Description

  The present invention relates to a security technology for an information communication terminal, and more particularly to an information communication terminal provided with a lock release method and a lock mechanism for an information communication terminal using a gesture pattern.

  There is known a technology in which an information communication terminal can be used by performing a predetermined gesture operation on the touch screen in the information communication terminal. This is because of security considerations and prevents the use of information communication terminals by third parties. The predetermined gesture operation is, for example, tracing a point arranged in a 3 × 3 grid displayed on the touch screen with a fingertip or the like.

  More specifically, when the pattern by the gesture operation matches the lock pattern that is the key for unlocking, the unlocking mechanism works and the information communication terminal becomes usable. This unlocking method does not involve numbers or letters, unlike the unlocking method using a password. Therefore, there is no fear that these character codes are leaked or stolen. On the other hand, when tracing the touch screen with a fingertip or the like, there is a possibility that a lock pattern is estimated from traces of sebum remaining on the touch screen.

  An example of such a method for unlocking an information communication terminal is described in Patent Document 1. The lock release method described in Patent Document 1 is controlled so that the user who inputs the lock pattern does not trace the same position on the touch screen every time the user tries to release the pattern lock. For example, display that changes the upper direction of the touch screen (that is, the up / down / left / right direction of the lock pattern input to the grid pattern changes), displays the grid pattern enlarged or reduced, and touches Displaying a grid pattern at a position shifted from the center of the screen is described. As a result, the user does not trace the same position on the touch panel every time, and the risk that a third party can guess the lock pattern from the fingerprint trace remaining on the touch screen is reduced.

JP 2013-16115 A

  However, the unlocking method described in Patent Document 1 has the following problems. According to the method described in Patent Document 1 in which the upward direction is changed, enlarged or reduced, or shifted from the center position with respect to the lattice-like pattern, the trace of the pattern traced by the fingertip or the like on the touch panel is displayed. Diversity increases. Therefore, the portion that traces the touch screen is not at the same position every time. On the other hand, the similarity of figures remains between the traces of the input pattern remaining on the touch screen, and in particular, the grid pattern is displayed by enlarging or reducing it or shifting it from the center position. If you do, it is remarkable. Therefore, although the variety of traces of patterns traced by a fingertip or the like on the touch panel is increased, there is a risk that a lock pattern is inferred from the similarity remaining between these traces.

  In addition, when displaying the lattice pattern in an upward direction, the traces traced by the fingertip or the like on the touch panel are superimposed on each other. Therefore, it is difficult to guess the lock pattern from the trace of the superimposition traced by the fingertip on the touch panel. However, when another person is peeking at the movement of the fingertip, the lock pattern may be guessed by another person from the movement pattern that is similar to the lock pattern.

  As described above, according to the related unlocking method described in Patent Document 1, a lock pattern for unlocking the information communication terminal from a trace of an input pattern remaining on the touch screen or a peep by another person is a third party. There was a problem that could be guessed.

  An object of the present invention is to provide an information communication terminal unlocking method and a lock mechanism that solve the above-described problem that a lock pattern for unlocking an information communication terminal can be guessed by a third party. It is to provide a communication terminal.

  The unlocking method of the information communication terminal according to the present invention detects the vertical direction of the display unit of the information communication terminal, sets a reversal axis in a predetermined direction with respect to the vertical direction, and sets a pre-registered lock pattern with respect to the reversal axis. The reversed lock pattern reversed and held, the input gesture pattern is received, the gesture pattern is compared with the reversed lock pattern, and the lock is released when the gesture pattern matches the reversed lock pattern.

  The information communication terminal equipped with the lock mechanism of the present invention detects an external sensor that detects the vertical direction of the display unit of the information communication terminal and a gesture pattern input through a predetermined display point displayed on the display unit. A touch screen, a control unit that sets an inversion axis in a predetermined direction of the display unit based on the vertical direction, and a storage unit that holds an inversion lock pattern obtained by inverting a pre-registered lock pattern based on the inversion axis. The control unit compares the gesture pattern and the reverse lock pattern, and releases the lock when they match.

  According to the information communication terminal unlocking method and the information communication terminal including the lock mechanism of the present invention, it is possible to reduce the risk that a lock pattern for unlocking the information communication terminal is guessed by a third party.

  Next, embodiments for carrying out the present invention will be described with reference to the drawings. In the following description, components having the same function may be denoted by the same reference numerals and description thereof may be omitted.

(First embodiment)
FIG. 1 is an overview diagram showing a configuration of an information communication terminal including a lock mechanism according to the first embodiment of the present invention. 1 is a diagram illustrating an overview of an information communication terminal 1, and the information communication terminal 1 includes a touch screen 20 and a housing 10.

  The touch screen 20 has a display function and a touch sensing function. Using the display function, the grid point 100, the direction display 300, and the like are displayed on the touch screen 20. The grid point 100 is, for example, a group of points arranged in a 3 × 3 grid pattern. The movement of the fingertip (gesture operation) following an arbitrary point in the 3rd row and the 3rd column is detected using the touch sensing function.

  In addition, the direction display 300 indicates a mode of a pattern to be input along a lattice point. For example, it indicates whether the pattern to be input along the lattice points is a left-right inversion, up-down inversion, up-down left-right inversion pattern, or the like of the lock pattern. Moreover, in the state which is not reversed, it may show the up-down and left-right directions of the grid-like points.

  FIG. 2 is a block diagram illustrating a configuration of the information communication terminal 1 including the lock mechanism according to the first embodiment of the present invention. The information communication terminal 1 provided with the lock mechanism includes at least a touch screen 20, an external sensor 30, a control unit 40, and a storage unit 50. Furthermore, a radio unit, a voice output unit, a voice input unit, and the like may be included.

  The external sensor 30 includes an acceleration sensor 31, a gravity sensor 32, and the like. The posture of the information communication terminal 1 is detected using these sensors not shown. That is, the touch screen 20 is detected as to whether the screen is vertically long, horizontally long, or upside down.

  Based on the detection result of the external sensor 30, the control unit 40 determines an inversion axis that is an axis of symmetry between the pattern input along the lattice points and the lock pattern in a predetermined direction with respect to the touch screen 20. Here, inversion in a predetermined direction includes upside down, left and right inversion, up and down and left and right inversion.

  The storage unit 50 holds the lock pattern itself (original) or a plurality of states such as a state in which the pattern is reversed based on the above-described reversal axis. The lock pattern itself (original version) is registered in advance, and the registration location may be in the information communication terminal or in an external device such as a server.

  Next, the unlocking method will be described. The control unit 40 selects an arbitrary pattern from four patterns, that is, an input gesture pattern that is horizontally reversed, vertically reversed, vertically reversed horizontally reversed, or a pattern that is not reversed with respect to the lock pattern. The control unit 40 notifies the user of information about the reversal axis regarding the selected pattern. The notification to the user is performed, for example, by reversing the positive / negative of the lattice point, using the direction display 300, or the like. The user inputs a gesture pattern corresponding to the notified information about the reverse axis.

  After the input operation by the user, the control unit 40 compares the gesture pattern input to the touch screen 20 of the information communication terminal 1 with the selected lock pattern. When the input gesture pattern matches the selected lock pattern, the control unit 40 releases the lock. If they do not match, the control unit 40 does not release the lock and notifies the user that they do not match. Further, in the case where they do not match, the reverse axis may be reset and new information about the reverse axis may be notified to the user.

  Note that the notification to the user is not limited to the positive / negative reversal of the lattice point portion described above. For example, all the displays on the touch screen 20 may be reversed positive / negative. Alternatively, only a part of the lattice point may be reversed positive and negative, and information about the reversal axis may be notified to the user by the positive / negative reversal position.

  FIG. 3 is a diagram of a gesture pattern for explaining the information communication terminal including the lock release method and lock mechanism of the information communication terminal according to the first embodiment of the present invention. A gesture pattern 200 in FIG. 3A is a lock pattern registered in advance. A gesture pattern 210 in FIG. 3B is a case where a pre-registered lock pattern is reversed left and right. In the case of FIG. 3B, the control unit 40 notifies the user of “inversion” and “left-right direction” as “inversion axis information regarding the selected lock pattern”. In the case of FIG. 3A, the control unit 40 does not notify the “inversion” information.

  FIG. 4 is a diagram illustrating a display mode for explaining the information communication terminal including the lock release method and the lock mechanism of the information communication terminal according to the first embodiment of the present invention. On the touch screen 20, grid-like points 130 with positive / negative reversal are displayed. With respect to the “inverted axis information regarding the selected lock pattern”, the information of “inverted” is notified to the user using the display of the grid-like points 130 that have been positive / negative inverted.

  As described above, the information communication terminal provided with the lock release method and the lock mechanism of the information communication terminal according to the present embodiment uses the inversion pattern of the lock pattern as an input pattern, such as a fingertip on the touch panel. The pattern traced by the image is mixed with a mirror-inverted pattern. Therefore, the possibility that the lock pattern is estimated from the trace of the input pattern or the peep is reduced compared to the related release method. This is because, even if the lock pattern is changed upward, enlarged or reduced, or shifted from the center position, as in the related release method, the similarity of the figure between the input pattern and the lock pattern Sex is maintained. Therefore, in the related release method, there is a high possibility that a lock pattern is inferred from the similarity between them. Thus, according to the information communication terminal provided with the lock release method and the lock mechanism of the information communication terminal according to the present embodiment, there is a risk that a lock pattern for unlocking the information communication terminal is guessed by a third party. It becomes possible to reduce.

(Second Embodiment)
FIG. 5 is a diagram illustrating a display mode for explaining the information communication terminal including the lock release method and the lock mechanism of the information communication terminal according to the second embodiment of the present invention. The difference between the display mode diagram shown in FIG. 5 and the overview diagram shown in FIG. 1 is the arrangement of points displayed in a grid pattern. That is, the points displayed in a grid pattern according to this embodiment are arranged in 4 rows and 3 columns. That is, it is not a square arrangement such as 3 rows and 3 columns, but a rectangular arrangement corresponding to the aspect ratio of the touch screen. This arrangement has the following operations and effects.

  First, as the number of points increases from 3 rows 3 columns to 4 rows 3 columns, the variation of gesture pans increases. This increases the difficulty of unlocking by estimating the lock pattern. On the other hand, in the method of changing the vertical and horizontal directions of the grid pattern as in the related cancellation method, the number of grids in the vertical direction and the horizontal direction needs to be the same. Therefore, the related cancellation method cannot cope with such a 4 × 3 point arrangement (rectangular point arrangement).

  Here, as the rectangular arrangement, an arrangement of 4 rows and 3 columns is described here, but the arrangement is not limited to this example. Other arrangements according to the aspect ratio of the touch screen are also possible.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these are also included in the scope of the present invention. Absent. For example, in the step of unlocking, a predetermined external device such as a device in a home network may be unlocked via an information communication terminal. Moreover, you may cancel the lock | rock of a predetermined | prescribed external apparatus in connection with the unlocking | release of an information communication terminal.
