The intelligent home is embodied in an internet-of-things manner under the influence of the internet. The intelligent home connects various devices (such as audio and video devices, lighting systems, curtain control, air conditioner control, security systems, digital cinema systems, audio and video servers, video cabinet systems, network home appliances, mobile terminals and the like) in the home through the Internet of things technology, and provides multiple functions and means such as home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environment monitoring, heating and ventilation control, infrared forwarding, programmable timing control and the like. The smart home not only needs to provide products, but also needs to integrate comprehensive services, adopts unified management and unified services, and improves the quality of the smart home services, so that the smart home one-stop services including community shopping, community restaurants, community clubs, community medical services, property services, government public information suits and other services, such as property services, telemedicine, online shopping, teleeducation, online ordering and ticket booking, can be provided through the operation platform. In the prior art, there are many smart home systems with different functions.
The smart home based on the Internet of things brings convenience to life of people and simultaneously solves the problem of leakage of a large amount of private information. The individual behavior information of a person is not privacy-conscious, but the individual privacy information is formed when name information, address information, face information and behavior information of the person are arbitrarily associated. In the use of smart homes, home video information of personal life and even live broadcast information of personal life are stolen and leaked by irrelevant people at the cloud, and news which is browsed by the masses through the network at will is frequently seen. Recorded information and video information relating to private activities in hotels, hotels and the like are leaked in a large amount because they are not strictly managed.
A large number of individuals reject the settings of smart homes for fear of personal privacy leakage, so that current smart homes cannot be popularized in everyday homes. Therefore, the leakage of personal privacy is a great obstacle to the development of smart homes and is also an important problem to be solved currently.
A TOF (Time of Flight) sensor can emit laser light, calculate the arrival Time of the light reflected by the object, and determine the distance to the object. The measurement area is divided into a grid pattern, and by obtaining the distance for each grid point, three-dimensional distance data such as the position, height, width, and depth of an object located in the area can be obtained. Therefore, TOF sensors, which are a new generation of sensors for improving the leakage of private information, are applied to the internet of things instead of general image sensors, thereby avoiding the direct leakage of private information.
For example, chinese patent CN106375733A discloses an intelligent monitoring device and system, including: the power supply module and the control module are connected with the power supply module; the power supply module is used for supplying power to the control module; the control module includes: the system comprises a TOF sensor unit, a processing unit and a communication unit; the TOF sensor unit is used for acquiring images of monitored users; the image comprises positions of monitored users represented by pixel points with different colors; the processing unit acquires the motion trail of the monitored user by acquiring the image of the monitored user within a preset time period; the communication unit is used for sending the motion trail to the server so that the server can determine whether alarm information needs to be sent according to the motion trail of the monitored user. The TOF technology is adopted to conduct behavior recognition on the monitored user, behaviors of the monitored user are obtained under the condition that entity details are not collected, namely, areas such as bedrooms and bathrooms are monitored under the condition that privacy of the user is guaranteed.
Chinese patent CN111047827A discloses an intelligent monitoring method and system for environmental assisted life, the method comprising: a TOF camera acquires first three-dimensional point cloud data of a scene; the TOF camera sends the first three-dimensional point cloud data to a server; the server extracts first point cloud depth data of the first three-dimensional point cloud data; the server performs denoising processing on the first point cloud depth data to generate second point cloud depth data; the server extracts the human body edge contour of the second point cloud depth data to generate third point cloud depth data; the server restores the third point cloud depth data into second three-dimensional point cloud data; the server calculates the three-dimensional center coordinates of the human body according to the second three-dimensional point cloud data; the server extracts a height value of a human body center vertical to the ground direction in the three-dimensional human body center coordinates; the server compares the height value of the human body center with a first threshold value: and if the height value of the human body center is smaller than or equal to the first threshold value, the server sends alarm information to the terminal.
Chinese patent CN109658675A discloses a life law determination system and a life law determination method. In the lifestyle measurement system, the distance measurement device measures three-dimensional information (which is a standing posture, a sitting posture, or a lying posture, a movement amount, and no information) of a measurement target using a TOF sensor. The management device collects the three-dimensional information measured by the distance measurement device every unit time, estimates the life pattern of the measurement object (the ratio and the amount of movement of each posture per unit period, the absence time, the bedtime, the waking time, and the returning time) from the time change of the three-dimensional information, and stores the estimated life pattern in the storage device. The management device provides the measurement requester with information on the life rule of the measurement target stored in the storage device. Thus, the life pattern of the measurement object can be measured while protecting the privacy of the measurement object.
The above prior art uses the TOF sensor in the smart home system for avoiding the leakage of personal privacy behaviors. However, in real life, the acquisition of personal behavior information only through TOF only eliminates facial image information and video image information, and personal privacy information such as personal address information, behavior information, time information, and life rules of the people are still easy to steal and be utilized by others, which finally causes personal or national property loss. Therefore, it is not enough to eliminate facial information or body information, and how to make information not to cause privacy information leakage even if stolen is a key problem to solve privacy leakage can promote a great deal of popularization and development of smart homes.
Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.
Disclosure of Invention
In the prior art, the smart home system based on the cloud platform is designed to be very intelligent, but users are dared to be installed and used at home due to worry about privacy leakage caused by improper data management. The leakage and theft of home videos in social news further increase the worry of users about the leakage of private information, making the smart home system difficult to widely popularize.
In order to overcome the defects in the prior art, the invention provides a smart home system based on a cloud platform, which at least comprises; the cloud management platform at least comprises a verification unit and an information storage unit, the verification unit is provided with a user-defined checking authority level, the information storage unit stores real information and a user-defined name, and the verification unit responds to an information query request of at least one checking terminal and feeds back necessary query information corresponding to the checking authority level or a query result without unnecessary privacy information based on the checking authority level of the checking terminal. The invention determines the body posture characteristics of the individual through the three-dimensional contour information acquired by the TOF sensor, thereby avoiding the defect that the life information of the individual is stolen and leaked and propagated. The three-dimensional contour information does not contain the information of the five sense organs of the individual, thereby avoiding the leakage of the face information and the face image of the user. The cloud management platform provided by the invention can ensure that people with the checking authority can obtain necessary real information and can avoid the transmission of unnecessary private information by associating the checking authority level with the user-defined true and false information.
Under the condition that network information transmission is popularized, whether checking information fed back by a cloud management platform to checking terminals of communities or properties contains unnecessary privacy information or not or a large amount of unnecessary privacy information is fed back, and a user cannot know the information and cannot naturally find and take corresponding measures at the first moment of privacy leakage. In order to solve the technical problem, the mobile terminal provided by the invention is provided with a display unit, and when the verification unit feeds back the query information or the query result corresponding to the viewing permission level to the viewing terminal, the verification unit sends the fed-back query information or the fed-back query result to the display unit of the mobile terminal. The mobile terminal is used for the user to inquire the life information and set the control information, and has the function of monitoring the feedback information of the cloud management platform at the rear end, so that the output degree of the cloud management platform to the private data is mastered, the correlation between the custom viewing permission level and the private information is adjusted according to the self requirement, and the protection of the private data is realized.
Preferably, the control device determines the on-off and starting sequence of at least one controlled device related to the personal living state based on the personal three-dimensional profile information uploaded by the TOF sensor, the position and the time information. Because family personnel and visit personnel of the intelligent residential system are limited, the three-dimensional outline of each person cannot be completely the same, and the identity and the position of each person can be determined by identifying the three-dimensional outline information, so that corresponding controlled equipment conforming to the living habits of the persons is started, and the intelligent residential system can perform intelligent service for the users.
Preferably, at least one TOF sensor in the invention comprises an image acquisition component, the image acquisition component acquires personal images meeting user-defined acquisition conditions according to a set period and uploads the personal images to a cloud management platform and/or a mobile terminal, and the verification unit feeds back the personal images and/or the information related to the personal images to the viewing terminal when the viewing verification level of the viewing terminal is not lower than the user-defined viewing verification level. Personal images relating to a user and his family members belong to private information. However, when none of the family members is at home, the image of a stranger intruding into the house belongs to the monitored object, and a police department needs to be sent to determine the suspect if necessary. Therefore, under the condition of meeting the setting of the user, the personal image of the designated person and the body posture characteristic information thereof need to be collected and reserved so as to realize the purpose of alarming under the required condition. For example, the user-defined collection conditions are: the personal images of the non-family members are periodically acquired by the image primary device according to a preset time interval, or the personal images of the non-family members and behavior video images thereof are continuously acquired and stored in a real color image mode.
Preferably, under the condition that the user associates the information category with the custom viewing permission level, the verification unit feeds back the corresponding query information or query result when the viewing permission level of the viewing terminal is not lower than the custom viewing permission level. The personal privacy information of the user can be protected, and the condition that the user obtains the privacy information of the user by any checking terminal can be avoided. In the era of internet of things and the future thereof, a plurality of clients can acquire information of users, and even if the subjectively acquired information is not abused, the subjectively acquired information can be easily acquired by irrelevant personnel under the condition of improper management so as to carry out non-gratification utilization. Therefore, the acquisition information of the viewing terminal must be limited to only be able to acquire the necessary viewing results. For example, whether a specified person has a fever or leaves a limited area during epidemic situation management belongs to necessary information, and meanwhile, the terminal is checked to be incapable of acquiring information such as the living privacy, the living law, the hobbies and the like of the specified person. Therefore, the information of the designated person should not be acquired at one time to be regulated, and only the necessary information is acquired by the viewing terminal, so that the privacy of the person is properly protected. According to the invention, the possibility that a large amount of private data is acquired is eliminated by setting the permission and feeding back the viewing result of the viewing request.
Preferably, the verification unit feeds back the private identity information with the corresponding information detail degree based on the viewing permission level of the viewing terminal under the condition that the user associates the information detail degree with the custom viewing permission level. In the case where the smart home system is widespread, the importance of data information for each family corresponds to the importance of the identification card. The registered data account of each residential cloud management platform is necessarily private, encrypted, and not freely accessible. Based on the internet of things, the registered data account of each family is necessarily authenticated by a plurality of viewing terminals with requirements so as to acquire corresponding information. At this time, the level of detail of information display needs to be limited so as not to reveal privacy. For example, the community viewing terminal only needs to know that a few people live in the residence, and does not feedback on the specific names of the people who live, thereby also avoiding the possibility of community people divulging user privacy.
Preferably, the viewing permission level of the verification unit includes at least one verification factor associated with verification strength, and in the case that the viewing terminal sends the at least one verification factor to the verification unit, the verification unit feeds back the privacy information associated with the at least one verification factor based on the individual verification information or the joint verification information of the at least one verification factor of the viewing terminal. The higher the verification strength of the verification factor is, the higher the cracking difficulty and the counterfeiting difficulty of the verification factor are, so that the difficulty of obtaining the privacy information is improved. According to the invention, through the correlation of the verification factors of the verification strength, irrelevant personnel can not obtain privacy information by forging the checking terminal. Especially, the privacy information of the machine family members of the important personnel can be ensured to be obtained by necessary legal departments through the association authentication of a plurality of verification factors. For example, the authentication factor specified by the national legal department is associated with the fingerprint of the user for authentication at the same time, and the authentication unit feeds back the query result or related information of the query request.
Preferably, at least one TOF sensor collects personal body temperature information according to a preset time interval when collecting personal three-dimensional contour information, and the cloud management platform sends early warning information to the mobile terminal or at least one associated terminal under the condition that the personal body temperature is abnormal. Body temperature information is very important for the characterization of personal health. Therefore, under the condition that the cloud management platform is networked with the medical system, a community doctor serving the family can quickly acquire the illness information of the ill personnel and provide related medical opinions, and the family member can conveniently seek medical advice and the health management of the community is facilitated. Meanwhile, the community doctors cannot obtain unnecessary privacy information, and the privacy of the patients is protected.
Preferably, the verification unit feeds back user-defined unreal information to the viewing terminal under the condition that the viewing permission level of the viewing terminal is lower than the user-defined viewing permission level. For an irrelevant viewing terminal with insufficient viewing permission level, if the irrelevant viewing terminal does not obtain the desired information, the identity information is continuously disguised to try to obtain the data, and the feedback of the unreal information is beneficial to avoiding the continuous attack on the viewing terminal, so that the storage information of the cloud management platform is protected.
Preferably, the mobile terminal or the viewing terminal establishes data connection with the verification unit in a one-way ferry mode, and the information storage unit and the verification unit perform information interaction in an information encryption mode. The arrangement is favorable for keeping data secret in the transmission process, and the data is prevented from being intercepted and stolen in the transmission process. Even if the encrypted data is intercepted, the private information can be protected because the encrypted data cannot be decrypted.
The invention also provides a terminal management system based on privacy management, which at least comprises: the mobile terminal is in data connection with the cloud management platform, the mobile terminal is provided with a display unit, the cloud management platform feeds back privacy-related identity information and/or medical information of a patient to the verification terminal based on a special instruction of the verification terminal and three-dimensional contour information of dangerous situations acquired by the TOF sensor, and when the verification unit in the cloud management platform feeds back query information or query results corresponding to the checking authority level to the checking terminal, the verification unit sends the fed-back query information or query results to the display unit of the mobile terminal.
Preferably, under the condition that the mobile terminal and the cloud management platform establish data connection, the verification unit in the cloud management platform synchronously displays the content fed back to the verification terminal at the mobile terminal, so that the user and the information viewer can simultaneously master the provided information content and the detailed degree of the provided information, and the viewer is prevented from acquiring redundant privacy information.
Preferably, the system further comprises at least one TOF sensor, the at least one TOF sensor comprises an image acquisition component, the image acquisition component acquires personal images meeting user-defined acquisition conditions according to a set period and uploads the personal images to the cloud management platform and/or the mobile terminal, and when the personal images of designated personnel and body posture characteristic information thereof need to be acquired and retained under the conditions meeting the user setting, the verification unit feeds back the personal images and/or the personal image related information to the viewing terminal when the viewing verification level of the viewing terminal is not lower than the user-defined viewing verification level.
Preferably, in the case that the TOF sensor acquires a three-dimensional contour, the formed image is a depth image with an integration of a plurality of points and is displayed in a single unreal color, and the three-dimensional contour information is edge contour information without depth information of facial five-sense organ parts.

Detailed Description
The following detailed description is made with reference to the accompanying drawings.
The invention provides a cloud platform-based smart home system, and also can be a home management system with privacy management.
Example 1
As shown in fig. 1, the smart home system based on the cloud platform of the present invention includes at least one mobile terminal 1, a control device 2, a cloud management platform 3, a plurality of home appliances 4, and at least one TOF sensor 5.
At least one mobile terminal 1 and the control device 2 are respectively in data connection with the cloud management platform 3 in a wireless connection or wired connection mode. And at least one TOF sensor 5 and the cloud management platform 3 are in data connection in a wireless connection or wired connection mode. The control device 2 establishes data connection with a plurality of household appliances 4 in a wireless connection or wired connection mode. The data connection between at least one mobile terminal 1 and the control device 2 can be established in a customized manner by means of a wireless connection or a wired connection. The control device 2 comprises one or more of an application specific integrated chip, a gateway, a single server and a server group. The cloud management platform 3 comprises one or more of at least one server, an application specific integrated chip and a server group. The mobile terminal 1 at least comprises an intelligent ring, an intelligent bracelet, a computer, a portable computer, an aid, intelligent glasses and other electronic equipment with a display screen.
Preferably, the control device 2 comprises a temporary storage unit 21. In the case where the control apparatus 2 is disconnected from the cloud management platform 3 in data transmission, the control apparatus 2 temporarily stores data of several home appliances 4 in the temporary storage unit 21, and in the case where data transmission is resumed between the control apparatus 2 and the cloud management platform 3, uploads the data stored in the temporary storage unit 21 to the cloud management platform 3 and performs data interaction with the cloud management platform 3.
The TOF sensor 5 of the invention, belonging to an infrared sensor, is used for acquiring profile data of a user in a monitored area. TOF is an abbreviation of Time of Flight (Time of Flight) technology, i.e., a sensor emits modulated near-infrared light, which is reflected after encountering an object, and the sensor converts the distance of a shot object by calculating the Time difference or phase difference between light emission and reflection to generate depth information. The measurement range of the TOF sensor 5 can reach several meters, the precision is less than 2cm, the updating frequency per second can reach 30-60 fDs, and real-time contour measurement can be realized.
Preferably, in the case of the present invention in which a three-dimensional contour is acquired only by the TOF sensor 5, the formed image is a depth image in which a number of points are integrated, and an image that can be recognized by the human eye cannot be directly displayed. Preferably, the three-dimensional contour image is displayed in a single non-true color, as shown in FIG. 2. The non-true color refers to a color different from the true color of the object. Under the condition that the skin color difference, the hair difference and the eyeball color difference exist, the three-dimensional contour point set acquired and formed by the TOF sensor 5 cannot directly form and leak intuitive face information of the acquired personnel image, so that the face information of the user can be prevented from being directly leaked. Preferably, the three-dimensional contour information in the present invention is edge contour information that does not include depth information of specific facial features, so that the transmission amount of data information of the sensor and the data storage amount of the cloud management platform 3 can be reduced while avoiding privacy leakage of the user.
Since the three-dimensional contour characteristics of each person have personalized differences, the behavior track of one person and the other person can be determined through the three-dimensional contour information.
Preferably, the TOF sensor 5 of the invention collects at least once contour information containing depth information of facial five sense organs and transmits the contour information to the cloud management platform. After acquiring the depth information of facial features of an individual, the TOF sensor 5 only acquires the three-dimensional contour information of the same individual and confirms the behavior, and does not repeatedly acquire the depth information of facial features of the same individual.
Preferably, the TOF sensor 5 of the invention collects three-dimensional profile information of the individual by means of infrared pulses, while also recording body temperature data of the individual. And sending alarm information to at least one connected mobile terminal under the condition that the personal body temperature data is abnormal. The three-dimensional contour monitoring system has the advantages that the three-dimensional contour information acquisition and the user health monitoring are combined, and the user can find out the body abnormality of the user and family members in advance.
Preferably, the cloud management platform 3 includes at least a verification unit 31 and an information storage unit 32. An information storage unit 32 stores at least a name of the user, a custom name, and at least one verification factor associated with the verification difficulty parameter. The user-defined name has a unique association relation with the real identity characteristics of the user and the family members thereof. The real identity features comprise unique information such as real names and three-dimensional contour features. The custom name is not unique and can be a limited number. The verification factors include several verification factors having different verification strengths. The verification factor is a verification factor with uniqueness.
Preferably, the custom name of the present invention can be a dummy name that has a unique legal association with the user's real name. I.e., the custom name is a custom name registered at a national legal department, such as a household registration department. Under the condition that the checking authority level is insufficient, the verification terminal can only check the user-defined name of the user, and therefore leakage of privacy information formed by the real name of the user and the address/IP address is avoided.
Preferably, the stored information of the information storage unit 32 further includes basic data related to privacy, such as the depth information of the individual's five sense organs, facial image information, the place where the action occurred, the time, and the like. Preferably, the basic data further includes information of age, sex, daily living address information, daily living room, etc. of the individual.
Preferably, the authentication unit 31 is provided with at least one user-defined viewing permission level. Preferably, the user can customize the level of the permission device for several types of information in the real names, customized names, three-dimensional profile characteristic information and basic data of the user and family members stored in the information storage unit 32. The arrangement has the advantage that the private information is prevented from being acquired and leaked by the unauthorized viewing terminal.
Preferably, the customized viewing permission level in the verification unit 31 is associated with at least one verification factor. Preferably, the verification factor can be customized by the user, and can also be a verification factor legally associated with the viewing permission level.
Preferably, the verification factor in the present invention is associated with the verification strength. The verification strength of the verification factor of the present invention is evaluated based on the extent and degree of influence of the individual's behavior. Namely, the verification strength of the verification factor of the invention can carry out authentication with different strengths on the privacy information of the user. For example, when viewing facial images or facial part depth information of a user and his family members, it is necessary that the viewing object has authentication factor authentication with high authentication strength, i.e., authentication is relatively strong. For example, when viewing only the three-dimensional contour information of the user and the family members thereof, it is necessary to view the subject with the authentication factor authentication having a lower authentication strength. For example, when viewing behavior trace information associated with time and location, it is necessary to view verification factor authentication with moderate verification strength for an object, which is customized by a user. That is, the level of detail that the user privacy information can be viewed is associated with the viewing permission level and the verification factor.
In the invention, no matter how strong the authentication and verification strength is, the verification factor must be unique and is uniquely associated with basic data such as real names, IP addresses, frequent places and the like in the privacy information.
The verification factor in the invention can be verified biological factor, gesture information or data information. The verification strength of a verification factor refers to the uniqueness guarantee and likelihood that the verification factor can be broken. The verification strength can be expressed as a specific value, and can also be a language description of the cracking difficulty level, such as a strong, medium, weak and the like, which represents the evaluation result of the difficulty level. The strength of verification may also be a numerical description of the difficulty rating, such as 1-5 indicating an increase in difficulty rating or a decrease in difficulty rating. The intensity parameter may also be a description of the color, shape, and combinations thereof of the difficulty rating for cracking, such as a gradual change from green to red indicating an increase in difficulty rating or a decrease in difficulty rating.
For example, a piece of code is used as a verification factor, and the length and complexity of the piece of code determine the possibility of collision which can occur in the piece of code and the possibility of being cracked. A binary code of six bits in length, up to 2 6 =64 states. If tens of thousands of people use the code with 6 digits, the collision rate is very high, and the cracking is very easy. If 256 bits code, 2 256 The collision rate can be greatly reduced when the same number of people use the single-state anti-collision system, the cracking difficulty is increased, and the strength of the verification strength is higher. If the fingerprint is taken as a verification factor and belongs to biological characteristics, the possibility of collision is extremely low, namely, the possibility of cracking is also very low. Therefore, the verification factor of the invention is associated with the verification strength of the verification factor, and the safety degree of important information types can be improved by improving the difficulty level of the verification factor, so that the possibility of information stealing and leakage is further reduced.
Preferably, the verification factors with different verification strengths in the present invention are not limited to a segment of code, and may be an asymmetric encrypted private key or public key, or all kinds of biometric factors capable of indicating unique features, such as facial information, facial expressions, fingerprints, voiceprints, iris features, gesture features, and the like. In the authentication, it may be determined according to the verification strength that the single authentication is performed according to a single factor or the joint authentication is performed according to multiple factors. Namely, the invention evaluates the verification strength of the verification factor, limits the security level of the checking behavior of the checking object, and prevents the privacy information of the user from being impersonated to be used under the condition of not revealing all the privacy information of the user, particularly prevents important privacy information from being revealed.
Preferably, the verification unit 31 of the cloud management platform 3 of the present invention is provided with a legal authority level corresponding to a viewing terminal of a national legal department and a verification factor thereof. Namely, the checking terminal which is legally authenticated can exceed the checking authority level set by the user and check the identity information with a higher level. For example, the viewing terminal of the relevant department can directly view the identity information of a higher level beyond the viewing permission level set by the user through authentication. The method has the advantages that when the relevant department legally checks the real information, the normal management behaviors of the society are prevented from being blocked due to the limitation of false information and permission levels, and malicious molecules can be prevented from hiding the information by setting the checking permission levels.
Preferably, the verification unit 31 of the cloud management platform 3 of the present invention only feeds back the viewing result based on the content viewing inquiry instruction sent by the verification terminal, and does not feed back the specific information of the user and the family members thereof. For example, when the property management terminal of the property of the cell inquires whether a certain house weighting is a person through a network, the verification unit 31 feeds back result information of "person present" or "no person" based on the viewing authority level of the property management terminal, without displaying specific person information in the house. Or, when the property management terminal inquires about the old people over 60 years old from the verification unit through the network, the verification unit 31 feeds back "yes, X people" or "no" based on the instruction of the inquiry content, thereby avoiding leakage of information such as specific age, birthday date and the like of the old people among family members, enabling the property management terminal to obtain necessary statistical information without grasping privacy information of the user, and providing related services. For example, during epidemic situation management, a community management terminal has a special authority level for collecting body temperature information. The community management terminal or the property management terminal sends a query instruction to the verification unit 31, and when the body temperature of any person exceeds 38 degrees, the verification unit 31 feeds back "none" or "address information + number of persons + body temperature abnormal time" after verifying and checking the authority level. According to the arrangement, the epidemic situation management and control can reduce the waste of human resources of community personnel home investigation, reduce close contact between people, directly acquire necessary data, and avoid the user from providing false information. Meanwhile, the information fed back by the verification unit 31 does not directly leak privacy information such as the real name of the individual. And when the community staff need to isolate the abnormal body temperature, the staff get on the door to take corresponding measures.
Preferably, when the judgment module in at least one cloud management platform determines that dangerous situations such as a fall, a slip and the like occur and gives an alarm according to the posture profile information of the human body acquired by the TOF sensor, the verification unit 31 of the cloud management platform 3 sends basic information of the fallen person, such as height, weight, age, fall time, fall place, emergency contact phone and the like, to the corresponding medical terminal together with the alarm information. Preferably, the authentication unit 31 feeds back information based on a dedicated instruction of an external authentication terminal. For example, a patient in a coma is alone at home, and it is difficult for a medical staff to provide necessary identity information by asking the patient in case of emergency needs. At this time, the medical staff associates with the verification unit 31 of the cloud management platform 3 in a wired or wireless manner through the viewing terminal having a dedicated instruction, so as to obtain basic information of the patient, even disease history and allergy history, and perform first aid on the patient to avoid an inappropriate medical measure from aggravating the illness. Therefore, the invention has the advantages that the requirement of rapidly acquiring necessary identity information in an emergency can be met, and the health and the safety of the user and family members thereof are ensured.
Preferably, in the case that the mobile terminal 1 establishes data connection with the cloud management platform 3, the verification unit 31 in the cloud management platform 3 synchronously displays the content fed back to the verification terminal by the mobile terminal 1, so that the user and the information viewer can simultaneously grasp the provided information content and the detailed degree of the provided information, thereby avoiding the viewer from acquiring redundant privacy information.
Preferably, the association of at least one verification factor, viewing permission level and information type, information detail degree of the mobile terminal 1 are set by user self. For example, in the case where the mobile terminal itself is provided with a use password, the user can associate the type of information and the degree of detail of the information by increasing the authentication factor, thereby increasing the privacy level of the private information.
Preferably, the control device 2 of the present invention determines body posture characteristics based on the three-dimensional profile information of the individual uploaded by the at least one TOF sensor, and controls the start of the controlled device 4 according to the association between the body posture characteristics and the user-defined device start sequence, thereby realizing an intelligent living environment in which the home controlled device is started according to the living law and living habits of the user. For example, when the child enters the room to sleep, the temperature of the air conditioner is automatically turned on to 26 degrees. When the sleeper in the room does not include a child, the temperature of the air conditioner is automatically turned on to 20 degrees.
Preferably, the cloud management platform 3 further comprises a data processing unit for processing data uploaded by the TOF sensor. The data processing unit can be one or more of an application specific integrated chip, a server and a server group.
Preferably, the verification unit 31 may be one or more of an asic, a server, and a server group. The information storage unit 32 may be one or more of an application specific integrated chip, a server, and a server group.
It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of this disclosure, may devise various solutions which are within the scope of this disclosure and are within the scope of the invention. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not intended to be limiting on the claims. The scope of the invention is defined by the claims and their equivalents.
