Description

Security medium {SECURITY MEDIA}

The present invention relates to a security medium, and more particularly to a security medium for user authentication.

The touch screen is one of the input devices that reads data necessary for communication with a device or a device in addition to voice, and is attracting attention due to its simplicity and convenience of use. Touch screens are divided into resistive (or pressure sensitive) and capacitive (or capacitive) methods according to the principle of operation. Recently, a surface acoustic wave (SAW) method for detecting a touch using ultrasonic technology has been developed.

The resistive film is a method of sensing pressure by sensing pressure, and is implemented in a plurality of layers. On the outside is a soft, scratch-resistant layer, followed by two layers that protect the liquid crystal and two layers of electricity. When the outer flexible membrane is pressed, the resistive touch screen detects the input point by detecting a change in current and resistance generated when the two layers of electricity touch each other.

The capacitive method is a method of sensing motion by using static electricity of the human body, and is implemented by coating a highly conductive compound on the liquid crystal glass unlike the resistive film method. A capacitive touch screen senses a point of contact as electrons flowing on the liquid crystal move to the finger when the finger touches.

The capacitance type can reduce the thickness of the touch panel by 1mm as compared with the resistance film type, improve the durability of the touch pad, reduce the possibility of malfunction due to external pressure, and enlarge or reduce the image with two fingers As multi-touch capability is available, recently, touch screens tend to favor capacitive touch screens.

In addition, the surface acoustic wave method is a method in which ultrasonic waves are flowed on the surface glass to recognize the coordinate where the touch is made, which is advantageous in that sensitivity is good when any point is pressed because there is no dead zone.

Recently, a user is authenticated by inputting a password by touching a number, figure, or letter displayed on the touch screen of the target device when authenticating a user by attaching a touch screen to a computer, a smartphone, a personal information terminal, or a financial automatic machine. to be. Recently, there has been introduced a method of starting a touch at the starting point and dragging it to the end point instead of touching the numbers and the like displayed on the touch screen one-time.

However, the conventional authentication method is inconvenient that the user must memorize the password in advance, and thus, it is difficult to use a complicated and long password, and thus weak in security because the same password is generally used in a plurality of authentication procedures. have. In addition, the existing authentication method has a problem that the afterimage of the fingerprint due to the contact of the finger remains on the touch screen, there is a risk that the password is exposed to others.

1 is a view schematically showing a security medium according to a first embodiment of the present invention.

Referring to FIG. 1, the security medium 100 includes a plate 110, a conductor patch 120, and a protrusion 130.

First, the plate 110 is formed of a non-conductive material to form the body of the security medium 100. For example, the non-conductor material may include plastic, wood, rubber, paper, and the like.

In one embodiment, plate 110 may be embodied as a card. In this case, the plate 110 may be thinner so that the user can be stored in the wallet, and may be implemented in various ways such as square, triangle, circle, oval, and the like.

In another embodiment, the plate 110 may be implemented with a sheet of a flexible material. At this time, the plate 110 may be formed with an adhesive surface to be attached to one side of the painting, name plate, character goods, cards.

Next, the conductor patch 120 is formed of a conductor material on the first surface of the plate 110. That is, the conductor patch 120 may be implemented as a pure conductor, a semiconductor, or a device or a combination of devices having a specific resistance value, which may charge or discharge a charge.

The conductor patch 120 may be embodied as an oval (goggle), a flat hexahedron, an octahedron, a circular shape, and the like. In addition, the conductor patch 120 need not be limited in thickness, and may be printed thinly on the plate 110.

On the other hand, the conductor patch 120 constitutes an authentication pattern. The authentication pattern is used as a password for user authentication. In one embodiment, the authentication pattern may be different for each user. For example, a financial institution may assign a unique authentication pattern to each user for financial transactions. Accordingly, each user may have a different authentication pattern.

In another embodiment, the authentication pattern may be different for each service. For example, a web service provider may assign a unique authentication pattern to a person allowing web service access. In this case, the same web service user may be assigned the same authentication pattern. As another example, the web service provider may assign an authentication pattern according to a user's access authority. In this case, a user having the same access authority may be assigned the same authentication pattern.

In one embodiment, the conductor patch 120 may be removable. For example, when the user receives the security medium 100 to which the conductor patch 120 is pre-attached over the first side, the user removes the at least one conductor patch 120 so that a unique authentication pattern is formed. can do. On the contrary, when the user receives the security medium 100 without the conductor patch 120 attached to the first surface, the user may attach the at least one conductor patch 120 to form a unique authentication pattern.

Next, the protrusion 130 is formed of a conductor material on the conductor patch 120. In one embodiment, the protrusion 130 may be integrally formed with the conductor patch 120.

In addition, the protrusion 130 provides an electron transfer passage between the conductor patch 120 and the touch screen when the touch screen touches the touch screen of the target device. The touch screen is electrically connected to the conductor patch 120 through the protrusion 130.

Here, the target device may include a PC having a touch screen, a notebook computer, a personal digital assistant (PDA), a smart phone, and an ATM. The touch screen includes a color filter, a liquid crystal, and a thin film transistor as well as a touch screen integrated with a tempered glass that forms a touch integrally on the bottom of a cover window such as tempered glass, and an attachable touch screen that attaches a separate touch screen to an upper portion of the display. An in-cell touch screen that implements a touch recognition function is included in the configured display cell.

On the other hand, the projection 130 has a height of a predetermined value or more so that the security medium 100 can be in contact with the touch screen of the target device more than a predetermined area. Here, the constant area means a minimum area for the touch screen to detect the contact point.

Recently, it is common to put a protective case on a target device in order to protect the target device from an external impact. In this case, since a height difference occurs between the touch screen and the protective case, the user may have to apply a pressure to contact the security medium to the touch screen. It can also be mistaken. The protrusion 130 has a height greater than or equal to the height difference between the touch screen and the protective case in order to overcome the height difference and provide a user with convenience of contact.

It is sectional drawing which shows an example schematically.

4A is a perspective view schematically illustrating a third embodiment of a plurality of authentication patterns formed on the security medium of FIG. 1, and FIG. 4B is a third embodiment of a plurality of authentication patterns formed on the security medium of FIG. 1. It is sectional drawing which shows an example schematically.

The touch screen may detect a second authentication pattern composed of a plurality of second conductor patches 122 through the second protrusion 132, and perform user authentication using the detected second authentication pattern.

In this case, the second authentication pattern may be used in the authentication procedure of the same service as the first authentication pattern. For example, the first authentication pattern and the second authentication pattern may be used as a first password and a second password for a financial transaction. The user may use the financial transaction only when the second authentication is successful by inputting the second password again after the first authentication is successful by inputting the first password.

In addition, the second authentication pattern may be used in an authentication procedure of a service associated with the first authentication pattern. For example, the first authentication pattern may be used as a first password for unlocking the smartphone, and the second authentication pattern may be used for user authentication for using a call service or data service of the smartphone.

As another example, the first authentication pattern may be used as a first password for accessing a specific website, and the second authentication pattern may be used as a second password for using a specific web service provided by the specific website. Can be. Here, the specific web site represents a web site providing a web service by allowing access only to a specific group, and the specific web service represents a web service provided only to a user to whom the access right is granted.

The capacitance 140 is formed of a conductor material on one side of the plate 110 and is electrically connected to at least one of the first conductor patch 121 and the second conductor patch 122. The capacitive body 140 may be implemented by a copper plate having a conductor property, a semiconductor, a combination of a conductor and a non-conductor, a device having a specific resistance value, or a combination of devices. That is, the capacitive body 140 may be implemented as a conductor, a semiconductor, and a semiconductor device (for example, a capacitor and a resistor) through which charge can move.

In one embodiment, the capacitive body 140 may itself have a capacitance above a threshold. In this case, the capacitance 140 may supply capacitance to the first conductor patch 121 or the second conductor patch 122 having a capacitance less than a threshold value.

In another embodiment, the capacitive body 140 may be supplied with capacitance through the user's skin. In this case, the capacitance 140 may increase the touch sensitivity of the security medium 100 by providing the supplied capacitance to the first conductor patch 121 or the second conductor patch 122.

Although not shown in FIG. 5, in one embodiment, the capacitance 140 is a first capacitance electrically connected with the first conductor patch 121, and a second conductor patch 122 electrically connected with the second conductor patch 122. 2 may comprise a capacitance.

In one embodiment, the first conductor patch 121 may supply capacitance to the second conductor patch 122 as the capacitance 140, and the second conductor patch 122 may be the capacitance 140 as a capacitor. Capacitance may be supplied to the first conductor patch 121.

As a specific example, when the first conductor patch 121 and the second conductor patch 122 are formed on opposite surfaces, the first conductor patch 121 is in contact with the user's skin to contact the second conductor patch 122. Capacitance can be supplied. In contrast, the second conductor patch 122 may contact the user's skin to supply capacitance to the first conductor patch 121.

For example, when the user applies a force, the bent portion 150 may be bent along the concave groove to form a bent or restore the bent to a planar state.

By the bent portion 150, the first region may be formed relatively lower or higher than the second region. For example, when the first authentication pattern is input to the target device, the first area in contact with the touch screen may be lower than the second area in contact with the touch screen.

In addition, the bent portion 150 may have a height higher than or equal to a predetermined value so that the security medium 100 may be in contact with the touch screen of the target device by a predetermined area or more. Here, the constant area means a minimum area for the touch screen to detect the contact point.

Recently, it is common to put a protective case on a target device in order to protect the target device from an external impact, and a height difference occurs between the touch screen and the protective case. The bent part 150 may have a height greater than or equal to the height difference between the touch screen and the protective case in order to overcome the height difference and provide a user's convenience of contact.
