in corresponding multimedia data; said second server includes means (20143)
responsive to a request from said first server for
mounting specified code information in specified fixed-pattern
data and sending the fixed-pattern data to said
first server, means (20143) for registering information
related to multimedia data mounted with said code
information in a database, and means (20141) responsive
to a search request from said client terminal for
searching said database based on specified code
information to extract information related to multimedia
data corresponding to the specified code information and
sending the extracted information to said client
terminal; and said client terminal includes means (40141) for
requesting said first server to acquire the multimedia
data mounted with the fixed-pattern data, means (40143)
for decoding code information embedded in acquired fixed-pattern
data, means (40143) for issuing to said second
server a search request for information related to
multimedia data associated with the code information
based on the decoded code information, and means (40143)
for displaying acquired information related to the
associated multimedia data on a display device (403).
Claim 6
Dependent Claim
150 words
A computer program embodied on a computer-readable
medium to perform method steps for registering
in a database (2021) information related to multimedia
data having code information associated therewith, said
method steps comprising the steps of: (a) in response to a request from the outside,
embedding perceptually unrecognizable code information in
perceptually recognizable fixed-pattern data mounted in
multimedia data including at least one of character data,
still image data, moving image data and audio data, and
sending the multimedia data embedded with the code
information to a requester (102); (b) registering information related to said
multimedia data mounted with said code information in the
database, in correspondence to said code information; and (c) in response to a search request from the
outside, searching said database based on specified code
information to extract information on said multimedia
data corresponding to the specified code information, and
sending the extracted information to a requester.
Claim 7

method steps comprising the steps of: (a) decoding said code information embedded in
said fixed-pattern data related to the multimedia data; (b) issuing a search request for information
