Description

휴대폰을 이용한 보안인쇄물 진위식별기{INSPECTING DEVICE FOR SECURITY PRINTED MATTER USING MOBILE TELEPHONE} Security print authenticity identifier using mobile phone {INSPECTING DEVICE FOR SECURITY PRINTED MATTER USING MOBILE TELEPHONE}

본 발명은 휴대폰을 이용한 보안인쇄물 진위식별기에 관한 것으로, 보다 상세하게는 휴대폰의 카메라를 통해 보안코드를 촬영하여 다양한 인쇄물의 진위 여부를 누구나, 임의의 장소에서 간편하고 용이하게 판별할 수 있게 하는 휴대폰을 이용한 보안인쇄물 진위식별기에 관한 것이다.The present invention relates to a security print authenticity identifier using a mobile phone, and more particularly, a mobile phone that allows anyone to easily and easily determine the authenticity of various printed matters by photographing a security code through a camera of the mobile phone. The present invention relates to a security print authenticity identifier.

일반적으로, 지폐, 상품권, 신분증, 여권 등의 인쇄물에는 위조방지를 위해 보안코드가 인쇄된다. 보안코드는 통상 형광물질이 포함된 잉크로 특별한 색상/색감을 띄도록 인쇄되거나, 미세문자 또는 홀로그램 인쇄 등을 통해 다양한 형상을 갖도록 형성된다. In general, security codes are printed on printed matters such as banknotes, gift certificates, identification cards, and passports to prevent forgery. The security code is usually printed with an ink containing a fluorescent material to have a special color / color, or is formed to have a variety of shapes through fine characters or hologram printing.

이러한 보안코드를 식별하여 인쇄물의 진위 여부를 식별하기 위한 장치로서, 종래의 보안인쇄물 진위 식별기는 특정 주파수 영역의 빛을 발생시키는 램프(예를 들어 자외선 형광램프)가 조사한 빛을 반사판을 이용하여 반사하고, 반사판에 반사된 빛을 피검체에 투사하여 피검체에서 반사되어 나오는 빛을 판독하도록 구성되었 다. A device for identifying authenticity of printed matters by identifying such a security code, and a conventional security print authenticity identifier reflects light irradiated by a lamp (for example, an ultraviolet fluorescent lamp) that generates light in a specific frequency range by using a reflector. The light reflected by the reflector is projected onto the subject to read the light reflected from the subject.

그러나, 위와 같은 램프 및 반사판 등의 구성으로 인해, 장치가 불가피하게 커질 수밖에 없었다. 따라서, 지폐나 상품권이 통용되는 상점 등에서 보안인쇄물 진위 식별기를 구비하기 어려워 진위 식별기의 보급이 지연되고, 이로 인해 보안인쇄물의 위조범죄에 대한 대비가 효율적으로 이루어지지 못하는 문제가 있다. However, due to the configuration of the lamp and the reflector as described above, the device was inevitably large. Therefore, it is difficult to provide a security print authenticity identifier in a store where banknotes or gift certificates are commonly used, and thus the spread of the authenticity identifier is delayed, and thus, there is a problem in that preparation for counterfeit crimes of the security print cannot be efficiently performed.

한편, 갈수록 위조 기술이 발전함에 따라 보안코드를 인쇄하는 방식도 다변화되고 있는데, 종래의 보안인쇄물 진위식별기는 자외선 또는 특정 가시광 영역을 선택적으로 검출하는 방식에 특정되어 있어, 신규한 보안코드 인쇄방식이 적용된 화폐, 상품권 등의 다른 매체에 대해 호환적으로 이용될 수가 없었다. 이에 따라, 식별을 요하는 보안인쇄물의 종류에 따라 다수의 다양한 보안인쇄물 진위식별기가 필요하게 되어 진위식별기의 보급이 더욱 어렵게 되는 문제가 있다. Meanwhile, with the development of counterfeit technology, the method of printing security codes is also diversifying. The conventional security print authenticity identifier is specific to a method of selectively detecting ultraviolet rays or a specific visible region, and a new security code printing method is used. It could not be used interchangeably with other media, such as currency and gift certificates. Accordingly, a number of various security print authenticity identifiers are required according to the type of security print requiring identification, which makes it more difficult to spread the authenticity identifier.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 광범위하게 보급된 휴대폰의 카메라를 이용하여 인쇄물의 보안코드를 누구나 쉽고 간편하게 임의의 장소에서 판별할 수 있도록 한 보안인쇄물 진위식별기를 제공하는 것이다.The present invention is to solve the problems described above, an object of the present invention is to use a camera of a mobile phone widely distributed security printed authenticity identifier that anyone can easily and conveniently determine the security code at any place To provide.
