     TECHNICAL FIELD 
     The present invention relates to a social network service apparatus and a service method thereof, and in particular to a social network service apparatus and a service method thereof which has features in that a friend group is made through a function (open key) of helping make a friend relationship in such a way that a user designates one acquaintance at a time or make a plurality of friend relationships at a time, so a 1 to 1 (individual) friend relationship and an authorization is basically set up between the user and the acquaintances, and a secret is set between the user and each friend so that they can know, in a permitted range, a relationship of them, a communication content between them and a sharing situation of data, and the data that the user uploaded in a push way based on the set friend relationship are shared 1 to 1 between the connected friends, and the information are jointly built between the acquaintances based on the set authorization and the shared data, and the information are re-shared, by means of which a full range of social network service can be achieved. 
     BACKGROUND ART 
     In the modern informative society, a computer and an Internet have become a necessary tool in terms of communications as a medium of transferring various information. In this context, a new relationship among people comes to form about the network. 
     A SND (Social Network Service) or a SCS (Social Community Service) is referred to a service that forms and maintains a community including specific persons of which each user has a specific relationship based on the Internet environment. 
     The SNS at the first stage of introduction begun in a form of chatting-based community which was performed based on a PC (Personal Computer) communication, and afterward, the PC environment advanced from the PC communication to the WWW (World Wide Web) environment, which provoked a change in the social network service environment, and with the development in the field of the blog, the social network service has started in full scale. 
     In recent years, the wired and wireless social network services have been launched, which are a wired and wireless cooperating social network configured to be used on a mobile communication terminal like a cellular phone, a smart phone, etc. and a wired internet in a convenient way. Since mobility is made possible by a mobile communication terminal, a user can advantageously record his own thought and feeling wherever and whenever or can invite others. The key feature of the above service lies in easily inviting as a friend all the acquaintances registered in an address list and a messenger of a mobile communication terminal and in sending a user&#39;s text through a text message function and a messenger even to acquaintances who are not registered in a corresponding service, so it is possible to integrally control all personal connections of the users. 
     In the typical social network service, the data the user uploaded can be viewed only when the friends that the user designated visit the user&#39;s blog or homepage, so the friends who don&#39;t visit the user&#39;s blog or homepage cannot know the data that the users uploaded. 
     In addition, the typical social network service is operated in such a way that the generator who generates contents and the customer who consumes the contents are separated, so it is hard to create a shared and common value that the social network targets to obtain. 
     The typical social network service is being provided in an open format like the blog or cafe that the user himself operates, a person that the user does not want can visit or a content and a communication that the user does not want may be generated, so the user may have a problem in its management and operation, which is not intended by the user due to the above mentioned problem, so a personal privacy protection is not guaranteed. 
     In addition, the typical social network service has another problem in that when the data are transmitted and shared in real time through the mobile communication terminals of the friends registered in the address list and the messenger in cooperation with the mobile communication terminal, the sharing is allowed depending on the text data or the low capacity due to the limits in the data transmission speed and the data storage capacity.

       FIG. 1  is a view illustrating a concept of a social network service system according to an embodiment of the present invention. Referring to the drawing, a user terminal  10  of a user and acquaintance terminals  20  and  30  of acquaintances of the user may be connected to a social network service apparatus  200  though a network  40 . 
     Here, the user terminal  10  is a subscriber of a social network service according to an embodiment of the present invention and is a terminal which is connected to the social network service apparatus  200  through the network  40  for thereby uploading data on a cyber space provided by the social network service apparatus  200  for the sake of sharing the data. 
     The acquaintance terminals  20  and  30  are the terminals of the acquaintances of the social network formed on the internet through the social network service according to an embodiment of the present invention, which acquaintance terminals can be connected to the social network service apparatus  200  through the network  40  and can display the data authorized to the user himself among the data uploaded on the cyber space provided to the user or can output by downloading the same. Here, the terminal for the upload of the data with respect to the cyber space and the terminal of the sharer with respect to the same are sorted into a user terminal  10  and acquaintance terminals  20  and  30 . 
     The user terminal  10  and the acquaintance terminals  20  and  30  include a personal computer (PC), a notebook computer, a personal digital assistant (PDA), a portable multimedia layer (PMP), a play station portable (PSP), a mobile communication terminal, a smart phone, etc. 
     In addition, the network  40  includes an internet network as well as a mobile communication network and a wireless communication network such as a code division multiple access (CDMA), a wideband code division multiple access (WCDMA), a global system for mobile (GSM), a long term evolution (LTE), and an evolved packet core (EPC). 
     In addition, the social network service apparatus  200  supports a social network service to the user terminal  10  and the acquaintance terminals  20  and  30  through the network  40  for thereby expanding a 1:1 relationship between the user and each acquaintance, so it is possible to form a truly meaningful sharing relationship with the user. The construction and function of the social network service apparatus  200  will be described with reference  FIG. 2 . 
       FIG. 2  is a schematic view illustrating a construction of a social network service apparatus according to an embodiment of the present invention. Referring to  FIG. 2 , the social network service apparatus  200  according to an embodiment of the present invention comprises a cyber space provision unit  210 , a friend information storage unit  220 , a friend designation unit  230 , a data sharing information transmission unit  240  a data storage unit  250 , an authorization assignment unit  260  and a message transmission unit  270 . Here, the social network service apparatus  200 , as described above, may be used as a server supporting a formation of a social network between the user terminal  10  and the acquaintance terminals  20  and  30 . At this time, the social network service apparatus  100  of  FIG. 2  is shown like it is formed of one server; however each server may be formed of a server performing an independent function. With the interoperations of the servers, it can support a formation of a social network between the user terminal  10  and the acquaintance terminals  20  and  30  according to an embodiment of the present invention. 
     The cyber space provision unit  210  provides a cyber space in which a secret can be exclusively maintained on a network including at least one of a Web page and a Wap page by subscriber. In other words, the cyber space provision unit  210  stores the source of a Web page and provides a cyber space which is designated to a corresponding user terminal  10  and in which a secret can be exclusively kept when the user terminal  10  is connected through a Web browser or a dedicated program. For example, the cyber space provision unit  210  can provide a subscriber, called Hong, Gil-dong, with a Web page type cyber space as shown in  FIG. 3 . Through the cyber space, the subscriber (Hong, Gil-dong) can upload his own document or a file or can link to the address where stores a specific information on the network. At this time, the data which can be uploaded into the cyber space may be various contents such as a motion picture, an image, a voice file, a document, etc. 
     In addition, the subscriber (Hong, Gil-dong) can register the acquaintances formed on the network  40  as the friends in the cyber space as shown in  FIG. 4 . At this time, the friend information storage unit  220  can sort by the subscriber the information on the friends that each subscriber has registered in the cyber space and can store them as the database. For example, the friend information storage unit  220  can store by sorting the names, e-mail addresses, birthdays and sexes of the registered friends, and an identifier can be inserted in the sorted information for the purpose of identifying a corresponding information. The friend information sorted and stored by the friend information storage unit  220  is not limited to the disclosed contents, and various information can be sorted and stored. In addition, the friend information storage unit  220  has a friend management function of helping register a friend through a search among the subscribers registered to the social network service or registering a friend through an invitation when the acquaintance in real life is subscribed in the social network service or introducing each other the information on the previously registered friends or adding or deleting the friends. 
     The friend designation unit  230  is configured to designate at least one friend among the friends stored in the friend information storage unit  220  based on the data uploaded and shared in the cyber space by each subscriber. For example, as shown in  FIG. 4 , the friend that the subscriber (Hong, Gil-dog) has registered in the cyber space is a friend A, a friend B and a friend C and uploads a motion image data and a document data in his own cyber space, the friend A can be designated to the motion image data, and the friend B and the friend C can be designated to the document data. 
     The data sharing information transmission unit  240  judges the connection state of the user and the connection state of the friend designated by the friend designation unit  230 . At this time, the data sharing information transmission unit  240  transmits in a push method the cyber space of the user to the user terminal  10  when it is judged that the user has connected and shares the same, so it becomes possible to amend or delete the data uploaded and shared by the user and to further upload and share the other data. In addition, the data sharing information transmission unit  240  transmits, in a push method at a certain cycle, the shared information of the data to which the sharing authorization is assigned as it is uploaded in the user&#39;s cyber space in the acquaintance terminals  20  and  30  of a corresponding friend when it is judged that the friend designated by the friend designated unit  230  has connected. For example, in case of the above mentioned subscriber (Hong, Gil-dong), the data sharing information transmission unit  240  transmits in a push method at a certain cycle the motion image data sharing information to the terminal of the friend A when it is judged that the friend A has connected for thereby allowing a connection to the sharing authorization-assigned motion image data. When it is judged that the friend B or the friend C has connected, the document is transmitted in a push method at a certain cycle to the terminal of the friend B or the friend C for thereby allowing a connection to the sharing authorization-assigned document data. 
     Here, the data sharing information transmission unit  240  is named because the data uploaded by the user is copied but is not transmitted to the terminal of the designated friend, and instead only the information such as the sharing authorization and read, amendment, deletion, addition and transfer, etc. of the uploaded data is transferred. In other words, in terms of the uploaded data it operates in such a way that only one data uploaded by the user is present in the data storage unit  230 . The friends with a sharing authorization with respect to one uploaded data can connect to the data registered in the data storage unit  230  with the sharing authorization, and the data can be shared. 
       FIG. 5  is a view for explaining an open key which is a method for forming multiple friend information at one time shown in  FIG. 4 . Generally speaking, in terms of the friend relationship of  FIG. 3 , the friends can be registered through the search among the subscribers subscribed in the social network service of the present invention or in case that the acquaintance of a real life is subscribed in the social network service, the friend can be registered through an invitation or can be separately registered through a procedure such as an introduction, an addition and a deletion of the information with respect to the previously registered friends; however as compared thereto, it can be applied when it needs to make at a time multiple friend relationships, for example, for the sake of a club, alumnus or business. In terms of the open key provision unit  280 , when a user needs to form multiple friend relationships at a time, the open key is assigned from the open key provision unit  280 , and it is provided in a cyber space which becomes a contact point with people who want to form a friend relationship such as a blog, a cafe, a shopping mall, a homepage, a social network service page, etc., and they click the open key, and the cyber space provision unit  210  provides a cyber space to them immediately, through which they can make friend relationships with the user. The friend ground with the friend relationship made with the open key is stored in the friend information storage unit  220  or may be sorted from the previously separately formed friends and may be separately stored. However, the other function portions such as other data sharing, etc. can be identically adapted. 
       FIG. 6  is a view for explaining an example for sharing a message in real time with a friend designated based on a cyber space of  FIG. 3 . As shown therein, the subscriber designates the friends displayed as being currently connected among his friends and communicates in real time on the messages with corresponding friends, and can communicates on the messages with the friends who are not connected. In this case, when a corresponding friend is connected with the social network service apparatus  200 , it is received on the friend&#39;s terminal and is displayed thereon. The real time message explained in the drawings of the present invention is not limited to only the transfer of the simple text characters, but it can be used for the attachments of files such as an image, a motion image, a file, etc. and for a transfer of map information at a time, so as compared to the typical method, various and abundant communications can be made. 
       FIG. 7  is a view for explaining an example for sharing a document with a friend designated based on the cyber space of  FIG. 3 . It shows an example in which a data that the acquaintances (friend A, friend B and friend C) that the subscriber (Hong, Gil-dong) has designated as friends upload, with the authorization of the date being assigned to the subscriber (Hong, Gil-dong). In other words, when the acquaintances who have designated the subscriber (Hong, Gil-dong) as their friends upload the data in their cyber spaces and designate the subscriber (Hong, Gil-dong) as a friend having a sharing authorization with respect to the data, and when the subscriber (Hong, Gil-dong) connects to the social network service apparatus  200 , the data assigned with the sharing authorization can be received on the terminal of the subscriber and can be displayed thereon. At this time, while the subscriber is being connected to the social network service apparatus  200 , the data information assigned with the sharing authorization among the data uploaded on the cyber space of each acquaintance can be continuously received at a constant cycle on the subscriber. As shown in  FIG. 7 , the thusly-received data sharing information can be displayed on the subscriber terminal in the form of a list, and when one of the displayed lists is selected, it can be implemented in such a way that the uploaded data corresponding to the selection can be displayed. 
     The data storage unit  250  stores the data uploaded in the cyber space provided by the subscriber in relation with the friends assigned with the sharing authorization by means of the subscriber and friend designation unit  230 . In case of the earlier described subscriber (Hong, Gil-dong), the uploaded motion image data is stored in relation with the designated friend A, and the document data is stored in relation with the friend B and the friend C assigned with the sharing authorization. At this time, the data storage unit  250  sorts the data uploaded in the cyber space provided by the subscriber to have a link information showing the contents having a motion image and an image, documents, schedule and storage position of other information and stores them. 
     The authorization assignment unit  260  can assign an authorization with respect to at least one among a read, addition, modification, deletion, transfer, etc. with respect to each friend designated by the friend designation unit  230 . For example, in case of the earlier described subscriber (Hong, Gil-dong), the authorization assignment unit  260  assigns only the read authorization to the friend A designated to the uploaded and shared motion image data, and assigns the read, addition and modification authorizations to the friend B who is designated with respect to the uploaded and shared document data, and assigns the read, addition, modification, deletion and transfer authorities to the friend C. In this case, the friend A can only read, namely, view the motion image data of the subscriber (Hong, Gil-dong) displayed on his own terminal when he is connected to the social network service apparatus  200 . The friend B can read, add and modify the document data of the subscriber (Hong, Gil-dong) displayed on his own terminal. The friend C can read, add and modify or can delete the document data uploaded by the subscriber (Hong, Gil-dong) or provide the sharing authorizations to other acquaintances of him and transfer them. 
       FIG. 8  is a view for explaining an example for managing a schedule with a friend designated based on the cyber space of  FIG. 3 . As shown therein, the subscriber uploads a data on a schedule management in his own cyber space, and designates a friend with respect to the uploaded schedule management data, and assigns an authorization such as an addition, deletion and modification, so the subscriber and the designated friend can share the schedule between them, and in particular the schedule of the drawings of the present invention contains the sharing of the time related information and text information, and further contains the attachments of the image, motion image, file, etc. for each schedule as well as the registration of the map information at a time, so as compared to a typical method, various and abundant communication are possible. In addition, the sharing can be individually possible for each schedule, so various individual relationships such as a friendship activity and business between acquaintances can be usefully applied. 
       FIG. 9  is a view illustrating for explaining an example for sharing a friend and an address designated based on a cyber space of  FIG. 3  and an address. As shown therein, the subscriber makes a common address information and an address group with respect to an information of a specific subject and registers the position information with respect to the information of the specific subject, and registers the position information of the internet in which the address group stores the related addresses and the related information and uploads them in the cyber space and designates the friends who will share the address group and provides the designated friends with the addition, modification, deletion and transfer authorizations with respect to the address group, the registered addresses and the position information of the internet. In this case, if the designated friend knows the addresses with more specific and expanded information as compared to the address information uploaded in the cyber space, a corresponding information can be added or deleted or can be transferred to other friends who need them, and the user as well as related friends can share more expanded information with respect to specific subjects. 
       FIG. 10  is a view for explaining an example for sharing the friends and materials designated based on the cyber space of  FIG. 3 . As shown therein, the subscriber can make a material group on a specific subject and can register the material related with the material group and can directly upload them in his own cyber space and can designate the friends who can share the uploaded material group and can assign the designated friends with modification, deletion, addition and transfer authorizations. In this case, the designated friend can modify and delete when the material information uploaded in the cyber space is wrong and can transfer a corresponding material to other acquaintances who know in details for thereby correcting or adding the wrong materials. With the modification, deletion, addition and transfer authorization of the above mentioned materials, it is possible to build high reliability information, and the related friends can share the more expanded material information. 
       FIG. 11  is a view for explaining an example for relaying the information with the aid of the social network service according to an embodiment of the present invention. The above information relay can be formed by the transfer authorization of the data. For example, the user A can designate the friend B with respect to the data uploaded in his own cyber space and assign the sharing authorization as well as assign a transfer authorization, and the friend B can designate the friend C with respect to the data shared by the user A and assign the sharing authorization as well as the transfer authorization. In this manner, the data uploaded in the cyber space by the user A can be continuously transferred to the others by the sharing and transfer authorizations, and can be modified or added. So, the adaptive information can be built depending on the era and circumference, thus enhancing the reliability of the information. The subscribers at each stage can share the information, so they can share higher quality information than the quality of the information that he can obtain for himself. In the drawings, it is shown like the final receiver D is the acquaintance of the user A during the continued transfer procedure; however the receiver D may not be the acquaintance of the user A, and the transfer procedure can be continuously performed. 
     When the user uploads the data in the cyber space of the user, and it is judged that the acquaintance designated as a friend of a corresponding data is not connected, the message transmission unit  270  can transfer a guide message, which guides a connection, to the terminal of a corresponding designated friend. For example, when the earlier mentioned subscriber (Hong, Gil-dong) uploads the document data in a cyber space, and it is judged that the friend B designated as a friend who is assigned with the sharing authorization of a corresponding document data is not connected, the message transmission unit  270  cooperates with the short message server (SMS) (not shown) and transmits to the terminal of the friend B a message guiding a connection to the social network service apparatus  200 . 
       FIG. 12  is a flow chart of a social network service method according to an embodiment of the present invention, while showing a social network service method based on the social network service apparatus  200  of  FIG. 2 . 
     Referring to  FIGS. 2 and 12 , the cyber space provision unit  210  provides a cyber space in which a secret is exclusively kept on the network containing at least one of a Web page and a Wap page by the subscriber (S 1010 ). In other words, the cyber space provision unit  210  can provide a cyber space which is designated in a corresponding user terminal  10  and can store the source of the Web page and in which a secret can be exclusively kept when the user terminal  10  connects through a Web browser or a dedicated program. 
     The friend information storage unit  220  sorts by the subscriber the information on the friends registered in the cyber space by the subscriber and stores in the database (S 1020 ). For example, as shown in  FIG. 3 , the friend information storage unit  220  can store the friend A, the friend B and the friend C as the fiends with respect to the subscriber (Hong, Gil-dong). 
     The friend designation unit  230  can designate one of the friends stored in the friend information storage unit  220  as a friend having a sharing authorization in response to the data uploaded in the cyber space by each subscriber (S 1030 ). For example, as shown in  FIG. 4 , when the friend registered in the cyber space by the subscriber (Hong, Gil-dong) uploads the motion image data and the document data in his own cyber space, the friend A is designated as a friend having a sharing authorization with respect to the motion image data, and the friend B and the friend C are designated as friends having a sharing authorization with respect to the document data. 
     The authorization assignment unit  260  can assign an authorization with respect to at least one among a read, addition, modification, deletion and transfer with respect to each friend designated by the friend designation unit  230  (S 1040 ). For example, in case of the earlier mentioned subscriber (Hong, Gil-dong), the authorization assignment unit  260  assigns only the read authorization to the friend A designated with respect to the uploaded motion image data, and assigns the read, addition and modification authorization to the friend B designated with respect to the uploaded document data, and assigns the read, addition, modification, deletion and transfer authorizations to the friend C. In this case, the friend A can read, namely, view only the motion image data uploaded by the subscriber (Hong, Gil-dong) displayed on his own terminal when he is connected to the social network service apparatus  200 , the motion image data providing a sharing authorization to the friend A, and the friend B can read, add and modify only the document data uploaded by the subscriber (Hong, Gil-dong) displayed on his own terminal and designating the friend B as having a sharing authorization, and the friend C can read, add and modify as well as delete the document data uploaded by the subscriber (Hong, Gil-dong) and designating the friend C as a friend having a sharing authorization and can transfer the same to his other acquaintances. 
     The data storage unit  250  stores the data uploaded in the cyber space provided by the subscriber along with the authorization assigned to each designated friend in relation with the friends designated as a friend having a sharing authorization by the subscriber and the friend designation unit  230  and the authorization information with respect to a read, modification, deletion, addition and transfer (S 1050 ). In case of the earlier mentioned subscriber (Hong, Gil-dong), it stores what the read authorization is assigned in relation with the friend A designated as a friend having a sharing authorization with respect to the uploaded motion image data, and it also stores along with the authorization assigned to each in relation with the friend B and the friend C designated as a friend having a sharing authorization with respect to the document data. At this time, the data storage unit  250  sorts the data uploaded in the cyber space provided by the subscriber as a link information representing the storage positions of the contents, document, schedule management and other information containing the motion images, the image, etc. 
     The data sharing information transmission unit  240  judges the connection state of the user and the connection state of the friend designated by the friend designation unit  230  (S 1060 ), and when the designated friend is connected (S 1070 ), the sharing authorization of the data uploaded by the user and the authorization information such as a read, modification, deletion, addition, transfer, etc. are pushed to the designated friend terminal at a certain period and are transmitted (S  1080 ). Here, the data uploaded by the user is copied and not transmitted to the terminal of the designated friend, but only the sharing authorization of the uploaded data and the information such as the read, modification, deletion, addition, transfer, etc, are transferred. In other words, in terms of the uploaded data, only one data uploaded by the user is present in the data storage unit  230 . The friends having a sharing authorization with respect to the uploaded data connect to the data registered in the data storage unit  230  through the sharing authorization, and it operates in the shared type. 
     If it is judged that the designated friend is not connected (S 1070 ), the message transmission part  270  can transmit a guide message to the terminal of a corresponding friend for the purpose of guiding the connection to the social network service apparatus  200  (S 1090 ). 
     All the constructional elements of the embodiments of the present invention have been described operating as they are engaged as one element; however the present invention is not limited to such embodiments. In other words, within the ranges of the objects of the present invention, at least two elements among the above mentioned constructional elements may be selectively engaged and operate. In addition, all constructional elements may be implemented in a form of an independent hardware as one element; however part or all of the above constructional elements may be selectively combined for thereby being implemented as one a computer program having a program module performing part or all of the functions combined from one or multiple hardware. In addition, the computer program is stored in the computer readable media such as a USB memory, a CD disk, a flash memory, etc., so it is read by the computer and is executed for thereby implementing the embodiment of the present invention. The storage medium of the computer program comprise a magnetic recording medium, an optical recording medium, a carrier wave medium, etc.
