With the development of the information age, smart wearable devices have attracted general attention in recent years as emerging products and are gradually applied to aspects of life. The smart wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The smart wearable device generally includes a motion sensor (gyroscope, height sensor, speed sensor, etc.), a position sensor, a heart rate sensor, etc., and can acquire motion information and health information of the user in real time. While the exercise information and health information may actually be used to determine the identity of the user, it is this relationship that is discovered and utilized by the solution of the present invention, as will be explained in detail in the following embodiments.
Example 1
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for unlocking by using a wearable device according to an embodiment of the present invention. As shown in fig. 1, a first aspect of the present invention provides a method for unlocking with a wearable device, which is applied to a smart door lock, and the method includes:
s1, receiving a handshake signal of a wearable device, and establishing connection with the wearable device based on the handshake signal;
s2, receiving real-time motion information sent by the wearable device;
s3, judging whether a user corresponding to the current wearable device meets an unlocking condition or not based on the real-time motion information, and if so, unlocking; otherwise, the lock is not unlocked.
In the embodiment of the invention, in the unlocking modes of radio frequency card swiping unlocking, APP unlocking, human face unlocking, fingerprint unlocking, iris unlocking and the like in the prior art, the radio frequency card, the human face, the fingerprint, the iris and the like are likely to be stolen and copied, and the APP has high risks of password leakage, Trojan/virus clamping and the like, so that the unlocking modes can not provide enough unlocking safety. The applicant has found that human gait also varies from person to person, in particular that certain gait details are very specific and, most importantly, that the gait information is hardly perfectly mimicked. Therefore, the invention utilizes the gait information of the person which is difficult to imitate to verify the identity, and realizes the unlocking of the entrance guard, thereby improving the unlocking safety of the entrance guard system.
During specific implementation, in a conventional state, the intelligent door lock is in a low-power-consumption monitoring state, when the wearable device enters a preset signal range, the intelligent door lock can receive a handshake signal of the wearable device, at the moment, communication connection can be established with the intelligent door lock, then real-time motion information sent by the wearable device can be quickly obtained, gait characteristics of a user can be analyzed based on the real-time motion information, and then whether the user has unlocking permission or not can be determined by comparing the similarity with the gait characteristics prestored in the intelligent door lock.
Wherein, wearable equipment's signal of shaking hands can adopt following mode is received to intelligence lock: 1) the intelligent door lock is in a low-power-consumption monitoring state, the wearable device sends a handshake signal for a certain time length to the outside after entering a building (the wearable device can stop sending after receiving a response signal of the intelligent door lock or does not have to be responded and stop sending after reaching the transmission time length), so that the wearable device can be received by the intelligent door lock when reaching the signal monitoring range of the intelligent door lock, and the intelligent door lock is awakened to perform identity verification and unlocking operation; 2) although the intelligent door lock is in a low-power-consumption monitoring state, the intelligent door lock further comprises other detection sensors (such as an infrared sensor, a sound pickup and the like) and a wireless activation device (such as an RF activator), wherein the other detection sensors enter a working state when the intelligent door lock is in the low-power-consumption monitoring state, the wireless activation device is activated when an object is detected to approach the intelligent door lock, the wireless activation device can further activate a handshake signal sending device on the wearable device, and then the intelligent door lock can receive a handshake signal at the moment, and then the intelligent door lock is awakened to perform identity verification and unlocking operations.
Optionally, the determining, based on the real-time motion information, whether a user corresponding to the current wearable device meets an unlocking condition includes:
and carrying out gait analysis on the real-time motion information to extract gait features, comparing the gait features with verification gait features prestored in the intelligent door lock, judging that an unlocking condition is met if the gait features are matched with the verification gait features, and otherwise, judging that the unlocking condition is not met.
Optionally, the wearable devices are at least two.
Optionally, the determining, based on the real-time motion information, whether a user corresponding to the current wearable device meets an unlocking condition includes:
receiving the real-time motion information of the at least two wearable devices to extract gait sub-features respectively, comparing the gait sub-features with verification gait features prestored in the intelligent door lock, judging that an unlocking condition is met if the gait sub-features are matched with the verification gait features, and otherwise, judging that the unlocking condition is not met.
Optionally, the gait feature and/or the gait sub-feature is a gait feature curve.
Referring to fig. 2, when a user approaches a smart door lock with a wearable device (e.g., the smart phone shown in fig. 2), the wearable device records motion information of the user in real time, including time, height, speed, position, and the like, and sends the motion information to the smart door lock, so that the smart door lock can draw a gait feature curve of the user based on the real-time motion information (the gait feature curve is replaced by the motion feature of the wearable device), wherein the wearable device can also be configured to draw a real-time gait feature curve, and then send the gait feature curve to the smart door lock. Therefore, the intelligent door lock can compare the obtained real-time gait characteristic curve with a prestored verification gait characteristic curve, for example, similarity calculation can be performed, if the similarity is greater than a preset value, it is determined that the current user has the unlocking authority, otherwise, it is determined that the current user does not have the unlocking authority.
In addition, as shown in fig. 3, the present invention also provides an improved scheme for acquiring gait characteristics. More and more people have begun to use more than one type of intelligent wearable device at present, such as intelligent bracelet, intelligent foot ring, intelligent leg ring etc. and these intelligent devices are worn respectively in different body parts. Thus, to further improve the accuracy of the gait feature analysis, the improved scheme of the invention fully utilizes the real-time motion information of a plurality of wearable devices worn on the body of the user to draw the gait sub-feature curve (the gait sub-feature curve in fig. 3 is only illustrative and does not reflect the absolute true curve). Before drawing, a plurality of wearing equipment need first carry out the networking communication, for example, intelligent bracelet and intelligent foot ring, intelligent leg ring communicate respectively in order to obtain its motion information/gait sub-characteristic curve, and the intelligent bracelet still is as the communication connection host computer with the intelligent lock to realize sending the motion information/the gait sub-characteristic curve of three wearable equipment for the intelligent lock by the intelligent bracelet. Correspondingly, the verification gait characteristics also comprise a plurality of verification gait sub-characteristic curves corresponding to the gait sub-characteristic curves, so that the intelligent door lock respectively performs similarity calculation on the received gait characteristic curves and the verification gait sub-characteristic curves, then performs weighted summation on the similarity calculation results, if the similarity calculation results are higher than a threshold value, it is determined that the current user has the unlocking authority, and otherwise, it is determined that the unlocking authority is not provided.
The above scheme is to match the gait characteristics in detail one by one, and in addition, a mode of matching the gait characteristics integrally can be adopted. The intelligent door lock endows different weights to the multiple gait sub-characteristics, then fits the received multiple gait sub-characteristic curves based on the weights (for example, a minimum binary method can be adopted) to obtain fitted gait curves for representing the overall gait characteristics, and then compares the fitted gait curves with the verified gait characteristics. The use of the weight can realize the highlighting of gait details with obvious characteristics, and the determination of the weight assignment can adopt the following modes: the wearable device finds the user limp based on the historical motion information of the user, the gait characteristic sub-curve corresponding to the wearable device of the foot of the user is obvious in characteristic, and at the moment, the intelligent door lock assigns a higher weight to the gait characteristic sub-curve.
Optionally, the weight assignment may also be adjusted in real time, and the wearable device may detect a motion characteristic that the user suddenly changes, and notify the smart door lock, so that the smart door lock sets an effective weight value for the corresponding gait characteristic sub-curve in the temporary period. For example, the wearable device finds that the user has a limp foot feature (for example, the user sprains the foot when playing a ball in the daytime) based on the movement information of the day, and then the real-time information is sent to the smart door lock through the network, so that the smart door lock can temporarily increase the weight of the gait feature sub-curve corresponding to the wearable device for the foot (the temporary validity period is, for example, 2 weeks), and when the user goes home at night, curve fitting can be performed based on the new weight, and then the unlocking verification judgment is performed. Therefore, the scheme of the invention can deal with some emergency situations, not only can realize unlocking safety, but also can ensure the unlocking effectiveness. Of course, all the weight determination methods in the overall matching scheme can also be used in the detail matching scheme described above.
Optionally, the real-time motion information further includes a motion direction and a position, and the intelligent door lock stores a map of a floor where the intelligent door lock is located;
then, the determining, based on the real-time motion information, whether a user corresponding to the current wearable device meets an unlocking condition further includes:
and the intelligent door lock judges whether a user corresponding to the wearable device has a confusion behavior or not based on the movement direction, the position and the map, if so, the user is judged not to meet an unlocking condition, and if not, the follow-up steps are executed.
In the embodiment of the invention, for some persons (especially acquaintances) with extremely strong imitation ability, the gait characteristics of other users can be imitated very similarly through talent training, so that the scheme of identity verification based on gait can be broken through. Aiming at the situation, whether a user corresponding to the wearable device generates confusion behaviors or not is further judged, and the confusion behaviors comprise that the user stops walking at a floor fork and looks at in different directions. If the person returns to his home, it is usually not judged which one is the resident of the person, but for a person who attempts to illegally sneak into another person, because of unfamiliarity, there is a misleading behavior that the person stays at the intersection of the floor and looks in different directions to determine the target resident. The intelligent door lock can judge whether the abnormal behavior exists or not based on the motion direction, the position and the floor map, and if the abnormal behavior does not exist, subsequent gait characteristic curve judgment is carried out.
