The present invention relates to a system for securing security equipped with a touch screen input device and a method for implementing the same.

The touch screen input device detects the location of a person's hand or an object on a screen or a specific location on the screen without using a keyboard so that the location of the touch screen can be processed by the stored software. This refers to a screen that allows input data to be received directly from the screen. Touch screen input devices, which are new input methods that can replace input devices such as mice and keyboards, are currently being applied to many fields such as PDAs, LCDs, CRTs, banks and government offices, various medical devices, and traffic guidance. In particular, in the case of the ATM machine used in the bank, the user can be authenticated by entering a password to use the service.

As such, in a system equipped with a conventional touch screen input device, a password is mainly used to protect data stored in the system. If the user has previously set a password on the system, the system outputs a screen for entering the password to the touch screen input device as a standby screen in the next use. Subsequently, the system receives a password from the user through the touch screen input device, and allows the use of the system to access the data when the input password matches the password stored in the system.

 However, in the case of a security method of a system using such a password, there is a risk that important data may be exposed to an unspecified number due to user's carelessness or the leakage of a password by a hacking program. In addition, each time you use the system, you must enter a password every time, which can be a hassle for users.

As described above, the user inputs a password into the system, which is inconvenient to enter a password every time for the use of the system and the security of data stored in the system due to the password leakage.

Accordingly, the present invention provides a system for securing security equipped with a touch screen input device and a method for implementing the same.

In accordance with another aspect of the present invention, there is provided a system for securing security with a touch screen input device, comprising a radio frequency identification (RFID) tag in which predetermined identification information is recorded. A touch input mechanism for providing a touch input to the touch input device, and operated by the control unit when there is a touch input of the touch input mechanism to the touch screen input device to receive identification information recorded in the RFID tag of the touch input mechanism. A RFID reader for receiving and reading, a memory storing predetermined identification information, and a touch input of the touch input device is detected through the touch screen input device to activate the RFID reader and read by the RFID reader. The identification information recorded in the RFID tag of the touch input device If there is a match with the stored identification information is characterized in that it comprises a control unit for allowing the use of the system.

In addition, a touch screen input device for performing a touch input by a touch input mechanism equipped with a radio frequency identification (RFID) tag in which predetermined identification information is recorded, an RFID reader, and a memory in which predetermined identification information is stored. A method for securing security in a system, the method comprising: operating the RFID reader when a touch input of the touch input device to the touch screen input device is detected, and identifying information recorded on the RFID tag of the touch input device. And receiving and reading by the RFID reader, and allowing the use of the system when the read identification information matches with the identification information stored in the memory.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

The present invention implements a system and method having a touch screen input device for securing security. To this end, the present invention first registers the identification information recorded in the RFID tag of the touch input device in the memory. Thereafter, when the touch screen input device has a touch input of the touch input device, the RFID reader starts to operate according to the authentication result of the touch input device. For this authentication, the RFID reader receives and reads identification information from the RFID tag of the touch input device. The system then compares the read identification information with the identification information stored in the memory and permits use only if they match. As described above, the present invention has an advantage that the user can effectively control the use of the system by one touch operation without inputting a password every time.

Prior to describing the present invention, the RFID used in the present invention will be briefly described. Radio Frequency Identification (RFID) is a technology that can identify an object, an animal, or a person by using a radio frequency (RF). RFID is semi-permanent because there is no obstacle due to malfunction of the reader, and it is impossible to forge and tamper with data, so it can maintain perfect security. The present invention proposes a method for easily and simply accessing a system requiring security using the features of RFID.

Hereinafter, an example of a system having a touch screen input device using RFID according to an embodiment of the present invention will be described with reference to FIG. 1.

The system comprises an RFID reader 106 having a touch screen input device (hereinafter referred to as a touch screen) 104 and a stylus pen 100 equipped with an RFID tag. First, the RFID tag 102 is mounted on the stylus pen 100. The RFID tag 102 may be attached to the exterior of the stylus pen 100, or included in the stylus pen 100 in a manner that is mounted therein. In the exemplary embodiment of the present invention, the stylus pen 100 is used as a touch input mechanism for making a touch input to the touch screen 104. However, the touch input device may be changed by a writing instrument that is round and smoothly processed so that the card or the end portion of which the RFID tag capable of touch input is mounted on the touch screen is not damaged. A detailed operation of the component will be described with reference to FIG. 2.

2 is a block diagram of a system including a touch screen input device using RFID according to an embodiment of the present invention. As shown in FIG. 2, the RFID tag 200 is mounted on a stylus pen. The RFID tag 200, also called a wireless tag, is composed of an IC (Integrated Circuit) chip and an antenna for storing information. The memory capacity of an IC chip varies from 25 bits to 512 kilobytes or more, and the memory types also vary from read-only, read-write, write-once, and the like. In an embodiment of the present invention, the RFID tag 200 stores unique identification information assigned thereto.

The touch screen 202 receives data from a user in a manner of directly receiving a touch input on the screen using a touch input device such as a stylus pen. In the embodiment of the present invention, the touch screen 202 outputs a screen for receiving a password and receives a touch input directly from a stylus pen equipped with an RFID tag 200. Meanwhile, the touch screen 202 outputs a screen for directly inputting a password from the user when the identification information recorded in the RFID tag 200 of the stylus pen does not match the identification information stored in the memory 206.

The RFID reader 204 generates a radio frequency (RF) signal for receiving identification information from the RFID tag 200 of the stylus pen under the control of the controller 208, and outputs from the RFID tag 200 by the RF signal. Receive and read the identification information. The RFID reader 204 then transfers the read identification information to the controller 208. The RFID reader 204 does not normally operate to reduce power loss, but preferably operates when there is a touch input of the stylus pen on the touch screen 202. Specifically, the conventional RFID reader wasted a lot of power by always outputting the RF signal for detecting the RFID tag while the system is operating. However, according to an exemplary embodiment of the present invention, since the controller 208 controls the RFID reader 204 to operate only when there is a touch input of the touch input device on the touch screen 202, power loss can be greatly reduced. There is this.

The memory 206 is a nonvolatile storage device, in which identification information predetermined by a user is stored. In addition, the password of the system preset by the user is stored in the memory 206 separately from the identification information.

The controller 208 controls the RFID reader 204 to start operation when a touch input of the stylus pen is detected on the touch screen 202. Subsequently, the controller 208 receives the identification information from the RFID reader 204 which has started operation. Then, the controller 208 determines whether the read identification information and the identification information stored in the memory 206 match, and permits the use of the system only when they match. Meanwhile, when the identification information recorded in the RFID tag does not match the identification information stored in the memory, the stylus pen may be new or illegally used by others. Therefore, the control unit 208 needs to authenticate the user in each case. To this end, the controller 208 displays a password input window for user authentication on the touch screen 202. The controller 208 receives the password from the user and checks whether the password matches the password stored in the memory 206, and permits the use of the system only when the password matches. In addition, when there is a touch input of a stylus pen including an unregistered RFID tag after the use of the system is determined through a password, the controller 208 registers the identification information of the new RFID tag as new identification information in the memory 206. To be able.

Table 1 shows identification information and passwords stored in the memory 206 according to the embodiment.

NO. RFID Identification Information password One A4908833 4568 2 T9873427 2164 3 P6542801 7685

As shown in Table 1, the memory 206 stores identification information of an RFID tag registered by a user in advance. The memory 206 also stores a password registered by the user. Thus, when identification information is received from the RFID tag 200, the controller 208 compares whether there is a match with the RFID identification information of Table 1, and permits the use of the system when there is matching identification information. As such, the method of authenticating the user with the RFID tag has the advantage that the user can effectively control the use of the system with only one touch operation while eliminating the inconvenience of having to input the password every time.

The controller 208 may receive a password if the identification information of the RFID tag does not match the identification information stored in the memory 206. Accordingly, the control unit 208 compares the input password with the password of Table 1 and permits the use of the system if there is a matching password. The change of password may be made through a program that enables execution of at least one of adding, modifying or deleting a new password to the system. In addition, when a touch input device including an RFID tag in which new identification information is stored makes a touch input with the touch screen 202, a program for storing new identification information may be installed to facilitate user's replacement of the RFID tag. can do.

Next, a control flow for providing a security function using a stylus pen in a system according to an embodiment of the present invention will be described with reference to FIG. 3.

First, in step 300, the controller 208 determines whether a touch input is made by touching the password input screen of the touch screen 202, and when the touch input is made, operates the RFID reader 204 in step 302. Normally, the RFID reader 204 is turned off without operation before there is a touch input from the stylus pen. On the other hand, if there is no touch input due to no contact of the stylus pen, the controller 208 returns to step 300 again.

In step 304, the controller 208 operates the RFID reader 204 to receive identification information of the RFID tag 200. In operation 306, the controller 208 determines whether the read identification information matches the identification information stored in the memory 206. Thus, if there is a match, the controller 208 proceeds to step 308 to switch to a system available mode, and if not, proceeds to step 400 of FIG. 4. Here, symbol A is used to show that step 306 of FIG. 3 and step 400 of FIG. 4 are connected.

 4 is a control flowchart for registering a new RFID tag according to an embodiment of the present invention.

If the identification information read from the RFID reader 204 does not match the identification information stored in the memory 206 of the system, the controller 208 outputs a screen for inputting a password to the touch screen 202 in step 400. . In operation 402, the controller 208 determines whether a password is input. If the password is input, the controller 208 checks the input password in operation 404. If the password has not been entered, the controller 208 returns to step 402 and waits for input of the password.

In step 406, the controller 208 determines whether the input password matches the password registered in the memory 206. If the passwords match, the control unit 208 switches to the system usable mode in step 408, and terminates the use of the system if the passwords do not match.

If the password is matched and the use of the system is permitted, the control unit 208 recognizes that the user is a legitimate user as in the case of being authenticated with the RFID tag. Thus, the user can further register identification information of the new RFID tag in the memory. Accordingly, in step 410, the control unit 208 displays a message on the touch screen 202 asking whether to newly register the identification information of the RFID tag that has not been used by the system in the memory 206. The controller 208 determines whether new registration is selected in step 412, and if so, proceeds to step 414 to further register identification information of the new RFID tag in the memory 206.

Meanwhile, the controller 208 determines whether the identification information of the new RFID tag is the correct format that can be registered without overlapping the identification information of the other RFID tag stored in the memory 206 and stores the identification information of the RFID tag in the correct format. You can register at That is, even if the identification information of the RFID tag that does not conform to the format stored in the memory 206 such as the digits or the letter and number combination method is received, registration is impossible.

In the detailed description of the present invention, specific embodiments have been described, but the type of touch input device and the type and number of identification information stored in the memory may be modified in various ways without departing from the scope of the present invention. Of course. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.

As described above, the present invention has the advantage that the user can easily access the system with one touch operation without inputting a password every time. In addition, it has the advantage that the power consumption can also be efficient by operating only the RFID reader when needed.
