Description

Unlocking method and device and electronic device thereof

technical field

The present invention relates to an unlocking method and device and its electronic device, and in particular to an unlocking method and device using pattern encryption and its electronic device.

Background technique

With the advancement of technology, a large number of various electronic devices come out, including many clamshell electronic devices, such as notebook computers. Such a design can not only save space (such as disposing the screen on the front cover), but also protect the body of the electronic device from accidentally touching the upper parts (such as buttons) due to external force.

In order to prevent the front cover of the electronic device from shaking easily during movement, a switch is provided to control the opening of the front cover. Common opening methods for flip-top electronic devices include push-rod, push-button, push-type or magnetic upper cover to lift the front cover of the electronic device, such as using a push-rod switch to open the front cover of a notebook computer. However, for users with inflexible hand movements, it is often not easy to open because the design of the knob (Knob) is too small. On the other hand, the front cover switch design of general clamshell electronic devices has no encryption function, and the common encryption mechanism on the market is only for software locks. Nowadays, most people rely more and more on electronic devices, and therefore more and more attention is paid to safety considerations.

Detailed ways

FIG. 1 is a block diagram of an electronic device according to an embodiment of the invention. Referring to FIG. 1 , the electronic device 100 includes an unlocking device 110 and a control unit 120 . In this embodiment, the electronic device 100 is, for example, a notebook computer, a tablet computer, or a personal digital assistant, and the control unit 120 is, for example, a microcomputer magnetic lock or a software lock, which is used to protect the electronic device 100 for specific persons. Wherein, the unlocking device 110 can be used to open a lock of the electronic device 100 (for example, the control unit 120 ). That is, the control unit 120 is used to enable the hardware configuration or software of the electronic device 100 so that it can operate normally. For example, the control unit 120 is used to open the front cover of the electronic device 100 , or the control unit 120 is used to enter the operating system of the electronic device 100 .

The unlocking device 110 includes an input interface 101 , a storage unit 103 and a processing unit 105 . In this embodiment, the input interface 101 is used to receive the input pattern into the buffer memory (not shown) of the storage unit 103, and then send the input pattern to the processing unit 105, so that the processing unit 105 can Preset patterns are compared to determine whether to drive the control unit 120 to enable the electronic device 100 to operate normally.

The input interface 101 includes a plurality of sensing areas, and uses these sensing areas to receive an input pattern, and the input pattern corresponds to at least part of these sensing areas. That is to use these sensing areas to record the position of the input pattern, so as to perform comparison according to the position. And according to the part of the sensing area corresponding to the input pattern, a plurality of sensing signals are generated, so as to compare these sensing signals with the sensing signals of the preset pattern. The input interface 101 is, for example, a touch panel or an electronic dot matrix panel.

In addition, the size of the sensing area and the number of sensing areas can be determined according to user requirements. For example, the input interface 101 of the same size can be configured with an aspect ratio of 3:3 (i.e. 9 sensing areas) or an aspect ratio of 5:6 (i.e. 30 sensing areas) according to different requirements. Of course , on the input interface 101 of the same size, if the number of sensing regions is larger, the range of each sensing region will be smaller, and vice versa. However, the present invention does not limit its scope.

The storage unit 103 is coupled to the processing unit 105 and is used for storing a database, and the database includes preset patterns, and the preset patterns are used for comparison with the input patterns. For example, in the general process of setting passwords, a set of passwords will be stored first for subsequent comparison. Similarly, the preset pattern here is also similar to the general process of setting a password, and the preset pattern must be stored in the storage unit 103 first, so that it can be compared with subsequent input patterns. In addition, in the storage unit 103 , a buffer memory (not shown) may be further provided for storing the received input patterns.

The processing unit 105 is adapted to determine whether the input pattern matches the preset pattern, so that the control unit 120 is turned on. In other words, the sensing signal of the input pattern is compared with the sensing signal of the preset pattern to determine whether it is within the error range. If within the error range, the control unit 120 is turned on.

For example, FIG. 2 is a schematic diagram of a notebook computer according to an embodiment of the present invention. Please refer to FIG. 2 . In this embodiment, a simple input pattern is used to open the front cover of the notebook computer 200 . In this embodiment, the front cover of the notebook computer 200 is configured with an input interface 210 (such as an electronic dot matrix board), and the input interface 210 is provided with a plurality of sensing areas (ie, grids on the input interface 210 ). Thus, a simple input pattern such as a "smiley face" can be drawn on these sensing areas.

After the input interface 210 receives the input pattern input by the user, for example, the processing unit 105 in FIG. 1 will determine whether the input pattern matches the stored preset pattern. When the input pattern matches the preset pattern, the processing unit 105 can operate the microcomputer magnetic lock (that is, the control unit 120 in FIG. 1 ) that opens the front cover of the notebook computer 200 .

In another optional embodiment, before entering the operating system of the notebook computer 200, another group of input patterns (certainly also can be the same as the input patterns for opening the front cover) can be set, and the input interface 210 is used to receive the input patterns to solve the problem. Unlock the software lock to enter the operating system. However, this embodiment is only for convenience of description, and the present invention does not limit its application scope.

In the following, the electronic device 100 of the foregoing embodiments is combined to further introduce the unlocking method of the present invention. Fig. 3 is a flowchart of an unlocking method according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 3, first, step S310 is to provide a plurality of sensing areas on the input interface 101, such as the grid on the input interface 210 in FIG. On which parts the position of the input pattern is located, so that the input pattern drawn later can conform to the preset pattern.

Next, step S320 allows the user to draw an input pattern in the sensing area through the input interface 101 , and the input pattern corresponds to at least part of these sensing areas, and generates a plurality of sensing signals. In other words, the input pattern is drawn on the input interface 101 by touching (for example, using a finger to draw an input pattern on the input interface 101), and the sensing area is used to sense the input pattern via the touch on the input interface 101. The pressure generated by the method, and the position where the pressure stays on the input interface 101 to generate a sensing signal.

Before using the lock of the electronic device 100 , it is necessary to set a preset pattern into the database, which is similar to setting a password. Firstly, the input interface 101 is used to receive a preset pattern corresponding to at least part of the sensing regions, and generate a plurality of sensing signals. In other words, these sensing signals are generated by the sensing area corresponding to the preset pattern, and are used to record the shape and position of the preset pattern, so that they can be judged through the comparison mechanism. Then these sensing signals are stored in the database of the storage unit 103 .

In addition, the user can also set a reminder message to remind the setting of the default pattern. Then, in step S330 , after receiving the input pattern through the input interface 101 , according to these sensing signals, it is judged whether the input pattern matches the preset pattern. Before drawing the input pattern, prompt information may be displayed on the input interface 101 to prompt the user to draw the input pattern.

Finally, step S340 is to use the processing unit 105 to control the electronic device 140 to unlock the lock when the input pattern matches the preset pattern. In other words, it is to compare whether the sensing signal of the input pattern and the sensing signal of the preset pattern are within the error range, and if it is within the error range, the input pattern is consistent with the preset pattern. For example, the comparison mechanism can be based on which sensing areas the preset pattern is located in. When the input pattern is also located in the same sensing area, then it can be judged whether the two match according to the drawn shape. However, this is only for convenience of description, and the present invention does not limit the comparison algorithm.

In some optional embodiments, the processing unit 105 can judge whether the user follows a preset sequence when inputting an input pattern through the sensing area on the input interface 210 to determine whether the input pattern is consistent with the preset pattern. match.

In summary, the present invention has at least the following advantages:

1. The front cover of the electronic device can be easily opened by drawing a simple input pattern instead of the opening method of the traditional clamshell electronic device, which adds to the fun.

2. Use a simple input pattern to replace the old digital password, which can improve the efficiency of remembering the password.

3. Patterns are more variable than numbers, so they are more confidential.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention, and anyone with ordinary knowledge in the technical field may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the claims.
