Description

{Method and system for content managing on mobile service using block chain network}

The present invention relates to a content management method and system, and in particular, proposes a new method that can effectively manage and protect user-generated content on a mobile service using a blockchain network.

As the sale and purchase of goods through the Internet has become commonplace, in addition to large Internet shopping malls, small shopping malls operated by individuals are increasing, and the types of items sold are diversifying from clothing and various daily necessities to agricultural products and handmade accessories. there is.

Internet shopping malls help consumers to easily understand the characteristics of products and select products that fit their needs when purchasing products by providing pictures or videos of the products as well as documentary information to help them understand the products to be sold. In particular, recently, in addition to the product-related contents directly produced by the shopping mall operator, a third party directly uploads user-created contents (photos or videos) showing examples of use of the product to the shopping mall, allowing other consumers to enjoy more diverse information about the product. making it possible Such user-created content helps consumers to decide whether to purchase or not when selecting an item, so they can conduct wise consumption activities, and for shopping mall operators, it is helpful because it can serve as a publicity for the items to be sold. In order to promote such a positive shopping effect, the shopping mall operator may provide a predetermined price to users who create and provide content. This is the method of depositing money into the user's account. By receiving such a price, content creators have the advantage of obtaining economic benefits in addition to the satisfaction they enjoy as a model for the product. will contribute to

User-generated content uploaded to shopping malls, etc. has the characteristics of a work in itself as content in the form of photos or videos created with great care reflecting a special concept. Therefore, a device for personal protection such as publicity rights must be provided for user-created content, and copyright protection is required so that property values are not damaged. However, in Internet shopping malls through the web or mobile, sharing uploaded photos or videos through SNS is common, and in particular, it is easy to download or capture the content on the user's device. may be misused differently.

According to Patent Publication No. 10-2004-0102907, a technology for blocking multimedia content at the network level to prevent illegal distribution through the Internet has been proposed. Alternatively, filtering is performed on data transmitted from the system. Specifically, it analyzes a packet provided to and from the system, and extracts a watermark from this content if the packet is a content. Since the watermark contains information on distribution, it is used to determine whether the content is illegally distributed and whether to discard or transmit the content.

With the recent development of computing technology and the development of communication technology, all information is managed as digital information. Accordingly, concerns about information leakage are serious, and the need for security is emerging. In addition, as the spread of mobile devices expands, concerns about illegal copying and distribution of content on various platforms that perform mobile services are increasing. For example, when an action such as sharing on SNS or capturing on a portable personal device occurs without permission other than the consumer's normal use of content, it is impossible to completely protect user-created content uploaded to an Internet shopping mall, etc., and illegal distribution of user-created content As a result, legal disputes may increase, and as a result, there is a risk that the operation of an Internet shopping mall or users' voluntary content upload may be reduced.

In particular, in the case of a platform that provides various services through the Internet, in the process of considering platform operation and content protection at the same time, traffic of physical devices such as servers implementing the platform increases or the operating personnel must be excessively secured. difficulties arise throughout. Therefore, when operating a platform such as a shopping mall through the Internet network, more improved technology is required for maintaining the security of user-created content and protecting copyright, and a system capable of quickly and easily verifying the facts in case of a legal dispute is required.

The present invention was created under the above technical background, and an object of the present invention is to provide a method for content protection and management in a service platform through the Internet, in particular, a mobile service platform.

Another object of the present invention is to provide a method and system for quickly verifying and confirming the details when damage such as strict management and unauthorized copying occurs for protection of user-generated content.

Another object of the present invention is to provide a new method in which excessive traffic is prevented for content protection in a platform providing a mobile service, and content creators can easily check whether content is stolen or leaked.

In addition, other objects and technical features of the present invention will be presented in more detail in the following detailed description.

In order to achieve the above object, the present invention provides a platform operation unit that manages and controls information related to service operation, a content management unit that manages user-generated content, and a third user's confirmation, sharing, and capture of user-created content. In the central server comprising a behavior management unit for managing behavior details, a copyright management unit including a first management unit and a second management unit for managing data on the behavior details of user-created content, a platform produced by a user and operated by the central server The content management unit encrypts the content of photos or videos uploaded through data is processed and transmitted to the block chain network and the copyright management unit, the first management unit of the copyright management unit participates as a node in the block chain network to store a block of behavioral history related information, and the second management unit receives the information from the behavior management unit and storing behavioral history related data, wherein the content management unit encrypts user-generated content, the content including the ID of the user who created the content, the content data, and first time value information on the content upload time Metadata is encrypted, and the behavioral history-related information includes the content metadata, a third user ID, and a second time value related to the content use time of the third user. A mobile service content management method is provided.

In the present invention, it is preferable that the content encrypted by the content management unit is watermarked or DRM-processed so that a third user can check it only within the platform operated by the central server.

In the present invention, the user who created the content may receive the ID or data related to the content from the copyright management unit by inputting the user's ID or his/her content through the platform.

In the present invention, the first node that receives the data-processed behavior history-related information transmitted from the behavior management unit in the blockchain network is selected by a proof-of-stake or proof-of-work method, and is distributed from the first node to other nodes in a gossip manner. It is preferable to transmit

The present invention also provides a central server for managing a platform for providing mobile services, comprising: a platform operation unit that manages and controls information related to service operation; manages user-generated content; A content management unit for encrypting content metadata including the user's ID, the content data, and first time value information on the content upload time, and the third user's confirmation, sharing, capture, etc. behavior details for the user-created content A behavior management unit that processes and transmits information related to the behavior history to the blockchain network after confirming the behavior details that a third user confirms, shares, or captures encrypted content through the platform; A first management unit that manages the data on the behavior history, participates as a node in the block chain network to store a block of information related to the behavior history, and a second management unit that receives and stores the behavior information related information from the behavior management unit It includes a copyright management unit, and the information related to the action details includes the content metadata, a third user ID, and a second time value related to the content use time of the third user. It provides a mobile service content management system.

According to the present invention, user-created content uploaded to a service platform can be managed so that it is not leaked without permission, and when the content is illegally leaked, the distribution channel and the leaker can be easily checked. In particular, even when an unexpected problem in content management occurs, such as a service platform being hacked, related data can be secured through an external blockchain network, enabling copyright protection of user-created content.

In addition, in the content management method of the present invention, the user who uploaded the content to the service platform can easily check the behavior details of the third party related to the content recorded in the block chain without being patient with the node of the block chain network, so content creators other than the service platform operator It has the advantage of being able to take action for copyright protection together.

In addition, according to the content management method and system of the present invention, even if the content management unit or the copyright management unit in the platform is hacked, it is possible to check whether the content is illegally distributed by a third party or the content is forged or altered through the block chain network, and user-created content It can solve problems such as traffic concentration of the central server following management, and it is a block chain network with a slow processing speed by separating the verification of illegal content leakage into the primary verification process and the secondary verification in the block chain network in the management department in the platform, etc. It is possible to more effectively protect the copyright of user-created content while solving the shortcomings of

The present invention proposes a mobile service content management method and system using a blockchain network.

We manage to prevent unauthorized leakage of content such as photos produced by general users and uploaded to the platform, not content produced by the main body of the platform operation. It is possible to protect the copyright of user-created content by easily finding it and using it as a basis for legal action by securing data on the fact.

To this end, not only content management within the service providing platform, but also user-created content by managing content-related data and data on 'action history' such as checking, sharing, and capturing content through an external blockchain network. to prevent unauthorized leakage of The content management method and system of the present invention can be used more effectively to protect user-created content in a mobile service platform as well as a general web service platform that can be used with a personal computer.

1 is a schematic diagram illustrating a screen of a service platform 200 accessed through a mobile device, and shows a shopping mall output on the display of the mobile device (M). The mobile service platform may include items and procedures such as selection of a desired product, payment system, and delivery address input so that a plurality of products 210 can be displayed and the user can purchase the product through a procedure such as membership registration while checking the product. there is. In addition, the mobile service platform may display additional content to aid the user's understanding in relation to a specific product. ) can be displayed. Such user-generated content can be uploaded, for example, in the form of a photo or video file, other users can view the photo or video through the process of clicking on the content, and have the same effect as wearing a specific product yourself. This will help you make a product purchase decision. In addition, from the standpoint of the platform, it is possible to reduce the inconvenience and cost that the operating entity has to produce content for sale products on a daily basis, and to establish a mutually beneficial relationship by paying a predetermined price to the content creator.

In order for such user-generated content to be effectively used in the mobile service platform, to help the operation of shopping malls, etc., and to increase economic value, there is a clear and convenient process for encouraging and freely disclosing the content creatively. Systemic measures to prevent leakage are required.

For example, the main server implementing a platform (ex. Internet shopping mall) d where purchase activity of clothes, cosmetics, and other products occurs, and content sharing (or unwanted capture) such as uploaded photos occurs For copyright management, it is necessary to basically encrypt the content so that it is not leaked to the outside. In addition, it is necessary to secure a series of information on 'acts' related to product purchase, sharing or capture of product-related content, etc. in real time, and a method for storing and storing in reliable hardware and network so that it can be verified afterwards is required. .

In the present invention, as a key process for protecting user-generated content in a system implementing a mobile service platform, i) a method for encrypting (and decrypting) content, ii) purchasing a product, and sharing (or capturing) content related to the product A method of storing information related to actions, etc. based on a block chain, and iii) a method of identifying the leak path and leaker when an unwanted leak (distribution by capture, etc.) of the content occurs; The technical composition of the mobile service platform was differentiated to make it possible.

2 is a schematic diagram showing the configuration of a central server 100 for operating a mobile service. The central server basically includes a platform operation unit 110, a content management unit 120, a behavior management unit 130, and a copyright management unit 140. include

The platform operation unit 110 performs information management and control related to service operation in a platform that provides mobile services, for example, in the case of a shopping mall, functions such as product management, member management, delivery management, payment system management, etc. . When the platform is displayed on the user's mobile device, the screen composition may also be in charge of the platform operation unit.

The content management unit 120 manages the user-generated content, and encrypts the content metadata including the ID of the user who received the user-generated content and produced the content, the content data, and first time value information about the content upload time. do.

The behavior management unit (!30) manages behavior details such as confirmation, sharing, and capture of a third user for user-generated content. Here, the third user means a number of users who check or purchase products by accessing the mobile service platform other than the content creation user, and the confirmation, sharing, and capture of the contents is related to the specific product through the user's mobile device. Including acts of visually checking user-generated content (including clicking to enlarge the screen), sharing information related to the content on other SNS, etc., capturing the content (screen copying, etc.) do. The behavior management unit checks the 'behavioral history' that a third user confirms, shares, or captures the encrypted content through the platform, then processes the information related to the behavior history and delivers it to an external blockchain network.

The copyright management unit 140 manages data on behavioral details of user-created content, and includes a first management unit 142 and a second management unit 144 . The first management unit directly participates as a node in the block chain network and stores blocks of information related to behavior details. In addition, the second management unit receives and stores the information related to the behavior details from the behavior management unit in real time. In the present invention, while the copyright management unit periodically updates and stores information on the 'action history' of user-created content, users who are uploaded to the mobile service platform by participating directly as a node in an external blockchain network and storing the blocked data It is possible to sufficiently protect the copyright of the content by protecting the produced content thickly, preventing the leak of the content, and acquiring information related to the leak even if an unwanted leak occurs.

As described above, the user-created content encrypted through the content management unit can be visually checked only within the service platform, and the content itself can be shared externally or unauthorized capture can be prevented. In addition, the encrypted content through the content management unit may be delivered after being decrypted at the request of the content creator. 3 is a schematic diagram showing the encryption process of user-provided content. The content uploaded by the content creator (MC) to the platform may be encrypted, for example, using a symmetric encryption method, and the content is created after encryption with the platform's private key. If there is a user's request, the decryption process can be performed by delivering the private public key to the user.

The content encrypted in the content management unit may be watermarked or DRM (Digital Rights Management) processed so that a third user can check it only within the platform operated by the central server may be restricted. In addition, the user who created the content may receive the ID or data related to the content from the copyright management unit by inputting their ID or their content through the platform, which will be described later.

4 is a schematic diagram illustrating an interaction between a user's mobile device and a service platform. A service platform is implemented in a plurality of user mobile devices (M3) through the platform operation unit of the central server, and users' cyber shopping activities are performed on the mobile service platform. Separately, the content creator uploads his or her content through a mobile device (MC).

The content management unit 120 encrypts the content of the photo or video produced by the user and uploaded through the platform operated by the central server. In the encryption of user-generated content, the content management unit encrypts content metadata including the ID of the user who created the content, the content data, and first time value information on the content upload time. In the encrypted content, the behavior management unit 130 confirms the behavior details that the third user confirms, shares, or captures through the platform.

Behavioral history-related information is processed by the behavior management unit and delivered in real time to the external blockchain network (BN) and the copyright management unit. The first management unit 142 of the copyright management unit participates as a node in the block chain network to store a block of behavioral history-related information, and the second management unit stores behavioral history-related data from the behavioral management unit. The behavioral history-related information includes the content metadata, a third user ID, and a second time value related to the content use time of the third user, and includes data stored in the first management unit and the data stored in the first management unit in the copyright management unit. Data stored in the second management unit may be interlocked with each other through a time value.

The information related to the behavior history processed by the behavior management unit can use an external blockchain network, such as Ethereum, for reliability and stability of data storage. The disadvantage of the slow processing speed of the blockchain is the second supplemented by management. In other words, in terms of reliability that eliminates the risk of data manipulation, an external blockchain network is used as a secondary verification means, and in terms of data processing speed, the copyright management unit (second management unit) inside the platform is used as a primary verification method to mutually functionally complemented. In particular, it increases the utility of the blockchain network by directly participating in the first management department of the copyright management department as one of the nodes of the blockchain network. The first management unit may participate as a full node, for example, or as a light node if necessary.

On the other hand, the first node (N1, the first distributing node) that receives the data-processed behavioral-related information delivered from the behavior management unit within the blockchain network can be selected by a proof-of-stake method or a proof-of-work method, and from the first node to another node It can be distributed and transmitted in a gossip manner.

5 is a schematic diagram showing a process of encryption of user-generated content and related data transaction. A user uploads user-created content such as a photo or video through a mobile device (M), and the content is encrypted on the content management server. Encrypted files are transactional of behavior values in the behavior management server, and the contents are transmitted to the blockchain network. The dissemination of blocks takes the form of gossip in which the first distributing node propagates to an unspecified number of people. The propagated node then propagates to an unspecified number of nodes again. Information about content upload and creator is propagated and recorded to all nodes in the blockchain through the first 'distribution node'.

The first management unit of the copyright management unit stores a block of information related to 'action history' as one node included in the blockchain network. The second management unit receives and stores the 'action details' from the behavior management server. Even if the central server, especially the copyright management department is hacked, it can check whether the contents of the copyright management department are forged or altered during the secondary verification process (via the blockchain network) because the relevant data are kept in the blockchain network. In addition, by separately managing copyright-related verification of user-created content by the copyright management unit rather than focusing on the central server, traffic concentrated on the central server can be distributed.

6 is a schematic diagram illustrating a process of confirming behavioral history information of a content creator. Users who have created and uploaded content can enter their ID on the platform through the mobile device (M) and receive content-related information including the ID from the copyright management department. In addition, the user may input his/her own content and receive information such as action details related to the corresponding content from the copyright management unit. In this way, general users who are not included in the nodes of the blockchain network can easily find information related to their content recorded in the blockchain through the copyright management department. Accordingly, content creators can act as monitoring agents for protecting their own content copyright, and as a result, effective content protection is possible while reducing the burden on platform operators. In addition, it is also possible to execute fast 'primary verification' through the copyright management unit where the content-related data stored in the blockchain network is separately stored, rather than the only or final verification through the blockchain network, which has a slow processing speed.

The content protection and management method of the mobile service platform proposed in the present invention is not only an Internet shopping mall that sells clothes, but also a beauty related shopping mall such as cosmetics and skin health products. It can be used in shopping malls related to health products such as health care equipment, and furthermore, it is applied to online platforms that can be shared with third parties such as personal photos or video content to protect copyright and prevent leakage (management) of the content. and retrieval) are expected to be applicable.

Although the present invention has been exemplarily described through preferred embodiments above, the present invention is not limited to such specific embodiments, and various forms within the scope of the technical idea presented in the present invention, specifically, the claims may be modified, changed, or improved.
