Notarization platform server and its digital work notarization method {NOTARIZING PLATFORM SERVER AND METHOD FOR NOTARIZING DIGITAL WORK}

The present invention relates to a notarization platform server and a method of notarizing a digital work thereof, and more particularly, to a notarization platform server providing a notarization service of a copyright holder for a digital work, and a digital work notarization method thereof.

Recently, various digital contents are indiscriminately inundated on the Internet, and as these digital contents are modified and redistributed by an unspecified number of people even after distribution of the first copyright holder, the copyright of the original copyright holder is not protected.

Although copyright arises from the time of creation, there is a problem in that it is difficult to accurately specify when the copyright occurs in reality unless the work is registered.

In particular, digital contents are more likely to be infringed than any other work due to the capacity of the contents, the ease of delivery method, and the ease of technical transformation, and thus a countermeasure is required.

In this regard, the previous copyright committees and copyright associations protect works by uploading (registering) the contents of the entire work, such as digital files, program sources, and all contents works.

That is, by registering and storing the original data file itself, it aims to include the entire work and protect the copyright, and aims to protect the legal rights such as total or partial damage and infringement of the work.

In addition, depending on the amount of data, the registration cost is differentiated, and the entire work (digital files, program sources, content works, etc.) must be registered, and the server capacity is increased as the focus is on service operation in terms of management. The risk of the Copyright Committee for the management and management of the copyright data itself is also very high, and it is difficult to operate.

On the other hand, when it is publicly recognized that a digital content work existed in a certain form at least at a certain point in time, or that a certain type of file was transferred between users, it is easy to compare when the copyright occurred and the form of the original work. Thus, effective coping with infringement disputes is possible.

However, in order to obtain the above notarization, it is only possible to notarize the case by visiting a notarization office, or through a notary service agency, but there is a way to easily obtain notarization of digital works at a time that an individual wants. It is absent.

An embodiment of the present invention is to provide a notarization platform server that enables individuals to easily use the notarization service of a copyright holder for a digital work through an application installed in a user terminal, and a digital work notarization method thereof.

However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above technical problem, the digital work notarization method in the notarization platform server according to the first aspect of the present invention comprises the steps of: receiving information on the digital work selected by the user; Generating a hash data ledger for the digital work; Encrypting the generated hash data ledger; And storing the information on the encrypted hash data ledger, and decrypting the encrypted hash data ledger according to the request, and performing notarization of the copyright holder for the digital work.

In one embodiment, the step of generating a hash data ledger for the digital work may generate a hash data ledger for information on the digital work and information of a copyright holder corresponding to the digital work.

In an embodiment, the copyright holder information may include at least one of a name, a location area, a date of birth, a content creation date, a creation time, and main basic information and content information of a digital work defined by the copyright holder.

In one embodiment, the step of encrypting the generated hash data ledger may encrypt the generated hash data ledger based on a blockchain.

In one embodiment, the storing of the information of the encrypted hash data ledger may store information of the encrypted hash data ledger in the notarized platform server and the user's terminal.

The method for notarizing a digital work according to the present invention may further include inserting a notarization mark for the digital work as information of the hash data ledger is stored.

In one embodiment, the notarization mark may include information on the digital work and information of a copyright holder corresponding to the digital work.

In one embodiment, the step of notarizing the digital work includes decrypting the encrypted hash data ledger corresponding to the digital work as the digital work in which the notarization mark is inserted is uploaded to the notarization platform server. It is possible to perform notarization of the copyright holder for the digital work.

In one embodiment, the step of notarizing the digital work includes receiving the information of the digital work inputted through an application pre-installed in the user terminal, thereby generating an encrypted hash data ledger corresponding to the digital work. By decoding, the copyright holder for the digital work can be notarized.

In one embodiment, the step of performing notarization of the digital work is, when receiving information on the digital work scanned through a camera module by executing an application previously installed in the user terminal, encryption corresponding to the digital work The hash data ledger may be decrypted to perform notarization of the copyright holder for the digital work.

In addition, the notary platform server providing the notarization service of the copyright holder for the digital work according to the second aspect of the present invention includes a communication module for transmitting and receiving data to and from a user terminal, a memory storing a program for providing the notarized service, and the memory. It includes a processor for executing the stored program. At this time, as the processor executes the program, when receiving information on the digital work selected by the user through the communication module, it generates a hash data ledger for the digital work, and encrypts the generated hash data ledger. And decrypts the encrypted hash data ledger upon request, and performs notarization of the copyright holder for the digital work.

According to any one of the above-described problem solving means of the present invention, it is possible to notarize all digital works produced by individuals through an application installed in a user terminal.

In particular, as the application is widely used, public institutions such as police, prosecutors, and courts can certify the rights of copyright holders through notarization through a hash data ledger or notarized mark. It has the advantage of being able to use it as a material.

Hereinafter, a digital work notarization method performed in the notary platform server 100 according to an embodiment of the present invention will be described in more detail with reference to FIG. 3.

3 is a flowchart of a digital work notarization method according to an embodiment of the present invention.

In the method of notarizing a digital work in the notary platform server 100 according to an embodiment of the present invention, first, information on a digital work selected by a user is received (S110).

The user terminal 200 is pre-installed with an application distributed and linked from the notary platform server 100, and the user can select the digital content to be notarized after running the application, and the information of the selected digital content is the notarized platform. It is transmitted to the server 100.

Accordingly, the notary platform server 100 generates a hash data ledger for the digital work based on the information of the digital work (S120).

In one embodiment, the notarization platform server 100 may generate a hash data ledger for information on a digital work and information of a copyright holder corresponding to the digital work.

In this case, the information of the digital work may include hash information and I-Frame information of the content. In addition, the information of the copyright holder may include one or more of a name, a location area, a date of birth, a content creation date, a creation time, and main basic information and content information of a digital work defined by the copyright holder.

Next, the notary platform server 100 encrypts the generated hash data ledger (S130), and stores information on the encrypted hash data ledger (S140).

Then, according to a later request, the encrypted hash data ledger is decrypted to perform notarization of the copyright holder for the digital work (S150).

In this case, an embodiment of the present invention is characterized in that the hash data ledger is encrypted by applying a block chain technology and stored in a distributed storage and user terminal 200 to increase security for the origin of digital works.

In one embodiment, the blockchain technology applied to the present invention is, for example, IPFS (InterPlanetary), a distributed file storage technology for implementing Ethereum (ERC-20)-based smart contract technology (Solidity) and decentralized web (Web 3.0). File System), IPDB (InterPlanetary DataBase) technology, etc. can be applied.

Accordingly, the hash data ledger for the information of the digital work and the information of the copyright holder corresponding to the digital work is mutually stored in the distributed storage and the user terminal 200, respectively.

In one embodiment, information on the hash data ledger may be stored in the distributed storage. At this time, the hash data ledger may be generated when a user subscribes, encrypted with an encryption key stored in an application of each user terminal 200, and stored in a distributed storage. In addition, the blockchain address of the user created when the user subscribes to the smart contract of the blockchain service provider and the address of a distributed storage storing the encrypted hash data ledger information may be mapped and stored.

In this embodiment, information encrypted in the distributed storage can be checked only through an encryption key stored in the application of each user terminal 200.

That is, one embodiment of the present invention allows only the user's blockchain address to be stored in the general management server among the notary platform servers, and stores the information of the hash data ledger encrypted with the encryption key stored in the application of the user terminal 200. The address of the distributed storage can be saved and managed by mapping the address of the user's blockchain to the smart contract of the blockchain service provider.

In this case, the entity managing the notary platform server 100 can only check the block chain address of the hash data ledger, and it is impossible to check the contents stored in the distributed storage and the distributed storage unless a separate notarization request is made, and external hackers Even if they try to hack the blockchain, the address of the distributed storage can be known, but the stored contents are encrypted, so the encryption key cannot be known.Therefore, there is an advantage that it is impossible to deliberately modify or transform the information of digital works by the outside.

Meanwhile, according to an embodiment of the present invention, as the information of the hash data ledger is stored in the user terminal 200 and the distributed storage, a process of inserting a notarization mark for a digital work may be additionally performed.

In one embodiment, the notarization mark may include information on a digital work and information of a copyright holder corresponding to the digital work.

CERT" 마크를 디지털 저작물 파일 내에 수록함으로써, 향후 공증 서비스가 필요한 사안이 발생한 시점에 해당 공증 마크를 어플리케이션을 통하여 공증받을 수 있다.For example, "I" in the watermark format that contains information such as the copyright holder's name.

By including the "CERT" mark in the digital work file, the notarization mark can be notarized through the application at the time a matter requiring notarization service occurs in the future.

As an example, when a digital work in which a notarization mark is inserted is uploaded to the notarization platform server 100, the notarization platform server 100 acquires information on the digital work through the notarization mark, and an encrypted hash data ledger corresponding to the digital work It is possible to extract and decrypt, and perform notarization of the copyright holder for the digital work based on the decrypted information.

As another example, as information of a digital work inputted through an application preinstalled in the user terminal 200 is received, an encrypted hash data ledger corresponding to the digital work is extracted and decrypted, and based on the decrypted information, digital The copyright holder may notarize the work.

As another example, when receiving information on a digital work scanned through a camera module by executing an application preinstalled on the user terminal 200, the encrypted hash data ledger corresponding to the digital work is decrypted to Notarization of the copyright holder can be performed.

As described above, an embodiment of the present invention is a notarization mark through an application that provides a notarization service, or uploads a digital work itself containing a notarization mark that proves that the user directly inputs information on the digital work or is the creator of the first digital work. It is characterized in that it is possible to receive a notarization that the creator of the first digital work is correct by photographing and transmitting it to the notary platform server 100.

On the other hand, an embodiment of the present invention is characterized in that a hash data ledger is generated, encrypted, and stored based on the initial creation of a digital work to use a notarization service, but the subject of notarization is not necessarily limited to the first creation. .

That is, one embodiment of the present invention allows notarization of not only the original but also the modified version of the digital work, so that legal basis data for copyright infringement that may occur in the process of revising and redistributing the original digital work several times Can be used as.

To this end, in an embodiment of the present invention, after the hash data ledger for the initially created digital work is generated, when the original of the digital work is modified and distributed by the copyright holder, the original is generated for the modified digital work and its hash data. Numbering can be assigned as a standard so that the revision can be notarized.

At this time, the original and the revised are designated and managed in the form of a tree, so if notarization of a part of the original or revised is necessary in the future, the original or revised full or partial or part that needs to be confirmed can be easily searched, It is also possible to conduct the notarization process in batches.

Of course, this tree shape can be configured in various shapes such as a pyramid type or a multi-level hierarchical type, and this can be freely designated through an application according to the modification type of the copyright holder.

As described above, an embodiment of the present invention has the advantage of being able to receive notarization for the process of modification and redistribution of a digital work, so that in the event of a later dispute, more accurate legal protection can be obtained.

In the above description, steps S110 to S150 may be further divided into additional steps or combined into fewer steps, according to an embodiment of the present invention. In addition, some steps may be omitted as necessary, and the order between steps may be changed. In addition, even if other contents are omitted, the contents already described in FIGS. 1 to 2 are also applied to the digital work notarization method of FIG. 3.
