Description

Specification

Name of invention: Fingerprint recognition hacking prevention device for mobile terminal and surface member for fingerprint hacking prevention and fingerprint hacking prevention method

[1] The present invention relates to a fingerprint recognition anti-hacking device for a mobile terminal and its fingerprint hacking.

Regarding the prevention method, the screen lock function can be performed in more detail by unlocking the screen through the fingerprint recognition function in detail and simultaneously allowing the menu shortcut function to be performed in a single operation without leaving the hackable fingerprint station on the surface of the mobile terminal. The present invention relates to a fingerprint recognition hacking prevention device for a mobile terminal and a fingerprint hacking prevention method for performing hacking prevention of fingerprint recognition.

Background

[2] In general, four-digit password authentication is the most common means of authenticating a user's identity, but hacking on commonly used four-digit passwords is easy for hackers.

[3] Recently, with the rapid development of online remote data transmission and reception technology, the situation of accessing and verifying the identity online from financial transactions to the start-up of cars is increasing day by day, while security has adhered to the traditional password input method.

[4] However, as mentioned earlier, a few-digit password is so easily hacked that security professionals are now offering a variety of alternatives, ranging from biometrics to password replacement apps.

[5] Most notable is biometrics, identity recognition using face, voice, fingerprint, and iris recognition, with the advantage that such biometrics are not subject to change or loss. Apple has added fingerprint recognition to the newly released iPhone 5S.

[6] However, Apple's new iPhone 5S fingerprint recognition method was hacked in two days. The hacking method was applied to the scratch-resistant film or home button attached to the iPhone 5S body or the front of the LCD. It is a method of securing a buried fingerprint station with a tape or scanning it with a scanner to obtain image data and attaching it to a fake finger using the image to make it available for a fingerprint recognition sensor.

[7] In particular, the iPhone 5S has a built-in fingerprint sensor in the flaw button, so it is likely that the most complete fingerprint station remains on the surface of the home button. Therefore, the smartphone with the fingerprint recognition has the convenience of its function. Although it is very high, it is difficult to use fingerprint recognition technology completely, unless the technology for hacking is developed.

[8] On the other hand, when the smartphone is unlocked, the smartphone authenticates the pattern to authenticate the user. Alternatively, there is a function to perform password authentication and unlock the screen, but this function simply unlocks the screen, and the user clicks on another icon after the screen is unlocked to confirm the call or message. Even when trying to operate frequently used icons such as cameras, there was a problem that two operations such as unlocking the screen and manipulating the corresponding icons are necessary and inconvenient.

[9] In addition, users of smartphones, such as the iPhone 5S with fingerprint recognition technology, may need to expose call history, text messages, or various data stored on the smartphone to the person who is not a hack.

[10] However, since exposure of such data is related to privacy, we try to prevent exposure with the hidden function. However, if the acquaintance is aware of the hidden function, there is still no way to not expose the data related to personal privacy.

8 is an anti-fingerprint hacking prevention for mobile terminals according to the first embodiment of the present invention.

It is a flow chart showing the signal flow of the device.

[69] First, anti-fingerprint hacking for mobile terminals according to the first embodiment of the present invention.

The device 100 is configured inside the mobile terminal 2, and whether the fingerprint data is a reference for fingerprint authentication may be stored in the mobile terminal 2, or may be stored in a remote server (not shown).

[70] For example, if the purpose of fingerprint authentication is micropayment through mobile terminal (2), or in case of message confirmation or email confirmation, it is preferable that the base fingerprint data is stored in mobile terminal (2). In the case of online shopping such as this, it is also possible to store reference fingerprint data for fingerprint authentication in a corresponding open market or a Bansa server and perform authentication processing.

[71] First, in the embodiment of the present invention, the reference fingerprint data is stored in the mobile terminal (2).

Only what is stored will be described.

[72] With reference fingerprint data stored in the mobile terminal (2),

In the fingerprint interlocking shortcut menu setting unit 108 configured in the fingerprint recognition hacking prevention device for a mobile terminal according to an embodiment, a shortcut menu for each moving direction is set for each user.

[73] With the shortcut menu set, the control unit 116 turns the fingerprint recognition sensor unit 104 on.

Determines whether a fingerprint input signal is received.

In other words, if the user is in close contact with the finger to the fingerprint recognition sensor 104, the fingerprint recognition

The sensor unit 104 scans the fingerprint data of the user.

[75] Then, the fingerprint authentication processing unit 106 replaces the fingerprint data with the reference fingerprint data.

In comparison, preliminary fingerprint authentication is performed.

[76] Preferably, the fingerprint image scanned through the fingerprint sensor ₍₁₀ 4) has a display control section 112 controls to be displayed on the screen of the mobile terminal 2 during the time that the fingerprint is scanned.

[77] Thus, the user can view the screen of the mobile terminal 2 so that his fingerprint is scanned.

You can check . In addition, the screen controller 112 may control the advertisement data to be output at the bottom of the fingerprint image. At this time, the advertisement data may be provided at the bottom of the fingerprint image to increase the attention to the advertisement.

[79] On the other hand, if the pre-fingerprint authentication fails, information about the fingerprint authentication failure is displayed on the screen.

The screen controller 112 is controlled to output, and upon successful preliminary fingerprint authentication, the controller 116 resets the fingerprint recognition sensor 104 and receives a new fingerprint input signal.

[80] In other words, the present invention performs multiple fingerprint authentication, thus preparing the first fingerprint authentication.

Fingerprint authentication, the second fingerprint authentication is the final fingerprint authentication, the second fingerprint authentication is to determine whether a crushed fingerprint signal is applied.

Accordingly, the fingerprint authentication processing unit 106 crushes the input fingerprint data.

Judging whether it is a signal, judging whether a crushed fingerprint signal is applied or not, so that the final authentication is completed is to allow the user to erase the fingerprint station on the fingerprint recognition sensor unit 104.

At this time, in the case of a fingerprint crush signal, the fingerprint authentication processing unit 106 processes the final fingerprint authentication success.

[83] Preferably, while inducing the user's aggressive sprinting

In order to enhance the user's convenience, the present invention allows the fingerprint recognition unit 104 to input a finger movement direction signal to activate the shortcut menu.

Accordingly, by inputting the fingerprint crush signal to the fingerprint recognition sensor unit 104, the direction detection processing unit 110 detects the direction of finger movement, and the control unit 116 controls the screen control unit 112. To activate the shortcut menu that matches the corresponding direction.

More specifically, in order to detect the direction through the fingerprint recognition unit 104, the direction detection processing unit 1 10 performs a chopping operation of repeatedly resetting the fingerprint recognition unit 104 at a predetermined time interval. The new fingerprint image is input at each time interval, and the finger movement direction is detected by the amount of change in the fingerprint image.

However, in the fingerprint recognition anti-hacking device 100 for a mobile terminal according to the first embodiment of the present invention, a direction input for activating a shortcut menu may be input in addition to the fingerprint recognition sensor unit 104. In particular, in case of inputting a shortcut menu selection signal from the screen, it is preferable to drag the text data or advertisement data to the screen of the mobile terminal 2 in a specific direction. By moving, it is preferable to control the direction detection processing unit 110 so that the shortcut menu set in the corresponding direction is driven.

Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings.

9 is an anti-fingerprint hacking prevention for the mobile terminal according to a second embodiment of the present invention.

Drawing showing the voice authentication status with additional authentication on the device.

The anti-hacking device 100 enhances the privacy of the personal information by unlocking the screen through the fingerprint recognition function and simultaneously allowing the shortcut menu function to be performed through voice authentication for a specific word or sentence.

[90] User identification via password entry or fingerprint image shows good security for certain third parties to view, but inevitably requires unlocking of the mobile terminal (2) or identification of e-mail and messages for viewing. Key

For acquaintances such as, for example, wife,

It is more important to hide folders or files and not know whether to use the file hiding service rather than security.

Therefore, according to the second embodiment of the present invention, the fingerprint recognition prevention for mobile terminals is prevented.

The device 100 provides a secret menu shortcut service so that a shortcut to the secret menu is performed through fingerprint authentication and voice authentication.

That is, since fingerprint authentication is fingerprint authentication through the fingerprint authentication processing unit 106, the fingerprint authentication means the same fingerprint authentication as that of the first embodiment in which the fingerprint is processed only when the fingerprint signal is inputted.

[93] Voice authentication does not mean that the user's voice is authenticated. Voice authentication does not mean that a word or sentence registered by voice in advance is matched by voice, and the voice recognition function exists in the current mobile terminal (2). So you can use it to perform voice recognition.

[94] In the case of voice recognition, it is very difficult for them to know which words or sentences are registered by how many syllables they are using.

[95] Therefore, anti-fingerprint hacking prevention for mobile terminals according to the second embodiment of the present invention.

The device 100 further includes a set word comparison unit 118 for additionally performing user voice authentication for a preset word or sentence in a state in which the fingerprint authentication is completed, and the control unit 116 performs fingerprint authentication and voice authentication. If all succeed, control whether to turn off incognito mode, which is whether the menu is displayed on the screen.

Hereinafter, a third embodiment of the present invention will be described in detail with reference to the drawings.

10 is an anti-fingerprint hacking prevention for a mobile terminal according to a third embodiment of the present invention.

Figure showing second fingerprint authentication and voice authentication status as additional authentication to the device.

Referring to this, preferably, in order for the secret mode to be released using the fingerprint recognition hacking prevention device 100 for a mobile terminal according to the third embodiment of the present invention, the fingerprint authentication processing unit 106 is different from each other. It is also possible to receive and authenticate the fingerprint of a finger multiple times.

[99] Even in this case, since it is difficult for an acquaintance to know which finger is registered as the second fingerprint, in addition to a plurality of fingerprint authentications, the security level is very high. . Accordingly, the fingerprint recognition anti-hacking device for a mobile terminal according to the third embodiment of the present invention has a user voice for a preset word or sentence in a state where fingerprint authentication is completed through the fingerprint authentication processing unit 106. An additional setting word comparison unit 118 for performing authentication is further included, and if the control unit 116 is successful in both fingerprint authentication and voice authentication, a secret mode in which a hidden folder or a menu is displayed on the screen is included.

Control to release.

In this case, in order to release the incognito mode, it is preferable that the fingerprint authentication processing unit 106 receives the fingerprints of different fingers a plurality of times and authenticates them.

Meanwhile, the fingerprint recognition hacking prevention device for a mobile terminal, the surface member for fingerprint hacking prevention, and the fingerprint hacking prevention method according to an embodiment of the present invention are not limited to the above-described embodiments, but the scope does not depart from the technical gist of the invention. Various changes are possible within.
