Abstract

Provided is a method for protecting the copyright of a 3D printed object using a 3D barcode. A 3D printing method, according to one embodiment of the present invention, comprises generating a 3D barcode which contains particular information and is to be inserted in a 3D structure, and printing the 3D structure, wherein the 3D barcode is printed inside the 3D structure. As a result, when printing a 3D printed object by means of a 3D printer, the 3D barcode containing copyright information is also printed inside the 3D printed object, and thus forgery/falsification of information becomes practically impossible.

Description

3D 바코드를 이용한 3D 프린팅 출력물에 대한 저작권 보호 방법Copyright protection method for 3D printed output using 3D barcode
본 발명은 저작권 보호 기술에 관한 것으로, 더욱 상세하게는 3D 프린터를 이용하여 생성한 출력물에 대한 저작권 보호 방법 및 이를 위한 시스템에 관한 것이다.The present invention relates to a copyright protection technology, and more particularly, to a copyright protection method and a system therefor for an output generated using a 3D printer.
1980년대 최초 개발된 3D 프린터(3D Printer)는 현재 가정에서의 사용을 위한 보급형 모델까지 출시되고 있을 만큼, 그 활용과 범위가 가파른 증가 추세를 보이고 있다.The 3D printer, which was first developed in the 1980s, is showing a rapid increase in its use and scope as it is currently being released into a low-end model for home use.
이에, 3D 프린터를 활용한 다양한 조형물들이 등장하게 되었다. 인간의 손에 의해 창작된 조형물 외에도, 3D 프린터를 통해 제작된 이 조형물 역시 창작적인 요소를 갖기 때문에 저작물로서의 보호가 필요하다.Accordingly, various sculptures using 3D printers have emerged. In addition to the sculptures created by human hands, these sculptures created through 3D printers also have creative elements and require protection as copyrighted works.
최근 3D 프린터를 이용하여 만든 저작권이 있는 3차원 창작물에 대해서, 3D 스캐너에 의한 불법 복제가 쉽게 이루어지고 있는 실정임에도, 특별하게 제시된 대안은 없다.There is no specially proposed alternative to copyrighted three-dimensional creations made using a 3D printer, even though illegal copying by a 3D scanner is easily performed.
복제를 방지하는 것이 저작물 보호의 궁극적 수단이겠지만, 이에 앞서 진품의 저작물을 판별할 수 있도록 하는 수단이 전제되어야 한다. 그리고, 이 수단은 악의로 훼손될 수 없어야 한다.Preventing duplication may be the ultimate means of protecting the copyrighted work, but it must be premised on the means by which the copyrighted work can be identified. And this means must not be mutilated.

그리고, 센싱된 상기 3D 바코드의 형상으로부터 상기 특정 정보를 추출하는 단계;를 더 포함할 수 있다.The method may further include extracting the specific information from the shape of the sensed 3D barcode.
또한, 상기 3D 바코드에는, 정보를 나타내는 데이터가 1차원으로 수록될 수 있다.In addition, the data representing the information may be recorded in one dimension in the 3D barcode.
그리고, 상기 특정 정보는, 상기 3D 구조물의 저작권 정보일 수 있다.The specific information may be copyright information of the 3D structure.
또한, 상기 생성단계 및 상기 인쇄단계는, 3D 프린터에서 강제로 수행될 수 있다.In addition, the generating step and the printing step may be forcibly performed in the 3D printer.
한편, 본 발명의 다른 실시예에 따른, 3D 프린터 출력물은, 3D 프린터로 제작된 3D 구조물; 및 상기 3D 프린터에 의해 상기 3D 구조물 내부에 형성되며, 특정 정보를 수록하고 있는 3D 바코드;를 포함한다.On the other hand, according to another embodiment of the present invention, the 3D printer output, 3D structure made of a 3D printer; And a 3D barcode formed inside the 3D structure by the 3D printer and containing specific information.

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, with reference to the drawings will be described the present invention in more detail.
도 1은 3D 프린터를 이용하여 3D 출력물을 인쇄하는 상황을 나타낸 이미지이다. 본 발명의 실시예에 따른 3D 인쇄 방법에서는, 3D 프린터로 3D 출력물을 인쇄힐 때, 3D 출력물의 내부에 저작권 정보가 수록되어 있는 3D 바코드를 함께 인쇄한다.1 is an image showing a situation of printing a 3D output using a 3D printer. In the 3D printing method according to an embodiment of the present invention, when the 3D output is printed by the 3D printer, the 3D barcode containing copyright information is printed inside the 3D output.
도 2는 3D 프린터로 인쇄된 3D 출력물(100)의 내부에 3D 바코드(150)가 인쇄되어 있음을 개념적으로 나타낸 도면이다. 3D 바코드(150)에는 저작권 정보(제작자, 제작 일시, 제작 장소, 진품 인증 코드 등)가 수록되어 있다. 이 밖에도, 3D 바코드(150)에는 3D 출력물(100)에 대한 다른 정보, 이를 테면, 재질, 용도, 사용법, 가격 등이 더 포함될 수 있다.2 is a diagram conceptually showing that the 3D barcode 150 is printed inside the 3D output 100 printed by the 3D printer. The 3D barcode 150 contains copyright information (creator, production date, production location, genuine certification code, etc.). In addition, the 3D barcode 150 may further include other information about the 3D output 100, such as material, use, usage, price, and the like.
도 3은 3D 바코드의 구조에 대한 설명에 제공되는 도면이다. 3D 바코드(150)는 인쇄 영역과 비인쇄 영역(빈 영역)으로 "1"과 "0"을 나타낸다. 영역들 간의 간격은 1mm로 할 수 있는데, 다른 길이로 구현하는 것을 배제하지 않는다.3 is a view provided to explain the structure of the 3D barcode. The 3D barcode 150 represents "1" and "0" as the print area and the non-print area (blank area). The spacing between the regions can be 1 mm, which does not rule out other lengths.
도 4는 3D 바코드의 인식 방식의 설명에 제공되는 개념도이다. 도 4에 도시된 바와 같이, 테라헤르츠 파를 이용하여 직렬로 스캔함으로써, "1" 또는 "0"의 정보를 고속으로 인식할 수 있다.4 is a conceptual diagram provided for explaining a 3D barcode recognition method. As shown in FIG. 4, by scanning in series using a terahertz wave, information of "1" or "0" can be recognized at high speed.
3D 바코드에서 데이터를 1차원으로 수록하면, 다차원으로 구현하는 경우 보다 정보 인식을 매우 빠르게 취득할 수 있는 이점이 있다.When data is recorded in one dimension in a 3D barcode, there is an advantage in that information recognition can be obtained very quickly than in the case of multidimensional implementation.
도 5은 본 발명의 일 실시예에 따른 3D 인쇄 방법의 설명에 제공되는 흐름도이다.5 is a flowchart provided to explain a 3D printing method according to an embodiment of the present invention.
도 5에 도시된 바와 같이, 먼저, 인쇄하고자 하는 3D 구조물에 대한 3D 데이터를 획득하고(S210), 획득한 3D 데이터를 3D 프린터로 인쇄하는데 이용되는 3D 출력물 데이터로 변환한다(S220).As shown in FIG. 5, first, 3D data about a 3D structure to be printed is obtained (S210), and the obtained 3D data is converted into 3D output data used for printing with a 3D printer (S220).
S210단계에서, 3D 출력물(100)에 대한 3D 데이터는 저장매체 또는 통신 연결된 다른 디바이스나 네트워크 등을 통해 획득할 수 있다.In step S210, the 3D data for the 3D output 100 may be obtained through a storage medium or another device or network connected to the communication.
다음, 3D 출력물(100)에 대한 정보가 수록된 3D 바코드(150)를 생성한다(S230). 이후, 3D 출력물(100)을 인쇄하되, 3D 출력물(100)의 내부에는 3D 바코드(150)를 인쇄한다(S240). 즉, 도 1에 나타난 3D 출력물(100)의 인쇄 과정에서, 내부에는 3D 바코드(150)를 인쇄하는 것이다.Next, a 3D barcode 150 containing information about the 3D output 100 is generated (S230). Thereafter, the 3D output 100 is printed, but the 3D barcode 150 is printed inside the 3D output 100 (S240). That is, in the printing process of the 3D output 100 shown in FIG. 1, the 3D barcode 150 is printed inside.
도 6은 3D 출력물(100)의 내부에 인쇄된 3D 바코드(150)에 수록된 정보를 인식하는 3D 바코드 인식 장치를 도시한 도면이다. 이해와 설명의 편의를 위해, 도 3에서는 3D 출력물(100)과 3D 바코드(150)를 도시하였는데, 이들은 실제가 아닌 개념으로 나타내었다.FIG. 6 is a diagram illustrating a 3D barcode recognition device that recognizes information included in a 3D barcode 150 printed inside the 3D output 100. For the convenience of understanding and explanation, FIG. 3 shows the 3D output 100 and the 3D barcode 150, which are shown as concepts rather than actuals.
본 발명의 다른 실시예에 따른 3D 바코드 인식 장치는, 3D 출력물(100)을 파괴하지 않고 3D 바코드(150)를 스캔하여 그에 수록된 정보를 추출한다.The 3D barcode recognition apparatus according to another embodiment of the present invention scans the 3D barcode 150 and extracts information contained therein without destroying the 3D output 100.

이하에서는, 3D 바코드를 인식하는 과정에 대해, 도 7을 참조하여 상세히 설명한다. 도 7은 본 발명의 또 다른 실시예에 따른 3D 바코드 인식 방법의 설명에 제공되는 도면이다.Hereinafter, a process of recognizing a 3D barcode will be described in detail with reference to FIG. 7. 7 is a view provided to explain a 3D barcode recognition method according to another embodiment of the present invention.
도 7에 도시된 바와 같이, 먼저, 3D 바코드 인식 장치의 프로세서(310)는 신호 송신부(320)로 3D 출력물(100)의 하부 면을 스캔하면서 전자파를 송신하고, 이에 수신 센서(330)는 3D 바코드(150)에서 반사되는 전자파를 수신한다(S410).As shown in FIG. 7, first, the processor 310 of the 3D barcode recognition apparatus transmits electromagnetic waves while scanning the lower surface of the 3D output 100 to the signal transmitter 320, and the reception sensor 330 transmits 3D. The electromagnetic wave reflected from the barcode 150 is received (S410).
그러면, 영상화부(340)는 수신 센서(330)에 의한 수신결과를 합성하여, 3D 바코드(150)의 형상을 복원하고, 복원된 형상을 비트(0, 1) 단위로 분할한다(S420), Then, the imaging unit 340 synthesizes the reception result by the reception sensor 330, restores the shape of the 3D barcode 150, and divides the reconstructed shape in units of bits (0, 1) (S420).
다음, 프로세서(310)는 S420단계에서 비트 단위로 분할된 데이터를 결합하여 바코드 정보를 생성한다(S430). 그리고, 프로세서(310)는 S430단계에서 생성된 바코드 정보를 서버로 전송하여 해당하는 저작권 정보를 수신한다(S440).Next, the processor 310 generates barcode information by combining the data divided in bit units in step S420 (S430). Then, the processor 310 transmits the barcode information generated in step S430 to the server to receive the corresponding copyright information (S440).
다음, 프로세서(310)는 수신한 저작권 정보를 디스플레이(350)에 표시한다(S450).Next, the processor 310 displays the received copyright information on the display 350 (S450).
