Description

METHOD AND SYSTEM FOR PROVIDING USER DATA SELLING AND RESELLING SERVICE

The description below relates to a system and method for providing a service for selling and reselling user data, a sales service that sells user data to a buyer or subscriber, and a sales service that sells user data to another buyer or subscriber by the buyer or subscriber It's about technology that provides resale services.

With the development of mobile communication networks and mobile communication terminals, a mobile communication environment has been established, and research on marketing methods using this has been continuously conducted.

As a representative method among marketing methods in such a mobile communication environment, there is a method of providing a common advertisement to a plurality of users based on identification data of each of the plurality of users. In order to provide advertisements to a plurality of users as described above, identification data provided to devices of each of the plurality of users is required. Hereinafter, as identification data, a device ID given to the user's device, an advertisement ID provided by the OS of the user's device, an ID provided by a program running on the user's device, or a web program running on the user's device A cookie ID (eg, a cookie ID provided by an Internet browser running on a device) may be used.

As another method, there is a method of providing personalized advertisements to a plurality of users. To this end, the user's attribute data (eg, the attribute data is behavior pattern data that the user operates through the device - which web page the user's device has accessed, and what the user reads on the web page , information indicating which application is running on the user's device - and personal data indicating the user itself - information such as the user's age, gender, and residence, and other user's phone history, purchase information, credit information, self-driving Target advertisements suitable for users' interests should be provided in a timely manner by identifying personally identifiable or de-identified information that can be used for various marketing purposes. Similarly, in order to provide a target advertisement to each of a plurality of users, identification data assigned to a device of each of the plurality of users is required.

As an example of a method of providing targeted advertisements based on identification data and user attribute data, Korean Patent Registration No. 10-1369433 (registration date: February 25, 2014) encrypts information data of a user terminal in the form of an Internet cookie. A technology for providing a target advertisement service based on Internet cookie information is disclosed.

On the other hand, as a service in which a common advertisement is provided to each of a plurality of users based on the identification data and a service in which a target advertisement is provided to each of a plurality of users based on the identification data and the attribute data of the user as described above are popularized, a plurality of A service for selling user data including identification data of each of the users of .

For example, in a conventional service for selling user data, a seller provides identification data of each of a plurality of users to a buyer or a subscriber for a fee, so that the buyer or subscriber provides a common advertisement to each of the plurality of users. can provide In this case, the price paid by the buyer or the subscriber may be calculated according to the period for which the user data is to be used. Accordingly, the conventional service for selling user data has a problem in that a buyer or a subscriber is provided with identification data of each of a plurality of users, and then uses it without permission at all times beyond the contracted period.

As another example, as shown in FIG. 1 for explaining a conventional service for selling user data, the seller 110 selling user data transmits the identification data 120 of each of a plurality of users to the buyer or subscriber 130 . After receiving and providing a payment, when a specific user's attribute data confirmation is requested from the buyer or subscriber 130 , a specific user mapped to the specific user's identification data 121 among the plurality of users' respective attribute data 140 . The attribute data 141 of can be extracted and delivered to the buyer or subscriber 130 . Accordingly, the buyer or the subscriber 130 may provide a target advertisement to a specific user based on the attribute data 141 of the specific user. However, in the conventional service for selling user data, when the buyer or the subscriber 130 checks the attribute data 140 for all of the plurality of users, the attribute data of each of the plurality of users through the seller 110 There is no need to check 140 , and accordingly, there is a problem in that the buyer or the subscriber 130 may always use the user data without the need to pay any more to the seller 110 .

In this case, the user's identification data and attribute data are collected under the user's explicit or implicit consent. Also, even if the user's identification data and attribute data are collected, the user's identification data and attribute data cannot be used according to the user's request. Accordingly, since the conventional user data sales service does not pay any reward to the user, the user frequently requests not to use the identification data and attribute data, and there is a disadvantage in that it is difficult to collect it in the first place.

In addition, in the conventional service for selling user data, since only a seller who simply collects and builds user data can sell user data, a buyer or subscriber who purchases user data can simply use the user data, You will not be able to sell to other buyers or subscribers. Accordingly, the conventional service for selling user data has a disadvantage in that user data is limitedly sold.

FIG. 7 is a diagram for explaining a user database in the case where the use right and sales right are granted to buyers or subscribers in a method of providing a user data sale and resale service according to an embodiment, and FIG. It is a diagram for explaining a case in which identification data of each of a plurality of users is aperiodically changed according to an embodiment.

The server 200 according to an embodiment may include a computer-implemented user data sales and resale system. The server 200 sells and provides identification data of each of a plurality of users to a server or terminal of at least one first purchaser or subscriber who directly purchases user data, which is a client, from the server 200, , At least one primary buyer or subscriber server or terminal as a subject performing a user data sales and resale service providing method that grants the right to use and sales rights for identification data of each of a plurality of users to a server or terminal of at least any one A method of selling user data and providing a resale service may be performed through a web/mobile site connection related to a dedicated application installed on the server or terminal of the first purchaser or subscriber or the server 200 . That is, as shown in FIG. 5 , the user data sales and resale system (server 200 ) according to an embodiment directly provides at least one first purchaser or subscriber 510 to each of a plurality of users. At the same time as selling and providing identification data of at least one primary purchaser or subscriber 510 sells identification data of each of a plurality of users to at least one secondary purchaser or subscriber 520, and In order to provide this, the sales right, which is the sales right of each of the plurality of users, may be granted to at least one of the first purchasers or subscribers 510 .

Hereinafter, the right to use refers to the right to use the identification data of each of a plurality of users for a period of use corresponding to the price paid at the time of sale, and the right to sell refers to the right to use the identification data of each of the plurality of users in at least one second It means the right to sell to a car buyer or subscriber.

In addition, according to the user data sales and resale service providing method, the server 200 is at least any one of the servers or terminals of at least one primary buyer or subscriber who purchased or subscribed to the identification data of each of the plurality of users is another at least one In response to selling and providing identification data of each of the plurality of users to the server or terminal of the secondary purchaser or subscriber of The right to use and sale the identification data may be granted.

At this time, the server 200 provides information on at least one of the first purchasers or subscribers (eg, identification information of the server or terminal of at least one of the first purchasers or subscribers and at least one of the first purchasers) Or information on at least one second purchaser or subscriber different from the information on the license and sales right granted to the subscriber's server or terminal (for example, at least one second purchaser or subscriber's server or terminal By recording the identification information and at least one other information about the license granted to the server or terminal of the secondary buyer or subscriber) in the block chain, the identification data of each of a plurality of users is changed periodically or aperiodically. In this case, based on the information recorded in the block chain, the changed identification data of each of the plurality of users is adaptively provided to at least one first purchaser or subscriber and at least one second purchaser or subscriber different from that. can

The processor 220 of the server 200 includes a user database 310 and a user database 310 and It may include a user database manager 320 . Hereinafter, the user database 310 is described as a component of the processor 220 , but is not limited thereto and may be stored and maintained in the memory 210 of the server 200 . Depending on the embodiment, components of the processor 220 may be selectively included or excluded from the processor 220 . Also, according to an embodiment, the components of the processor 220 may be separated or merged to express the functions of the processor 220 . For example, at least some of the components of the processor 220 may be implemented in the memory 210 of the server 200 .

The processor 220 and the components of the processor 220 may control the server 200 to perform the steps S410 to S430 included in the method of providing a user data sale and resale service of FIG. 4 . For example, the processor 220 and components of the processor 220 may be implemented to execute instructions according to the code of the operating system included in the memory 210 and the code of at least one program.

Here, the components of the processor 220 may be expressions of different functions of the processor 220 performed by the processor 220 according to instructions provided by program codes stored in the server 200 . . For example, the user database manager 320 may be used as a functional representation of the processor 220 that controls the server 200 according to the above-described command so that the server 200 acquires and maintains the user database 310 . .

The processor 220 may read a necessary command from the memory 210 in which the command related to the control of the server 200 is loaded before the step S410 (not shown as a separate step in the drawing). In this case, the read command may include a command for controlling the processor 220 to execute steps S410 to S430 to be described later.

In step S410, the user database manager 320 may obtain and maintain the user database 310 in which identification data of each of the plurality of users is mapped to attribute data of each of the plurality of users. For example, the user database management unit 320 manages the identification data of each of the plurality of users and the attribute data of each of the plurality of users through a program running on the device of each of the plurality of users or the device of each of the plurality of users. By directly collecting, the user database 310 may be built and maintained by mapping the collected identification data of each of the plurality of users to the attribute data of each of the plurality of users. For another example, the user database management unit 320 receives identification data of each of a plurality of users and attribute data of each of the plurality of users collected from a server or terminal of a separate data collector, The user database 310 may be built and maintained by mapping the identification data to the attribute data of each of the plurality of users.

Here, the identification data of each of the plurality of users may be data arbitrarily assigned to simply distinguish and identify each of the plurality of users, regardless of data confirming the identity of each of the plurality of users. For example, the identification data of each of the plurality of users does not specify who each of the plurality of users is, but it is possible to simply distinguish and identify each of the plurality of users so as to provide advertisements to each of the plurality of users. can The identification data of each of the plurality of users includes a device ID of each of the plurality of users (eg, an ID provided by the OS of the device), an advertisement ID provided by the OS of each of the plurality of users, and a plurality of users. At least one of an ID provided by a program running on each device or a cookie ID provided by a web program running on each device of a plurality of users may be used. As a more specific example, as shown in FIG. 6 , the identification data 610 of each of the plurality of users may be a cookie ID provided by an Internet browser running in the device of each of the plurality of users.

In particular, the identification data 610 of each of the plurality of users is periodically or aperiodically by the processor 220 (user data sales and resale service providing system) included in the server 200 in step S430 to be described later. Since it can be changed, it can be a software ID that can be changed on each device of a plurality of users.

The attribute data of each of the plurality of users includes personal data representing each of the plurality of users or behavior pattern data of each of the plurality of users for a device of each of the plurality of users or a program running on the device of each of the plurality of users. At least one piece of data may be included. For example, the attribute data of each of the plurality of users may include personal data such as age, gender, residence, etc. of each of the plurality of users or the behavior of each of the plurality of users on a web page connected to the device of each of the plurality of users. It may include at least one data of pattern data (information indicating which web page the accessed web page is, which section is read by clicking on the web page, etc.).

Although not shown as a separate step, the user database manager 320 may perform a separate process in acquiring attribute data of each of the plurality of users. For example, in step S410 , the user database management unit 320 obtains identification data of each of the plurality of users and attribute data of each of the plurality of users, and then a plurality of users from the attribute data of each of the plurality of users De-identification processing may be performed on the attribute data of each of the plurality of users so that the identity of each of the users cannot be confirmed. Accordingly, the user database management unit 320 may acquire the user database 310 by mapping the identification data of each of the plurality of users to the attribute data of each of the plurality of de-identified users.

This de-identification process is intended to comply with laws related to user data collection and utilization, and since it is also illegal to collect and use data that can identify who a user is, the user database management unit 320 de-identifies In the process of directly collecting the identification data of each of the plurality of users and the attribute data of each of the plurality of users as well as the image processing, explicit or implicit user consent may be obtained from each of the plurality of users.

In addition, in the process of performing the de-identification process, the user database management unit 320 extracts valuable attribute data from among the attribute data of each of the plurality of users so that the target advertisement can be provided to each of the plurality of users. De-identification processing may be performed on attribute data of each of the plurality of users. At this time, extracting valuable attribute data among the attribute data of each of the plurality of users is to extract attribute data directly or indirectly related to the provision of the target advertisement to each of the plurality of users. It may mean "there is a possibility or higher than a reference value in the process of providing a target advertisement to each of a plurality of users".

For example, the user database management unit 320 collects the attribute data of each of the plurality of users, and then only the valuable attribute data 620 excluding the valueless attribute data as shown in FIG. 6 is the identification data 610 . It is possible to maintain the user database 310 by mapping to . Although the figure shows an example in which behavior pattern data is used as the attribute data 620 , the present invention is not limited thereto, and personal data may be used as the attribute data 620 .

In step S420, the user database management unit 320 sells identification data of each of a plurality of users to at least one first purchaser or subscriber in response to a price paid from at least one first purchaser or subscriber. and can provide

At this time, the price of the price paid from the at least one first purchaser or subscriber is the type of attribute data of each of the plurality of users mapped to the identification data of each of the plurality of users, the identification data of each of the plurality of users and/or based on the data amount of the attribute data. For example, as the data amount of identification data and/or attribute data of each of a plurality of users purchased or subscribed by at least one first purchaser or subscriber increases, the payment amount to be paid may become more expensive. In addition, the price of the consideration paid from the at least one first purchaser or subscriber may be determined based on the data value of the identification data and/or attribute data of each of the plurality of users. For example, in the process of providing the target advertisement, the more the identification data and attribute data that have higher availability than the reference value, the more expensive the payment amount may be. In addition, the price of the consideration paid from the at least one first purchaser or subscriber may be determined based on a request amount set by the user. Since the requested amount may be different for each user, the price at which the identification data of each of the plurality of users is sold to at least one first purchaser or subscriber is the sum of the requested amounts set differently by each of the plurality of users. can be determined by

Similarly, as at least one primary buyer or subscriber sells and provides identification data of each of a plurality of users to at least one secondary buyer or subscriber in step S430 to be described later, at least any other The price of the price paid from one secondary buyer or subscriber is the type of attribute data of each of the plurality of users mapped to the identification data of each of the plurality of users, identification data and/or attribute of each of the plurality of users It may be determined based on the data amount of data. In addition, the price of the consideration paid from at least one other secondary buyer or subscriber may be determined based on a data value of identification data and/or attribute data of each of the plurality of users. In addition, the price of the consideration paid from at least one other secondary buyer or subscriber may be determined based on a request amount set by the user. In particular, the price of the consideration paid from the at least one second purchaser or subscriber may be determined to be higher than the price of the consideration paid from the at least one first purchaser or subscriber. That is, in the process where the user database management unit 320 sells identification data of each of the plurality of users to at least one of the first purchasers or subscribers, at least one In the process of one primary buyer or subscriber selling identification data of each of a plurality of users to at least one secondary buyer or subscriber, the consideration paid from at least one other secondary buyer or subscriber The price may be higher. Accordingly, at least one second purchaser or subscriber is encouraged to purchase or subscribe to the identification data of each of the plurality of users sold by the user database management unit 320 rather than at least one first purchaser or subscriber. By allowing at least one first purchaser or subscriber to recover the loss of the price for purchasing or subscribing identification data of each of a plurality of users sold by the user database management unit 320 through resale, You can activate the sale of user data.

Here, the price paid from at least one first purchaser or subscriber and the price paid from at least one second purchaser or subscriber may be in the form of block chain-based electronic money.

In addition, in step S420, the user database manager 320 may pay at least a portion of the price paid from at least one of the first purchaser or subscriber as a reward to each of the plurality of users. At least a portion of the price paid as a reward to each of the plurality of users may be in the form of blockchain-based electronic money, but is not limited or limited thereto. In particular, at least a portion of the price paid as a reward to each of the plurality of users may be differentially paid to each user. For example, a larger amount of rewards may be paid to a user with a large amount of data sold among the plurality of users, and a smaller amount of rewards may be paid to a user with a small amount of data sold among the plurality of users.

In step S430 , the user database management unit 320 may grant at least one primary purchaser or subscriber a use right and a sales right for identification data of each of the plurality of users. Hereinafter, the user database management unit 320 grants at least one first purchaser or subscriber the right to use and sales rights for identification data of each of a plurality of users, a block chain related to data stored in the user database 310 It means to record the identification information of at least one first purchaser or subscriber and the information on the license and sales right granted to the at least one first purchaser or subscriber. For example, as shown in FIG. 7 , the user database management unit 320 includes at least any one of the identification information 710 and at least one of the first purchaser or subscriber in the block chain related to the data stored in the user database 310 . Information 720 of the period of use of the license granted to one first purchaser or subscriber and information 730 of the period of use of the sales right may be recorded.

Due to the characteristics of the block chain, at least one first purchaser or subscriber identification information 710 and at least one first purchaser or subscriber information on the license and sales right granted to the block chain 720, 630 It may be recorded by the user database management unit 320 as well as the server or terminal of at least one first purchaser or subscriber. The blockchain, which is changed as information is recorded, may be updated and transmitted to and shared with the user database management unit 320, at least one of the first purchaser or subscriber's server or terminal.

In addition, in step S430 , at least one of the first buyers or subscribers uses the sales right granted from the user database management unit 320 to transfer the identification data of each of the plurality of users to at least one of the second purchasers. Or you can sell and offer it to your subscribers. Accordingly, the user database management unit 320 at least one of the first purchaser or subscriber to the other at least one second purchaser or subscriber in response to the price paid from the other at least one second purchaser or subscriber As the identification data of each of the plurality of users is sold and provided, a right to use the identification data of each of the plurality of users may be granted to at least one other secondary purchaser or subscriber. Hereinafter, when the user database management unit 320 grants at least one second purchaser or subscriber the right to use and the right to sell the identification data of each of the plurality of users, the block related to the data stored in the user database 310 It means to record the identification information of at least one secondary purchaser or subscriber and information on the license granted to at least one secondary purchaser or subscriber in the chain. For example, as shown in FIG. 7 , the user database management unit 320 is different from the identification information 740 of at least any one secondary buyer or subscriber other in the block chain related to the data stored in the user database 310 . Information 750 of the period of use of the license granted to at least one secondary purchaser or subscriber, and at least any one of at least one that sold identification data of each of a plurality of users to at least one secondary purchaser or subscriber Identification information 710 of the first purchaser or subscriber of may be recorded.

Due to the nature of the block chain, at least one second purchaser or subscriber identification information 740 and other at least one second purchaser or subscriber information 750 about the license granted to the second purchaser or subscriber are recorded in the block chain. The subject may be the user database management unit 320 as well as the server or terminal of at least one other secondary purchaser or subscriber. The block chain that is changed as information is recorded is updated and the user database management unit 320, at least one server or terminal of the first buyer or subscriber, and at least one other server or terminal of the second purchaser or subscriber can be transmitted and shared.

In addition, in step S430 , at least one first purchaser or subscriber uses the sales right granted from the user database management unit 320 to transfer the identification data of each of the plurality of users to at least one second purchaser or According to the sale to the subscriber, at least a portion of the price paid from the second at least one second buyer or the subscriber may also be paid to the user database manager 320 . For example, an amount of 10% of the price paid from at least one second purchaser or subscriber to at least one primary purchaser or subscriber may be paid to the user database management unit 320 . In addition, at least a portion of the price paid from the second at least one second purchaser or subscriber may be paid as a reward to each of the plurality of users. For example, an amount of 10% of the price paid to at least one first purchaser or subscriber from at least one second purchaser or subscriber is paid to the user database management unit 320, and at the same time, at least another An amount of 10% of a price paid from one secondary buyer or subscriber to at least one primary buyer or subscriber may be paid to each of the plurality of users as a reward. For another example, an amount of 10% to 5% of the price paid to the user database management unit 320 out of the consideration paid to at least one first purchaser or subscriber from at least one second purchaser or subscriber Each of the plurality of users may be paid as a reward. As such, the rewards paid to each of the plurality of users may be different for each user. For example, a larger amount of rewards may be paid to a user with a large amount of data sold among the plurality of users, and a smaller amount of rewards may be paid to a user with a small amount of data sold among the plurality of users.

As such, the user database management unit 320 grants the sales right, which is the right to sell identification data of each of a plurality of users to at least one second purchaser or subscriber to at least one of the first purchasers or subscribers. At the same time, by receiving at least a portion of the consideration paid by at least one secondary buyer or subscriber to at least one primary buyer or subscriber, it is possible to activate the sale of user data and guarantee revenue. . In addition, in this way, the user database management unit 320 pays at least a portion of the profits obtained by selling user data as a reward to each of a plurality of users, thereby solving the disadvantage of low user consent for collecting and using user data. .

Also, in step S430 , the user database manager 320 may periodically or aperiodically change the identification data of each of the plurality of users. The user database management unit 320 not only periodically or aperiodically changes the identification data of each of the plurality of users, but also stores the change history related to the identification data of each of the plurality of users on the user database 310 . and can be maintained.

Hereinafter, periodically changing the identification data of each of the plurality of users means changing the identification data of each of the plurality of users according to a preset period, and aperiodically changing the identification data of each of the plurality of users This is an external request (eg, a user's request to prohibit data use and sale) or an internal request (a request that is automatically generated as the usage period of identification data of each of the plurality of users set by the user database management unit 320 expires) It means changing the identification data of each of the plurality of users in response.

Here, the user database management unit 320 may change the identification data of each of the plurality of users on the user database and at the same time change the identification data on the device of each of the plurality of users. Accordingly, by changing the identification data of each of the plurality of users in both the device of each of the plurality of users as well as the user database, advertisements may be transmitted based on the identification data of each of the plurality of users.

As an example of aperiodically changing the identification data of each of the plurality of users, in more detail, the user database management unit 320 sells the identification data of each of the plurality of users to at least one first purchaser or subscriber and If provided, at least one first purchaser or subscriber may be granted the right to use and sell the identification data of each of the plurality of users, and the use period of each of the use right and the sales right may be set. For example, as shown in FIG. 8 , when identification data 810 of each of a plurality of users is sold and provided to at least one of the first purchasers or subscribers 820, the user database management unit 320 ) may be recorded by setting information 830 of the period of use of the license granted to at least one of the first purchasers or subscribers and information 840 of the period of use of the sales right (the set period of use is for a plurality of users). Each of the identification data 810 may be adaptively adjusted according to the amount of the sale price, and the period of use of the right of use and the period of use of the right of sale are set to be the same). In addition, in response to at least one primary buyer or subscriber 820 selling and providing identification data 810 of each of a plurality of users to at least one secondary buyer or subscriber 850, The user database management unit 320 may set and record information 860 of the period of use of the granted license while granting a use right to at least one other secondary purchaser or subscriber 850 .

Accordingly, as the period of use of the license granted to at least one of the first purchasers or subscribers 820 and/or the period of use of the license granted to at least one of the second purchasers or subscribers 850 expires, , the user database management unit 320 is at least any one of the first purchaser or subscriber 820, the information 830 of the period of use of the license granted and / or at least any one of the second purchaser or subscriber (850) Based on the information 860 of the period of use of the license granted to at least one first purchaser or subscriber 820 and/or at least one second purchaser or subscriber 850 By checking the granted license and determining whether the period of use of each license is valid, the identification data 810 of each of the plurality of users is changed according to the determined result, and at least one first purchaser or subscriber The changed identification data 870 of each of the plurality of users may be provided to a person who has a valid usage period among the 820 or at least one of the second purchaser or subscriber 850 .

For a more specific example, the identification data 810 of each of the plurality of users is sold and provided to at least one first purchaser or subscriber 820 , and at least one of the first purchaser or subscriber 820 . The period of use of the license and the sales right is set to 6 months, and the identification data 810 of each of the plurality of users is at least one second purchaser or subscriber different from at least one first purchaser or subscriber 820 . When the period of use of the license of at least one of the second purchasers or subscribers 850 is set to 3 months as sold and provided as 850, the user database management unit 320 is the database management unit 320 at least 3 months from the present based on 3 months, which is the shortest period of use of any one of the first purchasers or subscribers 820, or at least one of the second purchasers or subscribers 850. At the same time changing the identification data 810 of each of the plurality of users on the user database at the last time and on the device of each of the plurality of user terminals to any new identification data 870, the right of use of the period of use set to the shortest period At least one first purchaser or subscriber 820 with a valid usage period except for at least one second purchaser or subscriber 850 with the changed identification data 870 of each of the plurality of users ), at least one primary purchaser or subscriber 820 may continue to utilize the identification data 870 of each of the plurality of users. On the other hand, since the other at least one secondary purchaser or subscriber 850 continues to hold the identification data 810 of each of the plurality of users before being changed, the device of each of the actual plurality of users Since it is different from the identification data 870 on the above, the identification data 810 of each of a plurality of users held by at least one secondary buyer or subscriber 850 in the server or terminal has no value, Even if attribute data of each of the plurality of users matching the identification data 810 of each of the plurality of users is maintained, the attribute data of each of the plurality of users is also of no value.

As such, the user database management unit 320 aperiodically changes the identification data 810 of each of the plurality of users, so that at least one first purchaser or subscriber 820 and/or at least one second The problem that the car buyer or subscriber 850 does not need to pay any more to the seller (server 200 ) is constantly using user data can be prevented.

As such, the identification data 810 of each of the plurality of users is sold to at least one of the first purchasers or subscribers 820, and the period of use of the granted license and/or at least any other second purchaser or subscriber The period of use of the license granted while being resold to 850 is at least one first purchaser and/or subscriber 820 or at least one second purchaser or subscriber 850 pays a predetermined price again. In this case, the period of use is reset so that at least one of the first purchasers and/or subscribers 820 or at least one of the second purchasers or subscribers 850 may continue to use user data.

Although not shown in a separate drawing, when a request to prohibit the use and sale of the user's user data is received from a specific user, the user database manager 320 may aperiodically change the identification data of each of the plurality of users. In this case, changing the identification data of each of the plurality of users aperiodically in response to the user data use and sale prohibition request means deleting the identification data of a specific user from among the identification data of each of the plurality of users ( That is, identification data of each of the users other than a specific user among the plurality of users may be maintained without any change).

In addition, although not shown in a separate drawing, as an example of periodically changing the identification data of each of a plurality of users, the user database management unit 320 periodically according to a preset period (eg, monthly, daily or hourly) to change the identification data of each of the plurality of users. As such, a period at which the identification data of each of the plurality of users is changed may be fixedly set, but the period is not limited or limited thereto, and the time may be changed and set according to the date. For example, on the first day, identification data of each of the plurality of users may be changed with a cycle of 12 hours, and on the second day, identification data of each of the plurality of users may be changed with a cycle of 6 hours. Therefore, the user database management unit 320 maintains the value of the attribute data of each of the plurality of users only for a period before the identification data of each of the plurality of users is changed, so that the user data is not paid for the user data even if it is not a purchaser or a subscriber. It can prevent unauthorized use by hacking that hacks the user database in order to use it without payment. In this case as well, the user database management unit 320 provides information on the period of use of the license granted to at least one of the first purchasers or subscribers and/or the license granted to at least any one of the second purchasers or subscribers). Confirm the license granted to at least one first purchaser or subscriber and/or the license granted to at least one second purchaser or subscriber based on the information on the period of use of By judging whether this is valid, as a result of the determination, at least one of the first purchasers or subscribers or at least one of the second purchasers or subscribers of the plurality of users changed to the person who has the right to use the valid period of use Identification data may be provided.
