  In the conventional method, it is difficult to perform analysis necessary for target identification unless information on a field related to information to be distributed is acquired. For this reason, in order to accurately specify targets for various information, it is necessary to collect a large amount of information, which complicates the database configuration and analysis algorithm. Even when the distribution requester himself / herself designates the target condition, it is difficult to freely accept designation regarding the field of information to be transmitted.

  For example, in the above-mentioned patent document 1, the distribution requester (advertiser) is notified of the target attribute determined by the analysis processing in the server, and the distribution requester can automatically select the target based on the notification. However, there is no indication that the distribution requester can specify a specific image of the target.

  The present invention pays attention to the above-mentioned problem, and uses information having a correlation with a tendency of interest in various fields for target designation and narrowing down, thereby providing a target related to distribution of information in various fields with a simple system configuration. It is an object to make it possible to specify the target, and to make it easy for the distribution requester to specify the target condition.

  The information distribution server according to the present invention includes a registration unit in which unique information regarding a plurality of distribution destination candidates is registered, and a distribution destination registered in the registration unit in response to a distribution request notification from the terminal device of the distribution requester Based on target extraction means for extracting a target that matches the content of the delivery request notification from candidates and specific information registered in the registration means for the extracted target, the delivery request notification is sent to the terminal device of the target Information distribution means for distributing the information requested by.

  The server further acquires attribute information of the music file stored in the terminal device through communication with the terminal device of the delivery destination candidate registered in the registration unit, and acquires the acquired attribute information or the attribute There is provided attribute information processing means for storing the analysis information indicating the distribution destination candidate's music preference obtained from the information in association with the specific information of the distribution destination candidate. In addition, the target extraction unit receives each distribution destination candidate stored by the attribute information processing unit in response to receiving a distribution request notification including target designation information based on a music preference condition from the distribution requester's terminal device. The information that matches the specified information is extracted from the above information, and the target is specified by the unique information associated with the extracted information.

  According to the above configuration, the distribution destination candidate's terminal device extracts the attribute information of the music file acquired from the music distribution site or the like by the distribution destination candidate according to his / her preference and transmits it to the server. In the terminal device, by sending a distribution request notification including target designation information based on conditions relating to music preferences to the server, it is possible to specify the target according to the request of the distribution requester and distribute the requested information. . In addition to information related to the music field, it is possible to accurately specify a target for the distribution of information that is correlated with music preferences, such as other arts, fashion, miscellaneous goods, and service businesses.

  In a preferred embodiment of the server, the attribute information processing means obtains at least information related to the genre of the music stored in the file among the attribute information of the music file stored in the terminal device of the delivery destination candidate. To do. The target designation information also includes designation relating to a favorite music genre.

  According to the above-described embodiment, the distribution requester can set the target condition on the basis of the correlation between the specific information “favorite about music genre” and the information that he / she wants to distribute. Further, the server can use the genre classification of the original attribute information, and does not need to perform complicated analysis of the attribute information.

  The target extraction unit in another embodiment of the server extracts, as targets, distribution destination candidates who have acquired attribute information that matches the target designation information in the received distribution request notification for a predetermined number of times. According to this embodiment, numerical information representing user preferences can be obtained from attribute information of a plurality of music files, and a target can be easily extracted.

  In another embodiment of the server described above, attribute information is obtained from the music file stored in the device for the terminal device of the delivery destination candidate registered in the registration means or the terminal device accessed for registration. Program providing means is provided for transmitting a program for providing the terminal device with a function of extracting and transmitting to the server. According to this embodiment, the user can transmit the attribute information of the music data stored in the terminal device to the server as appropriate by downloading the above program after registration or at the time of registration.

  In the information distribution method according to the present invention, the transmission of the attribute information of the music file stored in the terminal device is received from each distribution destination candidate terminal device, and the distribution destination obtained from the received attribute information or the attribute information Analysis information indicating the music preference of the candidate is stored in association with the unique information for each candidate delivery destination. Then, a distribution request notification including target designation information according to a condition relating to music preference is received from the distribution requester, and it matches the designation information in the distribution request notification from the information for each distribution destination candidate stored. Information is extracted, and a target is specified by specific information associated with the extracted information.

  In the above method, the delivery request notification from the delivery requester can be received through communication with the terminal device of the delivery requester, but not limited to this, depending on the oral or written notification from the delivery requester. A method of inputting the contents of the notification to the server may be adopted. In addition to distributing information to distribution destination candidates identified as targets to terminal devices to which the music file attribute information has been transmitted, authentication using a password, e-mail notification, etc. The information to be distributed may be accessible from any terminal device. Further, instead of data transmission, information processing for sending a paper medium on which distribution information is printed to a target distribution destination candidate may be performed.

  According to the present invention, the distribution requester himself / herself easily designates the target related to information distribution in various fields by using the attribute information of the music data acquired by each distribution destination candidate according to his / her preference. It is possible to extract a target that matches the indication. In addition, since it is not necessary to collect information on various fields from the distribution requester, the database configuration and information processing can be simplified, and system development is facilitated.

It is a figure which shows the structural example of the input form transmitted to a customer terminal. It is a flowchart which shows the procedure of the process performed with a server for the information delivery to the target user terminal.

  FIG. 1 shows the functions of an information distribution server 1 to which the present invention is applied, together with the relationship with a terminal device. The information distribution server 1 (hereinafter simply referred to as “server 1”) receives distribution requests for information on products and services from various business operators (hereinafter referred to as “customers”), and requests the requested information. It was developed for the purpose of executing a service that is distributed to people who meet the conditions specified by.

  The server 1 includes a general user terminal device 2 (hereinafter referred to as “user terminal 2”) and a customer terminal device 3 (hereinafter referred to as “customer terminal 3”), which are information delivery destination candidates. Connected via the internet. Any of the terminal devices 2 and 3 may be of any type as long as they have an input / output function and can display information transmitted from the server 1, such as personal computers, smartphones, and tablet terminals.

  The user terminal 2 has a function for providing the server 1 with information necessary for specifying a distribution target by the program provided from the server 1 (music attribute information extraction unit 21, music attribute information transmission unit 22). In addition, an application 20 having a function (content receiving unit 23, content reproduction processing unit 24) for receiving the distribution of content data as specific information from the server 1 and reproducing the content based on this information is incorporated. On the other hand, the customer terminal 3 is not provided with a special function, and a delivery request notification is transmitted to the server 1 via an input form (see FIG. 5) described later.

  The server 1 includes a user information storage unit 10A, an analysis table storage unit 10B, a distribution information storage unit 10C, a distribution management table storage unit 10D, and a customer information storage unit in addition to the application providing unit 13 that transmits the above-described program to the user terminal 2. 10E and the like, a user registration processing unit 11, an attribute information processing unit 12, a customer registration processing unit 14, a distribution request reception unit 15, a target extraction unit 16, a management table creation unit 17, a distribution processing unit 18, and the like. The server 1 can also distribute information common to all registered users to all users in addition to information distribution performed in response to designation of conditions for distribution destinations.

  The application providing unit 13 transmits a program constituting the application to the user terminal 2 in response to a download request from the new user terminal 2. The user registration processing unit 11 sends a message prompting a registration procedure for information distribution to the user terminal 2 that has received the program distribution, and the user specific information transmitted from the user terminal 2 in response to this message Register in the information storage unit 10A. Further, the user registration processing unit 11 executes an authentication process using the registration information in the user information storage unit 10A for the login from the user terminal 2 for which registration has been completed. As for the processing at the time of user registration, contrary to the above, the application program can be provided after the registration in the user information storage unit 10A is completed.

  In the user information storage unit 10A of this embodiment, for each user, as shown in FIG. 2A, four types of user ID and password for login, user name, and e-mail address are registered as basic information. ing. Arbitrary information other than the basic information can be registered in the user information storage unit 10A.

  The attribute information processing unit 12 accepts transmission of music file attribute information (details will be described later) from the music attribute information transmission unit 22 of the user terminal 2. Further, the attribute information processing unit 12 analyzes the acquired attribute information, creates an analysis table as shown in FIG. 2B, and stores this in the analysis table storage unit 10B. The analysis table is linked to the basic information using the user ID as a key.

  The customer registration processing unit 14 receives specific information such as a customer ID, a password, a business office name, and an e-mail address in response to an access from the new customer terminal 3, and registers them in the customer information storage unit 10E. Further, in response to a login from the registered customer terminal 3, an authentication process using the registration information in the customer information storage unit 10E is executed.

  The distribution request reception unit 15 receives distribution target information and distribution condition designation information from the customer terminal 3 for which the above authentication has been completed. The information to be distributed includes content data such as image data and audio data, and mail document data for notification. The distribution request reception unit 15 sets a folder with a unique identification code (hereinafter referred to as “content ID”) for each request in the distribution information storage unit 10C, and the received content data and mail document data are stored in this folder. Is stored (see FIG. 2C).

  The distribution condition designation information includes information indicating a target to which information is distributed and the date and time of the first notification. The target extraction unit 16 extracts an analysis table having contents that match the target designation information from the analysis table storage unit 10B, and specifies a user ID stored in the extracted table as information representing the target. As shown in FIG. 2D, the management table creation unit 17 creates a delivery management table that represents the correspondence between the content ID of each piece of information stored in the delivery information storage unit 10C, the notification date and time, and the target designation. .

  The distribution processing unit 18 refers to the above distribution management table and distributes an e-mail including link information to the storage location (address) of the content data to be distributed to the target of the information that has been notified. When access to the link destination is executed in the user terminal 2 that has received this e-mail, the content data stored in the link destination is transmitted from the distribution processing unit 18 of the server 1 after user authentication in the server 1. The In the user terminal 2 that has received the content data, the content reproduction processing unit 24 performs reproduction processing (image display, audio output, etc.) according to the type of content data.

  The attribute information which is the original information of the analysis table in this embodiment is extracted from the music file stored in the music folder 25 of the user terminal 2 by the music attribute information extracting unit 21 of the user terminal 2. The music folder 25 is provided in the user terminal 2 as standard, and the music file is acquired by the user from a music providing site or the like.

  The music file attribute information includes a plurality of types of information such as a song name, a composer name, a performer name, a genre, a release year, and a performance time. Although the entire attribute information is extracted from the user terminal 2 and transmitted to the server 1, the attribute information processing unit 12 of the server 1 extracts genre information and release year information from the received attribute information. Create an analysis table.

  As shown in FIG. 2B, the analysis table has a configuration in which the combinations of genres and release years are divided into a plurality of groups, and the frequency of acquiring attribute information that applies to each group is stored. However, unlike the “classic” in the illustrated example, one group may be set only by genre without being classified by age.

  Even in the designation of the target accepted by the distribution request accepting unit 15, the target is specified by the genre or the combination of the genre and the age according to the configuration of the analysis table (see the target designation column 33 in FIG. 5). However, the information that can be accepted as a distribution target is not limited to the music field, but can be expressed in various fields that can represent people who are suitable for the target, such as clothing, miscellaneous goods, furniture, books, movies, and theater. Can be accepted.

  As a specific example, for example, “1970s rock enthusiasts” is designated as a target for distributing product introductions of vintage jeans shops, and “1960s jazz lovers” is targeted as a target for distributing Bourbon whiskey advertisements. “Classic lovers” can be designated as the target to designate and distribute information about high-end imported furniture exhibitions. As in these examples, for information that shows a correlation between interest in the information to be distributed and music preference, narrow down the target based on general items such as age, occupation, and residential area. The reaction from the user side to the information to be distributed can be obtained with a much higher probability.

  In addition, by collecting specific information as attribute information of music files, it is possible to extract information distribution targets regarding these fields without collecting user information regarding various other fields. The server 1 can construct a data source necessary for target extraction by creating an analysis table having a simple configuration of frequency data for each combination of genre and age from the attribute information collected from each user terminal 2. Since it is not necessary to perform complicated information processing for extraction, the system development effort can be reduced.

  FIG. 3 shows the procedure of processing executed by the application 20 of the user terminal 2 and the procedure of processing executed by the server 1 in response to login from the user terminal 2 in association with each other.

  The login from the user terminal 2 to the server 1 is performed immediately after the user registration is completed, as well as when the link information of the e-mail is accessed. The following description relates to login immediately after user registration.

  When the login from the user terminal 2 (step S1) and the authentication process in the server 1 (step S11) are completed, the music attribute information extraction unit 21 searches the music folder 25 in the user terminal 2 (step S2). . All the music files found by the search at the first login are determined to be new files (step S3 is “YES”), and the attribute information of each music file is extracted by the music attribute information extraction unit 21 (step S4). . The music piece attribute information transmission unit 22 transmits the extracted attribute information to the server 1 (step S5), and stores the transmission date and time in a memory (not shown) of the user terminal 2 (step S6).

  In the server 1, the attribute information processing unit 12 receives the above transmission ("YES" in step S12), and extracts information on the genre and release year from the received attribute information (step S13).

  Here, the attribute information processing unit 12 checks whether or not the analysis table including the user ID authenticated in step S11 is registered in the analysis table storage unit 10B. Immediately after accepting the first login, since the corresponding analysis table is not registered, step S14 is “NO”. In response to this determination, the attribute information processing unit 12 creates a new analysis table in which the frequency data based on the authenticated user ID and the extraction result in step 13 is stored, and registers the new analysis table in the analysis table storage unit 10B.

  In the user terminal 2 at the time of the first login, step S7 after the execution of steps S1 to S6 is “YES”, and the process ends. The server 1 that has received the login also ends the process for the first login upon registration of the analysis table in step S15.

  FIG. 4 shows the flow of processing executed by the server 1 for login from the customer terminal 3. In this process, after authenticating the logged-in customer terminal 3 (step S21), the distribution request receiving unit 15 transmits the input form to the customer terminal 3, and transmits the content data and the mail document data, and the target and the notification date / time. The designation is accepted (step S22).

  FIG. 5 shows an example of the configuration of the input form sent to the customer terminal 3. The mail document data input field 30, the content data upload button 31, the notification date / time specification input field 32, and the target specification input field 33 etc. are provided. The notification date designation input field 32 is configured such that the selection can be freely changed from the initial state in which the current date is selected. The target designation input field 33 is configured to select one genre as an indispensable selection item and to arbitrarily select the age related to the selected genre (a plurality of selections are possible). In FIG. 5, only one genre can be selected for convenience of illustration, but a plurality of genres can be designated.

  Returning to FIG. When the reception process via the input form is completed, the distribution request reception unit 15 assigns a common content ID to the received content data and mail document data, and creates a new folder with the content ID as a folder name. The content information and the mail document data are stored in the distribution information storage unit 10C and stored in the folder (step S23).

  The target extraction unit 16 performs a search for the analysis table storage unit 10B to search for an analysis table having contents that match the target designation information received in step S22. Specifically, using the genre indicated by the target designation information or the combination of the genre and the age as a search key, the analysis table storage unit 10B stores a frequency equal to or higher than a predetermined reference value for the search key. Search the analysis table. Then, the user ID is extracted from the found analysis table (step S24).

  The management table creation unit 17 creates a new record including the content ID set in step S23, the notification date and time accepted in step 22 and the user ID extracted in step S24, and stores the new record in the distribution management table. The data is stored in the storage unit 10D (see FIG. 2D) (step S25). With this storage, the process for logging in the customer terminal 3 is completed.

  FIG. 6 shows a processing procedure for sending a notification by e-mail to the user specified as the target by the procedure of FIG.

  This process is mainly executed by the distribution processing unit 18. The distribution processing unit 18 appropriately checks the notification date and time in the distribution management table (step S31), and determines that the remaining time until the arrival of one of the notification dates and times has entered a predetermined threshold range (for example, about several minutes). Then (step 32 is “YES”), steps S33 to S36 are executed.

  In step S33, the content ID and the user ID are read from the record in which the notification date / time is within the threshold range. In step S34, the user information storage unit 10A is searched using the read user ID, and an e-mail address corresponding to the user ID is acquired.

  In step S35, the distribution information storage unit 10C is searched using the content ID read in step S33, the mail document data is read from the folder having the content ID as the folder name, and the address (url) of the content data in the folder ) To get.

  In step S36, an e-mail including the mail document data and the link information to the content data address is created and transmitted to the e-mail address acquired in step S34.

  Here, with reference to FIG. 3 again, a process executed by the user terminal 2 and the server 1 when the user terminal 2 that has received the above-described mail accesses the link destination will be described.

  Also in the user terminal 2 in this case, the music folder 25 is searched by the music attribute information extraction unit 21 after logging in to the server 1. If a music file downloaded after the transmission date and time saved in step S6 at the previous login is found in this search (step S3 is “YES”), the attribute information of the music file is extracted and transmitted to the server 1. (Steps S4 and S5), the transmission date and time is stored (Step S6).

  In the server 1, after the attribute information processing unit 12 receives the attribute information ("YES" in step S12), the information related to the genre and the release year is extracted from the received attribute information in the same manner as when the first login is accepted. (Step S13). Further, the attribute information processing unit 12 searches the analysis table storage unit 10B to find an analysis table corresponding to the logged-in user ID (“YES” in step S14), and the information extracted from the analysis table in step S13 (Step S16).

  If a new music file is not stored in the user terminal 2, the processes in steps 4 to S6 of the user terminal 2 are skipped, and the server 1 also becomes “NO” in step S12, and steps S13 and S14. , S16 is skipped.

  In the user terminal 2 that has finished the processing related to the attribute information, step S7 becomes “NO”, the process proceeds to step S8, and the content reception unit 23 transmits a content data transmission request to the server 1. This transmission request includes an address corresponding to the access to the mail reception from the previous server 1.

  In the server 1, the distribution processing unit 18 receives the above transmission request ("YES" in step S17), and refers to the distribution management table by the content ID corresponding to the address in the transmission request, and the user terminal that made the transmission request Check whether 2 is a valid target. If it is confirmed that the target is valid (step S18 is “YES”), the distribution processing unit 18 reads the requested content data from the distribution information storage unit 10C and transmits it to the user terminal 2 (step S19). Note that the determination in step S18 is not necessarily required, and the content data may be transmitted with confirmation that the content data corresponding to the link destination to the transmission request is stored.

  In the user terminal 2, after the content data is received by the content receiver 23 ("YES" in step S9), the content playback processing unit 24 plays back the content based on the content data (step S10).

  In the above embodiment, each time the user terminal 2 logs in to the server 1, the music folder 25 is searched, and when attribute information of a new music file is found, it is immediately stored in the server 1. However, the present invention is not limited to this, and the search or transmission may be performed only when a predetermined period has elapsed since the previous transmission.

  Further, in the above embodiment, all the attribute information in the music file held by the user terminal 2 is transmitted to the server 1, while the information necessary for creating the analysis table in the server 1 (information on the genre and release year). However, only information necessary for creating the analysis table may be extracted on the user terminal 2 side.

  The information used to create the analysis table is not limited to the genre and release year, and for example, the frequency may be obtained for each specific name of the composer or performer. In that case, in the specification of the target, the specification with the name of the composer or the performer is accepted, and by searching the analysis table in which the frequency more than the reference value is stored for the specified name, A user can be specified.

  Along with the analysis table having the configuration shown in FIG. 2B, the original attribute information is stored in a format that can be read for each user ID, and when a detailed designation is accepted, the stored attribute information group is analyzed. Thus, a user who matches the specified content may be specified. Alternatively, without providing an analysis table, the attribute information itself transmitted from the user terminal 2 is stored for each user, and the stored information is analyzed to identify a user who matches the specified content from the customer terminal 3. Also good.

  When information other than basic information (age, gender, occupation, place of residence, etc.) is registered in the user information storage unit 10A, by specifying the conditions related to these information in addition to the conditions related to the preference of music, Target conditions may be narrowed down in more detail. Further, when the user terminal 2 is a device having a GPS function, the designation of the area to be distributed from the customer terminal 3 is accepted, or the area to which the distribution requester's office belongs is acquired, and these designation or acquisition The target may be specified based on the area and the location information acquired from each user terminal 2.

  In the above embodiment, in order to reliably deliver information to the user extracted as a target and simultaneously acquire the attribute information of the music file newly saved by the user, an e-mail with a link to content data is set. However, if it is not necessary to consider the purpose, the login authentication may be eliminated and the content data may be transmitted immediately in response to the access to the link.

  The method of distributing information to the user extracted as a target is not limited to the two-stage notification as in the above embodiment. For example, after login authentication, the distribution management table is searched with the authenticated user ID, and if there is content data that is associated with this user ID as a target and the time of notification has arrived, it is read out and the user terminal 2 You may make it transmit to. In addition, when such a change is made, the data within a certain period after being stored in the distribution management table is validated (or data from the customer terminal 3 is not received) without accepting designation of the date and time of notification from the customer terminal 3. Only valid data may be distributed in response to designation of the period for which When an address is registered in the user information storage unit 10A for each user, instead of distributing the content data, a printed matter on which information to be distributed is recorded may be sent by mail to the target user. .

  When the login authentication when the user terminal 2 accesses the server 1 is eliminated, each user may be specified by the identification number of the user terminal 2 (hereinafter referred to as “terminal ID”). For example, the terminal ID is stored as basic information in the user information storage unit 10A, and the analysis table of each user is linked to the basic information using the terminal ID as a key, and the target can be specified by the terminal ID. In this case, even if the basic information is only the user terminal ID, when the user terminal 2 accesses the server 1, the distribution management table is searched with the terminal ID, and the content data associated with the terminal ID is targeted. Can be distributed to the user terminal 2.

  When standard image data or audio data is transmitted as the content data, the content receiving unit 23 and the content reproduction processing unit 24 are not provided in the dedicated application 20, and the functions provided as standard on the user terminal 2 are provided. It may be used to receive and play back content data. However, when information distribution using special content such as augmented reality display is performed, it is desirable to provide an application program including a dedicated content receiving unit 23 and content reproduction processing unit 24 corresponding to the distributed content data.

  In the case of distributing information using augmented reality display content, each user is provided with an object (for example, a membership registration card) on which a pattern that triggers augmented reality display is written in advance, and the user terminal 2 having a photographing function. In response to the above pattern being photographed, automatic login to the server 1 may be executed, and content data found by a search using a user ID authenticated by this login may be transmitted to the user terminal 2. According to such a method, even if the same pattern is photographed, information of different contents is distributed depending on the photographer and the date and time of photographing, so that the user's interest is increased and active access to the server 1 is achieved. Can be urged.

  In addition, the application 20 of the user terminal 2 is urged to access the server 1 by including tools that are attractive to the user, such as an online game, an application for SNS, and an application for distributing general information such as news. You can also If it does in this way, the attribute information of a music file can be acquired from the user terminal 2 which accessed, and the information by which the said user terminal 2 was set as the target can be delivered suitably.

  When it is possible to obtain information about preferences related to fields other than music from each user, both the information and attribute information of the music file are accumulated for each user, and the accumulated information is analyzed to analyze each genre. It is also possible to identify products and services that are likely to be of interest to people who like music, and to identify the target image of information distribution in various fields according to the genre of music preference based on the analysis results You may do it.)

  Furthermore, based on the above specific result, for each music genre, it is possible to collect and distribute information that is likely to be of interest to people who like the music of that genre. On the contrary, information of a music genre that people are likely to like may be distributed to people who have a certain common preference regarding a predetermined field other than music. The distribution of such information is not limited to the users registered in the server 1, and may be distributed to unregistered people who have a preference that matches the content specified as the distribution destination.

  In addition, based on the above-mentioned specific results, companies in various fields can introduce the person image suitable for each information distribution destination by representing their favorite music genre, which can be used for sales promotion activities. . For example, to inform a business operator who operates a store, inform them of the genre of music that is likely to be preferred by people interested in the products and services handled by the store, and propose to use the music of that genre as BGM Can do. It is also possible to suggest that a concert flyer be distributed at the event venue to the organizer of a concert about a music genre that is likely to be of interest to visitors to a given event.
