BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments will be described in detail below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terms first, second, etc. may be used to describe various components, but the components are not limited by the terms, and the terms are used only for the purpose of distinguishing one component from another Is used.

According to the present invention, when a server collects information about a user and delivers a differentiated message to each user according to the related art, various collected personal information may be utilized for a purpose that the user does not intend, there is a risk of infringing the privacy of the user, and in order to further classify the characteristics of each user, a very large amount of personal information must be collected at the server or the like, The user is informed of the attributes of the user using the terminal and then provides the selected one or more messages to the user in consideration of the attributes of the user among the plurality of messages transmitted to the terminal, It is possible to grasp the attribute of the user in the terminal without transmitting it to the outside A user-customized message delivery terminal, a server, a system and a method, and a computer program therefor, which are capable of delivering differentiated messages according to characteristics of each user while preventing privacy invasion problems that may occur when information about a user is transmitted to the outside .

Hereinafter, a user-customized message delivery terminal, a server, a system and method, and a computer program therefor will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a user-customized message delivery system 100 according to an embodiment of the present invention. 1, a user-customized message delivery system 100 according to an exemplary embodiment of the present invention includes a server 120 that transmits a plurality of messages that can be selected and delivered according to attributes of a user And a terminal (120) that obtains one or more messages of the plurality of messages by considering attributes of the user using the information that can be obtained in the terminal itself (110) As shown in FIG.

At this time, the terminal 120 does not transmit information used for grasping the attribute of the user to the outside, but grasps the attribute of the user in itself.

Here, the terminals 120a and 120b may be implemented by various information processing apparatuses or communication apparatuses used by users. For example, a personal computer (PC), a notebook computer, a mobile phone, a tablet PC, a navigation device, a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP) A digital broadcast receiver, and the like. Of course, the present invention can be applied without any limitation as long as it is a device capable of receiving data from a server and appropriately processing the data, in addition to the above listed list.

The message may be a push message that is immediately delivered to a user, a short message service (SMS) message, a multimedia messaging service (MMS) message, or an in- a message of a messenger application such as an in-app message, a kakao chat message, and the like, and may further include various messages capable of delivering various contents such as text, sound, music, pictures, and videos to a user terminal.

In addition, the server 110 and the terminals 120a and 120b can exchange data through the communication network 130. [ For example, the communication network 130 may include an IP network capable of transmitting and receiving data through an Internet protocol, an All IP network for integrating different networks based on IP, a wireless broadband (Wibro) Network, a wireless LAN including a Wi-Fi network, a WPAN, a wired communication network, a High Speed Downlink Packet Access (HSDPA) network, and a satellite communication network. And may be applied without any particular limitation as long as it is a communication network capable of appropriately transmitting and receiving data between the server 110 and the terminals 120a and 120b in addition to the above listed networks.

The server 110 transmits a plurality of messages that can be selected and delivered according to the attributes of the terminal user to the terminal 120. The terminal 120 determines the attributes of the terminal user, It is possible to provide one or more messages corresponding to the attribute of the terminal user to the terminal user through the terminal 120. [

Referring to FIG. 2, a case where the server 110 transmits an advertisement message for an apparel article to the terminal 120 will be described in more detail. As shown in FIG. 2, the server 110 transmits four advertisement messages for each combination of male / female and adolescent / adult to each terminal 120 through the communication network 130 or the like as described above . Then, the terminal 120 receiving the four messages determines whether the attribute of the terminal user using the terminal is the male, the female, the adolescent or the adult, Message can be selected and provided.

In the case where the terminal user is a male terminal and a female terminal, an effective advertisement product and an advertisement method can be greatly changed. This also applies to the case of the age of the terminal user, The effect of the advertisement can be greatly enhanced. In particular, in the user-customized message delivery system 100 according to the embodiment of the present invention, the terminal 120 determines the attribute of the terminal user in itself, and transmits the personal information of the terminal user to the outside such as the server 110 It is possible to effectively prevent privacy infringement such as leakage of personal information of the terminal user and to grasp the attributes of the user by utilizing a very wide variety of information that can be acquired in the terminal 120 without risk of leakage of personal information , It is advantageous that the attributes of each user can be further subdivided and accurately calculated.

The attributes of the user as described above can be selected from a wide variety of values as needed, and further, the more detailed attributes can be selected. For example, it is possible to configure the attributes of the user by subdividing the above-mentioned adolescent / adult division into 10 or less, 20 to 30, 40 to 50, 60 or more, and furthermore, Seoul, Busan, Daegu, Gwangju, Daejeon, and others).

Accordingly, if the user can accurately grasp the attributes of the various subscribed users as described above, a more effective message can be provided accordingly, thereby maximizing the advertisement effect.

A method for grasping the attribute of the terminal user in the terminal 120 will be described in detail as follows. The terminal 120 classifies attributes of terminal users from information that can be obtained in the terminal 120 using a classifier. For example, in the case of FIG. 2, the gender classifier can determine whether the terminal user is male or female, and the age classifier can determine the age of the terminal user. Therefore, the gender classifier It is possible to select a message suitable for the user from among the four messages based on the attribute of the user.

At this time, the classifier may be software that performs an operation of selecting and classifying information required for itself among the information that can be acquired in the terminal 120, and may be implemented as hardware, if necessary.

The information that can be obtained in the terminal 120 can be converted into a feature and used by the classifier. The information in the terminal 120, which can be used to derive the factor, Can be utilized.

(1) Various sensor data in the terminal: ambient light sensor, proximity sensor, accelerator, GPS (Global Positioning System) data, Compass sensor, etc.

(2) Data on the usage history of the app running on the terminal: the type of app used by the terminal user, the pattern of usage of the app, the time of using the app, the period of using the app, the area used by the app, , Voice data, mobile web visit history, etc.

(3) Data generated while using an application running on the terminal: SNS profile such as Facebook, pictures, videos, text messages, contacts, emails, schedule, favorite restaurants,

For example, from the music data listened to by the terminal user, it is possible to guess the age or gender of the terminal user and analyze the gender of the terminal user by analyzing the voice data. In addition, if a Facebook profile or the like can be used, it is very easy to acquire information about various attributes of the terminal user. In such a case, however, additional information such as a procedure of receiving consent for information provision from each terminal user Problems may also appear.

The classifiers are classified using the above feature data, and these features can be expressed as a feature vector, and thus a factor vector F _i = ( f _{i , 1} , ..., f _{i , n} ). For example, suppose you use the four factors (feature), such as the number using the app often to view Videos, money supply for the last week, the last word "sister" for a week to the most frequently used in text messages, F _i = (Kakao Talk, drama, 60 minutes, 10 times).

When the value of the factor vector F _i for the user i is collected in the terminal 120, the classifier can be executed to determine the attribute of the terminal user from the factor vector. For example, the sex classifier S (F _i ) uses the value of the factor vector F _i of the terminal user i to determine whether the user i is male or female.

As described above, the classifier can be implemented not only in the gender classifier, but also in a wide variety of classes such as an age classifier, a classifier, a local classifier, and so on.

Furthermore, the classifier can grasp the attributes of the terminal user using the terminal by using various information that can be acquired in the terminal 120. In determining the factors to be used at this time, however, It is desirable to more appropriately select the factors to be used in consideration of whether or not it is the factor value, how efficiently the terminal user can be grasped, and the cost of the computational resources required to collect and process the factors. For example, when the user's text message data is used as a factor, it may be easy to grasp the gender of the terminal user, but it is preferable to consider that the risk of infringement of the terminal user's privacy may increase. On the other hand, when the gender of the terminal user is grasped by using the song reproduced by the terminal user as a factor, the risk of privacy invasion may be lowered, but the accuracy of the classification may be lowered.

In addition, the classifier can be implemented based on various machine learning techniques such as Logistics Regression, Bayesian network, AdaBoost, Support Vector Machine (SVM), and Naive Bayes.

In order to implement an effective classifier based on the above-described machine learning technique, a process of learning each classifier using learning data is required. At this time, the learning data includes a factor vector value _Fi and an attribute ). ≪ / RTI > I.e. can be expressed as the training data _{T = (F i (k)} , A i (k)), (k = 1, ..., m), where m corresponds to the number of learning data. For example, if the user of the terminal having the factor vector F _j of the terminal user who took the above-mentioned terminal is a man, then T = ((kakaotok, drama, 60 minutes, 10 times), man).

The attribute of the user corresponds to a set of result values to be discriminated by the classifier. For example, the attribute of the user in the sex classifier will be {M, F}, and the attribute of the user in the classifier { Seoul, Busan, Daegu, Gwangju, Daejeon, and others. Further, different classifiers also have attribute values of various users.

In addition, learning data for learning the classifier can be collected in various ways. For example, after collecting a large number of users having attributes of interested users (female in their twenties as a specific example) It is also possible to collect a large number of factor vectors from the terminal 120 of the terminal, and also, when the attribute of the terminal user can be grasped from a specific application (for example, by using the user profile information on the facebook, Or the age of the user can be known), it is also possible to collect a large amount of learning data from the terminal based on the attribute of the user.

Further, as an embodiment of the present invention, an algorithm for delivering a customized message to a user can be implemented in the form of a software development kit (SDK) library. The SDK may be delivered to a software manufacturing company using various messages such as an SMS, a messenger such as an MMS or a Kakao Talk, or an in-app message, and may be embedded in a program such as an app or an application. Then, the application including the SDK can be installed in the terminal 120 such as a user's smartphone through an App store or the like and can be driven.

FIG. 3 illustrates a configuration of a terminal 120 capable of delivering a customized message to a user according to an embodiment of the present invention. 3, the terminal 120 capable of delivering a customized message to a user according to an embodiment of the present invention includes a message receiving unit 122, a user attribute identifying unit 124, and a message providing unit 126, As shown in FIG.

Finally, the message providing unit 126 selects one or more messages among the plurality of messages in consideration of the attribute of the user, and provides the message to the user. At this time, the presentation determining unit 126 determines the attribute of the user without transmitting the information used to grasp the attribute of the user to the outside of the terminal 120, so that the user's personal information flows out It is possible to effectively reduce the risk of becoming.

In addition, in the user attribute determination unit 124, one or more classifiers operating on the basis of the machine learning may grasp the attributes of the user using information that can be acquired in the terminal 120, , The user attribute recognition unit 124 determines whether or not the data of the sensor in the terminal 120, the data on the usage history of the application 120 driven by the terminal 120, It is possible to grasp the attributes of the user by using at least one of the generated data.
