FIG. 1 is an exploded view of an identity confirmation device according to some embodiments of the present application; FIG. 2 is a cross-sectional view of an identity verification device according to some embodiments of the present application. It should be noted that the identity verification device shown in fig. 1 and 2 only has a living body recognition function, in which case the identity verification device may also be referred to as a living body recognition device, and is mainly used for the inner side of the door to realize the cat-eye prevention function. In addition to this, the identification device may have both an identification function and a living body recognition function. An identity verification apparatus having both an identity recognition function and a living body recognition function can be seen in fig. 7 and its description. In this case, the identification device is mainly used on the door outer side, and the fingerprint film attack prevention function is realized.

As shown in fig. 1 and 2, in some embodiments, identity confirmation device 100 may include a support bracket 120, a living body identification component 130, and a Printed Circuit Board (PCB) 140. In some embodiments, the living body identification assembly 130 may include a light emitting element 131 and a photo-receiver 132, a chip 134, and a flexible circuit board (FPC) 136.

The support frame 120 may include a support frame main body, which is a plate-shaped structural body, and the light emitting element 131 and the photoelectric receiver 132 are located below the support frame main body.

In some embodiments, the material of the supporting frame body may be a non-light-transmitting material. The supporting frame body may be formed with a first through hole 121 and a second through hole 122 corresponding to the light emitting element 131 and the photoelectric receiver 132. The light emitting element 131 can emit light to the measured object, the light emitted from the light emitting element 131 can be irradiated onto the measured object through the first through hole 121, the light reflected by the measured object is received by the photoelectric receiver 132 through the second through hole 122, the photoelectric receiver 132 can convert the received reflected light into an electrical signal, and the living body identification function can be realized according to the difference of the electrical signal.

Specifically, when light (hereinafter, infrared light is taken as an example, but not limited to) is irradiated on a finger of a human body, blood oxygen in the finger may absorb a part of the infrared light, and blood oxygen concentration in finger tissue may generate regular changes, which may directly cause regular changes in the amount of absorption of the infrared light by the blood oxygen. If the object is an inanimate object, the infrared light is not absorbed by the inanimate object, or the amount of absorption of the infrared light is constant, or the amount of absorption of the infrared light changes irregularly, so that the intensity of the infrared light reflected by the inanimate object forms a curve which is a constant straight line or an irregular curve, and the intensity of the infrared light reflected by the living object forms a regular curve. More specifically, different objects may cause different signal attenuations due to differences in the reflectivity of the material. For example, the lower end of the fingerprint film/sleeve may have a material with a reflectivity that is substantially different from the reflectivity of human tissue. This results in a large difference in the intensity of the infrared light after they have been reflected. Comparing the reflected infrared light intensity (average value) with a preset threshold value can distinguish whether the body to be detected has the material of the human tissue. For another example, the reflectivity of the material of the higher end fake finger, fingerprint film or fingerprint cover may be similar to the reflectivity of human tissue. But the blood oxygen concentration of a living body varies periodically due to the heart and the pulse. Due to the absorption of blood oxygen in human tissue to infrared light and the diffuse reflection characteristic of infrared light, the absorption amount of blood oxygen to infrared light also changes along with the change of blood oxygen concentration, so that the intensity of reflected infrared light can show periodic fluctuation. This fluctuation is not present even in the higher end of the fingerprint film/sleeve, which is similar in material to human tissue. Whether the subject is a living body can be discriminated by comparing the fluctuation value (difference between the maximum value and the minimum value) or the maximum slope or the like of the reflected infrared light with a preset threshold value. The above is only an example of the method for implementing living body identification, and the method for implementing living body identification by the identity verification device is not limited in the present application.

In some embodiments, the material of the supporting frame body may be a light-transmitting material. The transparent material may include glass, organic glass (PMMA), polyvinyl chloride, Polycarbonate (PC), Polystyrene (PS), or ABS plastic. The light emitted from the light emitting device 131 can pass through the main body of the support frame, and the light reflected by the measured object passes through the main body of the support frame and is received by the photoelectric receiver 132. Since the light shielding member 133 is provided, the light emitted from the light emitting member 131 cannot be directly received by the photo-receiver 132, and further description of the light shielding member 133 can be referred to below. In some embodiments, the number of the light emitting elements 131 and/or the first through holes 121 corresponding thereto is not limited to one in fig. 3, and may be 2, 3, 4, or more. In other embodiments, the number of the photoelectric receivers 132 and/or the second through holes 122 corresponding thereto may be plural.

In some embodiments, a shading element 133 may be further provided along the circumferential direction of the light emitting element 131 or/and the photoelectric receiver 132. The light shielding member 133 may isolate the light emitting element 131 from the photoreceiver 132 to prevent the light emitted from the light emitting element 131 from directly impinging on the photoreceiver 132, thereby ensuring the accuracy of the living body detection result. In some embodiments, the light blocking element 133 may also be located between the light emitting element 131 and the photoreceiver 132. In some embodiments, the shade element 133 can be a shade foam. Preferably, the light blocking element 133 may be a Polyurethane (PU) foam.

In some embodiments, the light emitting elements 131 may be light emitting diodes. The light emitting diode may include a visible light diode and a non-visible light diode. For example, the visible light emitting diode may include a red light emitting diode, an orange light emitting diode, a yellow light emitting diode, a green light emitting diode, a cyan light emitting diode, a blue light emitting diode, a violet light emitting diode, a white light emitting diode, or the like, or any combination thereof. The invisible light emitting diode may include an infrared light emitting diode, an ultraviolet light emitting diode, or an ultra-infrared light emitting diode. Preferably, the light emitting element in this embodiment is an infrared light emitting diode. More preferably, the infrared light emitting diode may emit infrared light having a wavelength of 830nm to 950 nm. More preferably, the infrared light emitting diode emits infrared light having a wavelength of 850nm or 940 nm.

The light emitting element 131 and the photo receiver 132 may be located on a flexible circuit board 136, and the light emitting element 131 and the photo receiver 132 may be connected to an external power source or an input/output device through the flexible circuit board 136. A printed circuit board 140 is disposed below the flexible circuit board 136, and the printed circuit board 140 can support the flexible circuit board 136 and electronic components such as the light emitting element 131, the photoelectric receiver 132, and the capacitive sensor 135 disposed above the flexible circuit board 136.

The support bracket 120 may also include a plurality of securing mechanisms 160. In some embodiments, the securing mechanism may include a first securing arm 161 and a second securing arm 162, wherein the first securing arm 161 is vertically disposed with respect to the support frame body and the second securing arm 162 is horizontally disposed with respect to the support frame body. The ends of the two ends of the first fixing arm 161 are respectively connected with the bottom of the main body of the support frame and the end of one end of the second fixing arm 162, and the second fixing arm 162 is located right below the main body of the support frame. The first fixing arm 161, the second fixing arm 162, and the support bracket 120 of the plurality of fixing mechanisms 160 form a limited space and fix the printed circuit board 140 and the living body recognition assembly 130. In other embodiments, other fastening means may be used to secure printed circuit board 140 and living identification assembly 130. For example, the fixing manner can also be threaded connection, clamping connection, welding connection and the like.

In some embodiments, the identity confirmation device 100 may also include a capacitive sensor 135. Capacitive sensor 135 is one specific embodiment of a wake-up device. The capacitive sensor 135 may be used to activate the identity confirmation device 100 from a sleep mode or a standby mode. The capacitive sensor 135 may be located between the support frame body and the flexible circuit board 136. The capacitive sensor 135 may be one or more. When there is one capacitive sensor 135, the capacitive sensor 135 may be located in a specific area of the main body of the support frame, and the detected object needs to touch or press the specific area, or slide on the specific area to activate the identity confirmation device 100. For example, when the capacitive sensor 135 is located in the middle region of the support frame body, the user needs to touch or press the middle region of the support frame body to activate the detection device for subsequent living body identification.

When the capacitive sensor 135 is plural, the plural capacitive sensors may be distributed in a certain shape (e.g., a circle, a square, a triangle, etc.) at the bottom of the support frame body. The shape of the plurality of capacitive sensors may be the same as the shape of the support frame body, each capacitive sensor corresponds to a small area of the support frame body, and the identity confirmation device 100 may be activated only when the detected object needs to trigger the plurality of capacitive sensors at the same time. The support frame body in this embodiment is circular, for example, a plurality of capacitive sensors may be arranged in a circle below the support frame body. For another example, when there are two capacitive sensors, the two capacitive sensors may be located on two sides of the center line of the support frame body and are symmetrical with respect to the center line of the support frame body.

In some embodiments, the activation region of the identity confirmation device 100 may be changed by adjusting the switch state of each capacitive sensor 135. For example, in some embodiments, the identity verification apparatus 100 may include a first capacitive sensor, a second capacitive sensor, a third capacitive sensor, and a fourth capacitive sensor, and each capacitive sensor is located at the bottom of the support frame body and is respectively disposed at an interval of 90 ° around the center of the support frame body, that is, if the first capacitive sensor is located at 0 ° and the second capacitive sensor is located at 90 °, the third capacitive sensor is located at 180 ° and the fourth capacitive sensor is located at 270 °. The user can input control information about the on/off state of each capacitive sensor in the identity verification device 100 through his personal device, and the chip 134 receives the control information and processes it to control the capacitive sensors or issue control commands (e.g., switching commands). For example, the control information is: the first capacitive sensor is in an on state, and the other capacitive sensors are in an off state, and at this time, if the detected body needs to perform living body detection, the area above the support frame main body corresponding to the first capacitive sensor needs to be triggered to activate the identity confirmation device 100. For another example, the control information may be: the first capacitive sensor and the third capacitive sensor are in an on state, the second capacitive sensor and the fourth capacitive sensor are in an off state, and the detected body needs to trigger the upper area of the support frame main body corresponding to the first capacitive sensor and the third capacitive sensor to activate the identity confirmation equipment. In this embodiment, the activation region of the identity verification device 100 can be changed by controlling the switch state of the capacitive sensor, thereby improving the safety level of living body identification.

In some embodiments, the identity verification device 100 may further include a key dome 150. The key dome 150 is another embodiment of the wake-up device, and the key dome 150 may be an arc dome with a convex center. In some embodiments, the key dome 150 may be a snap dome. The center point of the key dome 150 is located below the conductive part at the bottom of the printed circuit board 140, the conductive part at the bottom of the printed circuit board 140 may be two conductive contacts separately arranged from each other, when not pressed, the center point of the key dome 150 is not in contact with the conductive part at the bottom of the printed circuit board 140, the circuit of the identity confirmation device 100 is not communicated, when pressed, the key dome 150 deforms, the center point of the key dome 150 is in convex contact with the conductive part on the printed circuit board 140, thereby the circuit is switched on to form a loop, so that the identity confirmation device 100 is powered on and can start to work normally. In some embodiments, the key dome 150 may include a circular metal dome, a cross-shaped metal dome, a triangular metal dome, an oval metal dome, and the like. In a specific embodiment, a detected object applies a certain pressure (e.g., 50g to 80g) to the entire identity verification apparatus 100, and after the identity verification apparatus 100 moves by a certain mechanical stroke under the action of the pressure, the central point of the key dome 150 protrudes and contacts with the conductive portion on the printed circuit board 140, so that the identity verification apparatus 100 can normally operate. The operation of pressing the identity confirmation device 100 is added in the embodiment, so that the operation complexity in the living body identification process can be increased, the operation complexity of illegal personnel is increased, and a better security effect can be achieved.

In some embodiments, the identity confirmation device 100 may further comprise an optical lens 110. The optical lens 110 may be located above the main body of the stand and fixedly connected to the main body of the stand. The optical lens 110 may encapsulate elements (e.g., the capacitive sensor 135, the light-emitting element 131, and the photoreceiver 132) in the identity confirmation apparatus 100, so as to prevent external dust and other substances from entering the identity confirmation apparatus 100. The optical lens 110 can also transmit the infrared light of the light emitting element 131, and can make the infrared light irradiate on the object placed on the surface thereof. The optical lens 110 can also transmit the infrared light reflected by the measured object and be received by the photoelectric receiver 132. In some embodiments, the optical lens 110 may also filter out or attenuate light of certain wavelengths. In some embodiments, the optical lens 110 needs to have a light transmittance (also called transmittance, total light transmittance) of at least 45% or more. Light transmittance may refer to the percentage of the luminous flux transmitted through an optical lens to the luminous flux incident thereon. In some embodiments, the material of the optical lens 110 may include glass, polymethyl methacrylate (PMMA), polyvinyl chloride (pvc), Polycarbonate (PC), Polystyrene (PS), or ABS plastic. The optical lens 110 is adapted to the light emitting element. For example, when the light emitting device is an infrared light emitting device, the optical lens 110 can be penetrated by infrared light. For another example, when the light emitting element is a white light emitting element, the optical lens used can be penetrated by white light.

In some embodiments, the upper surface of the carrier body may be provided with a flange structure 123 adapted to the optical lens 110, and the optical lens 110 may be fixed in the flange structure 123. In other alternative embodiments, the fixing manner of the optical lens 110 may further include adhesion, screw connection, clamping, etc., which is not limited herein. In addition, reference may be made to the description elsewhere in this specification regarding the details of the optical lens 110.

It is to be noted that the above description of the identity confirmation device is merely a specific example and should not be considered as the only possible embodiment. It will be obvious to those having skill in the art that, having the benefit of the teachings of the present principles of identity verification apparatus, various modifications and changes in form and detail may be made to the specific manner in which the identity verification apparatus is implemented without departing from such principles, but such modifications and changes are intended to be within the scope of the foregoing description. For example, the living body identification apparatus is not limited to the installation manner in the drawing, and may be installed by being rotated by 90 ° or other angles. For another example, the optical lens 110 may be located on the outer side of the supporting frame 120, and attached to the supporting frame 120 by some kind of bonding or connecting method. Such variations are within the scope of the present application.

FIG. 3 is an exploded view of a door handle with an identity confirmation device according to some embodiments of the present application; FIG. 4A is a top view of a door handle with an identity confirmation device according to some embodiments of the present application; FIG. 4B is a cross-sectional view of a door handle with an identity confirmation device according to some embodiments of the present application. Referring to fig. 3, 4A and 4B, the door handle 300 may include a handle 320, a handle cover 310 and the identity confirmation device 100. The handle 320 and the handle cover 310 may enclose and secure the identity verification device 100. In some embodiments, the handle 320 and the handle cover 310 may be removably connected by screws 330. In other embodiments, the handle 320 and the handle cover 310 may be removably connected by other means (e.g., snap fit).

In some embodiments, the interior of the handle 320 is provided with a recess for placement of the identity confirmation device 100. The grooves may include a first groove 340 and a second groove 350, the first groove 340 communicates with the second groove 350, and the second groove 350 has a depth smaller than that of the first groove 340. The second fixing arm 162 of the fixing mechanism 160 is located in the first groove 340, the printed circuit board 140 is located right above the second groove 350, and the key dome 150 is located in the second groove 350. When no external pressure acts on the identity confirmation device 100, the bottom of the second fixing arm 162 has a certain distance with the bottom of the first groove 340, when external pressure acts on the identity confirmation device 100, the whole identity confirmation device 100 can be displaced downwards, and when the edge point of the key dome 150 is connected with the conductive part of the printed circuit board 140, the bottom of the second fixing arm 162 can be contacted with the bottom of the first groove 340. At this time, the identity verification device 100 can be awakened, and the key dome 150 is prevented from being excessively deformed due to an excessive external pressure, so that the service life of the key dome 150 is prolonged.

It should be noted that the number of the first grooves 340 may be the same as the number of the second fixing arms 162 in the fixing mechanism 160, and each of the second fixing arms 162 is located directly above each of the first grooves 340.

In some embodiments, an opening is defined in the handle cover 310 and is located directly above the optical lens 110. The size of the flange structure 123 on the upper surface of the support frame main body is smaller than that of the support frame main body, so that a first limiting structure is formed between the outer side of the flange structure 123 and the support frame main body, and a second limiting structure (namely, a groove) matched with the first limiting structure is formed in the inner wall of the handle cover 310, so that the identity confirmation device 100 cannot deviate in the handle 320. In some embodiments, the top of the flange structure 123 may be flush with the top of the handle cover 310, may extend above the top of the handle cover 310, or may be lower than the top of the handle cover 310. In other embodiments, the location of the identity confirmation device 300 is not limited to the locations shown in fig. 3, 4A, and 4B, and may be located in a middle region of the handle 320 or on the other side of the handle, for example. In some embodiments, the location of the identity confirmation device 100 is not limited to the handle shown in fig. 3, 4A and 4B, and may be located in other positions inside and outside the door, which is not limited in this application. In some embodiments, the identity confirmation device 100 or a door handle containing the identity confirmation device 100 may also have an anti-peep function when used inside a door. Specifically, a thief may extend a mechanical arm or mechanical link into a cat eye and unlock the door by pressing a door handle. However, when the identity verification device is applied to the door lock, the identity verification device not only has the awakening requirement, but also needs to be identified through living bodies, so that the door lock can be effectively prevented from being opened by illegal personnel from the inner side of the door through the cat eye hole.

In some embodiments, the identity confirmation device 100 may be in a plurality of states, such as a standby state, a sleep state, an active state, and the like. When in the sleep state, most of the components in the identity confirmation device 100 may be in a power saving mode (low power mode) or an off state. One or more elements of the wake-up unit may remain active at this time. For example, the capacitive sensor 135 and its associated circuitry may be in an active state, continuously scanning its surface for capacitive sensing information, and waking up the object when it touches, slides, or approaches its surface. For another example, the key dome 150 and its related circuits may also be in a working state, and continuously monitor whether there is a key signal (i.e. whether the related circuits of the key dome 150 are turned on), and after the detected object is pressed for a certain distance, the related circuits may be turned on to wake up the detected object. The wake-up unit may send a signal to the chip 134 after the wake-up unit detects the detected object and wakes up the other components of the identity verification device 100 (e.g., the living body identification module 130) from the sleep state by sending a control signal to the chip 134. The living body identification component 130 may begin living body identification of the subject. In some embodiments, the wake-up device may be awakened by touching it with a non-living foreign object, such as metal (e.g., a mechanical linkage that extends through the cat-eye opening). In this case, even if the wake-up apparatus is awakened, the identity confirmation device rejects the subsequent unlocking operation since it cannot be recognized by the living body recognition of the living body recognition component 130. When the living body identification component 130 identifies that the subject is a living body, a signal may be sent to the chip 134. The chip 134 may send a command to a driving device (e.g., a motor) of the smart door lock, etc., to unlock or unlatch the smart door lock. In some embodiments, if the identification is passed, the components of the identity verification device 100 may enter the standby state after recognizing a certain time (e.g., 1s, 2s, 3s, 4s, etc.) after the door lock is closed. At this time, if the wake-up device detects a new subject, the living body identification module 130 can be quickly awakened and put into an operating state. If the identification fails, the components of the identity verification device 100 may enter a standby state directly after a certain time (e.g., 1s, 2s, 3s, 4s, etc.). If the standby state is entered, after a certain time (e.g., 1s, 2s, 3s, 4s, etc.), most of the components of the identity confirmation apparatus 100 except the wake-up device may be transferred from the standby state to the sleep state to reduce power consumption.

Fig. 5 is an exploded view of yet another identity confirmation device according to some embodiments of the present application. As shown in fig. 5, the present specification also provides an identity confirmation device 500. The identity confirmation device 500 in this embodiment may include a support frame 530, a light emitting element 590, a photo receiver 580, a capacitive sensor 570, and a printed circuit board 550. Wherein the key dome 560 may be located at the bottom of the printed circuit board 550. It should be noted that the identity confirmation device 500 is a modified embodiment of the identity confirmation device 100 and may be used instead of or in addition to the identity confirmation device 100. The design of the door handle 400 in fig. 4 is mainly based on the structure of the identification device 100, but it may be modified according to the structure of the identification device 500.

In this embodiment, the light emitting element 590 and the photo receiver 580 may be located on the printed circuit board 550, the supporting frame 530 may be located above the printed circuit board 550, and the supporting frame 530 is located directly above the light emitting element 590, the photo receiver 580, and the capacitive sensor 570. The number of the light emitting elements 590 in this embodiment may be two, and the two light emitting elements 590 are respectively located at two sides of the photo-receiver 580. A light shielding element 540 may be further disposed between the supporting frame 530 and the photoelectric receiver 580, and the light shielding element 540 does not block the light path above the light emitting element 590 but blocks the direct light irradiation between the light emitting element 590 and the photoelectric receiver 580. This allows the light emitted from the light emitting element 590 to penetrate the supporting frame 530 and irradiate the subject. The position of the light shielding element 540 opposite to the photo-receiver 580 may be opened with a receiving hole 541, so that the light of the light emitting element 590 reflected on the object to be tested can be received by the photo-receiver 580 through the receiving hole 541. In this embodiment, the supporting frame 530 may be made of a transparent material. In other alternative embodiments, the supporting frame may be made of a non-light-transmitting material, and through holes may be formed at positions of the supporting frame 530 opposite to the light-emitting element 590 and the photoelectric receiver 580, so that light can penetrate through the supporting frame 530.

In some embodiments, the capacitive sensor 570 may be semi-circular in shape. Two semicircular ring-shaped capacitive sensors 570 are symmetrically disposed about the center of the light emitting element 590 and the photoelectric receiver 580. In other embodiments, the number of the capacitive sensors 570 may be one or more than two.

In some embodiments, the identity confirmation device 500 may further comprise a spacing structure 520. The position limiting structure 520 may be used for fixing and limiting the position of the supporting frame 530. The limiting structure 520 is matched with the shape of the supporting frame 530.

Fig. 6 is an exploded view of a housing structure according to some embodiments of the present application. As shown in fig. 6, in some embodiments, the identity confirmation device 500 may be mounted in a housing structure 600 (if not specifically stated, the housing structure 600 containing the identity confirmation device 500 may also be referred to as an identity confirmation device). The housing structure 600 may be used to enclose the components (e.g., the printed circuit board 550, the light emitting element 590, the photo receiver 580, the capacitive sensor 570, the retaining structure 520, the optical lens 510, etc.) in the identity verification device 500 described above. It should be noted that the housing structure 600 in this embodiment may also be applied to the identity verification device 100 in fig. 1 and the embodiment thereof, and when the housing structure 600 is applied to other embodiments, the housing structure may be adapted according to the specific structure of the identity verification device.

The housing structure 600 may include a first housing structure 620 and a second housing structure 610.

In some embodiments, a buffer 630 may be further disposed between the printed circuit board 550 and the placement groove 622, the buffer 630 may be adapted to the printed circuit board 550 and the placement groove 622, and the buffer 630 may effectively reduce the collision and wear between the printed circuit board 550 and the placement groove 622 inside the identity verification apparatus 500 during the operation process. In some embodiments, the material of the buffer 630 may include silicone, rubber, plastic, or the like, or any combination thereof. In some embodiments, the first protrusion 623 engaged with the center point of the key dome 560 may be further disposed in the positioning groove 622. When the tested object presses the components (e.g., the optical lens 510, the supporting frame 530) of the identity confirmation apparatus 500, the key dome 560 at the bottom of the printed circuit board 550 may deform under the action of the first protrusion structure 623, and the center point of the key dome 560 protrudes, so as to complete the circuit to activate the identity confirmation apparatus 500. After the detected object is detected, the button dome 560 recovers deformation when losing the acting force, and the circuit is disconnected, so that the identity verification device 500 enters a standby mode. Correspondingly, the upper surface of the buffer 630 may be provided with a second protrusion structure 631 matching with the first protrusion structure 623, the second protrusion structure 631 is hollow, and the first protrusion structure 623 may extend into the second protrusion structure 631 from the bottom of the buffer and be connected to the second protrusion structure 631 in a sleeved manner.

It should be noted that the identity verification device 500 can be applied to the inner side of the door, so as to prevent an illegal person from unlocking the door through the peep hole, thereby improving the security effect of the door lock. In other embodiments, the identity verification device 500 may also be applied to the outside of the door, with the addition or combination of other identity recognition units (e.g., fingerprint or/and palm print recognition unit, finger vein recognition unit, face recognition unit, iris recognition unit, etc.) forming a detection device with both biometric and identity recognition functions. In some embodiments, the identity confirmation device 500 in the above embodiments may be used for security devices (e.g., door locks, gates), attendance devices (e.g., attendance machines), transportation devices (e.g., transportation cars, containers), and the like. A specific embodiment of the detection apparatus having both the living body recognition function and the identity recognition function can refer to fig. 7 and its description.

It is to be noted that the above description of the identity confirmation device is merely a specific example and should not be considered as the only possible embodiment. It will be obvious to those having skill in the art that, having the benefit of the teachings of the present principles of identity verification apparatus, it is possible to effect numerous modifications and variations in the form and details of the specific procedures and procedures for carrying out the identity verification apparatus without departing from such principles, but that such modifications and variations are within the scope of the above description. For example, the supporter 320 is not limited to a circular shape, but may be an oval shape, a regular or irregular polygon, etc., as long as the optical lens 110 is adapted to the supporter main body. For another example, the housing structure 600 may not be limited to a cylindrical shape, but may be a polygonal prism structure (e.g., a triangular prism, a cube, etc.) or an irregular structure. Such variations are within the scope of the present application.

Fig. 7A is a cross-sectional view of an identity confirmation device according to some embodiments of the present application. Fig. 7B is a top view of an identity confirmation device according to some embodiments of the present application. As shown in fig. 7A and 7B, in some embodiments, the identity confirmation apparatus 700 may include an optical lens 710 (also referred to as a light-transmitting plate), a photoelectric receiver 720, a chip (not shown in the figures, and may be similar to the chip 134), a fingerprint scanner 740, and an infrared light emitting element 750.

The fingerprint scanner 740 may be used to scan a fingerprint image of a subject. The fingerprint image is an image obtained by collecting uneven lines on the front skin at the tail end of a finger by using image collecting equipment. The lines of each fingerprint image are regularly arranged to form different line types and the minutiae characteristics of the starting point, the end point, the combination point, the branch point and the like of the lines.

The infrared light emitting element 750 can emit infrared light of a certain wavelength. The photoelectric receiver 720 may be configured to receive infrared light emitted from the measured object and convert the infrared light intensity of the infrared light reflected by the measured object into an electrical signal. In the present embodiment, an infrared light emitting diode is preferable, but not limited to the infrared light emitting diode. In some embodiments, the infrared light emitting element 750 can also be other color light emitting elements, such as a red light emitting element, a blue light emitting element, a white light emitting element, and the like. Accordingly, the infrared light emitting element 750 is adapted to the photo receiver 720.

It is to be noted that the infrared light emitting element 750 and the photoelectric receiver 720 are not limited to one set shown in fig. 7A and 7B, and may be a plurality of sets (e.g., two sets, three sets, four sets, etc.). In some embodiments, the sets of infrared light emitting elements 750 and the photo receivers 720 can respectively emit and receive infrared light of different wavelengths. The emitting and receiving processes of the sets of infrared light emitting elements 750 and the photo-electric receivers 720 may be simultaneous or sequential.

In some embodiments, the infrared light emitting element 750 and the photoreceiver 720 may be oppositely disposed. For example, the infrared light emitting element 750 may be located on one side of the fingerprint scanner 740 and the photo receiver 720 may be located on the other side of the fingerprint scanner 740. In some embodiments, the infrared light emitting element 750 and the photoelectric receiver 720 may be respectively located at two corner sides of a diagonal line of the fingerprint scanner 740.

In some embodiments, the upper surface of the infrared light emitting element 750 and the upper surface of the photoreceiver 720 are not higher than the upper surface of the fingerprint scanner 740. It should be noted that the infrared light emitting element 750 is a device capable of emitting infrared light, in the embodiment provided in this specification, the infrared light emitting element 750 is used to emit infrared light to a subject, the photoelectric receiver 720 receives the infrared light reflected by the subject, the photoelectric receiver 720 converts the received infrared light into an electrical signal, and the chip determines the strength of the electrical signal to realize the living body detection function. If the infrared light is directly irradiated to the photoelectric receiver 720, the intensity of the infrared light reflected from the object is covered by being several orders of magnitude smaller than the intensity of the infrared light directly irradiated to the photoelectric receiver 720, and the living body identification of the object is very inaccurate. Therefore, the infrared light emitted from the infrared light emitting device 750 cannot directly irradiate the photoelectric receiver 720 (it needs to irradiate the object to be measured through the optical lens 710, and then irradiate the photoelectric receiver 720 after being reflected by the object to be measured and passing through the optical lens 710).

As shown in fig. 7A, the optical lens 710 may be disposed on the fingerprint scanner 740, the infrared light emitting device 750 and the photoelectric receiver 720, the infrared light emitted by the infrared light emitting device 750 is transmitted through the optical lens 710 to illuminate the object, the photoelectric receiver 720 receives the infrared light reflected by the object, and the fingerprint scanner 740 scans the fingerprint image of the object disposed on the optical lens 710.

The optical lens 710 may isolate the internal components of the identity confirmation device 700 from the outside, preventing foreign objects from entering the identity confirmation device 700. The optical lens 710 may also transmit infrared light from the infrared light emitting element 750, and may cause the infrared light to irradiate a subject placed on its surface. The optical lens 710 may also transmit infrared light reflected by the object to be measured, and be received by the photoelectric receiver 720.

Only taking the infrared light emitting device 750 as an example in this embodiment, the infrared light emitted by the infrared light emitting device 750 can be transmitted through the optical lens 710 to irradiate the object to be measured, due to the diffuse reflection characteristic of light, the object to be measured will reflect the infrared light, the reflected infrared light is received by the photoelectric receiver 720, the photoelectric receiver 720 will convert the received infrared light into an electrical signal, and the electrical signal will change with the intensity of the infrared light.

The chip is connected with the photoelectric receiver 720, the infrared light emitting element 750 and the fingerprint scanner 740. In some embodiments, the chip may determine the result of the living body identification of the subject from the infrared light received by the photoreceiver 720. In some embodiments, the chip may further retrieve the fingerprint image of the detected object from a pre-recorded fingerprint image set to determine a fingerprint identification result.

It should be noted that, since the blood oxygen in the finger tissue has an absorption effect on the infrared light, and when the infrared light irradiates the finger tissue, the blood oxygen concentration in the finger tissue changes, and the absorption amount of the infrared light by the blood oxygen also changes with the change of the blood oxygen concentration, the photoelectric receiver 720 converts the infrared light into an electrical signal, and transmits the electrical signal to the chip for analysis, and the chip determines whether the detected object is a living object according to whether the intensity of the electrical signal changes.

In some embodiments, one or more user fingerprint image entries may be stored in advance in a storage device or database, resulting in a set of fingerprint images. In the using process, the acquired fingerprint image of the detected object is matched and identified with the fingerprint images in the fingerprint image set, if the fingerprint characteristics of the fingerprint image of the detected object and the fingerprint characteristics of one fingerprint image in the fingerprint image set are the same, the fingerprint matching is successful, and the fingerprint identification is determined to be passed. If the fingerprint image of the detected object is not matched with the fingerprint characteristics of the fingerprint images in the fingerprint image set, the fingerprint matching is not successful, and the fingerprint identification is determined not to pass.

In some embodiments, only when the measured object is a living body, the measured object is subjected to fingerprint identification, and a fingerprint identification result is obtained. When the measured object is a non-living object, fingerprint recognition is not performed. In some embodiments, the live subject is identified only when the subject's fingerprint identification passes. And when the fingerprint identification of the detected body does not pass, the living body identification is not carried out. Alternatively, live recognition and fingerprint recognition (or other identification) may be performed simultaneously, and a detection result may be determined based on the results of the live recognition and the fingerprint recognition.

In some embodiments, the identity confirmation device 700 may also include a support plate 730. The supporting plate 730 is disposed under the fingerprint scanner 740, in contact with the fingerprint scanner 740, the infrared light emitting element 750, and the photo receiver 720, for supporting the fingerprint scanner 740, the infrared light emitting element 750, and the photo receiver 720. In some embodiments, the support plate 730 may be a printed circuit board, a flexible circuit board, etc., but is not limited thereto.

Based on the above identity confirmation device 700, the following illustrates the implementation principle:

when a human finger touches the optical lens 710, the wake-up device can wake up the infrared light emitting element 750. The infrared light emitting device 750 emits infrared light, the infrared light passes through the optical lens 710 and irradiates a finger, the finger reflects the infrared light and then passes through the optical lens 710 to be received by the photoelectric receiver 720, and the photoelectric receiver 720 converts the received infrared light into an electrical signal and transmits the electrical signal to a chip for processing. If the detected object is a finger of a living body, when infrared light normally irradiates the finger tissue, the blood oxygen concentration in the finger tissue changes, and the absorption amount of the infrared light by the blood oxygen also changes with the change of the blood oxygen concentration, at this time, the intensity of the infrared light received by the photoelectric receiver 720 changes periodically, the photoelectric receiver 720 converts the changed intensity of the infrared light into a changed electric signal, and the chip determines that the detected object is a living body through the changed electric signal. If the measured object is an inanimate object, when infrared light irradiates the measured object, the measured object reflects the infrared light, and since the measured object is an inanimate object, the intensity of the infrared light received by the photoelectric receiver 720 is constant, the intensity of the infrared light converted by the photoelectric receiver 720 into an electrical signal is also constant, and the chip can determine that the measured object is an inanimate object through the constant electrical signal. When a living body is detected, fingerprint identification (which is one type of identity identification) is performed on a fingerprint image scanned during living body fingerprint detection, the fingerprint identification is performed by searching a fingerprint image of the detected body from a preset fingerprint image set, when a fingerprint image with the same fingerprint characteristics as the fingerprint image of the detected body is searched, the fingerprint identification is determined to be passed, and if a fingerprint image with the same fingerprint characteristics as the fingerprint image of the detected body is not searched from the fingerprint image set, the fingerprint identification is determined not to be passed. The identity verification device 700 provided by this embodiment can determine the result of the living body identification by performing the living body identification on the detected object, and then identify the fingerprint of the detected object to determine the result of the fingerprint identification, and the security of the fingerprint lock adopting the fingerprint identification technology can be improved by adopting the double verification.

It should be noted that the above-described identity verification device 700 has functions of living body recognition and identity recognition. The identity confirmation device 700 may be disposed outside the door to confirm the identity of the user and then determine whether to unlock the door to allow the user to enter the room. In other embodiments, the identity confirmation device 700 may also have only a living body recognition function or an identity recognition function. For example, the identity verification device 700 may omit the fingerprint scanner 740, and the identity verification device 700 may only have a living body recognition function (e.g., the identity verification device 100 of FIG. 1 or the identity verification device 500 of FIG. 5). At this time, the identity confirmation apparatus can be applied to the door inner side setting of the peep hole preventing door lock. Therefore, when the door is unlocked from the inner side of the door, the living body detection is needed, and the door lock can be prevented from being opened from the inner side of the door by illegal personnel through the cat eye hole. For another example, the identity verification apparatus 700 may omit the infrared light emitting element 750 and the photoelectric receiver 720, and thus only have an identity recognition (e.g., fingerprint recognition) function.

The beneficial effects that may be brought by the embodiments of the present application include, but are not limited to: in some embodiments, the identity confirmation device has higher awakening requirements and stricter living body identification requirements, and can have a cat eye prevention function, namely, effectively prevent a thief from extending a mechanical connecting rod and the like into the cat eye from the outside of the door to open the door lock from the inside of the door, and improve the safety of the intelligent door lock. In other embodiments, the identity confirmation equipment can also have a living body identification function and an identity identification function at the same time, so that a non-authorized person is prevented from entering the door lock from the outside by a method of fake finger counterfeiting, and the safety of the intelligent door lock is also improved. It is to be noted that different embodiments may produce different advantages, and in different embodiments, any one or combination of the above advantages may be produced, or any other advantages may be obtained.
