4 is a flow chart of a method for unlocking a screen according to a preferred embodiment of the present invention.

Referring to FIG. 1 , the electronic device 100 includes a touch screen 101 and a plurality of physical buttons 102 . When the electronic device 100 meets the preset lock screen condition, the touch screen 101 is automatically locked. The user needs to input the correct unlock password to unlock the touch screen 101. The electronic device 100 includes two working modes of an unlock mode and a crack mode. When the touch screen 101 is locked, the user can control the electronic device 100 to activate the unlock mode by operating the touch screen 101 or the corresponding physical button 102. In the unlock mode, the user can unlock the touch screen 101 by inputting an unlock password corresponding to the preset lock screen password, so that the electronic device 100 can be used normally. When the user forgets to unlock the password, the user can cause the electronic device 100 to activate the crack mode by pressing the corresponding physical button 102. When the user continuously inputs the wrong unlock password for a preset number of times, the electronic device 100 can automatically initiate the crack mode. In the crack mode, the user can input the correct verification information and erase the preset lock screen password, so that the electronic device 100 can be used normally. In the present embodiment, the electronic device 100 is a smart phone. A number of physical buttons 102 are switch buttons, volume buttons, and the like.

Referring to FIG. 2, the electronic device 100 further includes a storage unit 11, an interface providing unit 12, a detecting unit 13, a timing unit 14, a processing unit 15, and an alarm unit 16.

The storage unit 11 is configured to store a preset lock screen password, a crack verification information, and an anti-theft communication address. The crack verification information includes the associated verification questions and verification answers set by the user. The anti-theft communication address is the phone number or email address set by the user.

The interface providing unit 12 is configured to provide the unlocking interface 121 and the cracking interface to the user through the touch screen 101 under the control of the processing unit 15. As shown in FIG. 3, when the electronic device 100 activates the unlock mode, the interface providing unit 12 provides the unlocking interface 121 to the user through the touch screen 101 for the user to input the unlocking password. The unlock interface 121 includes a password area 1211 and a pointer 1212 that moves in response to the user's operation relative to the password area 1211. In the present embodiment, the password area 1211 is circular. The cipher area 1211 is pre-divided into a plurality of continuously distributed sector-shaped cipher units 1213. For example, the user regards the sector area corresponding to the 10° central angle in the password area 1211 as a cryptographic unit 1213, thereby equally dividing the cipher area 1211 into 36 cryptographic units 1213. Each cryptographic unit 1213 corresponds to a unique code. It can be understood that as the number of cryptographic units 1213 increases, the user is less likely to be peeked when entering the unlock password. In other embodiments, the shape of the cipher area 1211 may also be an ellipse, a square, an octagon, or the like. The cryptographic unit 1213 can also be a non-equalized area. The pointer 1212 has an initial position. This initial location is between two adjacent cryptographic units 1213. When the user clicks and drags the pointer 1212 on the touch screen 101 by a finger or a stylus, the pointer 1212 can rotate clockwise or counterclockwise around the center of the cipher area 1211. When the electronic device 100 activates the crack mode, the interface providing unit 12 provides a crack interface to the user through the touch screen 101. The crack interface is used for the user to input the crack verification information.

The detecting unit 13 is configured to detect an operation performed by the user through the touch screen 101 and the plurality of physical buttons 102, and send a corresponding detection signal to the processing unit 15. When the detecting unit 13 detects that the user controls the electronic device 100 to activate the unlock mode, for example, when the detecting unit 13 detects that the user presses the power button to cause the touch screen 101 to be illuminated by the dark screen state, the detecting unit 13 sends the first detecting signal to the processing. Unit 15. In the unlock mode, the detecting unit 13 is further configured to detect the position of the pointer 1212 when the user moves the pointer 1212 to determine the cryptographic unit 1213 indicated by the pointer 1212. When the detecting unit 13 detects that the user control electronic device 100 initiates the crack mode, the detecting unit transmits the second detection signal to the processing unit 15. In the present embodiment, the user controls the electronic device 100 to activate the crack mode by pressing a combination of the specific physical buttons 102. The combination of the physical keys 102 can be a combination of the default or user-defined physical keys 102 of the electronic device 100.

The timing unit 14 is operative to calculate the dwell time of the pointer 1212 within the cryptographic unit 1213 it indicates, and to transmit a timing signal to the processing unit 15 when the dwell time reaches a predetermined time period.

The processing unit 15 is configured to provide the unlocking interface 121 to the user through the touch screen 101 in response to the first detection signal control interface providing unit 12 . The processing unit 15 is further configured to respond to the code of the cryptographic unit 1213 indicated by the timing signal acquisition pointer 1212 of the timing unit 14 as a one-bit unlock password and return the pointer 1212 to the initial position. The processing unit 15 is further configured to determine whether the number of bits of the acquired unlock password is the same as the number of bits of the preset lock screen password. When the number of acquired unlocking passwords is the same as the number of the preset lock screen passwords, the processing unit 15 compares whether the obtained unlocking passwords are the same as the preset lock screen passwords. If the unlocking password is the same as the preset lock screen password, the processing unit 15 controls the interface providing unit 12 to provide the unlocked interface to the user through the touch screen 101. If the unlock password is different from the preset lock screen password, the processing unit 15 further determines whether the number of times the unlock password is continuously input incorrectly reaches a preset number of times. If the number of times the unlock password is continuously input incorrectly does not reach the preset number of times, the processing unit 15 controls the interface providing unit 12 to re-provide the unlocking interface 121 to the touch screen 101. If the number of consecutive input errors of the unlock password has reached the preset number of times, the processing unit 15 controls the electronic device 100 to enter the crack mode.

The processing unit 15 is further configured to respond to the second detection signal control interface providing unit 12 to provide a crack interface to the user through the touch screen 101 for the user to input the crack verification information. The processing unit 15 is further configured to determine whether the crack verification information input by the user is correct. If the crack verification information input by the user is correct, the processing unit 15 erases the preset lock screen password and the recorded unlock password continuously to input the error number, so that the user normally uses the electronic device 100. If the crack verification information input by the user is incorrect, the processing unit 15 sends an alarm signal to the alarm unit 16.

The alarm unit 16 is configured to acquire current location information of the electronic device 100 in response to the alarm signal, and send the current location information to a preset anti-theft communication address. In the embodiment, the alarm unit 16 sends the current location information of the electronic device 100 to a preset phone number by means of a short message, or sends the current location information of the electronic device 100 to a preset email address by means of an email. . In other embodiments, the alarm unit 16 may also acquire information about the current user such as images, sounds, and fingerprints of the current user of the electronic device 100, and send the information of the current user to a preset anti-theft communication address.

In other embodiments, the unlocking interface 121 may also not include the pointer 1212. The user can directly click the corresponding password unit 1213 in the password area 1211 with a finger or a stylus to input the unlock password.

Please refer to FIG. 4 , which is a screen unlocking method applied to the electronic device 100 . The screen unlocking method includes the following steps:

In step S501, when the electronic device 100 meets the preset lock screen condition, the touch screen 101 is automatically locked.

In step S502, the unlocking interface 121 is provided to the touch screen 101 according to the unlocking operation of the user. The unlock interface 121 includes a password area 1211 and a pointer 1212 that moves in response to the user's operation relative to the password area 1211. The cipher area 1211 is pre-divided into a plurality of cipher units 1213 corresponding to a unique code. In the present embodiment, the password area 1211 is circular. The cipher area 1211 is previously divided into a plurality of sector-shaped cipher units 1213. For example, the user regards the sector area corresponding to the 10° central angle in the password area 1211 as a cryptographic unit 1213, thereby equally dividing the cipher area 1211 into 36 cryptographic units 1213. Each cryptographic unit 1213 corresponds to a unique code. The pointer 1212 has an initial position. This initial location is between two adjacent cryptographic units 1213. When the user clicks and drags the pointer 1212 on the touch screen 101 by a finger or a stylus, the pointer 1212 can rotate clockwise or counterclockwise around the center of the cipher area 1211.

In step S503, the cryptographic unit 1213 indicated by the pointer 1212 in response to the user's operation moving relative to the cipher area 1211 is detected.

Step S504, calculating the dwell time of the pointer 1212 within the cipher unit 1213 indicated therein.

Step S505, determining whether the dwell time reaches a preset time period. If the dwell time has not reached the preset time period, then return to step S503. If the dwell time has reached the preset time period, the process proceeds to step S506.

In step S506, the code corresponding to the cryptographic unit 1213 is acquired as a one-bit unlock password, and the pointer 1212 is returned to the initial position.

Step S507, determining whether the number of bits of the acquired unlocking password reaches the number of bits of the preset lock screen password. If the number of bits of the acquired unlock password does not reach the number of bits of the preset lock screen password, then return to step S503. If the number of bits of the acquired unlock password has reached the number of bits of the preset lock screen password, then step S508 is reached.

Step S508, determining whether the acquired unlock password is the same as the preset lock screen password. If the unlock password is the same as the preset lock screen password, the process proceeds to step S509. If the unlock password is different from the preset lock screen password, the process proceeds to step S510.

In step S509, the locking of the touch screen 101 is released.

In step S510, it is determined whether the number of consecutive input errors of the unlock password reaches a preset number of times. If the number of consecutive input errors of the unlocking password does not reach the preset number of times, the process returns to step S502; if the number of consecutive errors of the unlocking password has reached the preset number of times, the process proceeds to step S511.

In step S511, the electronic device 100 is caused to enter the crack mode.

Step S512, providing a crack interface to the touch screen 101 according to the user's operation, and waiting for the user to input the crack verification information.

In step S513, it is determined whether the crack verification information input by the user is correct. If the crack verification information input by the user is correct, the process proceeds to step S514. If the crack verification information input by the user is incorrect, the process proceeds to step S515.

Step S514, erasing the preset lock screen password and the recorded unlock password continuously input the number of errors.

Step S515, the current location information of the acquiring electronic device 100 is sent to a preset anti-theft communication address.

In the above electronic device 100 and its screen unlocking method, when the touch screen 101 needs to be unlocked, the user may select the plurality of continuously distributed cryptographic units 1213 in a predetermined order to input the unlocking password. Compared with the existing four- to six-digit digital combination password, the plurality of cryptographic units 1213 are continuously distributed, and the user is not easy to be peeked when inputting the password, thereby reducing the probability that the lock screen password is leaked. In addition, when the electronic device 100 is lost, by adding the crack verification information, it is possible to prevent others from erasing the lock screen password preset by the user through the crack mode of the electronic device 100, thereby improving the security of the lock screen password.
