본 발명은 QR(Quick Response) 코드에 관한 것으로, 더욱 상세하게는 보안을 강화하기 위해 홀로그램을 이용하여 QR 코드를 다시점으로 표출하는 신개념의 QR 코드에 관한 것이다.The present invention relates to a QR (Quick Response) code, and more particularly, to a new concept QR code that expresses a QR code in multiple views using a hologram to enhance security.
QR 코드는 흑백 격자무늬 패턴 코드로 정보를 나타내는 매트릭스 형식의 이차원 코드이다. 종래에 많이 쓰이던 바코드의 용량 제한을 극복하여 숫자 외에 문자 데이터까지 저장할 수 있다는 점에서 현재 널리 활용되고 있다.A QR code is a matrix-type two-dimensional code that represents information in a black and white plaid pattern code. It is currently widely used in that it can store character data in addition to numbers by overcoming the capacity limitation of barcodes that have been widely used in the past.
하지만, 도 1에 나타낸 바와 같이, QR 코드는 누구나 쉽게 복제할 수 있다는 문제가 있어, 보안이 필요한 분야에서는 사용하기에 부적합하다는 지적이 있어 왔다. 이에 따라, 보안을 강화한 QR 코드가 요구된다.However, as shown in FIG. 1, it has been pointed out that the QR code has a problem that anyone can easily copy it, and thus is unsuitable for use in areas requiring security. Accordingly, a QR code with enhanced security is required.
이를 위해서는, 일단 QR 코드의 복제가 어려워야 하고, 악의의 제3자가 QR 코드를 복제하였거나 획득하였다 하더라도, QR 코드에 수록되어 있는 정보를 확인할 수 없도록 해야 한다. To this end, it must be difficult to copy the QR code, and even if a malicious third party copies or acquires the QR code, it must be impossible to check the information contained in the QR code.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은, 기존의 2D QR 코드와 같이 쉽게 복제할 수 없는 홀로그램 QR 코드를 생성하고 스캔하는 방법을 제공함에 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a method of generating and scanning a hologram QR code that cannot be easily duplicated like a conventional 2D QR code.
상기 목적을 달성하기 위한 본 발명의 일 실시예에 따른, 홀로그램 QR 코드 기록 방법은, 홀로그램 QR 코드를 홀로그래픽 프린지 패턴으로 생성하는 단계; 및 생성된 홀로그래픽 프린지 패턴을 홀로그램 매질에 기록하는 단계;를 포함하고, 홀로그램 QR 코드는, 암호화된 정보를 수록한 제1 QR 코드; 및 암호화된 정보를 복호화 하기 위한 키가 수록된 제2 QR 코드를 포함한다.According to an embodiment of the present invention for achieving the above object, a holographic QR code recording method includes generating a holographic QR code as a holographic fringe pattern; and recording the generated holographic fringe pattern on a holographic medium, wherein the holographic QR code includes: a first QR code containing encrypted information; and a second QR code containing a key for decrypting the encrypted information.
제1 QR 코드와 제2 QR 코드는, 서로 다른 방향으로 표출되어, 서로 다른 시점에서 스캔 가능할 수 있다.The first QR code and the second QR code may be displayed in different directions and scannable at different viewpoints.
제1 QR 코드는, 다수의 QR 코드들로 구성되며, 다수의 QR 코드들에 수록된 암호화된 정보들을 복호화하여 연결하면, 복호화된 정보가 완성될 수 있다.The first QR code is composed of a plurality of QR codes, and decrypted information can be completed by decrypting and connecting encrypted information contained in the plurality of QR codes.
다수의 QR 코드들은, 서로 다른 방향으로 표출되어, 서로 다른 시점에서 스캔 가능할 수 있다.A plurality of QR codes may be displayed in different directions and scannable at different times.
홀로그램 QR 코드는, 홀로그램 기록 매질에서 홀로그램 QR 코드가 표출됨을 알려주기 위한 표지 이미지를 더 포함할 수 있다.The hologram QR code may further include a cover image for notifying that the hologram QR code is expressed in the hologram recording medium.
표지 이미지에는, 홀로그램 QR 코드를 스캔하는 방법을 안내하는 문구가 표시될 수 있다.In the cover image, a phrase guiding how to scan the hologram QR code may be displayed.
표지 이미지는, 제1 QR 코드 및 제2 QR 코드와 다른 방향으로 표출되어, 제1 QR 코드 및 제2 QR 코드와 다른 시점에서 스캔 가능할 수 있다.The cover image may be displayed in a direction different from that of the first QR code and the second QR code, and may be scannable at a viewpoint different from that of the first QR code and the second QR code.
한편, 본 발명의 다른 실시예에 따른, 홀로그램 QR 코드 스캔 방법은, 스마트 폰이, 홀로그램 매질에 기록된 홀로그램 QR 코드로부터 암호화된 정보를 수록한 제1 QR 코드를 스캔하는 단계; 스마트 폰이, 홀로그램 QR 코드로부터 암호화된 정보를 복호화 하기 위한 키가 수록된 제2 QR 코드를 스캔하는 단계; 및 스마트 폰이, 제2 QR 코드에 수록된 키를 이용하여, 제1 QR 코드에 수록된 암호화된 정보를 복호화하는 단계;를 포함한다.On the other hand, according to another embodiment of the present invention, a hologram QR code scanning method includes, by a smart phone, scanning a first QR code containing encrypted information from a hologram QR code recorded on a hologram medium; Scanning, by the smart phone, a second QR code containing a key for decoding encrypted information from the hologram QR code; and decrypting, by the smart phone, the encrypted information contained in the first QR code by using the key contained in the second QR code.
이상 설명한 바와 같이, 본 발명의 실시예들에 따르면, QR 코드를 홀로그램 기록 매질에 홀로그램으로 기록하여 표출/스캔함으로써, 기존의 2D QR 코드와 같이 쉽게 복제하는 것이 불가능해진다.As described above, according to the embodiments of the present invention, by recording a QR code as a hologram on a hologram recording medium and displaying/scanning it, it becomes impossible to easily copy like a conventional 2D QR code.
또한, 본 발명의 실시예들에 따르면, 홀로그램 QR 코드 내에 정보를 암호화하여 저장함으로써, QR 코드를 획득하였다 할지라도 복호화할 수 없어 보안을 강화할 수 있게 된다.In addition, according to the embodiments of the present invention, by encrypting and storing information in the hologram QR code, even if the QR code is obtained, it is impossible to decrypt it, so security can be strengthened.
아울러, 본 발명의 실시예들에 따르면, 복호화 키를 획득하였다 할지라도, 사용자 정보나 스마트 폰 정보를 이용한 이중 인증절차를 통해, 악의의 제3자에게 홀로그램 QR 코드에 수록된 정보가 노출되지 않게 된다.In addition, according to the embodiments of the present invention, even if the decryption key is obtained, the information contained in the hologram QR code is not exposed to a malicious third party through a two-factor authentication procedure using user information or smartphone information. .

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the drawings.
도 2는 본 발명의 실시예에 적용가능한 홀로그램 QR 코드의 설명에 제공되는 도면이다. 홀로그램 QR 코드는 QR 코드가 2D 이미지가 아닌 홀로그램으로 표시된다.2 is a diagram provided for explanation of a hologram QR code applicable to an embodiment of the present invention. In holographic QR code, the QR code is displayed as a hologram rather than a 2D image.
즉, 도시된 바와 같이, LED 광원을 통해 레퍼런스 광이 홀로그램 QR 코드가 기록되어 있는 홀로그램 기록 매질(100)로 입사되면, 서로 다른 시점에서, 1) 홀로그램 QR 코드 표지 이미지, 2) 복호화 키가 수록된 QR 코드 및 3) 암호화된 정보가 수록된 QR 코드를 관찰(사람의 경우)하거나 스캔(스마트 폰의 경우)할 수 있다.That is, as shown, when reference light is incident through the LED light source into the hologram recording medium 100 on which the hologram QR code is recorded, at different points in time, 1) a hologram QR code cover image, 2) a decryption key recorded QR codes and 3) QR codes containing encrypted information can be observed (in the case of a person) or scanned (in the case of a smartphone).
"1)"의 방향으로 표출되는(즉, "1)"의 시점에서 관찰/스캔되는) 홀로그램 QR 코드 표지 이미지는 QR 코드가 아닌 이미지이다. 이 이미지에는 홀로그램 기록 매질(100)에서 홀로그램 QR 코드가 표출됨을 알려주기 위한 이미지이다.The hologram QR code cover image expressed in the direction of “1)” (ie, observed/scanned from the viewpoint of “1)” is an image other than a QR code. This image is an image for notifying that the hologram QR code is expressed in the hologram recording medium 100.
1) 홀로그램 QR 코드 표지 이미지에는, 홀로그램 기록 매질(100)에서 표출되는 홀로그램 QR 코드를 스캔하는 방법을 안내하여 주는 문구가 표시될 수 있다. 이를 테면, "스마트 폰을 홀로그램 기록 매질(100)을 따라 움직여 감면서 QR 코드들을 스캔하세요."라는 문구가 표시되는 것이 가능하다.1) A phrase guiding how to scan the hologram QR code expressed in the hologram recording medium 100 may be displayed on the cover image of the hologram QR code. For example, it is possible to display the phrase "scan the QR codes while moving and winding the smart phone along the hologram recording medium 100."
"3)"의 방향으로 표출되는(즉, "1)"의 시점에서 관찰/스캔되는) QR 코드에는 암호화된 정보가 수록되어 있다. 정보가 암호화되어 있는 관계로, "3)"의 시점에서 관찰/스캔되는 QR 코드만으로는 정보를 획득할 수 없다.Encrypted information is recorded in the QR code that is expressed in the direction of “3)” (ie observed/scanned at the point of “1)”. Since the information is encrypted, the information cannot be obtained only with the QR code observed/scanned at the point of "3)".
"2)"의 방향으로 표출되는(즉, "2)"의 시점에서 관찰/스캔되는) QR 코드에는 복호화 키가 수록되어 있다. 이 복호화 키는 "3)"의 시점에서 관찰/스캔되는 QR 코드에 수록된 암호화된 정보를 복호화하는데 이용된다.A decryption key is included in the QR code that is expressed in the direction of "2)" (ie, observed/scanned at the point of "2)". This decryption key is used to decrypt the encrypted information contained in the QR code observed/scanned at the point of "3)".
이와 같이, 홀로그램 QR 코드에 기록된 1) 홀로그램 QR 코드 표지 이미지, 2) 복호화 키가 수록된 QR 코드 및 3) 암호화된 정보가 수록된 QR 코드는 서로 다른 방향으로 표출되어, 서로 다른 시점에서 관찰되며, 서로 다른 각도에서 스캔하여야 한다.In this way, the 1) hologram QR code cover image recorded in the hologram QR code, 2) the QR code containing the decryption key, and 3) the QR code containing the encrypted information are expressed in different directions and observed at different points of view, You need to scan from different angles.
한편, 인식률을 높이기 위한 방안으로, 도 3에 도시된 바와 같이, "1)"과 "2)" 사이에 2) 복호화 키가 수록된 QR 코드가 더 표출되도록 하고, "2)"와 "3)" 사이에 3) 암호화된 정보가 수록된 QR 코드가 더 표출되도록 구현하는 것이 가능하다.On the other hand, as a method for increasing the recognition rate, as shown in FIG. 3, a QR code containing a 2) decryption key is further displayed between “1)” and “2)”, and “2)” and “3) 3) It is possible to implement a QR code containing encrypted information to be further displayed.
도 4는 본 발명의 일 실시예에 따른 홀로그램 QR 코드 기록 시스템을 도시한 도면이다. 본 발명의 시예에 따른 홀로그램 QR 코드 기록 시스템은, 도시된 바와 같이, 홀로그램 생성 장치(210), 홀로그래픽 프린터(220) 및 광원(230)을 포함하여 구성된다.4 is a diagram illustrating a hologram QR code recording system according to an embodiment of the present invention. As shown, the hologram QR code recording system according to an embodiment of the present invention includes a hologram generating device 210, a holographic printer 220, and a light source 230.
홀로그램 생성 장치(210)는 도 1에 제시된 홀로그램 QR 코드를 홀로그래픽 프린지 패턴으로 생성한다. 홀로그래픽 프린터(220)는 홀로그램 생성부(210)에서 생성한 홀로그래픽 프린지 패턴을 홀로그램 기록 매질(100)에 기록한다. 광원(230)은 홀로그래픽 프린지 패턴 기록 과정에서 홀로그램 기록 매질(100)에 레퍼런스 빔을 인가한다.The hologram generating device 210 generates the holographic QR code shown in FIG. 1 as a holographic fringe pattern. The holographic printer 220 records the holographic fringe pattern generated by the hologram generator 210 on the hologram recording medium 100 . The light source 230 applies a reference beam to the hologram recording medium 100 during the holographic fringe pattern recording process.
이에 의해, 도 2에 도시된 바와 같은 홀로그램 QR 코드가 기록된 홀로그램 기록 매질(100)을 제작할 수 있게 된다.As a result, it is possible to manufacture the hologram recording medium 100 on which the hologram QR code as shown in FIG. 2 is recorded.
도 5는 본 발명의 다른 실시예에 따른 홀로그램 QR 코드 스캔 방법의 설명에 제공되는 도면이다.5 is a diagram provided to explain a hologram QR code scanning method according to another embodiment of the present invention.
홀로그램 QR 코드를 스캔하기 위해서는, 먼저, LED 광원(또는 레이저 다이어드 광원)으로 홀로그램 QR 코드가 기록된 홀로그램 기록 매질(100)에 레퍼런스 빔을 인가한다.To scan the hologram QR code, first, a reference beam is applied to the hologram recording medium 100 on which the hologram QR code is recorded using an LED light source (or laser diode light source).
그리고, 사용자는 스마트 폰에서 홀로그램 QR 코드 스캔 애플리케이션을 실행하고, 스마트 폰을 도 5에 도시된 화살표 방향으로 움직여 가면서, 1) 홀로그램 QR 코드 표지 이미지, 2) 복호화 키가 수록된 QR 코드 및 3) 암호화된 정보가 수록된 QR 코드를 차례로 스캔하여야 한다.Then, the user runs the hologram QR code scanning application on the smartphone and moves the smartphone in the direction of the arrow shown in FIG. You must scan the QR code containing the information in turn.
이 때, 1) 홀로그램 QR 코드 표지 이미지는 사용 안내를 위한 이미지이므로, 반드시 스캔할 필요는 없다.At this time, 1) Since the hologram QR code cover image is an image for use guidance, it is not necessary to scan it.
도 6은 본 발명의 다른 실시예에 따른 홀로그램 QR 코드 스캔 방법을 스마트폰(310)에서 실행되는 홀로그램 QR 코드 스캔 애플리케이션(320)의 관점에서 기술한다.6 describes a hologram QR code scanning method according to another embodiment of the present invention from the perspective of a hologram QR code scanning application 320 running on a smartphone 310.
도 5에 도시된 스캔 과정에 의해, 먼저, 1) 홀로그램 QR 코드 표지 이미지가 스캔되는데, 홀로그램 QR 코드 스캔 애플리케이션(320)은 이 이미지를 스마트폰(310)의 디스플레이에 표시하는 것 외에 다른 처리는 필요 없다.By the scanning process shown in FIG. 5, first, 1) the hologram QR code cover image is scanned, and the hologram QR code scanning application 320 displays this image on the display of the smartphone 310, and other processing is performed. Not required.
다음, 2) 복호화 키가 수록된 QR 코드가 스캔되면, 홀로그램 QR 코드 스캔 애플리케이션(320)은 스캔된 QR 코드에서 복호화 키를 획득한다.Next, 2) when the QR code containing the decryption key is scanned, the hologram QR code scanning application 320 obtains the decryption key from the scanned QR code.
그리고, 3) 암호화된 정보가 수록된 QR 코드가 스캔되면, 홀로그램 QR 코드 스캔 애플리케이션(320)은 스캔된 QR 코드에서 암호화된 정보를 획득하여 복호화 키로 복호화한다.And, 3) when the QR code containing the encrypted information is scanned, the hologram QR code scanning application 320 obtains the encrypted information from the scanned QR code and decrypts it with a decryption key.
한편, 보안을 더욱 강화할 필요가 있다면, 홀로그램 QR 코드 스캔 애플리케이션(320)이 사용자 정보 또는 스마트폰 정보를 기초로 암호 관리 서버(330)와 인증 절차를 거쳐야 복호화 키가 활성화 되도록 구현하는 것이 가능하다.On the other hand, if security needs to be further strengthened, the hologram QR code scan application 320 must go through an authentication procedure with the password management server 330 based on user information or smartphone information to activate the decryption key. It is possible to implement.
만약, 인증 절차를 통과하지 못하면, 복호화 키가 있어도 암호화된 정보를 복호화하지 못하게 되는 것이다.If the authentication procedure is not passed, the encrypted information cannot be decrypted even if the decryption key is present.
지금까지, 홀로그램 QR 코드의 구성과 이를 기록하고 스캔하는 방법에 대해 바람직한 실시예를 들어 상세히 설명하였다.So far, the configuration of the hologram QR code and the method of recording and scanning it have been described in detail with a preferred embodiment.
도 5에서는 스마트 폰을 위에서 아래로 움직이면서 홀로그램 QR 코드를 스캔하는 것을 상정하였으나, 스캔 방향은 문제되지 않는다. 즉, 스마트 폰을 아래에서 위로, 좌에서 우로, 또는 우에서 좌로 움직이면서 홀로그램 QR 코드를 스캔하는 경우에도 본 발명의 기술적 사상이 적용될 수 있다. 다만, 그에 맞게 홀로그램 QR 코드의 구성들의 표출 방향을 바꾸어 주는 것이 필요하다.In FIG. 5, it is assumed that the hologram QR code is scanned while moving the smartphone from top to bottom, but the scanning direction does not matter. That is, the technical idea of the present invention can be applied even when the hologram QR code is scanned while moving the smart phone from bottom to top, left to right, or right to left. However, it is necessary to change the direction of expression of the components of the hologram QR code accordingly.
한편, 암호화된 정보의 용량이 커서 하나의 QR 코드에 수록할 수 없는 경우에는 이를 다수의 QR 코드들에 나누어 수록할 수 있다. 암호화된 정보가 나누어 수록된 QR 코드들도 서로 다른 방향으로 표출/관찰되도록 홀로그램 QR 코드를 구성한다. 이 경우에는, 각 QR 코드들로부터 획득하여 복호화된 정보들을 연결하여 복호화된 정보를 완성하게 된다.On the other hand, if the capacity of encrypted information is large and cannot be recorded in one QR code, it can be divided into multiple QR codes and recorded. The hologram QR code is configured so that the QR codes containing the encrypted information are also expressed/observed in different directions. In this case, decrypted information is completed by connecting decrypted information acquired from each QR code.
한편, 본 실시예에 따른 장치와 방법의 기능을 수행하게 하는 컴퓨터 프로그램을 수록한 컴퓨터로 읽을 수 있는 기록매체에도 본 발명의 기술적 사상이 적용될 수 있음은 물론이다. 또한, 본 발명의 다양한 실시예에 따른 기술적 사상은 컴퓨터로 읽을 수 있는 기록매체에 기록된 컴퓨터로 읽을 수 있는 코드 형태로 구현될 수도 있다. 컴퓨터로 읽을 수 있는 기록매체는 컴퓨터에 의해 읽을 수 있고 데이터를 저장할 수 있는 어떤 데이터 저장 장치이더라도 가능하다. 예를 들어, 컴퓨터로 읽을 수 있는 기록매체는 ROM, RAM, CD-ROM, 자기 테이프, 플로피 디스크, 광디스크, 하드 디스크 드라이브, 등이 될 수 있음은 물론이다. 또한, 컴퓨터로 읽을 수 있는 기록매체에 저장된 컴퓨터로 읽을 수 있는 코드 또는 프로그램은 컴퓨터간에 연결된 네트워크를 통해 전송될 수도 있다.Meanwhile, it goes without saying that the technical spirit of the present invention can also be applied to a computer-readable recording medium containing a computer program for performing the functions of the apparatus and method according to the present embodiment. In addition, technical ideas according to various embodiments of the present invention may be implemented in the form of computer readable codes recorded on a computer readable recording medium. The computer-readable recording medium may be any data storage device that can be read by a computer and store data. For example, the computer-readable recording medium may be ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical disk, hard disk drive, and the like. In addition, computer readable codes or programs stored on a computer readable recording medium may be transmitted through a network connected between computers.
또한, 이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 설명하였지만, 본 발명은 상술한 특정의 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변형실시가 가능한 것은 물론이고, 이러한 변형실시들은 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해되어져서는 안될 것이다.In addition, although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications are possible by those skilled in the art, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
