Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a participant authentication type information exchange system and method for exchanging information and materials using an IP network and a semantic information network, and an information communication terminal used in the system.
[0002]
[Prior art]
Conventionally, a centralized server is required for user authentication of the IP network and the semantic information network (for example, see Patent Document 1).
This patent document 1 relates to an “authentication and authorization method in an open distributed network”, and realizes load distribution and versatility by separating a user, a verifier, and an authority from a distributed type. I have. A verifier requests the user to present necessary information and issues profile information to the user. An authorizer requests presentation of the profile information, confirms the content, and determines whether the resource can be used. However, since the verifier has an authentication server and performs centralized management in one community, it has a centralized management unit.
In addition, when connecting to an IP network, user authentication is required, but when setting a filter, authentication is not required, so that abuse may occur. Also, even if there is an authentication system, there is no mechanism for checking once connected to the IP network.

[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an embodiment of a participant authentication type information exchange system and method according to claims 1 and 3 of the present invention. In this embodiment, a user 1 who is a new participant is initially set up. Is requested, and participants 6 and 11 authenticate. This information exchange system makes it possible to acquire information in accordance with a semantic information network 16, a 1P communication network 17, and a 1P communication network 17, which transfer a packet (herein called an event) having semantic information added to a header based on the semantic information. It includes filters 21, 22, 23, and information communication terminals and mobile information communication terminals 2, 7, 12 capable of setting these filters.
[0014]
The information communication terminal and the mobile information communication terminals 2, 7, and 12 are inserted in the 1P network 17 and the semantic information network 16, and these are the information communication terminals 3.8 and 13 and the mobile phone of the mobile communication terminal. 4, 9, 14 and PDAs 5, 10, 15. The filter means that the event receiver registers the semantic information of the data desired to be received in the semantic information network 16 as metadata.
In the information exchange system using the semantic information network 16, if the attribute information does not match the set attribute, the filter does not fire and the attribute information itself is not transmitted, so that security is maintained.
[0015]
In the participant authentication type information exchange system shown in FIG. 1, the information communication terminal and the mobile communication terminal 2 of the user 1 include the position, affiliation, charge, age and gender (the attribute type is arbitrary, but in this example, The user 1 has an attribute of a self-attribute blue report DB 31 and an attribute of another person's attribute information DB 32, and the user 1 has an information communication terminal 2 to make a request for participation in the information exchange system. Alternatively, the personal attribute is transmitted from the personal attribute information DB 31 to the semantic information network 16 as an event by using a mobile phone 4 or a PDA (Personal Digital Assistant) 5 of the mobile communication terminal.
[0016]
The filters 22 and 23 of the participants 6 and 11 participating in the information exchange system of the semantic information network 16 fire in response to this event, and the information communication terminals and the mobile communication terminals 7 and 12 of the participants 6 and 11 are activated. Receives the attribute of the self-attribute information DB 31 and authenticates the user 1 based on the received self-attribute information DB 31 and the attributes of the other-person attribute information DBs 34 and 36 in the information communication terminal and the mobile communication terminals 7 and 12. Based on the result of the authentication, whether the setting of the filter is possible is determined, and the determination is returned to the semantic information network as a reply. That is, the received own attribute information DB 31 of the user 1 is compared with the attributes of the other person attribute information DBs 34 and 36 in the information communication terminals of the participants 6 and 11 and the mobile communication terminals 7 and 12. The user 1 returns to the semantic information network 16 an acknowledgment of "permitted" that allows the user 1 to register his or her own attribute as the filter 21. If the attribute is different, a "no" of the filter registration is returned.
[0017]
When the user 1 receives the approval of the setting “OK” of the filter 21 from the participants 6 and 11 at the information communication terminal 3, the mobile phone 4, the PDA 5, or the like, the user 1 transmits the semantic information such as the own attribute and the material to the semantic information network 16. The filter 21 is set. If the setting request for the filter 21 received by the user 1 is “No”, the registration setting of the filter 21 becomes impossible and the filter cannot be set.
[0018]
As described above, in the system of FIG. 1, the communication terminal 2 of the user 1 has the attribute information DB of the job attribute or the qualification and the attribute information DB of the other person attribute DB. The attribute of the participant is sent as an event, and a request is made to the communication terminals of a plurality of participants 6 and 11 to determine whether or not to set a filter. The communication terminal of each participant transmits the received attribute information and the communication terminal of the participant. It collates with a certain other person attribute information DB, and if the attribute is the same, it replies with an authentication of “OK”, and if it is different, it replies with an authentication of “NO”. If the received authentication is "OK", the user can register and set the filter 21 in the semantic information network.
Therefore, in this system, since the user is authenticated by the user receiving the determination of the filter setting from the participant participating in the information exchange system, centralized management of the authentication server and the attribute information is not required. .
[0019]
FIG. 2 shows a processing flow in the participant authentication type information exchange system and method according to the second and fourth aspects of the present invention.
(1) The user 1 requests the semantic information network 16 to participate in the system.
{Circle around (2)} The user 1 sends his / her attribute from the own attribute information DB 31 to the semantic information network 16 as an event for this request, and a plurality of participants 6 using the information exchange system in the semantic information network 16. 11 is requested to determine whether to permit registration of filter settings.
{Circle around (3)} The participants 6 and 11 receive the own attribute of the user 1 and collate the received own attribute with the other person attribute information DB 34 in the information communication terminal or the mobile communication terminal 7 of the participant 6, If they are the same, authentication "OK" is returned. If they are different, authentication "NO" is returned. In the case of "OK" authentication, the participants 6 and 11 return their attributes from the own attribute information DB 33 as replies.
{Circle around (4)} If the determination of the filter setting received from all the participants 6 and 11 is “OK”, the user 1 sets the semantic information such as the own attribute and the material as the filter 21 in the semantic information network 16. Also,
[0020]
(5) The user 1 collates the received attribute information of the participants 6 and 11 with the other person attribute information DB 32, determines whether or not authentication is possible, and returns the result to the participants 6 and 11 as a reply.
{Circle around (6)} The participants 6, 11 delete the filters 22, 23 of the participants 6, 11 by using the filter deletion function when the received authentication determination is “No”.
According to the participant authentication type information exchange system, since the user terminal authenticates the participant who is participating in the information exchange system, a false participant can be found.
[0021]
FIG. 3 shows the information communication terminals of the user 1 or the participants 6, 11, 18 and the mobile communication terminals 2, 7, 12, 27 used in the participant authentication type information exchange system shown in FIGS. FIG. 3 is a diagram showing a configuration and attributes built in each terminal.
The information communication terminal and the mobile communication terminal 2 of the user 1 have built-in attribute DBs of a self-attribute information DB 31 and another person's attribute information DB 32 as attributes. Affiliation: manufacturing; charge: material; age: 36; gender: male; location: Shinjuku and other attribute information DBs are built in, and the others attribute information DB 32 participates in the community in the semantic information network 16. Participants 6,11's other person attribute information DBs 34, 36, 39 are registered. For example, as the ID and data of the participant 6, title: employee; affiliation: sales; charge: corporation; age: 28; gender: female; Location: Attribute information DB such as Nakano is built in.
[0022]
The information communication terminal and the mobile communication terminal 7 of the participant 6 have a built-in own attribute information DB 33 and another person attribute information DB 34 as attribute DBs. Affiliation: sales; charge: corporation; age: 28; gender: female; location: Nakano and other attribute information DBs are built-in. Attribute information is registered. For example, as an ID and data of the user 1, there is an attribute information DB such as title: chief; affiliation: manufacturing; charge: material; age: 36; gender: male; location: Shinjuku. I have.
[0023]
The information communication terminals and the mobile communication terminals 12 of the other participants 11 also have their own attribute information DB 35 and the attribute DB of the other person attribute information DB 36.
Also, the information communication terminal of the user 1 or the participants 6, 11 and the mobile communication terminals 3, 7, 12 have an attribute matching function for matching the attributes of the self attribute information DB and the attributes of the other person attribute information DB (that is, the user). Or an authentication function for authenticating a participant), a function of requesting participation in a community in the semantic information network 16, a filter setting function, and a filter deleting function (claim 3).
In order to realize a participant authentication type information exchange system with the mobile communication terminals of the mobile phones 4, 9, 14 and the PDAs 5, 10, 15, the PDAs 5, 10, 15 are more advantageous because they have larger memory capacity and CPU capacity. It is easy to realize.
[0024]
[Example 1]
A description will be given of an embodiment of a participant authentication type information exchange system in which a new participant 19 joins a community in the semantic information network 16 and obtains the authentication of the participation determination of the participant and sets a filter.
FIG. 4 shows a step of transmitting the self-attribute of the self-attribute information DB 37 of the new participant 19 in order to obtain the authentication of the participant in the present system.
When the new participant 19 makes a request to participate in the community in the semantic information network 16, the participation request function in the communication terminal 29 of the new participant 19 The attribute is sent to the semantic information network 16 as an event.
The self-attribute information DB 37 includes ID and data such as post: chief inspector; affiliation: manufacturing; charge: material; age: 36; gender: male;
The filters 22, 23, and 24 of the participants 6, 11, and 18 participating in the system fire in response to this event, and the communication terminals 7, 12, and 27 of the participants 6, 11, and 18 enter the new participant 19. Receives its own attribute.
[0025]
FIG. 5 shows steps in the present system in which the participants 6, 11, and 18 who have already participated in the present system authenticate the new participant 19.
The communication terminals 7, 12, and 27 of the participants 6, 11, and 18 receive the self-attribute information transmitted by the new participant 19, and the attribute matching function compares the attribute information with the other-person attribute information DBs 34, 36, and 39. Is determined, and if “OK”, the own attribute information DBs 33, 35, and 40 of the participants 6, 11, and 18 are added to this and transmitted as a reply to the new participant 19 to the semantic information network 16. I do. If the data returns empty, the authentication fails.
[0026]
FIG. 6 shows a step in which the new participant 19 registers the filter as a result of the authentication of the participants 6, 11, 18 for the filter setting in the present system.
The new participant 19 obtains authentication of registration as a filter of the self-attribute information DB 37 from all the participants 6, 11, and 18, so that the filter setting in the information communication terminal and the mobile terminal 29 of the new participant 19 is performed. Using the function, the semantic information such as the attribute and the material of the self-attribute information DB 37 is registered as the filter 25 in the semantic information network 16 and set.
In the filter 25, filter information that is commonly handled by the community, such as which community is participating and which application is used by the participants, are also set.
[0027]
Although not shown in the figure, in the present system, the communication terminal 29 of the new participant 19 further receives the attribute information of the participants 6, 11, and 18, and receives the attribute received by the attribute matching function in the terminal. And the other person's attribute information DB 41 to determine whether or not authentication is possible, and return the result of the determination to the participants 6 and 11 as a reply.
The participants 6, 11, 18 delete the filters 22, 23, 24 of the participants 6, 11 using the filter deletion function in each terminal if the received authentication determination is "No".
[0028]
According to the information exchange system, the new participant 19 or the community participant 6, 11, or 18 can set the attribute information of the new participant's own attribute information DB 37 and the other person's attribute information DB 41, or all the participants 6, 11, 18 Unless the attribute information in the own attribute information DBs 33, 35, 40 and the other person attribute information DBs 34, 36, 39 is falsified, it is impossible for an unauthorized participant to intercept the attribute information and information other than the attribute from outside. .
[0029]
[Example 2]
FIG. 7 is a diagram showing that the participant authentication type information exchange system shown in FIGS. 4 to 6 of the present invention can discover a new participant who obtains illegal information.
A description will be given of a case where the impersonated new participant 20 attempts to illegally obtain information of the community participant and falsely sets the post and chief of the ID and data in the self-attribute information DB 38 to the filter 26 as the post: chief president. .
The spoofed new participant 20 gives the false information of the self-attribute information DB 38 to the semantic information network, and requests the participants 6, 11 and 18 participating in the present system to judge whether or not to set the filter.
[0030]
The participants 6, 11, and 18 requested to determine whether or not to set the filter have the received information of the self-attribute information DB 38 of the new spoofed participant 20 stored in their own information communication terminals and mobile terminals 7 and 12. This is a system in which it is found that the ID and data do not match the actual status of the post: chief inspector as a result of the collation by using the other person attribute information DBs 34, 36, and 39, and as a result of the collation. Reference numeral 18 transmits an authentication notification of the filter registration “NO” to the false new participant 20 as a reply.
The impostor new participant 20 receives the result at the information communication terminal and the mobile terminal, finds that illegal information has been obtained, and cannot register the filter 26 in the semantic information network 16.
[0031]
[Example 3]
FIG. 8 shows that in the participant authentication type information exchange system shown in FIGS. 4 to 6 of the present invention, it is possible to discover the participant 28 who participates by misrepresenting the self-attribute information DB 42 in the participant. FIG.
A case where there is a participant 28 who participates in the information exchange system by misrepresenting the self-attribute information DB 42 by some means will be described.
The spoofing participant 28 has registered the ID and the data of the self-attribute information DB 42 as the person who authenticates the post and the manager as the post and the manager.
[0032]
The self-attribute information DB 42 is capable of participating in the present system since all of the participants including the other participants' attribute information DBs 36 and 39 are misrepresented, including the participating participants 11 and 18. When the false self attribute of the DB 42 is added and registered as a filter, the event is fired for the new participant 19, and the information communication terminal of the new participant 19 and the other person attribute information DB 41 in the mobile terminal are still at the time of participation, so that the false name is impersonated. In this case, the impersonation ID of the post: manager is found even though the post is an employee, and it is found that the attribute DB is different.
As a reaction, the setting of the filter 22 of the false participant 28 is deleted, and it is impossible to participate.
[0033]
Unless the other-person attribute information DB of all the participants is falsified, it is possible to find a false participant.
As described above, when there is a difference between the attribute DB of the user and the participant's own attribute information DB and the attribute DB of the other person's attribute information DB, it is excluded from the community of the information exchange system, and the filter setting in the semantic information network 16 is performed. It is possible not to permit the setting and to change the set filter. Basically, the filter setting is not permitted unless permitted by the approval performed before the initial filter registration.
[0034]
However, in the case of P2P, if the information of other participants' attributes has been tampered with, it is discovered that there is a tampered participant when the unaltered participant joins or after a certain period of time. S. It is possible to change the set filter by a specific method.
In the information exchange system, it is possible to change the attribute information or data information of a large number of participants 6, 11, 18 and the like participating in the community. For information, it is possible for the director, which is a higher-level attribute, to give opinions and instructions to the information and change the information such as attributes. Also, each attribute of the participant has a point, and the attribute to be set by calculation according to the height of the evaluation point so that the opinion etc. of the participant who has a relatively strong voice among the participants is given priority. You can also decide.
[0035]
The means and procedures of the participant authentication type information exchange system and method of the present invention have been described above. However, these procedures and means can be executed or realized by a computer, and the present invention executes these procedures or means. Alternatively, a computer program for realizing the program and a recording medium on which the program is recorded are also included in the scope of the present invention.
[0036]
【The invention's effect】
-A user or a plurality of participants who participate in the information exchange system determines whether or not to register and set attribute information and semantic information such as materials in a semantic information network as a filter, and to determine whether or not attribute information and attribute information are to be set. It does not require a management unit that centrally manages semantic information such as materials.
-Unless information such as attributes of all participants is falsified, it is impossible to see information such as attribute information on the semantic information network.
Even if the impersonation registration succeeds at the time of registering the filter, it is possible to exclude a user who has been improperly impersonated and registered from the community when a user having correct attribute data participates.
The user or the participant has the attributes of the self-attribute information DB and the other-person attribute information DB, and if there is a difference between the attribute data, the permission of the participant to be performed before the initial filter registration is approved. Otherwise, it cannot be registered and set in the filter.
-The participant authentication type information exchange system can change information such as attributes of many participants participating in the community.
-The user can receive the opinion and instruction of the participant who is the higher attribute and change the information such as the attribute.
-The user can determine an attribute to be set at a point having a high evaluation level by giving priority to the opinion of a participant having a voice in the exchange system participating in the community.
