Description

Blockchain-based distributed data system and method for RCS provision {DISTRIBUTED DATA SYSTEM AND METHOD BASED ON BLOCK CHAIN FOR PROVIDING RICH COMMUNICATION SUITE}

The present invention relates to a blockchain-based distributed data system and method for providing RCS (Rich Communication Suite) services, and in particular, to a blockchain technology-based distributed data system and method for RCS content information authentication and security.

RCS (Rich Communication Suite) refers to an integrated communication service developed by global mobile carriers. RCS is a next-generation communication service capable of transmitting messages and multimedia without installing a separate application. Through the RCS platform, it is possible to provide various multimedia services such as group chat, high-quality video and image content transmission, as well as text transmission functions of existing SMS and MMS.

Considering the subject of development, convenience and expandability of the RCS platform, RCS is expected to continue to grow. Accordingly, it is expected that services such as transmission, transaction, approval, payment, etc. of more complex and various types of contents will be required in the future, as well as being able to replace the existing mass sending SMS and MMS services through the RCS platform.

For example, in the case of an RCS-based mobile advertisement service, unlike the existing mass sending SMS and MMS, the RCS platform can predict that it will be possible to provide a more complex advertisement sending service. Conventionally, if advertisement costs were simply measured according to the number of SMS and MMS transmissions, as in the charging processing method of the mobile advertising platform, charging according to the number of content transmission, charging according to the number of content clicks, and the type of action after clicking the content It can be predicted that complex transactions such as billing will be possible.

In addition, it is predicted that the amount and speed of data required for content transmission will vary depending on the capacity, quality, purpose, etc. of the content (eg, emoji, emoticon, etc.) transmitted through the RCS platform. Accordingly, when content is transmitted, the cost incurred depending on the amount and speed of data will also be complicated.

In addition, as the RCS platform is advanced and activated, the number of people or companies participating in the RCS ecosystem will increase. For example, as more participants such as advertisers, emoticon sellers, emoji sellers, content creators, etc. enter the RCS platform and the types of contents transmitted are diversified, the complexity of transactions is expected to increase. In this case, there may be a problem of lowering the reliability between participants for various transactions transmitted through the RCS platform.

Therefore, there is a need for a new type of system and method to make the transaction and authentication of complex and various contents exchanged through the RCS platform by all participants in the RCS ecosystem more fairly and transparently.

1 schematically shows a configuration of a distributed data system for integrated management of a Rich Communication Suite (RCS) according to an embodiment of the present invention. For example, FIG. 1 shows a distributed system 100 based on blockchain technology for RCS content information authentication and security.

Referring to FIG. 1, a distributed data system 100 based on blockchain technology for RCS content information authentication and security includes a CP (Contents Provider) 110, a mobile communication company 120, and other operators 150, Includes user 140 and the like. They can play a role as a major participant in the RCS ecosystem.

CP 110 is a content provider, and refers to all participants who produce, transmit, and sell content. For example, the CP 110 creates/generates content (for example, advertisement, emoticon, etc.) that it wants to promote or sell, such as an advertiser or emoticon maker, and registers it on the RCS platform, and through the RCS platform, the end customer It could be a person or company that wants to send it to the user. As shown in FIG. 1, one or more CPs 110-1, ..., 110-n may be included in the distributed data system 100 based on the blockchain technology.

The mobile communication company 120 is a major participant in the RCS platform, and is a participant who provides the basis for RCS service through its own Network Core system 122 and MMSC/SMSC server 124. According to an embodiment of the present invention, in the blockchain technology-based distributed data system 100 for RCS content information authentication and security, the mobile communication service provider 120 is a network core system 122 and an existing MMSC/SMSC server 124, etc. In addition to including the basic network configuration and platform necessary to provide the RCS service, it includes a separate RCS integrated management system 130 that can register/store/manage RCS contents as distributed data based on blockchain technology.

According to an embodiment of the present invention, the RCS integrated management system 130 includes an RCS AS 132, a CP content server 134, an RCS integrated management server 136, and a blockchain server 138. Each of the elements constituting the RCS integrated management system 130 may be physically configured in separate server devices, or may be software blocks configured in a single device.

The RCS AS 132 performs the same function as the existing RCS providing server. The CP content server 134 stores/manages content information registered by the CP 110. The RCS integrated management server 136 registers/manages the overall content information received from the RCS AS 132. In addition, the RCS integrated management server 136 performs overall management of billing information with increased transaction complexity, such as billing according to the number of content transmissions, billing according to the number of content clicks, and billing according to actions after content clicks, like a mobile advertising platform. can do. Blockchain server 138 collects all information on RCS content from RCS integrated management server 136, generates distributed data based on blockchain technology, and transmits it to participants (verification nodes) in the RCS ecosystem for validation. Request.

The user 140 is a customer who finally receives the content registered by the CP 110, and a user terminal that receives various information such as advertisements, emoticons, images, videos, and QR codes transmitted by the CP 110 through the RCS platform. May refer to.

The distributed data system 100 may include other communication companies 150 in addition to the mobile communication company 120 to which the CP 110 is connected. The other communication company 150 may be another mobile communication company to which it is linked, and may serve as a verification node of the distributed data system 100 based on blockchain technology.

FIG. 2 shows a signal flow of a distributed data system 100 based on blockchain technology for authentication and security when a transaction occurs through an RCS platform according to an embodiment of the present invention. 2, the authentication and security processing method when a transaction occurs through the RCS platform in the blockchain technology-based distributed data system 100 is a content pre-registration step (S201), a content information registration step (S203), and a registered delivery schedule. Arrival confirmation step (S205), content sending request step (S207), content information request step (S209), content information delivery step (S211), RCS sending request step (S213), content transmission step (S215), user action step ( S217), sending the action to the network (S219), sending the action to the CP content server (S221), sending the action to the RCS integrated management server (S223), creating an information package (S225), and transmitting the information package (S227) , Block creation step (S229), Block validation request step (S231), Block validation step (S233), validity determination step (S235), block chain linking step (S237), chain linking step (S239). have.

First, the CP 110 must pre-register the content desired to be transmitted to the CP content server 134 in the RCS integrated management system 130 of the mobile communication company 120 (S201). According to an embodiment of the present invention, the step of pre-registering content in the CP content server 134 and registering content information in the RCS integrated management server 136 is a block chain-based authentication and security of FIG. 3 as described below. The processing process can be further processed, and through this, more reliable content can be provided.

When the CP 110 registers the content in the CP content server 134, the CP content server 134 transmits and registers the content (S203). At this time, the registered content information may include one or more of information such as content content (eg, image, video, QR code, URL, etc.), content delivery date, delivery method, billing method, and target user. have.

When content registration is normally completed, the RCS integrated management server 136 checks whether the content delivery schedule registered by the CP 110 has been reached (S205).

The RCS integrated management server 136 requests the RCS AS 132 to send the content on the content delivery date set by the CP 110 (S207). For example, it is possible to instruct the user 140 to automatically send the content set by the CP 110 in the form of an RCS-based SMS or MMS according to a content transmission request.

When the RCS AS 132 receives the content transmission request, it first requests the CP content server 134 (S209), and receives the registered content from the CP content server 134 (S211).

The RCS AS 132 requests RCS transmission of the received content (S213), and the mobile communication company 120 transmits the received content to the user according to the existing RCS transmission process (S215).

After receiving the content through the RCS platform, the user 140 may take various actions (S217). Here, the user action according to an embodiment of the present invention may include various actions such as skipping, clicking, downloading, and purchasing the content after receiving user content.

The action of the user 140 is transferred back to the existing RCS sending networks 122 and 124 (S219), and transmitted to the RCS AS 132 through the existing RCS sending network process (S221).

Upon receiving the action of the user 140, the RCS AS 132 transmits the corresponding information to the RCS integrated management server 136 (S223).

After receiving the corresponding information, the RCS integrated management server 136 generates a single information package that can be generated as a block by combining the content information previously registered by the CP 110, user action information, and billing information (S225). ).

The RCS integrated management server 136 transmits the generated information package to the blockchain server 138 (S227).

The blockchain server 138 creates an information package containing all the content information delivered by the RCS integrated management server 136 as a new block using blockchain technology (S229).

After creating a new block, the block is transmitted to a participant in the RCS ecosystem to verify the validity of the block and requests verification (S231).

Here, all participants (verification nodes) in the RCS ecosystem refer to CP1(110-1) requesting content delivery, mobile communication company 120 used by CP1(110-1), mobile communication company used by CP 110 ( 150), another CPn (110-n), etc., and operates as a verification node for a distributed data system based on blockchain technology for authentication and security when a transaction occurs through the RCS platform. CP1(110-1), CP2(110-2),… , CPn (110-n), mobile communication company 120, other communication company 150, etc. each compare with the existing block chain and verify the validity of the block whether or not the transmitted block is a block with reliability (S233). At this time, validation can be done using the existing general blockchain verification method. For example, according to a blockchain-based consensus algorithm, verification can be performed by a method of proof-of-stake that compares the contents of the blocks owned by the verification nodes with the contents of the newly created block to determine whether the contents of the newly created block are valid. After completion of verification, CP1(110-1), CP2(110-2),… , CPn (110-n), mobile communication company 120, other communication company 150, etc. each transmits the verified validity result to the blockchain server 138.

The blockchain server 138 analyzes the received validation result and determines whether the valid result among all participants (verification nodes) is at least a preset level (eg, 70%) (S235). In this case, the preset threshold level may be set differently according to the required reliability.

When a normal response of more than a preset level (for example, 70%) is received, the blockchain server 138 additionally stores the corresponding block in its own blockchain to construct decentralized data. In addition, at the same time, another participant (verification node) is also requested to connect the block by transmitting the corresponding block (S237).

The other participants who received the block connection request store the received block in their storage space in a distributed data format to establish a chain connection (S239). Accordingly, a distributed data system based on blockchain technology for RCS content information authentication and security can be configured.

In addition, although not shown in the drawing, after the block-chain technology-based distributed data system is configured, transactions such as purchase and download according to the user's action and transactions such as billing and payment according to the user's action can be safely proceeded.

3 shows a signal flow of a distributed data system 100 based on blockchain technology for RCS content information authentication and security according to an embodiment of the present invention. For example, the process shown in FIG. 3 may be included in the content pre-registration step of FIG. 2 to verify validity based on blockchain technology for content information authentication and security. That is, when content is pre-registered from the CP 110 in the distributed data system 100 based on the blockchain technology according to an embodiment of the present invention, the processes of FIG. 3 to be described later may be included and executed.

3, the RCS content information authentication and security processing method in the blockchain technology-based distributed data system 100 includes a content registration request step (S301), a content information registration step (S303), and a content information package generation step (S305). , Information package transmission step (S307), Block creation step (S309), Block validation request step (S311), Block validation step (S313), validity determination step (S315), blockchain connection step (S317), chain connection It may include a step (S319), a block validation completion step (S321), a content registration request step (S323), a content registration step (S325), and a registered dispatch schedule reaching step (S327).

First, the CP 110 must pre-register the content desired to be transmitted to the CP content server 134 in the RCS integrated management system 130 of the mobile communication company 120 (S301).

When the CP 110 requests the CP content server 134 to register content, the CP content server 134 transmits the information to the RCS integrated management server 136 (S303). In this case, the content information requiring pre-registration may include one or more of information such as content content (eg, image, video, QR code, URL, etc.), content delivery date, delivery method, billing method, and target user.

The RCS integrated management server 136, which has received the content information from the CP content server 134, creates the content information as a package to verify the validity of the content, such as whether the content is harmful (S305), and blocks the generated information package. It is transmitted to the chain server 138 (S307). In this case, the content information package may include an image, text, transmission date, target information, etc. of the content registered by the CP 110.

The blockchain server 138 creates an information package containing all the content information delivered by the RCS integrated management server 136 as a new block by using the blockchain technology (S309). In addition, after creating a new block, the blockchain server 138 transmits a block to a participant in the RCS ecosystem to verify the validity of the block and requests verification (S311).

Here, all participants (verification nodes) in the RCS ecosystem refer to CP1(110-1) requesting content delivery, mobile communication company 120 used by CP1(110-1), mobile communication company used by CP 110 ( 150), another CPn (110-n), etc., and operates as a verification node of a distributed data system based on blockchain technology for RCS content information authentication and security. CP1(110-1), CP2(110-2),… , CPn (110-n), mobile communication company 120, other communication company 150, etc. each compare with the existing block chain and verify the validity of the block whether or not the transmitted block is a block with reliability (S313). At this time, validation can be done using the existing general blockchain verification method. For example, according to a blockchain-based consensus algorithm, verification can be performed by a method of proof-of-stake that compares the contents of the blocks owned by the verification nodes with the contents of the newly created block to determine whether the contents of the newly created block are valid. After completion of verification, CP1(110-1), CP2(110-2),… , CPn (110-n), mobile communication company 120, other communication company 150, etc. each transmits the verified validity result to the blockchain server 138.

The blockchain server 138 analyzes the received validation result and determines whether or not a normal response of more than a preset level (eg, 70%) among all participants (verification nodes) has been received (S315). In the case of a normal response of more than a preset level, the blockchain server 138 additionally stores the corresponding block in its own block chain to construct distributed data (S317). In this case, the preset threshold level may be set differently according to the required reliability.

In addition, at the same time, the blockchain server 138 transmits the corresponding block to other participants (verification nodes) to request the block to be connected, and stores the blocks received by other participants in their respective storage spaces in the form of distributed data ( S319). Accordingly, a distributed data system based on blockchain technology is formed for RCS content information authentication and security.

Accordingly, the block validity verification is completed (S321), the blockchain server 138 requests content registration to the RCS integrated management server 136 (S323), and the RCS integrated management server 136 finishes the content registration ( S325).

The RCS integrated management server 136 checks whether the content delivery schedule registered by the CP 110 is reached (S327), and after reaching the schedule, the steps after S207 according to FIG. 2 are further executed to make a transaction.

4 schematically illustrates a block chain network configuration diagram in which the block chain server 138 generates an RCS information package block and transmits it to a plurality of verification nodes according to an embodiment of the present invention.

Blockchain blocks are arranged by time, and the block contains transaction records and connection information for the previous block, making it difficult to forge and alter. In addition, it is possible to increase the transparency and reliability of transactions by adopting a distributed ledger structure.

As shown in FIG. 4, a block diagram is shown in which the block chain server 138 generates an information package received from the RCS integrated management server 136 as a block and transmits it to a participant in the RCS ecosystem, which is a verification node. Verification nodes can be added or reduced according to changes of participants in the RCS ecosystem.

At this time, instead of delivering blocks in one-to-one, one-way direction, all verification nodes are connected like a chain to form a blockchain network, and information is transmitted in both directions. Accordingly, it is possible to cross check for each verification node, thereby further increasing the reliability of the system.

The blockchain-based distributed data system and method for providing the RCS of the present invention is not limited to the above-described embodiment, and can be implemented with various modifications within the scope allowed by the technical idea of the present invention.
