Peer to peer contact information search method and system}

The present invention relates to a method and system for retrieving personal information by a P2P method. More specifically, when a request for retrieval of personal information is requested from a user's personal communication system, not only the contact persons stored in the user's personal communication system, The present invention relates to a personal information retrieval method and system using a P2P method that hierarchically searches even contact persons stored in a personal communication system of a user and extracts a search target.

In general, searching for a contact in a personal communication system such as a telephone, an e-mail, or an internet messenger can be performed only by searching for an object entered by the user in the personal communication system.

However, if the user wants to search for a contact that is not stored in the user's personal communication system, he had to contact the acquaintance of the user's acquaintances who knew the contact.

However, this method is not efficient in terms of time and cost, and even if the user does not know the contact information that the user wants to search, there is a problem in that the contact cannot be searched.

In order to solve the above-mentioned problems, an object of the present invention is to hierarchically search for personal information search between personal communication systems using personal information stored in a personal communication system, whereby contact information not stored in a user's personal communication system is stored. It is to automatically retrieve the personal information of the subject.

Another object of the present invention is to retrieve the personal information of the personal communication system in a P2P manner without invading the privacy of the individual.

FIG. 2 is a diagram illustrating a personal information retrieval system using a P2P method of searching for human information using hierarchical human information described with reference to FIG. 1.

As illustrated, the personal information retrieval system according to the present invention includes a personal communication system 20 including an input / output device 21, a contact DB 22, and a transceiving device 23, and a privacy rule editing unit 11. , Privacy rule base unit 12, privacy rule violation checking unit 13, search result creation unit 14, search expression creation unit 15, DB search unit 16, search expression receiving unit 17, and search And a contact retrieving device 10 having a result receiving unit 18. Here, the input / output device 21, the contact DB 22, and the transmission / reception device 23 of the personal communication system 20 are components that perform basic functions possessed by the existing personal communication system 20. A contact retrieval device 10 is provided to interoperate with the personal communication system 20 to retrieve personal information in accordance with the present invention. In addition, the contact search apparatus 10 may be provided inside the personal communication system 20 so that a separate device is not mounted on the personal communication system 20.

The search expression creation unit 15 processes the user inputting the necessary information for the search using the input / output device 21. When the search expression is input by the user, the search expression creating unit 15 contacts the DB 22 through the DB search unit 16. After searching to determine whether there is a search target in the primary contact, and if a target satisfying the search expression is extracted from the primary contact, the extracted information of the search target is transmitted to the input / output device 21 and displayed to the user. However, if there is no target satisfying the search expression among the primary contact targets, the transmission rule suitable for the privacy rule is determined through the privacy rule violation checking unit 13, and the search expression is transmitted through the transceiver 23.

The DB search unit 16 searches the contact DB 22 using a search expression input from a user or a search expression input from another user, and transmits the result to the search result creation unit 14.

When the search expression receiving unit 17 receives the search expression requested from the human information retrieval system of another user from the transmission / reception device 23, first determines whether to participate in the search through the privacy rule violation checking unit 13, and the search is performed. The DB search unit 16 is instructed to search the contact DB 22 only for the allowed search expressions.

The search result receiving unit 18 receives a result of a search request from a user's primary contact target stored in the contact DB 22, and transmits the result of the search request to the search result creating unit 14 through the input / output device 21. It is displayed to the user or transmitted to the personal information retrieval system of the original search request user through the transmission / reception device 23.

The privacy rule editing unit 11 provides a function for a user to edit a privacy rule necessary for searching for personal information through the input / output device 21. The edited privacy rule is stored in the privacy rule base unit 12. The privacy rule violation checking unit 13 refers to the privacy rule base unit 12 to determine whether the privacy rule of the search expression is violated.

The search result creation unit 14 creates a search result based on the information received from the DB search unit 16, the privacy rule violation checking unit 13, and the transceiver 23, and through the input / output device 21. It is displayed to the user or transmitted to the personal information retrieval system of the original search request user through the transmission / reception device 23.

FIG. 3 is a flowchart of a method of searching for human information by the configuration of FIG. 2 using hierarchical human information described with reference to FIG. 1.

First, the user inputs a search expression into his personal information retrieval system 4 (S2). The search expression may be the name of the personal information to be searched for, or may be a job, a school of origin, or an address. The search expression preferably includes a maximum degree of separation that restricts the scope of the search and a search ID for distinguishing the search expression. In FIG. 3, the maximum search order is set to 3 so that a search can be performed from the contact information stored in the personal information retrieval system 7 of the third contact person to the user, that is, to the fourth contact person.

When the search expression is input, the user's personal information retrieval system 4 transmits the search expression to the personal information retrieval system 5 of the primary contact person held by the user (S4). The transmission form of the search expression may be in the form of a short message (SMS) when the personal communication system is a mobile phone, or may separately implement a language for the search expression.

In response to the search expression (S6), the personal information retrieval system 5 of the primary contact object searches for a contact object owned by the user, that is, a user satisfying the search expression among the secondary contact objects (S8). .

At this time, if the search object is extracted (S10), it is not meaningful to continue the search by increasing the order, so the personal information search system 5 of the primary contact object creates a search result (S12) and the user's personal information search system ( 4), the process is terminated (S14).

However, if the search object is not extracted, the personal information retrieval system 5 of the primary contact object transmits a search expression to the human information retrieval system 6 of the secondary contact object that it holds (S16).

The human information retrieval system 6 of the second contact person who has received the search expression (S18) detects whether there is an object that satisfies the search expression among the third contact person, that is, the contact person, that is, the user. .

At this time, if the search object is extracted (S22), it is not meaningful to continue the search by increasing the order, so the human information search system 6 of the secondary contact object creates a search result (S24) and the personal information of the primary contact object. By transmitting to the retrieval system 5 (S26), the retrieval result is transmitted to the personal information retrieval system 4 of the user through the personal information retrieval system 5 of the primary contact object, and the process ends.

However, if the search object is not extracted, the human information retrieval system 6 of the secondary contact object transmits a search expression to the human information retrieval system 7 of the third contact object held by the secondary contact object (S28).

In response to the search expression (S30), the personal information retrieval system 7 of the third contact person searches for the contact person, that is, the user, that meets the search expression among the fourth contact objects (S32). .

At this time, if the search object is extracted (S34), the third person contact information search system (7) creates a search result (S36) and transmits to the second person contact information information system (S38) (S38) 2 The search result is transmitted to the user's personal information search system 4 through the personal information search system 6 of the primary contact object and the personal information search system 5 of the primary contact object, and the process is terminated.

On the other hand, even if the search object is not extracted, the personal information retrieval system 7 of the 3rd contact object produces a search result (S40). This is because the user initially limited the range of the search target by setting the maximum search order included in the search expression to 3, and the search result is notified even if the search target is not extracted.

The user's personal information retrieval system 4 then receives the final search result (S42) and displays it to the user (S44).

The final search result displayed on the user's personal information retrieval system 4 includes information about the personal information the user wants to search for, and lists the contact persons whose extracted personal information is included in the searched path in the search order. It is preferable that it is displayed. Accordingly, the user can select and save an optimal path among the paths, and use it again when rescanning. In addition, even when the extraction of human information fails, it is desirable to provide information on the search path so that the user can refer to it later when searching again.

In order for the retrieval process as described above to be successful, it is preferable that all the personal information retrieval systems have the same standard process. There is no need to be aware of the situation, and it is advisable that the primary, secondary, and tertiary liaisons set up their own information retrieval system in their personal information retrieval system so that the system operates automatically. Do.

Hereinafter, each process will be described in detail with respect to the user information retrieval system of FIG. 3 and the information retrieval system for the primary, secondary, and tertiary contact.

4 is a flowchart of a human information retrieval process of a human information retrieval system of a user who wants to retrieve human information according to the present invention.

When the user inputs a search expression to search for personal information (S46), the search expression creation unit 15 stores the contact object held by the user's personal information search system through the DB search unit 16, that is, the contact DB 22. A search is made to see if there is an object that satisfies the search expression among the first contact subjects (S48).

Accordingly, when a target that satisfies the search expression is extracted from the primary contact targets of the user's personal information search system (S50), the DB search unit 16 delivers the extracted search target information to the search result creation unit 14. The search result creation unit 14 creates a search result using the extracted search target information, displays the search result on the input / output device 21, and ends the search process (S58).

However, if the object that satisfies the search expression is not extracted from the primary contact object, the search expression creation unit 15 requests the search to the personal information search system of the primary contact object in a P2P manner, through the transceiver 23. The search expression will be sent.

To this end, first, the search expression generator 15 receives the maximum search order from the user through the input / output device 21 (S52). The maximum search order determines the maximum number of search targets. The maximum search order has an advantage of searching more objects as the order is higher, but the search time takes a lot, so the user must select the appropriate order.

When the maximum search order is input, the search expression creation unit 15 transmits the search expression entered by the user, the maximum search order, and the search ID to the personal information search system for the primary contact through the transceiver 23. .

The search ID is generated by the user's search expression creation unit 15 by itself. The search ID is generated when the user searches for personal information in a personal information search system other than his personal information search system, and the format is {user ID, search date, serial number} of the personal information retrieval system, where the ID of the user personal information retrieval system refers to a number that can identify the system, such as the telephone number of a mobile phone, and the retrieval date refers to the date that is retrieved. The number indicates the number of times personal information has been retrieved by another personal information retrieval system. In this case, the serial number indicates the number of times that the user's personal information retrieval system requests the personal information retrieval from another personal information retrieval system, so that the user can check how many personal information requests are made to the other human retrieval system. However, from the standpoint of the human information retrieval system of another contact person, it is meaningless information.

Then, when a search result is received from the personal information search system of the primary contact target (S56), the transceiver 23 receiving the received information transmits the corresponding information to the search result creation unit 14, and the search result creation unit 14. The search result is created using the corresponding information, displayed on the input / output device 21, and the search process is terminated (S58).

5 is a flowchart of a human information retrieval process performed in a human information retrieval system of an Nth contact person who receives a retrieval request of human information from a user's human information retrieval system.

The search expression receiving unit 17 of the N-person contact information search system that receives the search expression, the maximum search order, and the search ID together with the search request through the transceiver 23 (S60), once the privacy of the information is stored. The rule violation check unit 13 determines whether to reject the search request (S62). This is determined by conditions established by Nth Contact to prevent invasion of privacy. That is, the Nth contact object may not participate in the entire search requested or may selectively respond according to the received search expression. For example, if a received search ID is a duplicate of a previous search, you can set it to reject the search so as not to repeat the same search, accepting search requests only from users who are the primary contact for you, You can also specifically specify who will accept search requests, such as colleagues or school alumni.

In case of rejecting the requested search, the search result creating unit 14 creates a search rejection message and transmits it to the personal information search system that has requested the search by the transmitting and receiving device 23 and terminates its process ( S64), when accepting the requested search, the search expression receiving unit 17 first decreases the maximum search order by one order (S66), and then stores its 1 stored in the contact DB 22 through the DB search unit 16. Search whether there is an object that satisfies the search expression among the subjects of car contact (S68).

In this case, the reason for reducing the maximum search order received by the N-person contact information search system is that the N-contact person information search system is configured for the maximum search order input by the user who first requested the personal information search. This is because there will be fewer contacts to search after.

When the N-contact personal information search system extracts an object that satisfies the search expression from its primary contact object (S70), the search result generator 14 creates a search result and requests the search for personal information. Transfer to the search system and terminates its process (S72).

However, since the search object is not extracted and it is determined whether the maximum search order reduced by one order is 0 in the above-described S66 process, if the search order reduced by one order from the received maximum search order is 0, the search need not be performed anymore. The search result is written and transmitted to the personal information search system that has requested the search, and the process is terminated (S72).

On the other hand, the personal information search system of the N-th contact object is received by determining whether the object that satisfies the search expression is not among the primary contact objects, and whether the maximum search order reduced by one order in step S66 is zero. If the search order reduced by one order at the maximum search order is not 0, the search expression received at step S60 described above, the search order reduced by one order at step S66 described above, and the search ID are the individuals of the primary contact. It transmits to a communication system (S74).

Then, when the N-person contact information search system receives the search result from the personal information search system of its primary contact object (S78), it transmits it to the personal information search system that has requested the search and sends its own process. It ends (S80).

Although the above-described embodiment of the present invention has been described with reference to some mobile phones, it can be applied to any number by utilizing friend registration information of a general landline telephone or an e-mail address book or an internet messenger.

As described above, the present invention provides a method of searching for personal information between human information retrieval systems in a P2P manner, thereby using hierarchical relationships using contacts with new friends for protecting new privacy and personal information through setting search conditions. The search is effective.
