Description

Input password method for electronic device

The invention relates to an input password method for an electronic device, in particular to an input password method for tapping an electronic device surface instead of an electronic device for inputting a password by using a keyboard or a touch screen.

With the development of information technology, processor-based electronic devices, such as a wide variety of electronic devices, have been widely used by businesses and individuals. Traditionally, in order to protect personal privacy, an electronic device performs an identity authentication process at boot time.

The general electronic device allows the user to use the locking interface provided by the operating system to prevent others from booting up before starting the machine. Users need to enter the correct password through the keyboard or touch screen after locking the interface to boot and use this electronic device. However, the traditional way of entering a password is very easy for others to obtain the user's password, and the password is leaked. And the password is usually composed of letters, digits and symbols; if the combination of passwords is too simple, it is easy to be deciphered. If the combination of passwords is too complicated, it is not conducive to memory.

In addition, some manufacturers have developed mechanical anti-theft locks for portable electronic devices such as notebook computers. However, the mechanical anti-theft lock not only requires extra purchase but also is cumbersome; if it is attached with a chain-type anti-theft lock, it cannot be used in a place where there is no table leg, and it is inconvenient.

In order to solve the above problems, the present invention provides an input password method for an electronic device, which is applicable to an electronic device, wherein the electronic device includes a plurality of surface areas. The method of inputting a password for an electronic device includes the following steps. Receiving a plurality of detection signals from at least two vibration detectors, wherein the detection signals form a detection sequence, and the vibration detectors are disposed on different surface areas. The detection sequence is compared with an unlock sequence and a comparison result is generated. When the comparison result is the same, a power supply circuit that supplies power to the electronic device is activated to activate the electronic device.

The surface area may be a display backplane of the electronic device, a display side panel, a keyboard side panel, a touch panel or a main cabinet side panel. The shock detector can be a ball switch, a piezoelectric piece or an accelerometer.

According to an embodiment, the unlocking sequence may include a plurality of consecutive unlocking codes, and the unlocking codes in the unlocking sequence sequentially correspond to the detecting signals in the detecting sequence. The "step of detecting the sequence and unlocking the sequence and generating the comparison result" may include the following steps. The corresponding detection signals and unlock codes of each group are compared in sequence. When the corresponding detection signal and unlock code of each group are the same, the comparison result is set to be the same. When the detection signal corresponding to any group is different from the unlock code, the comparison result is inconsistent.

In addition, before the step of "receiving the detection signal from the at least two vibration detectors", the input password method of the electronic device may further include the step of "execution of a setting procedure when receiving a setting instruction". The setting procedure can include the following steps. A plurality of setting signals are received from the at least two vibration detectors, wherein the setting signals form a set sequence, and the vibration detectors are disposed in different surface areas. The set sequence is stored as an unlock sequence, and these set signals are sequentially stored as consecutive unlock codes.

According to another embodiment, there may be a detection interval between every two adjacent detection signals. The unlocking sequence may include a plurality of consecutive unlocking codes, and an unlocking interval between each two adjacent unlocking codes. The unlocking codes in the unlocking sequence are sequentially corresponding to the detecting signals in the detecting sequence, and the unlocking intervals in the unlocking sequence are sequentially corresponding to the detecting intervals in the detecting sequence.

The steps of "aligning the detection sequence with the unlock sequence and generating the comparison result" may include the following steps. The corresponding detection signals and unlock codes of each group are sequentially compared, and the corresponding detection interval and unlock interval of each group are sequentially compared. When the corresponding detection signal and the unlocking code are the same for each group, and the corresponding detection interval and unlocking interval are the same for each group, the comparison result is set to be consistent. When the detection signal corresponding to any group is different from the unlock code, or the detection interval corresponding to any group is different from the unlock interval, the comparison result is inconsistent.

According to still another embodiment, the electronic device can have a sound receiver, and the sound receiver can generate a plurality of detected audio signals corresponding to the detection signals. When the comparison result is consistent, and the frequency of the detected audio matches the frequency of the plurality of consecutive unlocked audios, the power supply circuit that supplies power to the electronic device is activated to activate the electronic device.

In addition, before the step of "receiving the detection signal from the at least two vibration detectors", the input password method of the electronic device may further include the step of "execution of a setting procedure when receiving a setting instruction". The setting procedure can include the following steps. Receiving a plurality of setting signals from at least two vibration detectors and receiving a pair from the sound receiver A plurality of setting audios of the setting signals should be set; wherein the setting signals form a setting sequence, and the vibration detectors are disposed in different surface areas. Save the set sequence as an unlock sequence. Save these settings as these unlocked audio.

According to different embodiments, after the power supply circuit is activated, the input password method of the electronic device may perform different booting modes. In an embodiment, the step of "starting the supply of power to the power supply circuit of the electronic device to activate the electronic device" may include the following steps. A power supply circuit that supplies power to the electronic device is activated.

A power supply circuit that supplies power to the electronic device is activated. When receiving a power-on trigger signal, the operating system of the electronic device is loaded, and the electronic device is activated according to the operating system.

In summary, the input password method of the electronic device can detect the back tapping of the surface area through multiple shock detectors, and generate a detection sequence according to the situation where the surface area is tapped, and then determine whether to start. Power supply circuit. Since the input password method of the electronic device can use the content, the sequence, the interval time and the audio generated during the tapping of the detection sequence as the password, the password has a high password complexity. In contrast, the user only needs to memorize a simple tapping method without having to memorize the complicated text password content. If the detection sequence is inconsistent with the unlock sequence, the power supply circuit will not be turned on, and the electronic device will not be able to be turned on, so that the security can be ensured from the hardware.

The detailed features and advantages of the present invention are set forth in the Detailed Description of the Detailed Description of the <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> </ RTI> <RTIgt; The objects and advantages associated with the present invention can be readily understood by those skilled in the art.

The invention provides an input password method for an electronic device, which is suitable for booting an electronic device. The electronic device includes a plurality of surface areas, and the user can input a password to unlock and turn on the device by tapping the surface area instead of inputting a password method of the electronic device that inputs the password by using a keyboard or a touch screen.

Please refer to "1A", "1B" and "1C" and the schematic diagrams of the electronic devices of different embodiments. The electronic device 20 can be, for example, a notebook computer, a desktop computer, a tablet computer, or a smart phone, and the electronic device 20 includes a plurality of surface regions 22.

For example, when the electronic device 20 is a notebook computer, the surface area 22 can be a display back panel of the electronic device 20, a display side panel, a keyboard side panel, or a touch panel. When the electronic device 20 is a desktop computer, the surface area 22 can be a main cabinet side panel. Preferably, surface area 22 is not a button of a keyboard.

A vibration detector 24 can be disposed on each of the surface regions 22 to detect whether the surface region 22 is ready for tapping. According to an embodiment, at least two surface areas 22 are provided with a shock detector 24 to increase password complexity. The shock detector 24 can be, for example, a ball open A piezoelectric sheet or an accelerometer can be disposed at any suitable location on the surface region 22.

Traditionally, when the user wants to turn on the computer, the electronic device 20 needs to wait for the operating system (OS) to input the account password through the login screen provided by the operating system. After the account password is verified, the electronic device 20 will continue to boot. Actions. However, the electronic device 20 still has a very small number of components operating without being turned on, such as a keyboard controller (KBC). The input password method of the electronic device provided by the present invention can be executed by the KBC before a booting process has been executed and the system is not loaded yet.

Please refer to FIG. 2, which is a schematic flowchart of a method for inputting a password for an electronic device according to an embodiment.

In order to boot, the user can first press a power button of the electronic device 20, and the power button will send a power-on trigger signal accordingly. After receiving the power-on trigger signal, the KBC receives a plurality of detection signals from the at least two motion detectors 24, wherein the detection signals form a detection sequence (step S100). The motion detectors 24 are disposed in different surface areas 22, and the KBC can receive multiple detection signals from a single motion detector 24. According to an embodiment, each of the motion detectors 24 has an identification code (ID). When the signal is detected, the vibration detector 24 informs the KBC, and the KBC can record the identification code of the vibration detector 24 that sends the detection signal as the content of the detection signal; and the KBC can follow these detections. The order in which the signals are detected will be recorded by the corresponding identification code. Detection sequence.

Then, the KBC compares the detection sequence with an unlocking sequence, and generates a comparison result (step S200), and then determines whether the comparison result is consistent (step S300). When the comparison result is the same, the KBC starts a power supply circuit that supplies power to the electronic device 20 to activate the electronic device 20 (step S400). On the other hand, when the comparison result is inconsistent, the process returns to step S100 to wait for the correct detection sequence to be received.

The power supply circuit may be a hardware circuit in the electronic device 20, such as a switching circuit connected to a power supply. When the detection sequence consistent with the unlock sequence is not received, the power supply circuit is not activated; and when the power supply circuit is not activated, the electronic device 20 cannot obtain power on from the power supply, thereby ensuring that the data in the electronic device 20 is not Will be stolen.

Please refer to "FIG. 3", which is a schematic diagram of the process of step S200 of an embodiment.

The KBC can read the unlock sequence from a memory, and the unlock sequence can include a plurality of consecutive unlock codes, each of which can correspond to the identification code of one of the motion detectors 24. The memory storing the unlock sequence may be, for example, an Electronically Erasable Programmable Read-Only Memory (EEPROM) or a flash memory, and the memory may be in the electronic The device 20 is used after performing Power On Self Test (POST). In addition, the unlocking sequence can also be stored in the same memory as a basic input/output system (BIOS) of the electronic device 20.

After the KBC obtains the detection sequence and the unlocking sequence, the corresponding detection signals and the unlocking codes of each group are sequentially compared (step S211), and then it is determined whether the content and sequence of the corresponding detection signals and unlocking codes of each group are the same. (Step S212). When the content and sequence of the corresponding detection signal and the unlock code of each group are the same, the KBC can set the comparison result to be consistent (step S213). On the other hand, when the content or sequence of the detection signal corresponding to any one of the groups is different from the unlock code, the KBC setting comparison result is inconsistent (step S214).

For example, it is assumed that the electronic device 20 is a notebook computer, and a vibration detector 24 is disposed on the back panel of the display, the side panel on the left side of the keyboard, and the touch panel, and the identification codes of the three vibration detectors 24 are respectively configured. It is 1, 2, and 3 respectively; and it is assumed that the unlock sequence has 4 unlock codes, and the content of the unlock sequence is "1123". If the user taps twice on the back panel of the display, taps once on the left side of the keyboard, and taps once on the touchpad, a detection sequence with the content "1123" is generated. The KBC compares the corresponding detection signal and the unlock code one by one and judges that the content and the order are exactly the same, so the comparison result is set to be consistent. In this way, the KBC can determine whether it can be unlocked and turned on according to the number and timing of the plurality of surface areas 22 being tapped.

According to another embodiment, in addition to the number and order in which the plurality of surface regions 22 are tapped, the KBC may determine based on the frequency at which the tapping is performed to increase the cryptographic complexity. Please refer to FIG. 4, which is a schematic flowchart of step S200 of another embodiment.

In this embodiment, there is a detection between every two adjacent detection signals. The interval between each two adjacent unlock codes has an unlocking interval, and the unlocking intervals in the unlocking sequence are sequentially corresponding to the detecting intervals in the detecting sequence. The unit of the detection interval and the unlock interval may be, for example, a second or a cycle of KBC. The KBC sequentially compares the corresponding detection signals and unlock codes of each group, and sequentially compares the corresponding detection intervals and unlocking intervals of each group (step S221). The KBC further determines whether the corresponding detection signal and the unlocking code of each group are the same, and the corresponding detection interval and the unlocking interval of each group are the same (step S222).

When the content and sequence of the corresponding detection signal and the unlocking code of each group are the same, and the detection interval and the unlocking interval length of each group are the same, the KBC setting comparison result is consistent (step S223). On the other hand, when the content or sequence of the detection signal and the unlock code of any group are different, or the detection interval of the corresponding group is different from the length of the unlocking interval, the KBC setting comparison result is inconsistent (step S224).

In addition, the above unlocking sequence and the unlocking interval may be preset or may be set by the user. According to different implementation examples, the setting program can be integrated into the BIOS setting menu, or can be implemented as an application for the user to set after entering the operating system. The following description assumes that the setting program is integrated in the BIOS setup menu.

Please refer to FIG. 5, which is a schematic flowchart of a method for inputting a password for an electronic device according to an embodiment. After receiving the power-on trigger signal, the KBC may first determine whether to receive a setting command (step S500). When receiving a set command At this time, the KBC can execute a setting procedure (step S600) to reset the retrieval sequence. When the setting command is not received, the KBC can directly go to step S100. In more detail, when the user wants to change the unlock sequence, he can type the hotkey to open the BIOS setup menu at boot time, and enter the setup command in the setup menu to start the setup procedure.

Next, please refer to "FIG. 6", which is a schematic flow chart of a step setting procedure of an embodiment.

After the setting program is started, the KBC can receive a plurality of setting signals from the at least two vibration detectors 24, wherein the setting signals form a setting sequence (step S611), and the vibration detectors 24 are disposed on different surface areas 22. The KBC can store the set sequence as a new unlock sequence and sequentially store the set signals as new consecutive unlock codes (step S612). After the setting procedure is executed, the process returns to step S100 to determine whether a detection sequence that is consistent with the new unlocking sequence is received.

According to yet another embodiment. The KBC can also be judged based on the frequency of the sound generated when the surface area 22 is struck. In this embodiment, the electronic device 20 can have a microphone, such as a microphone. The radio can generate a plurality of detected audio corresponding to the detection signals when the user taps the surface area 22. In step S200, the KBC determines whether the frequency of the detected signals and the sequence of the unlocking codes are the same, and whether the frequency of the detected audio signals is consistent with the frequency of the plurality of consecutive unlocking audio signals. When the comparison result is consistent, and the frequency of these detected audio is consistent with the frequency of consecutive multiple unlocked audio At this time, the power supply circuit is activated to activate the electronic device 20. Since the pitch generated by tapping different surface areas 22 in different ways is different, this method can increase the complexity of the password.

Similarly, in addition to setting a new unlock sequence, the setup program can also set a new unlocked audio, as shown in Figure 7.

After the setting program is started, the KBC can receive a plurality of setting signals from the at least two vibration detectors 24, and receive a plurality of setting signals corresponding to the setting signals from the sound receiver, and the setting signals form a setting sequence (step S621). The KBC can then store the set sequence as an unlock sequence (step S612) and store the set audio as the unlocked audio corresponding to the unlock sequence (step S612).

In addition, the function of analyzing the frequency of detecting audio and the function of comparing frequencies can be integrated with KBC, or can be integrated into a function chip or program. This allows the BIOS to simultaneously initiate the set unlock sequence and audio-related functions, while avoiding the need for the BIOS to additionally enable or disable audio-related functions.

In short, the KBC can detect whether a plurality of surface areas 22 are tapped to determine whether to activate the power supply circuit; and the user can use the program to change the unlock sequence by itself. According to different implementation examples, the KBC starts the power supply circuit and can directly enter the operating system or only make the power supply operate normally. It should be noted that when the comparison detection interval or the frequency of detecting the audio is consistent with the unlock interval or the frequency of unlocking the audio, an allowable error can be set to increase the convenience of use.

Please refer to "Figure 8" first, which is a flow of step S400 of an embodiment. Schematic diagram. When the comparison result is identical, the KBC starts the power supply circuit that supplies power to the electronic device 20 (step S411). The KBC can then be directly loaded into the operating system of the electronic device 20, and the electronic device 20 is activated in accordance with the operating system (step S412).

Please refer to FIG. 9 again, which is a schematic flowchart of step S400 of another embodiment. When the comparison result is the same, the KBC starts the power supply circuit that supplies power to the electronic device 20 (step S421). At this point, the KBC only makes the power supply work normally. If the user really wants to turn it on, press the power button again. The KBC can then determine whether to receive the power-on trigger signal from the power button again for a predetermined period of time (step S422). The predetermined time may be, for example but not limited to, 10 seconds. When the power-on trigger signal is received within the predetermined period, the KBC is loaded into the operating system of the electronic device 20, and the electronic device 20 is activated in accordance with the operating system (step S423). On the other hand, when the power-on trigger signal is not received within the predetermined period, the process returns to step S100.

The input password method of the electronic device can be used in addition to the case where the electronic device 20 replies from the sleep mode or the screen protection state before the booting process can be performed. According to an embodiment, when the electronic device 20 is in the sleep mode or the screen protection state, the user needs to use the input password method of the electronic device to unlock the electronic device 20 before continuing to use.

In addition, the input password method of the electronic device can also be used in various data decryption programs. For example, the user can set an unlock sequence or unlock the audio for at least one electronic file; if it is necessary to open, access or decrypt the electronic file, The unlocking method is performed by using the input password method of the electronic device.

In summary, the input password method of the electronic device can detect the back tapping of the surface area, and generate a detection sequence according to the situation of being tapped, and then determine whether to unlock. Since the content, sequence, interval time and even the audio generated during the tapping can be used as a combination of passwords, it has a high password complexity. In contrast, the user only needs to memorize a simple tapping method without having to memorize the complicated text password content. Therefore, the input password method of the electronic device can provide a simple but more reliable encryption and decryption method by the user.
