즉, 지문 인식은 확인 버튼을 터치하는 경우에 한번만 이루어지며, 보안 해제부(200)는 사용자가 입력한 키패드 입력 정보가 기등록한 비밀번호와 일치하고, 확인 버튼 터치 시 입력된 사용자의 지문 정보가 기등록한 지문 정보와 일치하는지 여부를 확인하여 보안을 해제하게 된다. That is, the fingerprint recognition is performed only once when the confirmation button is touched, and the security release unit 200 matches the keypad input information input by the user with a pre-registered password and the fingerprint information of the user input when the confirmation button is touched. The security is released by checking whether the fingerprint information matches the registered fingerprint information.
본 실시예에 따를 경우에는, 키패드 입력 시마다 지문 인식을 매번 수행하지 아니하여도 되어, 전체적인 연산량이 감소되는 장점이 있다. According to the present exemplary embodiment, the fingerprint recognition may not be performed every time the keypad is input, thereby reducing the overall amount of computation.
또한, 별도의 지문 인식 센서를 화면 하단의 베젤 또는 스마트폰 본체의 배면 등에 구비하지 아니하고도, 화면영역의 지문 인식을 확인 버튼 입력 시 수행하여, 사용자 지문 정보를 이용한 인증 수행이 가능한 효과가 있다.In addition, even without having a separate fingerprint recognition sensor on the bottom of the bezel or the bottom of the smartphone body, the fingerprint recognition of the screen area is performed at the time of input of the confirmation button, it is possible to perform authentication using the user fingerprint information.
도 5는 본 발명의 실시예에 따른 지문 인식 및 패턴 인식을 연동한 이중 보안 장치의 실시예를 나타내는 도면이다. 5 is a diagram illustrating an embodiment of a dual security device interlocking fingerprint recognition and pattern recognition according to an embodiment of the present invention.
본 실시예에 따르면, 인식부(100)는 터치 스크린 상에 격자 형상으로 도시된 패턴 포인트에 대하여, 사용자가 그리는 패턴을 인식하게 된다. According to the present exemplary embodiment, the recognition unit 100 recognizes a pattern drawn by a user with respect to a pattern point shown in a grid shape on the touch screen.
이 때, 인식부(100)는 각 패턴 포인트에서 지문 인식을 수행하고, 사용자의 패턴 입력이 완료되면, 보안 해제부(200)는 패턴 입력 정보 및 지문 인식 정보가 기등록된 패턴 및 지문 정보와 일치하는 경우 보안을 해제한다. At this time, the recognition unit 100 performs a fingerprint recognition at each pattern point, and when the user's pattern input is completed, the security release unit 200 and the pattern input information and the fingerprint information and the fingerprint information and the pre-registered pattern and fingerprint information; If it matches, turn off security.
인식부(100)는 기설정된 패턴 포인트에서 지문 인식을 수행하는 것이 가능하여, 도 5에 도시한 바와 같이 패턴이 지나는 각 패턴 포인트에서 모두 지문 인식을 수행하거나, 시작 및 최종 패턴 포인트에서만 지문 인식을 수행하는 등 다양하게 변형하여 적용함이 가능하다. The recognition unit 100 may perform fingerprint recognition at a predetermined pattern point. As shown in FIG. 5, fingerprint recognition may be performed at each pattern point through which the pattern passes, or fingerprint recognition may be performed only at the start and final pattern points. It is possible to apply various modifications such as performing.
본 발명의 실시예에 따르면, 감지 패턴을 이용하여 사용자의 패턴 입력 시 그 사용자의 지문 정보를 동시에 인식하여, 감지 패턴 및 지문 인식을 통하여 이중 보안을 제공하는 효과가 있다. According to an exemplary embodiment of the present invention, when a user inputs a pattern using a detection pattern, the fingerprint information of the user is simultaneously recognized, thereby providing dual security through the detection pattern and the fingerprint recognition.
도 6은 본 발명의 실시예에 따른 지문인식 영역을 이용한 애플리케이션 보안 방식을 나타내는 예시도이다. 6 is an exemplary view showing an application security method using a fingerprint recognition area according to an embodiment of the present invention.
본 실시예에 따르면, 터치 스크린의 전체 화면에 대하여 지문인식을 수행하지 아니하고, 기설정된 구획 영역에서만 지문 인식 센서를 구성하거나 지문 인식 영역으로 설정하여 제공한다. According to the present exemplary embodiment, the fingerprint recognition sensor may be configured or provided as a fingerprint recognition area only in a predetermined partition area without performing fingerprint recognition on the entire screen of the touch screen.
즉, 도 6의 (a)에 도시한 바와 같이, 전체 화면 중 특정 영역에 대하여 투명 지문인식을 수행하여, 해당 영역에서만 지문 인식이 동작되도록 설정한다. That is, as shown in (a) of FIG. 6, transparent fingerprint recognition is performed on a specific area of the entire screen, and the fingerprint recognition is set to operate only in the corresponding area.
도 6의 (b)에 도시한 바와 같이, 사용자가 원하는 폴더 또는 애플리케이션을 지문인식 영역으로 드래그하여 그 아이콘을 배치하면, 스마트폰 전체에 대한 보안이 해제된 경우라 하더라도, 지문 인식 영역에 존재하는 애플리케이션은 사용자의 지문 인식을 통한 인증 절차가 완료된 후에만 그 구동이 가능하게 된다. As shown in (b) of FIG. 6, when a user drags a desired folder or application to the fingerprint recognition area and places the icon, even if the security of the entire smartphone is released, the user may be present in the fingerprint recognition area. The application can be run only after the authentication process through the user's fingerprint recognition is completed.
도 6의 (b) 및 (c)에 도시한 바와 같이, "이메일" 애플리케이션을 지문인식 영역에 배치하게 되면, 스마트폰에 대한 잠금이 해제된 경우라도 하더라도, 이러한 "이메일" 애플리케이션 수행을 위하여는 아이콘 터치 시 인가되는 사용자 지문에 대한 인증을 수행하여, 애플리케이션 자체에도 보안을 설정할 수 있는 효과가 있다. As shown in (b) and (c) of FIG. 6, when the "e-mail" application is placed in the fingerprint recognition area, even if the lock on the smartphone is released, the "e-mail" application may be executed. By authenticating the user fingerprint applied when the icon is touched, there is an effect that security can be set in the application itself.
지문인식 영역은 그 설계에 따라 화면의 어느 특정 영역에 배치할 것인지가 결정될 수 있고, 사용자는 여러 개의 홈 화면을 통하여, 각 화면에서의 지문인식 영역에 지문인식을 통한 보안이 설정된 폴더 또는 애플리케이션을 복수 개 배치하는 것이 가능하다.

It is possible to set the user authentication to be performed.
도 7은 본 발명의 실시예에 따른 감지 패턴을 나타내는 예시도이다. 7 is an exemplary view illustrating a sensing pattern according to an embodiment of the present invention.
본 발명의 실시예에 따른 감지 패턴(300)은 투명 패널을 구성하는 커버 글래스의 배면에 배치되어, 발생되는 정전용량 값을 순차적으로 읽어 들이는 센서 구조이다. The sensing pattern 300 according to the exemplary embodiment of the present invention is disposed on the rear surface of the cover glass constituting the transparent panel, and sequentially reads the generated capacitance value.
감지 패턴(300)은 투명 박막으로, 종, 횡축 연결선 및 게이트 절연체가 투명하게 구성된 박막형 트랜지스터 회로로 구성되며, 유도된 정전 용량 변화값을 순차적으로 전달하는 것을 특징으로 한다. The sensing pattern 300 is a transparent thin film, and is composed of a thin film transistor circuit in which vertical, horizontal connecting lines, and gate insulators are transparent, and sequentially transmits an induced capacitance change value.
정전 용량식 지문인식 터치 센서는 센서 내부에 미세한 구조의 캐패시터를 다수 구성함으로써, 지문의 미세 굴곡으로 인한 정전 용량의 변화를 인식하는 방법을 채택하고 있는데, 소재 및 회로를 포함한 기술적 한계로 인하여 불투명하고 극소 정전용량 변화에 대한 탐지가 어려워 미세한 지문 인식이 어려운 실정이다. The capacitive fingerprint touch sensor adopts a method of recognizing a change in capacitance caused by fine bending of a fingerprint by constituting a large number of capacitors with a fine structure inside the sensor, which is opaque due to technical limitations including materials and circuits. It is difficult to detect minute fingerprints because it is difficult to detect microcapacitance changes.
본 발명에 따르면, 전술한 구조를 통하여 500 pppi이상의 고해상도 정전식 센서 모듈을 구현하는 것이 가능하며, 감지 면적 및 둘레를 증가시켜 신호 감도를 향상시킴으로써, 투명 재질의 특성상 높은 저항으로 인하여 발생되는 신호 딜레이에 관한 문제점, 증착의 어려움에 대한 문제점을 함께 해결하는 것이 가능하다. According to the present invention, it is possible to implement a high-resolution capacitive sensor module of 500 pppi or more through the above-described structure, and by increasing the detection area and circumference to improve the signal sensitivity, the signal delay caused by the high resistance due to the characteristics of the transparent material It is possible to solve the problem with respect to the problem of, the difficulty of deposition.
도 7은 본 발명의 실시예에 감지 패턴을 나타내는 개념도로써, 감지 패턴(300)은 지문 굴곡보다 미세한 간격으로 기설정된 간격에 따라 설치되고, 주변의 감지 패턴과 커플링(300a, 300b)되어 감지 면적 및 감지 둘레가 확장되는 것을 특징으로 한다. FIG. 7 is a conceptual diagram illustrating a sensing pattern in an embodiment of the present invention. The sensing pattern 300 is installed at a predetermined interval at a smaller interval than fingerprint bending, and is coupled to the surrounding sensing patterns 300a and 300b to detect the sensing pattern. It is characterized in that the area and the sensing circumference is extended.
즉, 도 7의 (b)에 도시한 바와 같이, 커플링을 통하여 감지 면적 및 둘레의 길이가 증가되므로, 신호 감도가 높아지는 효과가 있다. That is, as shown in FIG. 7B, since the sensing area and the length of the circumference are increased through the coupling, the signal sensitivity is increased.
다시 말하면, 감지 패턴의 면적은 미세 간격으로 설정된 x축, y축 선에 의하여, 그 면적 증가에 있어 한계가 있는 바, 감지 패턴의 커플링을 통하여 감지 면적 및 둘레를 증가시켜 높은 신호 감도로 정전 용량을 유도하는 것이 가능하다. In other words, the area of the sensing pattern is limited by the x-axis and y-axis lines set at fine intervals, and the area of the sensing pattern is limited. The sensing area and the circumference are increased through the coupling of the sensing pattern, and thus the electrostatic force is detected at high signal sensitivity. It is possible to derive the dose.
또한, 커플링(300a, 300b)된 감지 패턴에 연결된 1개의 y 축 선으로 각각의 패턴을 교차식으로 on/off제어하여, 제어부와 감지 패턴 사이를 연결하는 전체 연결 선의 수(x축, y축 선)를 절반으로 줄이는 효과가 있다.In addition, the number of connecting lines (x-axis, y) connected between the control unit and the sensing pattern by controlling each pattern on / off alternately with one y-axis line connected to the sensing patterns coupled to the coupling 300a and 300b. It has the effect of reducing the axis by half.
커플링된 감지패턴 300a 및 300b는 기설정된 방식에 따라 교차식으로 온/오프 되며, 기설정된 방식은 문턱(threshold) 전압값, 문턱(threshold) 주파수 값 등 다양한 방식으로 구현됨이 가능하다. The coupled sensing patterns 300a and 300b are alternately turned on / off according to a preset method, and the preset method may be implemented in various ways such as a threshold voltage value and a threshold frequency value.
본 발명의 추가적인 실시예에 따른 감지 패턴(300)은 지문 접촉 신호 감지에 민감하지 않은 패턴 내부가 식각된 형상인 것이 더욱 바람직하다. 이러한 식각된 형상의 감지 패턴으로부터, 높은 인식 패턴 충전율을 확보하는 것이 가능한 효과가 있다. More preferably, the sensing pattern 300 according to an exemplary embodiment of the present invention has an etched shape inside the pattern which is not sensitive to fingerprint touch signal sensing. From this etched shape sensing pattern, it is possible to secure a high recognition pattern filling rate.
본 발명에 따르면, 화면상에 지문인식 센서를 구현하는 경우, 터치스크린과 지문인식 센서가 오버랩될 수 밖에 없어, 특정 영역에서 터치스크린이 동작되지 않는 문제점을 해결할 수 있다. According to the present invention, when the fingerprint sensor is implemented on the screen, the touch screen and the fingerprint sensor cannot but overlap each other, thereby solving the problem that the touch screen does not operate in a specific area.
도 8 은 본 발명의 실시예에 따른 다이아몬드 패턴 방식을 도시하는데, 다이아몬드 패턴은 송신 패턴과 수신 패턴을 모두 최대한 한 면에 노출시키기 위한 패턴으로서, 채널들을 상호 직교시켜 형성한다. FIG. 8 illustrates a diamond pattern method according to an exemplary embodiment of the present invention. A diamond pattern is a pattern for exposing both a transmission pattern and a reception pattern to one side as much as possible, and is formed by mutually orthogonal channels.
따라서, 도 8b에 도시한 바와 같이, 송신 패턴과 수신 패턴이 겹쳐지는 극히 일부분 영역인 overlap 영역 외에서는 패턴 레이어가 겹쳐지지 않아, 투과율 문제를 해결하는 것이 가능하다.Therefore, as shown in FIG. 8B, the pattern layer does not overlap except the overlap region which is a very partial region where the transmission pattern and the reception pattern overlap, and thus the transmittance problem can be solved.
