Description

TECHNICAL FIELD [0001] The present invention relates to an NFC-based relational diffusion method,

The present invention relates to an NFC-based relational diffusion method and apparatus, and more particularly, to a method and apparatus for distributing content seeding (SEEDING) to a smart terminal of a user including a smart phone and a tablet based on Near Field Communication Distributes content through each user's smart terminal, spreads contents among users to enhance content propagation effect, collects and analyzes data including user codes from smart terminals that have performed NFC, and reports them to the client The present invention relates to an NFC-based relational diffusion method and apparatus thereof.

CPI (Cost Per Install) is a method of paying for content distribution according to the number of devices installed with applications corresponding to the contents when distributing contents in a mobile environment. It is a kind of cost per action (CPA), which is the way in which a price is paid whenever an action is taken.

As information technology has developed and interactive communication with consumers has become possible, contents distribution techniques that focus on the number of times of exposure to the public have also changed. Clients wanted consumers to take their own actions, and as a result, the criteria for content distribution enforcement focused not only on content exposure, but also on behaviors such as membership or game installation.

In the market situation as described above, for example, when the content is a mobile game, the CPI has a high probability of enjoying the game rather than the simple exposure because the consumer installs the game application, which increases the efficiency of the content distribution cost. Also, since most of the open markets use the number of downloads as a major indicator, the fact that a large number of downloads are leading to a rise in popularity and exposure to the game means that non-gamers It meets the needs of developers looking for a means.

However, there are two problems with this CPI approach. For example, in the case of smartphone games, users often download smartphone games in popularity. At this time, the popularity rank means that the number of downloads is counted and statistics are obtained. In fact, the user has not downloaded the game of his or her taste, and a large number of existing non-gamers are introduced through a mobile messenger such as KakaoTalk Actually, it was difficult to say that the taste of the gamers was actually reflected in the popularity rankings. Therefore, when the users did not match their taste after downloading the game, they did not use or delete the game.

In other words, conventionally, even if the CPI contents are downloaded by the user, since the abandonment rate is high, such as when the CPI contents are not used or deleted, there is a problem that the content distribution cost paid by the client and the actual content distribution effect are not compatible with each other . In addition, the distribution effect that the client can grasp was also based on the number of downloads of the content, which made it difficult for the client to grasp the effect of distributing his / her contents.

According to the present invention, the smart terminal of each user becomes a mother based on the NFC, and the content is distributed through the communication method between the users to provide the contents to the actual users, And provides a relationship spreading device and method for collecting and analyzing the client code including the client code, the NFC code, the user code, and the own code from each smart terminal and providing it to the client so that the client can grasp the correct distribution effect I want to.

Hereinafter, an embodiment of an NFC-based relational diffusion method and apparatus according to the present invention will be described with reference to the accompanying drawings.

1 is an exemplary diagram for explaining a concept of an NFC-based relational diffusion apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the NFC-based relational diffusion is based on a NFC (Near Field Communication) communication scheme, and each smart terminal of the user becomes a mother body, and peer to peer, R / W, (Cost Per Install) method in which contents are diffused to other users' smart terminals through communication between users including push, pull, and pull methods, and distribution costs are spread as much as they are. For the sake of convenience of explanation, the mobile terminal includes a mobile game (game app) mainly used as CPI advertisement contents. The relationship diffusion apparatus 10 will be described.

In the conventional CPI advertisement, even if the advertisement contents are manually distributed through the application store, mobile messenger, SMS, or the like, and the user actively installs the corresponding advertisement contents, the purpose of the CPI advertisement is not to use the contents but to compensate for the installation , But the above-mentioned advertisement spread advertisement has a problem that each individual person describes his / her advertisement contents to his or her own people, and person / individual person actively transmits and receives advertisement contents Because the offline delivery mode is used, users are more likely to continue to use advertising content such as mobile games. Therefore, the bounce rate for the corresponding advertisement content is lower than that of the conventional advertisement system, and accordingly, the advertisement cost paid by the advertiser 30 is compatible with the actual advertisement effect.

Meanwhile, the NFC-based relational diffusion apparatus 10 of the present invention seeks the advertisement contents (game apps, etc.) to the smart terminals of the first user 20, And collects information of users who have received the advertisement contents, and provides compensation (feedback) to the user for the situation or analyzes and mulls the collected information and transmits the result to the advertiser 30 So that the advertiser 30 can accurately grasp the advertisement effect on the content.

The NFC-based advertisement spreading apparatus 10 of the present invention will now be described in more detail. First, when a game company (advertiser) makes an advertisement request for a game app, the tag on server 100 of the present invention (NFC Data Exchange Format) 40 in order to spread the game app, which is a content, using the NFC communication method. That is, the advertisement contents are tagged so as to spread through NFC communication. At this time, the client code and the NFC code are generated so that the advertisement content to be distributed in the form of the NDEF message 40 and the advertiser 30 can be matched and managed. The NDEF message 40 used in the present invention will be described in detail with reference to FIG.

After the game application is converted into the NDEF message 40 as described above, the game application is tagged on to the smart terminal of the first user 20 in the advertisement agency (or the tag-on-server operating agency) The NDEF message 40 is seeded. The term seeding refers to the NDEF message 40 (advertisement content) being installed in the smart terminal of the first user 20, and the NDEF message 40 (advertisement content) And is a term used in the present invention.

For reference, the method of seeding the NDEF message 40 (advertisement contents) to the first user 20 is not limited to the NFC communication method, but may be performed through various methods using a wired / wireless communication network. That is, in the present invention, the reason why the advertisement contents are tagged on the NDEF message 40 is provided for the advertisement diffusion method between the individual and the individual, and the advertisement contents are not necessarily provided or provided only through the NFC communication method.

When the advertisement contents are installed in the smart terminal of the first user 20 as described above, a self code is generated, and a user code including the self code, the client code and the NFC code is generated. That is, the first user 20 has a client code, NFC code, and own code for the corresponding advertisement content. In this way, the secondary user who receives the advertisement content from the first user 20 also generates the user code. The user code includes the client code, the NFC code, the primary user code, and the own code. That is, the user code includes a client code, an NFC code, a line user code (a user who has provided advertisement contents to the user), and a self code. By using the user code, the history of the diffusion route of the advertisement contents can be grasped, and it is possible to grasp how much each user has transmitted the advertisement contents to the surrounding people.

When the advertisement contents are installed in the smart terminals of each user when the advertisement contents are spread through the communication between users as described above, the smart terminals of the user transmits the user codes to the tag-on server 100 via the communication network including the wireless LAN And the tag-on server 100 collects user information from the smart terminal of the user as described above, analyzes the user information, and provides the result to the advertiser 30 and the user.

Also, when transmitting the user information including the user code from the smart terminal of the user to the tag-on server 100, a feedback code may be transmitted along with the user information. The feedback code is the same as a reward code for a specific event according to a rule established through consultation with the advertiser 30. For example, when an event such as a case where the user delivers the advertisement content to the surrounding user a certain number of times occurs The feedback code corresponding to the event is transmitted to the server. Upon receiving the feedback code, the tag-on server 100 provides the user with the reward content corresponding to the event, either directly or through the advertisement client. As described above, the event occurrence condition and the compensation contents will be discussed in consultation with the advertiser 30.

That is, when the NFC-based advertisement spreading apparatus 10 tags the advertisement contents in the NDEF message 40 and sees the advertisement contents to the first user 20, the advertisement contents are diffused through communication between the users, The tag-on server 100 receives information (action log) including a client code, an NFC code, a pre-user code and a user code composed of the own code and a feedback code from the smart terminal installed with the advertisement contents, (Which may also provide the results of the analysis (advertising effects and statistical information)) and provide feedback content according to the received feedback code to the user.

FIG. 2 is an exemplary diagram illustrating an NDEF message format according to an exemplary embodiment of the present invention. Referring to FIG.

As shown in FIG. 2, the NFC-based advertisement spreading apparatus 10 of the present invention provides an advertisement content requested by an advertiser to a user in the form of an NDEF message 40, Since the NDEF message 40 transmitted at this time contains user information, the present invention uses two security methods to protect the user information.

First, when delivering advertisement contents from a device (smart terminal) to a device between users, a method of encrypting NDEF messages including advertisement contents is used. The NDEF message 40 used in the present invention is a new NDEF message type, and transmits a Device Smart Payload (DSP) record included in the NDEF message when the NDEF message is transmitted between trusted devices.

The encryption is AES (Advanced Encryption Standard) 128 bit encryption. The NDEF message 40 of the present invention includes an NDEF record (begin), an NDEF record, and an NDEF record (end), and the NDEF record includes at least one Encrypted DSP (Device Smart Payload) have. That is, the new type of NDEF message format of the present invention is the encryption of the DSP record containing the advertisement contents contained in the NDEF message 40. For reference, the DSP includes a payload type, a payload identifier, a device ID, and a payload.

Also, the related spreading device 10 of the present invention provides a user data security module 50 as another protection method for protecting user information. The user data security module 50 is installed in the smart terminal of the user and stores the malicious program such as malware or the malicious program such as tampering and interception, Protect information.

In addition, the NDEF record can record a large amount of payload through data compression, thereby allowing a relatively high capacity advertisement content to be converted into an NFC message format.

The member server 120 integrates and manages the information of the advertiser and the user. The user server 120 receives the user information including the user code from the smart terminal of the user when the advertisement is spread between the advertisers, Matches and manages user information. In addition, based on the information received from the user terminal, information including information such as a spreading route, a total spreading frequency, a spreading frequency and a diffusion date of each advertisement content is collected and managed.

The event server 130 provides compensation and feedback when a feedback code is received from the smart terminal of the user. When the user satisfies a specific event condition, a feedback code corresponding to the event is transmitted from the smart terminal of the user to the event server, and the event server transmits the feedback Provide users with compensation and feedback according to the code.

The DB server 140 stores and manages data of all the servers in the tag-on server 100, and is connected to the database 200. In addition, due to the characteristics of the advertisement spreading method of the present invention, the advertisement contents can be continuously spread, and thus the data received from the smart terminal of the user can not but accumulate continuously. The management of the data that continues to grow in this way is performed by the big data server 150. That is, the big data server minimizes the amount of data accumulated continuously and arranges, stores, and manages the data so that the user can easily grasp the data.

The web server 160 supports a manager web 161, a service web 162, and an advertiser web 163 as a web server providing a user interface in the tag-on server 100. The administrator web 161 is a kind of administrator tool, and an administrator can access the advertisement management server 161 to manage the entire advertisement promotion including the advertisement service start, termination, code generation, and advertisement log. In addition, the advertiser web 163 provides analysis and statistical information on the status of the advertisement and the advertisement effect to the advertiser. In addition, it is possible to transmit the data to be fed back to the user by collecting the results generated through the advertisement.
