The security device 100 may perform an action of determining whether to release the locked state of the lock 110 based on the user's eye opening and closing state based on the procedure shown in FIG. 2 .

FIG. 2 is a flow chart of the steps of the password input method based on the opening and closing state of the eyes according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 at the same time. First, the image sequence IS is captured by the imaging unit 120 (step S200 ). Afterwards, the image sequence IS is analyzed by the processing unit 130 , so as to obtain the eye image information of the user's eye area in the image sequence IS (step S210 ). Next, the processing unit 130 detects the user's eye opening and closing state (including the eye opening state and the eye closing state) based on the eye image information (step S220 ).

After detecting the user's eye opening and closing states, the processing unit 130 will convert the detected multiple eye opening states and eye closing states into eye opening and closing state codes (step S230), and judge the eye state accordingly. Whether the opening and closing state code matches the preset unlock password (step S240). The preset unlocking password mentioned here may be, for example, conditions such as the number of blinks, the frequency of occurrence and/or the duration of eye opening or closing (further examples will be described in subsequent embodiments). Based on this, the processing unit 130 can determine whether to release the locked state of the lock 110 according to the result of the above determination (step S250 ).

The following uses the embodiment of FIG. 3 to further illustrate the specific steps of unlocking based on the eye opening and closing state. Wherein, FIG. 3 is a flow chart of the steps of the password input method based on the state of opening and closing of eyes according to another embodiment of the present invention. Here, the following embodiments are described in conjunction with the hardware architecture of the security device 100 in the embodiment shown in FIG. 1 , but the password input method based on the eye opening and closing state can be applied to the hardware architecture of any type of security device. , the present invention is not limited thereto.

Please refer to FIG. 3 first. In the password input method of this embodiment, the image sequence IS will also be captured by the imaging unit 120 (step S300), so that the processing unit 130 can obtain the image sequence IS by analyzing the image sequence IS. , eye image information of the user's eye region (step S310 ).

Afterwards, the processing unit 130 will search for eye objects in the eye area based on the eye image information (step S320), and judge whether the eye objects are in an open-eye state or a closed-eye state according to the size of the eye object (step S330 ). Next, the processing unit 130 detects the eye opening and closing state of the user per unit time according to the eye opening/closing state of the eye object, and accordingly converts the detected multiple eye opening states and eye closing states Convert to eye opening and closing state code (step S340).

After obtaining the user's eye opening and closing state code, the processing unit 130 will compare the obtained eye opening and closing state code with the preset unlock password to determine whether the user's eye opening and closing state code conforms to the preset code. Unlock the password (step S350). When the lock 110 is in the locked state, if the determination in step S350 is yes, the processing unit 130 will release the lock state of the lock 110 (that is, the lock 110 is switched to the unlocked state) (step S360); otherwise, if the determination is no, Then the processing unit 130 maintains the locked state of the lock 110 (step S370 ). From another point of view, if the lock 110 is already in the unlocked state, no matter whether the determination result of step S350 is yes, the lock 110 will remain in the unlocked state. It is worth mentioning here that, in an exemplary embodiment, the user can also make a set of continuous eye movements when the lock 110 is unlocked, so as to utilize the eye corresponding to the continuous blinking movements. The internal opening and closing state coding is used to define the preset unlocking password. Certainly, the preset unlocking password may also be predefined by a designer and stored in a storage unit (not shown) of the security device 100 , and the present invention is not limited thereto.

It is worth mentioning here that, in an exemplary embodiment, after the eye object is searched (step S320 ), this embodiment can first identify the biometric information (such as iris or retina) of the user's eye object. information) to confirm the identity of the user. If the identity of the user is correct, the subsequent steps S330-S370 are further executed. If not, then stop/reject the subsequent eye movement recognition steps.

4A, FIG. 5, FIG. 6A-6E and FIG. 7A-7E to illustrate the above-mentioned step S330 of judging the state of the eye object, step S340 of converting the code of the eye opening and closing state, and judging the eye opening and closing. The specific steps of step S350 of whether the status meets the preset unlocking password.

FIG. 4A is a flow chart of steps for determining the state of the eye region according to an embodiment of FIG. 3 . 4B and 4C are schematic diagrams of judging the state of the eye region according to an embodiment of FIG. 3 . Please refer to FIG. 4A to FIG. 4C together. After the processing unit 130 searches for the eye object 410 in the eye region ER, the processing unit 130 can perform image processing on the eye image information to obtain a clear indication of the eye object boundary. image information, so that the processing unit 130 can calculate the size of the eye object 410 (including the height and width of the eye object 410 ) according to the image information (step S332 ).

For example, the processing unit 130 can obtain an enhanced image by adjusting the contrast of the eye image information (for example, adjusting the gain value (gain) and the offset value (offset)), and then sequentially perform noise removal, The image of the eye object 410 as shown in FIG. 4B is obtained through processing such as edge sharpening, binarization, and edge sharpening again.

After the eye object 410 is detected and the size of the eye object 410 is calculated, the processing unit 130 will determine whether the height of the eye object 410 is less than a height threshold (for example, a height threshold) according to the size of the eye object 410 is within 15-17 pixels), and whether the width of the eye object 410 is greater than the width threshold (for example, the width threshold is within 70-90 pixels) (step S334 ). Wherein, when the processing unit 130 detects that the height of the eye object 410 is less than the height threshold and the width of the eye object is greater than the width threshold, the processing unit 130 will determine that the eye region ER is currently in the closed-eye state (as shown in FIG. 4B lower half) (step S336); otherwise, if the processing unit 130 detects that the eye object 410 does not meet at least one of the above conditions, the processing unit 130 will determine that the eye region ER is currently in an eye-open state ( As shown in the upper half of Fig. 4B) (step S338).

As shown in FIG. 4B , the height of the eye object 410 can be, for example, the distance from the upper apex to the lower apex of the eye frame boundary (such as height L1, L2), and the width of the eye object 410 can be For example, it is the distance from the left vertex to the right vertex of the boundary of the eye frame (such as width W1, W2), but the present invention is not limited thereto. In other embodiments, the processing unit 130 can also define the feature points on the eye object 410 as the basis for calculating the height and width.

It is also worth mentioning that although the present embodiment shows that the eye region ER is identified as the eye-opening state or the eye-closing state according to the image of a single eye, the present invention is not limited thereto. In other embodiments, the open/closed state of the eye region ER can also be determined according to the images of the left and right eyes of the user (for example, it is determined that the eye region ER is in the closed state only when the left and right eyes are detected to be closed at the same time. ). Alternatively, the open/closed state of the corresponding left eye region (for example: the left half of the eye region ER) and the right eye region (for example: the right half of the eye region ER) are independently defined according to the left and right eye images eye open/closed state.

After the processing unit 130 determines whether the eye object is in the eye-opening state or the eye-closing state, the processing unit may perform the step S340 of converting the code of the eye opening and closing state according to the step flow in FIG. 5 .

Please refer to FIG. 5 , after the processing unit 130 determines whether the eye area is in the open state or closed state, it will further detect the state of the eye object within a unit time (which can be defined by the designer) (step S341), And it is judged whether the eye region is in the eye-open state or the eye-close state within a unit time (step S342 ). If it is determined in step S342 that the eye region is in the eye-open state within a unit time, the processing unit 130 determines that the user has opened the eye, and generates a first code accordingly (step S343 ). On the contrary, if it is determined in step S342 that the eye region is in the eye-closed state within a unit time, the processing unit 130 determines that the user has closed the eyes, and generates a second code accordingly (step S344 ). Here, the first code is, for example, logic "1", and the second code is, for example, logic "0", but the present invention is not limited thereto. In other embodiments, the first code corresponding to the eye-opening state may also be a logic "0", and the second code corresponding to the eye-closing state may also be a logic "1".

The processing unit 130 will continuously obtain the user's multiple eye-opening states and eye-closing states within a preset period of time (which can be regarded as composed of multiple unit times), and calculate the user's multiple eye-opening states based on the multiple eye-opening states within the preset time. and the plurality of first and second codes generated by the eye-closed state are arranged in sequence to form an eye-opened-closed state code (step S345 ). Wherein, the processing unit 130 will successively perform the step S350 of comparing the eye opening and closing state code with the preset unlocking password, so as to determine whether the eye opening and closing state code obtained from the user's eye movements matches the preset unlocking password. . Below, the steps of FIG. 6A to FIG. 6E are combined with the encoding format of the eye opening and closing state encoding in FIG. 7A to FIG. 7E to illustrate the judgment methods under different preset unlocking passwords. Among them, the eye opening and closing state codes PUC and PUC' in FIG. 7A to FIG. 7E are sequentially converted by the processing unit 130 based on the open/closed state of the eye object in each unit time UT within the preset time PT. The resulting coding sequence (here, a 12-bit coding sequence is taken as an example, but the present invention is not limited thereto). In the eye opening and closing state codes PUC and PUC', the first code B1 generated based on the eye open state is marked with a logic "1", while the second code B2 generated based on the eye closed state is marked with a logic "0" ” mark, but the present invention is not limited thereto.

Please refer to FIG. 6A first. In this embodiment, the default unlock password is set to a specific number of blinks. In detail, in step S350 of this embodiment, the processing unit 130 defines the continuously generated first and second codes as blink codes (indicating that when the processing unit 130 continuously generates the first and second codes, the user blinks action) (step S351A), and count the number of blink codes in the eye opening and closing state codes (ie, the number of blinks of the user) (step S352A). Next, the processing unit 130 compares the number of blinks with a predetermined number of blinks, so as to determine whether the counted number of blinks is equal to the preset number of blinks (step S354A). Wherein, if the processing unit 130 determines that the number of blinks is equal to the preset number of blinks, then it is determined that the code of the user's eye opening and closing state conforms to the preset unlock password (step S356A), and proceed to step S360 to unlock the locked state of the lock 110; otherwise If the processing unit 130 determines that the number of blinks is not equal to the preset number of blinks, then it is determined that the user's eye opening and closing state code does not match the preset unlocking code (step S358A), and proceed to step S370 to maintain the locked state of the lock 110 .

For example, please refer to FIG. 6A and FIG. 7A together, assuming that the default number of blinks is set to 3. When the processing unit 130 obtains the eye opening and closing state code PUC composed of the code sequence "111011101011" according to the user's eye movement, the processing unit 130 will define the code "10" as a blink code BB, and Based on this, the number of times the blink code BB appears in the eye opening and closing state code PUC is counted. In the eye opening and closing state code PUC, the processing unit 130 will count the occurrence of the blink code BB 3 times (that is, the user blinks 3 times), so as to determine that the user's eye opening and closing state code PUC matches the preset unlock code , and release the locked state of the lock 110 .

On the other hand, when the processing unit 130 obtains the eye opening and closing state code PUC' composed of the code sequence of "111110111011" according to the user's eye movement, the processing unit 130 also first defines the code of "10" as A blink code BB, and count the number of times the blink code BB appears in the eye opening and closing state code PUC' accordingly. In the eye opening and closing state code PUC', since the processing unit 130 only counts the occurrence of the blink code BB twice (that is, the user blinks twice), it will determine the user's eye opening and closing state code PUC' If the preset unlock password is not met, the locked state of the lock 110 is maintained.

Here, the preset number of blinks (3 times) is just an example for convenience of description, and the present invention is not limited thereto. Furthermore, the preset number of blinks can be N times, and the value of N is a positive integer that can be selected by the designer.

Please refer to FIG. 6B , in this embodiment, the preset unlock password is set to a specific blink frequency range. In detail, in step S350 of this embodiment, the processing unit 130 defines the continuously generated first and second codes as blink codes (step S351B), and calculates the blink code in the eye opening and closing state codes. frequency (that is, the blinking frequency of the user) (step S352B). Next, the processing unit 130 determines whether the calculated blink rate is within a preset blink rate range (step S354B). Wherein, if the processing unit 130 determines that the blinking frequency is within the preset blinking frequency range, it determines that the user's eye opening and closing state code conforms to the preset unlocking password (step S356B), and proceeds to step S360 to unlock the lock 110 Conversely, if the processing unit 130 judges that the blink frequency is outside the preset blink frequency range, then it is determined that the user’s eye opening and closing state code does not match the preset unlock password (step S358B), and proceed to step S370 to maintain the lock 110 lock status.

For example, please refer to FIG. 6B and FIG. 7B together, assuming that the preset blink frequency range is set to 1.9˜2.1 seconds/blink times. When the processing unit 130 obtains the eye opening and closing state code PUC composed of the code sequence "110111011101" according to the user's eye movement, the processing unit 130 will define the code "10" as a blink code BB, and Based on this, the frequency/time interval of the blink code BB appearing in the eye opening and closing state code PUC is calculated. In the eye opening and closing state code PUC, the processing unit 130 will calculate the time interval between the first blink code BB and the second blink code BB as TD1, and the second blink code BB and the third blink code BB appear The time interval is TD2. Wherein, when the time interval TD1 and the time interval TD2 are both within 1.9-2.1 seconds (that is, the user blinks once at an interval of 1.9-2.1 seconds), the processing unit 130 will determine that the user's eyes The internal opening and closing state code PUC conforms to the preset unlocking password, and unlocks the locked state of the lock 110 .

On the other hand, when the processing unit 130 obtains the eye opening and closing state code PUC' composed of the code sequence of "110110111011" according to the user's eye movement, the processing unit 130 also first defines the code of "10" as A blink code BB, and the frequency of the blink code BB in the eye opening and closing state code PUC' is calculated accordingly. In the eye opening and closing state code PUC', the processing unit 130 will calculate the time interval between the first blink code BB and the second blink code BB as TD1', and the second blink code BB and the third blink code The time interval at which BB appears is TD2'. Wherein, when one of the time intervals TD1' and TD2' is outside the range of 1.9 to 2.1 seconds (such as the time interval TD1'), the processing unit 130 will determine that the user's eye opening and closing state code PUC' does not meet the requirements. The unlock password is preset, and the locked state of the lock 110 is maintained.

Here, the preset blink frequency range (1.9-2.1 seconds/blink times) is just an example for convenience of description, but the present invention is not limited thereto. Furthermore, the upper/lower limit of the preset blink frequency range can be selected by the designer, and can also be a specific frequency (for example, 2 seconds/blink times).

Please refer to FIG. 6C , in this embodiment, the preset unlocking password is set to a specific continuous eye-opening time. In detail, in step S350 of this embodiment, the processing unit 130 will calculate the time during which the first code corresponding to the eye-opening state in the eye opening and closing state codes appears continuously (that is, the continuous eye-opening time) (step S352C ). Next, the processing unit 130 determines whether the calculated eye-opening duration is within a preset eye-opening time range (step S354C). Wherein, if the processing unit 130 judges that the continuous eye-opening time is within the preset eye-opening time range, it determines that the user's eye opening and closing state code conforms to the preset unlocking password (step S356C), and proceeds to step S360 to unlock the lock 110; on the contrary, if the processing unit 130 determines that the continuous eye opening time is outside the preset eye opening time range, then it is determined that the user’s eye opening and closing state code does not conform to the preset unlocking password (step S358C), and continue Step S370 is performed to maintain the locked state of the lock 110 .

For example, referring to FIG. 6C and FIG. 7C together, it is assumed that the preset eye-opening time range is set to 9-11 seconds. When the processing unit 130 obtains the eye opening and closing state code PUC composed of the code sequence of "100111111011" according to the user's eye movements, the processing unit 130 will calculate the first code B1 (marked as "1") in the eye The maximum length of time COT that continuously appears in the opening and closing state code PUC. In the eye opening and closing state code PUC, the processing unit 130 calculates that the maximum time length COT of the first code B1 appearing continuously is about 6 unit times UT. Wherein, when the maximum time length COT is within 9-11 seconds (that is, the user keeps eyes open for 9-11 seconds), the processing unit 130 will determine that the user's eye opening and closing state code PUC matches the preset unlocking password, And the locked state of the lock 110 is released.

On the other hand, when the processing unit 130 obtains the eye opening and closing state code PUC' composed of the code sequence of "110111011110" according to the user's eye movement, the processing unit 130 will calculate the first code B1 in the eye opening and closing state code PUC'. The maximum length of time COT that appears continuously in the combined state code PUC'. In the eye opening and closing state code PUC', the processing unit 130 calculates that the maximum time length COT' of the first code B1 appearing continuously is about 4 unit times UT. Wherein, when the maximum time length COT' is outside the range of 9-11 seconds, the processing unit 130 will determine that the user's eye opening and closing state code PUC' does not match the preset unlocking code, and maintain the locked state of the lock 110 .

Here, the preset eye-opening time range (9-11 seconds) is just an example for convenience of description, but the present invention is not limited thereto. Furthermore, the upper/lower limit of the set eye-opening time range can be selected by the designer, or only the lower limit of the eye-opening time range is set without setting the upper limit (that is, as long as the user keeps opening the eyes beyond the set The lower limit of the set eye opening time range, that is, to determine that the corresponding eye opening and closing state code conforms to the preset unlock password).

Please refer to FIG. 6D , in this embodiment, the preset unlock password is set to a specific continuous eye-closed time. In detail, in step S350 of this embodiment, the processing unit 130 will calculate the time during which the second code corresponding to the eye-closed state in the eye opening and closing state codes appears continuously (that is, the continuous eye-closed time) (step S352D ). Next, the processing unit 130 determines whether the calculated continuous eye-closed time is within a preset eye-closed time range (step S354D). Wherein, if the processing unit 130 determines that the continuous eye-closing time is within the preset eye-closing time range, it determines that the user's eye opening and closing state code conforms to the preset unlocking password (step S356D), and proceeds to step S360 to unlock the lock 110; on the contrary, if the processing unit 130 determines that the continuous eye-closed time is outside the preset eye-closed time range, then it is determined that the user’s eye opening and closing state code does not match the preset unlock password (step S358D), and continue Step S370 is performed to maintain the locked state of the lock 110 .

For example, referring to FIG. 6D and FIG. 7D together, it is assumed that the preset eye-closing time range is set to 9-11 seconds. When the processing unit 130 obtains the eye opening and closing state code PUC composed of the code sequence "110110000001" according to the user's eye movements, the processing unit 130 will calculate the second code B2 (marked as "0") in the eye The maximum time length CCT that appears continuously in the PUC of the opening and closing state code. In the eye opening and closing state code PUC, the processing unit 130 calculates that the maximum time length CCT in which the second code B2 appears continuously is about 6 unit times UT. Wherein, when the maximum time length CCT is within 9-11 seconds (that is, the user keeps eyes closed for 9-11 seconds), the processing unit 130 will determine that the user's eye opening and closing state code PUC matches the preset unlock password, And the locked state of the lock 110 is released.

On the other hand, when the processing unit 130 obtains the eye opening and closing state code PUC' composed of the code sequence of "101100011011" according to the user's eye movement, the processing unit 130 will calculate the second code B2 in the eye opening and closing state code PUC'. The maximum time length CCT' that appears continuously in the combined state code PUC'. In the eye opening and closing state code PUC', the processing unit 130 calculates that the maximum time length CCT' of the second code B2 appearing continuously is about 3 unit times UT. Wherein, when the maximum time length COT' is outside the range of 9-11 seconds, the processing unit 130 will determine that the user's eye opening and closing state code PUC' does not match the preset unlocking code, and maintain the locked state of the lock 110 .

Here, the preset eye-closing time range (9-11 seconds) is just an example for convenience of description, but the present invention is not limited thereto. Furthermore, the upper/lower limit of the set eye-closing time range can be selected by the designer, or only the lower limit of the eye-closing time range can be set without setting the upper limit (that is, as long as the user continues to close the eyes for more than the set The lower limit of the set eye-closing time range is to determine that the corresponding eye opening and closing state code conforms to the preset unlock password).

Please refer to FIG. 6E , in this embodiment, the processing unit 130 determines whether to unlock or not by comparing whether the eye opening and closing state code is exactly the same as the preset unlock password. In detail, in step S350 of this embodiment, the processing unit 130 compares each bit of the eye opening and closing state code with the preset unlock password (step S352E). Next, the processing unit 130 judges whether each digit of the obtained eye opening and closing state code matches the preset unlocking password (step S354E). Wherein, if the processing unit 130 judges that each bit in the eye opening and closing state code matches the preset unlocking password, it determines that the user’s eye opening and closing state code matches the preset unlocking password (step S356E), and proceeds to the next step S360 to unlock the locked state of the lock 110; on the contrary, if the processing unit 130 judges that at least one of the codes of the eye opening and closing state does not conform to the preset unlocking password, then it is determined that the code of the user's eye opening and closing state does not conform to the preset Unlock the password (step S358E), and proceed to step S370 to maintain the locked state of the lock 110 .

For example, referring to FIG. 6E and FIG. 7E together, it is assumed that the default unlocking password is set as a code sequence composed of 8 digits “10101010”. When the processing unit 130 obtains the eye opening and closing state code PUC composed of the code sequence of "10101010" according to the user's eye movement, the processing unit 130 will convert each part of the obtained eye opening and closing state code PUC to Bits are compared with the preset unlock password. After comparison, the processing unit 130 will determine that each bit of the user's eye opening and closing state code PUC is the same as the preset unlocking password, so the processing unit 130 will immediately determine the user's eye opening and closing state code PUC Meet the preset unlock password, and release the locked state of the lock 110 .

On the other hand, when the processing unit 130 obtains the eye opening and closing state code PUC' composed of the code sequence of "11101010" according to the user's eye movement, the processing unit 130 will convert the obtained eye opening and closing state to Each digit of the encoded PUC' is compared with the preset unlocking password. After comparison, the processing unit 130 will determine that the second digit of the user's eye opening and closing state code PUC' does not match the preset unlock password, so the processing unit 130 will immediately determine the user's eye opening and closing state The code PUC' does not match the preset unlock code, and maintains the locked state of the lock 110 .

It is also worth mentioning that in the password input method described in the embodiment of the present invention, the step S350 of judging whether the code of the eye opening and closing state conforms to the preset unlocking password is not limited to the embodiment of Figure 6A to Figure 6E . One is used as a specific judgment method, but at least two of the judgment methods in Fig. 6A to Fig. 6D can be used together, so as to set the number of blinks/blink frequency/eye opening duration/eye closing duration at the same time. At least the judging conditions of the two are used as the default unlocking password.

For example, the designer can set the default unlock password to perform 3 consecutive eye blinks (that is, the preset number of blinks is equal to 3), followed by 9 to 11 seconds of eye-closing movements (that is, the default The eye-closing time ranges from 9 to 11 seconds). At this time, if the processing unit 130 obtains the blink code in the format of “101010000000”, it can determine that the blink code matches the preset unlock password. In other words, under this default unlock password, the user needs to blink 3 times (corresponding to 3 blink codes "10") and then keep closing the eyes for 9-11 seconds (corresponding to 6 second codes "0") action, the processing unit 130 will determine that the user's eye opening and closing state code matches the preset unlocking password. Here, the above-mentioned conditions are only illustrative examples, and the present invention is not limited thereto. Furthermore, any combination of conditions formed by the number of blinks/blink frequency/continuous eye opening time/continuous eye closing time is included in the scope of the embodiments of the present invention.

In addition to the above steps of unlocking based on the opening and closing of the eyes, the embodiment of the present invention also proposes a password input method for judging whether the user has an emergency, and the specific steps are shown in FIG. 8 .

FIG. 8 is a flow chart of steps for judging whether an emergency situation occurs according to an embodiment of the present invention. Please refer to Fig. 8, in this embodiment, the password input method can be performed before the step S350 of judging whether the user's eye opening and closing state code conforms to the preset unlocking password (or at the same time, the present invention is not limited thereto) Firstly, it is judged whether the user's eye opening and closing state code matches the emergency code (step S810 ). Wherein, if it is judged that the user's eye opening and closing state code matches the emergency password, it means that the user may be in an emergency situation (such as being held hostage), so at this time the processing unit 130 will send an emergency message (step S820) to the Security unit, thereby notifying the security unit that there is an abnormal state; on the contrary, if it is judged that the user’s eye opening and closing state code does not conform to the emergency code, then further judge whether the eye opening and closing state code conforms to the preset unlocking code Step S350.

Here, the specific method of comparing the code of the user's eye opening and closing state with the emergency help code can refer to the relevant description on comparing the code of the eye opening and closing state with the preset unlocking password (implemented in Figures 6A to 7E). example), so it will not be repeated here.

The following uses the embodiment of FIG. 9 to illustrate the practical application example of the above-mentioned security device and password input method for unlocking based on the opening and closing state of the eyes. Wherein, FIG. 9 is a schematic diagram of an access control system for unlocking based on the state of opening and closing of eyes according to an embodiment of the present invention.

Referring to FIG. 9 , the access control system 900 includes a lock 910 , an imaging unit 920 , a processing unit 930 , a prompt unit 940 and a door body 950 . The lock 910 is disposed on the door body 950 and is used to control the opening or closing of the door body 950 . In this embodiment, the prompt unit 940 is, for example, a light signal display device (but not limited thereto) that prompts that the current configuration state of the lock 910 is a locked state or an unlocked state with a light signal.

In this embodiment, the imaging unit 920 is arranged on the door body 950, for example, and is covered by a cover body 960 so that only an image capturing area is exposed in the imaging direction of the imaging unit 920, so that the user can The eye area can be aligned with the image capture area, so that the image capture unit 920 can capture image sequences for the user's eye area, and avoid peeping by others, thereby improving the security of the access control system 900 . Here, the setting of the cover body 960 is also the designer can choose whether to add it according to his design requirements, and the present invention is not limited thereto.

Based on the architecture of the access control system 900, the processing unit 930 can detect the eye movements/actions made by the user according to the sequence of images captured by the imaging unit 920 through the steps of the above-mentioned embodiments in FIG. 2 to FIG. 6E. eye opening and closing state, and judge whether the user’s eye opening and closing state code conforms to the preset unlocking password, and then decide whether to send a corresponding control signal to control the unlocking state of the lock 910 according to the judgment result, so that the user can Open the door body 950 to enter the area behind the door body 950 .

To sum up, the embodiment of the present invention proposes a password input method based on eye opening and closing state and a security device using it. The password input method may use specific eye movements (such as blinking, keeping eyes open and/or keeping eyes closed) as an unlocking password for unlocking the locked state of the lock. Since the user's eye movements are difficult to be peeped or noticed by others, the security of the access control system or other types of security devices using the password input method can be greatly improved, and the problem of password leakage can be prevented.
