Description

Multi-party personal information sharing and management system {SYSTEM FOR SHARING AND MANAGING PERSONAL INFORMATION FOR MULTI-USER}

The present invention relates to a personal information management system, and more particularly, to allow a person to share information with a specific person or a common interest group, so that the collection and update of the information is made by multiple persons within the specific person or the common interest group. A personal information sharing and management system.

Conventionally, a personal information management system (PIMS) implemented in a web, a PC, an electronic notebook, a portable telephone, a PDA, a pocket PC, or the like performs personal information management. It is only used to manage the back, and it was not possible to automatically change the information according to other people's schedule change or information change related to the specific individual's schedule.

In other words, the conventional PIMS has a 'closed' and 'personal' structure, and functions only as a means of storing and reproducing personal information, so that each individual has to work to input, modify and confirm his or her own schedule.

In addition, if another person's schedule changes in relation to their schedule, if they are not notified of the change, they may lose the opportunity to update their schedule, which may lead to loopholes in the schedule management, even if the change is notified. Checking and updating the related matters one by one causes inconvenience to the user in managing his / her schedule, and if an error occurs in the input process, too much damage may occur due to wrong schedule management.

Accordingly, the present invention eliminates many inconveniences caused by only one individual managing his or her own information by integrating the network concept into the existing PIMS, which has been utilized as an auxiliary storage means, and facilitates the sharing and management of multilateral personal information. It is possible to manage personal information efficiently.

Furthermore, service providers who want to provide specific information on the network can provide more precise personalized services by utilizing a multi-user information management system (MIMS). Can be used to market more targeted advertising marketing.

Accordingly, it is an object of the present invention to provide a system that allows an individual to efficiently manage information in cooperation with a specific person or a common interest group.

Another object of the present invention is to provide a personalized service suitable for each individual's disposition by utilizing a characteristic of sharing personal information among MIMS users.

As shown in FIG. 1A, the overall environment of the multi-party personal information sharing and management system is largely comprised of three types: a server, a client, and a communication environment.

The server consists of the MIMS server (R800), which is the center of service provision, the MIMS gateway server (R600) for converting the data format according to various connection environments into a data format suitable for the MIMS server, and the administrator console (R900) for managing the server. ) The MIMS server R800 and the MIMS gateway server R600 are interconnected through a plurality of channels (TCP / IP port) R700, and the administrator console R900 connects them according to priority.

As shown in FIG. 1A, there are two types of users across a server and a communication environment.

First, the user client R100 refers to information devices (personal portable information terminals (PDA, Post-PC, etc.), mobile phones, laptops, desktop PCs connected to the network, and Internet TV) that can be connected to the network. The user client R100 connects to the MIMS server R800 using the network connection function that can be used respectively. The connection methods are various, such as X.25, TCP / IP, WAP, WEB, PSTN, CDMA, GSM, etc., and the user client R100 is assigned to each method for connection with the MIMS server R800. The user client R100 connects to the MIMS server R800 with a plurality of routes within a range that its performance allows. The user client R100 connects to the MIMS server R800 and performs operations such as viewing and changing of personal information.

Next, the content provider client R200 mainly refers to companies that want to provide information to the user. They can access the MIMS server R800 in the same manner as the user client R100 and provide the information. However, they are mainly connected to the MIMS server R800 using the wired Internet due to the large amount of information to be provided. They access the MIMS server (R800) to view the personal information allowed to access, and provide information appropriate to each individual's disposition based on the personal information. Using this function, the present invention provides a marketing system.

Figure 1b is a block diagram logically implemented a multi-party personal information sharing and management system according to an embodiment of the present invention.

As shown in Fig. 1B, the multi-party personal information sharing and management system is largely composed of a client C100 and a server S100.

The client C100 includes a PIM database C500 that stores personal information, a client engine C200 that includes an actual processing module, and a wireless connection N100 and a wired connection N200. Client C100 connects to the server and synchronizes its PIM database with the PIM backup database on the server. Thus, other users can obtain the effect of viewing and changing the information of the client's PIM database by viewing and changing the server's PIM backup database.

Next, the server S100 synchronizes and manages alarms of a listener S200 that receives a request from the client C100, a server scheduler S250 that schedules processes on the server S100, and an alarm of the clients C100. Manager (S270), (S400), the server engine (S450) including the actual processing module and service module, push content database (S600) containing general information and analysis information about the user, and documents or data of the user It contains a repository (S700), a PIM backup database (S800) that backs up personal information, and an intelligent agent (S900) that analyzes, learns, reports, and applies user usage types. Each component of the client and the server will be described in detail with reference to the accompanying drawings.

The PIM database includes an alarm table (C502) that contains alarm information, a configuration file (C504) that contains configuration information, a schedule database (C506) that contains schedule information, a contact database (C508) that contains contact information, and job information. Task database containing information (C510), memo database containing memo information (C512), category table containing information for classifying each information (C514), and project ID table containing unique numbers of each project (C516). A project database containing project information (C518), a project template containing project temporary information (C520), a PIM database pool acting as a cache for the PIM database (C522), and a synchronization table for synchronization with the server (C524). Log for the agent (C526) containing client log information for the agent. That includes a repository index (C528) which contains the index for other personal information.

The PIM database resides on the client and server respectively, and the two databases are synchronized when the client is started. Thus, other users who have a certain connection with a specific person and are allowed to access can view and change the PIM database of the client synchronized with it by viewing and changing the personal information recorded in the PIM database of the server.

On the other hand, even when the client is not connected to the network, the server's PIM database can be viewed and changed, and the server has an alarm function that notifies the client by SMS, e-mail, or the like. Later, when the client is connected to the server, the two PIM databases are synchronized, so that personal information of a specific person can be automatically updated according to the schedule of another person.

In the above, we have mentioned some relations among users, which will allow each individual to form a project group around a specific area of interest and invite others to the project group. The groups thus formed have a relationship of mutually managing personal information. The project table, project database, and project template described above are the components required for the server and client to perform these functions.

5 is a configuration diagram of the push content database shown in FIG. 1B.

The push content database S600 is a database for providing advertisement or personalized information. The push content database (S600) is a content pool (S604) serving as a cache, a content index (S606), which is an index of content, a content category (S608) containing content information of contents, and a content of content. A content ID table (S610) containing the numbers, and a content database (S612) containing the contents of the contents.

The push content service refers to a service that delivers information of a push content database containing a newly combined advertisement or personalized information to a client based on user information, and details thereof will be described with reference to FIG. 10.

So far, the detailed configuration of the system according to one aspect of the present invention has been described. In the system of the above-described configuration, when the user runs the client, the process of initializing the client environment is performed according to the data on the server by checking the ID and the like, and when the process is finished, the user needs the functions on the client screen. Will be able to perform them.

The following describes the operation of the client and the detailed operation of each function with reference to the drawings.

6 is a flowchart illustrating a data processing process in the client illustrated in FIG. 1B.

When the client is running (302), it first initializes the browser (304), and checks for the existence of a client ID and whether a password error (306). If there is no error, the client loads the environment setting (310), and if there is an error, displays a user registration guide message, performs a subscription process (312), and loads the environment setting (310).

Thereafter, the PIM database is loaded (318) and a startup routine is performed (320) according to the set environment. When the startup routine ends, the display of the client screen is displayed (340) and the driving of the client is terminated (342).

In the above-described startup routine, the routine first checks whether the client is connected to the network (322), and if so, synchronizes the PIM data on the server with the PIM data on the client (326). Then, synchronize the push data in the data push client module on the client according to the updated data of the push content database on the server (328), and check the connection status of requests and notifications, emails, and other users from other users. (330 to 334). Thereafter, the alarm is finally performed (336) and the startup routine is terminated (338). If it is not connected to the network, it immediately executes an alarm and terminates the startup routine. The alarm function will be described with reference to FIG. 9.

7 is a flowchart illustrating a method of reviewing another user's schedule by using the system of FIG. 1B.

First, a user who wants to review another user's schedule inputs another user's ID (802). It is determined whether the user corresponding to the user ID is online (804), and if the user is online, the client accesses the client of the user (806). If the user is not online or cannot access the client of the user, the server accesses the server (808). If the connection is not established, a schedule incapable of reviewing message is displayed and the operation ends (810). However, if the connection is made, the schedule data of the corresponding user ID is requested according to the format of the outgoing message 880 for requesting the schedule review (812). The outgoing message 880 has a format that includes a request user ID 881, a schedule owner ID 882, a request period 883, and the like.

Thereafter, if the authentication succeeds through authentication of the corresponding user (814), the schedule data is received according to the received message 890 format for schedule review (818). The schedule reception message 890 has a format including a schedule owner ID 891, a schedule full period 892, a schedule number 894, a schedule start time 895, a schedule end time 896, and the like. However, if authentication fails, a user authentication failure message is displayed (816) and terminates.

Finally, the received schedule data is output to the screen (820) and the other user's schedule review ends.

8A and 8B are flowcharts illustrating a method of requesting, modifying, and deleting an appointment by another person using the system shown in FIG. 1B, and FIGS. 8C, 8D, and 8E are screen configurations for explaining the flowcharts of FIGS. 8A and 8B. It is also.

To request an appointment, first select an appointment application from among the appointment, modification, and deletion of an appointment (900) to display an appointment request screen (1030) of the type shown in FIG. 8C (902). Thereafter, the user screen is displayed on the application screen (906), the contents of the appointment with the counterpart user are entered (908), and the appointment request button 1043 is clicked (910). Thereafter, the appointment request message M1 is sent to the module of FIG. 8B.

To modify an appointment, first select an appointment modification (900) among the application, modification, and deletion of an appointment (900) to display an appointment modification screen (1050) of the form shown in FIG. 8D (914), and then create an appointment modification content ( 916, click the modify appointment button 1063 (918). Thereafter, an appointment modification message M2 is sent to the module of FIG. 8B (920).

Click (924). The appointment deletion message M3 is then sent to the module of FIG. 8B (926).

The module of FIG. 8B, which receives the message M1 to M3 about the appointment, checks whether the user is set to notify by e-mail (928), and if so, sends the message by e-mail (930). If not, the method checks whether the user is a MIMS user (932), and if the user is a MIMS user, proceeds to step 934, and if the user is not a MIMS user, sends a message by e-mail and terminates (931). ). In step 934 of checking whether the user is online, the appointment management history is registered in the PIM database of the user on the server if the client is online (936).

After registering appointment management details in the user's PIM database, if the SMS notification is checked in the input screen (944), the SMS message is transmitted only to the user whose mobile phone number is input (946). If offline, an attempt is made to connect to the server (938). If the connection fails (940), a server connection failure message is displayed (942). Thereafter, if the user still remains (948), a list of failed notification users is displayed (950), and then asked whether or not to automatically notify (952). If the automatic notification is to be made (956), it is registered with the PIM scheduler (C210) (958). If not, the SMS message is sent only to users with Mobile numbers (946). In step 948, which asks whether the user remains, if there is no user, the process ends immediately. So far, the operation of the function of applying, modifying and deleting an appointment by using the system according to an aspect of the present invention has been described.

9 is a diagram illustrating a system implementing an alarm function using the system of FIG. 1B.

The alarm function according to the present invention refers to a function of automatically notifying an individual of a relevant update when personal information is updated, and between the alarm managers C202 and S270 of the client C100 and the server S100. Is performed by communication. The alarm engine C202-1 of the client C100 performs an alarm function with reference to the alarm database C202-2, and the alarm manager S270 of the server S100 applies an alarm to another user or uses a different function. It is a means for synchronizing and sharing alarm information with a user. In addition, since there is an alarm manager S270 of the server S100, a consistent alarm function may be implemented in a wired / wireless complex environment.

Through the alarm function of the wired / wireless complex environment, the system enables real-time communication such as information sharing and schedule discussion among users. In a hardware environment such as a POST-PC or a wireless terminal such as an existing on-line capable desktop PC or a PDA used in a stand-alone state, when an individual accesses and manages the PIM database by itself, Variations in time can cause loopholes in information management.

However, by using the alarm function provided by the present invention, it is possible to overcome the error of the information according to the time deviation between users with respect to information that must be held jointly by multiple users in real time, thereby maximizing the utility value of the PIM data do.

In addition, PIM Data allows users to receive wirelessly when they need to be notified of their schedules or TASK information, even if they are not online through a desktop PC. The physical limitations in operating as an auxiliary storage device can be removed.

Another aspect of the present invention is a wired / wireless marketing system comprising: a client capable of inputting and outputting information; A server supporting a multi-party network between the clients and enabling joint management and sharing of personal information at the request of the clients; And a data format automatic converter connected between the client and the server to enable the transfer of data between the client and the server by automatically converting various data formats according to various types of the client terminals into a predetermined format. The client includes a client engine for implementing a multi-party personal information sharing and management system, and a PIM database, which is a personal information database. The server provides a system and server engine for supporting a multi-party network, and synchronization of data with the client's PIM database. And a content database formed by information input from the client terminal of a service provider to implement a real-time on-demand service. Jean has a function of searching the contents database according to a search word input by the user through the client terminal and transmitting related information to the user.

An example of this marketing system will be described with reference to FIG.

The push content service refers to a service that provides a specific individual with information or advertisements that the service provider combines based on the specific personal information. The combined information or advertisement is stored in the push content database S600 of the server engine S450 through the client of the service provider, and the stored information is stored by the startup routine 320 when the user client is driven. Is sent to the data push client module C218 of the engine C200. Through this function, the present invention can provide a marketing system.

FIG. 11 is a diagram illustrating a system for implementing an interworking function with a web bulletin board by using a system according to an embodiment of the present invention.

First, the communication channel between members of the MIMS user group registered as a member is more diversified in consideration of the environmental constraints of users who do not have the client C100 of the system or who are registered in the system in a mobile situation. Secondly, the purpose is to allow members to open temporary communication channels between members and nonmembers more effectively to meet their purpose and utility. In other words, anyone can indirectly access MIMS data through bulletin boards on the web board and enable communication based on it.

For such a function, the server engine S450 includes a web board gateway S460 for interworking with the web bulletin board in the MIMS server S100 as in a general web bulletin board system.

Referring to the operation of this function, when a MIMS user or a non-user accesses a bulletin board on a web board, and views or modifies personal information according to his or her authority, the web board gateway S460 in the server engine S450 is displayed. The modified personal information transmitted to the server through the data getter module S460-2 is transferred to the client engine C200 of the client C100 through the data posting module S460-1 of the web board gateway S460. Is passed to the data get module C222 in the < RTI ID = 0.0 > By doing so, it is possible to view and modify personal information using the MIMS system even when the client C100 is not available.

FIG. 12 is a system configuration diagram illustrating an information sharing function between users of the client C100 using the system illustrated in FIG. 1B.

First, a client user sets up a user to share information with. Thereafter, when another user requests information sharing such as viewing or changing information, the permission manager C216 of the client engine C200 checks the sharing authority to determine whether to share the information between the users of the client C100. At this time, even when the user is offline, the authority setting details set by the client user so that other users can access the user's information in the server S100 according to the same sharing authority that is set in the client C100 when online. Is stored in the permission database S468 via the permission manager S454 in the server engine S450 of the server S100. By doing so, it is possible to maintain consistency of information sharing authority.
