Description
Technical Field
The invention belongs to the technical field of intelligent Internet of things communities, and particularly relates to a cloud platform-based intelligent community system.
Background
The wisdom community can lay the sensing thing networking in its space range and community's building, and this thing networking includes a large amount of sensing equipment, for example video acquisition equipment, humiture sensing equipment, air quality and particulate matter sensing equipment, smoke sensing equipment, infrared temperature measurement equipment etc.. The sensing equipment can upload sensing data based on an Internet of things communication protocol, so that the property management platform of the intelligent community can monitor the community space range and the security state, the air environment state, the fire state and the like in the community building based on the sensing data. The sensing devices may also collect and provide sensing data in response to instructions from the property management platform. The types and scales of communities in cities are various, and the communities have ultra-large communities with hundreds of buildings and hundreds of thousands of resident population, and also have small-scale communities with few resident population, which are formed by two or three buildings or a single building. Therefore, in order to manage communities, many community management systems exist in the prior art.
For example, patent document CN110415401A discloses a property intelligent management system based on smart community, which includes a vehicle management subsystem, a security management subsystem, a fire management subsystem, a management server, an intelligent display terminal and an information push management terminal; the management server is respectively connected with the vehicle management subsystem, the security management subsystem, the property management subsystem, the intelligent display terminal and the information pushing management terminal, and the intelligent display terminal is connected with the information pushing management terminal. According to the invention, through the vehicle management subsystem, the security management subsystem and the fire management subsystem, the safety of vehicles, security and fire in the community can be detected, and the vehicles, abnormal identity visitors and fire conditions in the corridor are processed according to the detected information, so that the property management efficiency is improved, the safety and order of the community are greatly improved, the community supervision efficiency is realized, and the property and personnel safety of the community is maintained.
However, in the smart community management system in the prior art, protection and view restriction classification of private data of a user are generally not performed, so that even though the private data is stored in an encrypted manner, a terminal with authority to view the private data can view a large amount of unnecessary private data. Moreover, in the future of the internet of things, along with the popularization of smart homes and smart home systems, the community management system must establish data connection with the smart home system of the user to obtain partial data, so that identity verification, community management and notification are performed. Under the condition that the obtained private information is not properly managed or the management level is weak by the viewing party to which the viewing terminal belongs, the private data of the user is easily leaked in a large amount and even utilized by illegal persons. For example, the management level of the community is different, and for the community with weak information management, the staff may leak the information privacy of the user through various ways. Therefore, there is a great potential safety hazard in opening all private data to the terminal with the viewing authority. How to enable the community to manage the community and avoid obtaining unnecessary private information is a technical problem which must be solved by the future intelligent community based on the internet of things.
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 intelligent community system realizes identification and payment of resident data through technical means such as face identification, face registration and face payment. Therefore, the face image becomes a part of privacy protection. However, in the prior art, no matter identity authentication, community image acquisition and identity information display are performed, the real name, the identity card number, the face image and the living address of an individual are always displayed at the same time, for example, identity card information is displayed, so that privacy information of a user is kept by multiple parties, and because the information of one party is improperly managed and copied and diffused, property of the individual is lost. Therefore, the facial image information collected by the future intelligent community system is not properly managed, and a large amount of leakage of user privacy can be formed. How to avoid privacy leakage is a technical problem which must be solved, otherwise the development of the intelligent community system is blocked.
Aiming at the defects of the prior art, the invention provides a cloud platform-based intelligent community system, which at least comprises: the system comprises a plurality of TOF image sensors, a community management platform, a cloud management platform and a user terminal, wherein the TOF image sensors, the community management platform and the user terminal are respectively in data connection with the cloud management platform, the TOF image sensors collect three-dimensional contour characteristic information without facial image information and send the three-dimensional contour characteristic information to the cloud management platform, the cloud management platform stores the three-dimensional contour characteristic information and identity information of a user in a correlation mode, the identity information is correlated with a custom viewing permission level and/or a custom name set by the user terminal, and the community management platform counts management information of residents in a mode that the three-dimensional contour characteristic information, the custom name and necessary information are combined and are not privacy information enough. Through the collection of the three-dimensional profile characteristic information and the setting of the user-defined name, the invention realizes the virtual-real combination of the personal identity information, so that the information checking terminal can only obtain the necessary information with permission, but can not simultaneously check all the information of the user. Especially, after the community is legally registered, the personal behaviors in the community are determined to be enough through the three-dimensional outline characteristics, so that the privacy diffusion of face collection is avoided.
The cloud management platform carries out checking authority level verification on the checking terminal based on a user-defined checking authority level, and feeds back an information category corresponding to the checking authority level or an inquiry result only containing necessary information based on the community management platform and the checking authority level and/or verification factors of the user terminal. Through the setting of the verification factor and the setting of the user-defined permission, the permission for information viewing is actively set and changed to be actively set by the user by the viewer, and the situation that the viewer obtains redundant and unnecessary information based on a viewing path is avoided. Among the resident information, the single information does not constitute the private information. When real name + action + time + place constitutes private information. For reasons of assault, when the viewing party can only obtain single necessary information, the privacy leakage of the user is avoided.
Preferably, the TOF image sensor collects the personal three-dimensional profile characteristic information and the body temperature characteristic, the cloud management platform adjusts the identity change of the user based on the personal body temperature change, and at least one display terminal displays the image information of the user in a mode of combining the three-dimensional profile characteristic information and the body temperature characteristic. According to the invention, the three-dimensional profile characteristic information and the body temperature information are simultaneously acquired through the TOF image sensor, so that the waste of manpower and material resources for manually acquiring the body temperature information is reduced. The TOF image sensor can record the body temperature and the change thereof within a certain time, so that the body temperature data is not temporary data, and the defect of escaping body temperature control by taking medicines is overcome. Particularly, the community is concerned about the temperature change of residents during the epidemic situation. The TOF sensor is arranged without a large number of volunteers for measuring temperature, and accurate data related to time can be obtained according to the travel in the community of residents, so that the epidemic situation management of the community is perfected.
Preferably, the cloud management platform at least comprises an authority verification unit, a data analysis processing unit and a database, the authority verification unit and the data analysis processing unit respectively transmit data with the database in a one-way ferrying mode, wherein the authority verification unit verifies the checking authority to at least one checking terminal sending a checking request based on a user-defined authority and/or a verification factor, and in response to a verification result of the authority verification unit, the data analysis processing unit feeds back a corresponding information category or a corresponding query result to the checking terminal based on request information of the checking terminal. The setting of the cloud management platform, particularly the setting of the verification factor, makes it possible to view the query result of the terminal or the terminal. Normally, the information that the check terminal needs to acquire is single, for example, the property needs to check whether the community is a resident of the local community, the community provides benefits for the old, and only the check is needed to check whether the old is 60 years old or not. Therefore, the data analysis processing unit feeds back the query result according to the information request of the viewing terminal, and the related information is not directly extracted for display, so that the possibility of privacy information leakage is further avoided. For example, for the condition whether the age of 60 is satisfied, the data analysis processing unit only feeds back the information of the birth year, or directly feeds back yes and no, and information inquiry is realized, so that the error of workers is reduced, and the leakage of private information is reduced.
Preferably, the data analysis processing unit determines three-dimensional profile feature information of at least one control object within a limited distance from a specified object based on a plurality of two pieces of three-dimensional profile feature information in a scene acquired by the TOF image sensor, and under the condition that the viewing terminal has a viewing authority, the data analysis processing unit queries corresponding identity information from a database based on the three-dimensional profile feature information of the control object and sends the identity information to the viewing terminal and/or a user terminal of the control object. The exclusion and search for close contacts with virus-diagnosed subjects, for example, during epidemic control, is a considerable difficulty. The prior art determines the identity of a person in close contact and finds the person even with a single face image. The method has the defects that the distance between people cannot be accurately determined and measured in the video, and a special program is needed for secondary processing, so that the method is unrealistic. The invention converts the face image information into the three-dimensional contour characteristic information for collection, and the three-dimensional contour characteristic information is acquired by light reflection, so that the position information of the human body is necessarily involved in the data information. Therefore, the invention acquires the distance difference information among a plurality of people while acquiring the three-dimensional contour feature information. Under the condition of need, the three-dimensional contour characteristic information of the close contact person within the close contact range of 1 meter with the diagnosed object is calculated and selected through the three-dimensional contour characteristic information, so that the data calculation amount is small and the realization is easy. The information is matched through the captured face image, and the accuracy is low. Through the matching of the three-dimensional profile characteristic information of one person and the database information, the three-dimensional data is richer, the behavior track and the identity information of the person can be acquired more easily, the difficulty of information investigation required by prevention and control is reduced, and the possibility of privacy information leakage is not increased.
Preferably, under the condition that the three-dimensional profile characteristic information cannot be associated with identity information in the database, the TOF image sensor acquires real images of individuals corresponding to the three-dimensional profile characteristic information based on an image acquisition instruction of the cloud service management platform and feeds the real images back to the cloud service management platform and/or the community management platform for storage. The real image collected by the TOF image sensor contains the real contour data of the five sense organs of the person, compared with the planar image data, the personal characteristics are richer, and the accuracy of matching the identity of the person according to the three-dimensional contour image data by the national legal department is higher.
In the prior art, for non-residential area residents, property management needs personal identity information of staff level and identity card information, which undoubtedly also easily causes the diffusion and the propagation of personal information caused by the strictness of information management. Preferably, the smart community system further comprises a property terminal, the property terminal queries the residential information request from the cloud management platform based on the identity displayed by the user terminal, the property terminal directly allows the user to enter based on the query result fed back by the cloud management platform, or the property terminal allows the user to enter under the condition that the user allows the property terminal to automatically register basic information through the user terminal, wherein the user terminal synchronously displays the registered basic information. I.e. the registered information property personnel are not visible, the user himself can see. Even if the property person can see, it also shows a custom name, whose real association information is stored in the database. When necessary, such as illegal activities, are involved, the data are called out from the database by the national legal department. Under normal conditions, the request information sent by the property terminal is 'yes' or 'no' and the query result obtained by the property terminal from the cloud management platform is 'yes' or 'no', so that the management difficulty and complexity of property workers are reduced, and the intelligentization of community management is facilitated. Moreover, the community property does not need to store the identity information of the resident users repeatedly, and the possibility that the personal information of the users is leaked is further reduced.
Preferably, the viewing terminal, the property terminal and the third-party viewing terminal which are in data connection with the community management platform are provided with positioning devices, and the authority verification unit in the cloud management platform rejects the information request under the condition that the real-time position information acquired by the positioning devices is inconsistent with the registration position ranges of the viewing terminal, the property terminal and the third-party viewing terminal of the community management platform. That is, when the identity information and the behavior track information of the user are checked, if the check terminal is illegally moved, the corresponding information cannot be acquired even if the check authority and the verification factor are in accordance. The method is important for protecting the privacy information of the user, and the possibility that redundant viewing terminals are transferred and stolen by people is avoided.
The three-dimensional contour characteristic information at least comprises a point set contour image and a line contour image formed by unreal colors, so that the condition that human eyes visually check personal images, particularly human face images, is avoided, and the leakage of personal privacy is avoided.
The TOF image sensor at least comprises a light emitting assembly, a photosensitive assembly and a light imaging assembly, wherein the light emitting assembly is used for emitting infrared light, the photosensitive assembly is used for sensing data recording of the reflected infrared light, and the light imaging assembly is used for calculating and imaging according to sensing data of the photosensitive assembly. The TOF image sensor is favorable for reducing data storage, and is high in data sensitivity and high in data acquisition speed.
As described above, the invention avoids direct leakage of personal privacy data by improving the data acquisition permission, the verification mode and the data acquisition mode of the intelligent community system, so that the privacy information is protected without influencing community management.

Detailed Description
The following detailed description is made with reference to the accompanying drawings.
Example 1
As shown in the figure, the invention provides a cloud platform-based intelligent community management platform, which at least comprises a plurality of TOF image sensors 1, a community management platform 2, a cloud management platform 3, a user terminal 4 and a property terminal 5. The TOF image sensor 1 has two access modes, wireless and wired.
The community management platform 2 and the TOF image sensors 1 are connected with the cloud management platform 3 through Ethernet communication. The user terminal 4 and the property terminal 5 are both connected to the cloud management platform 3 through ethernet communication.
The TOF (Time of Flight) image sensor 1 is used for collecting community data and uploading the community data to the cloud management platform 3. The TOF image sensor collects three-dimensional contour characteristic information and body temperature information of a human body through infrared pulses. ToF image sensors measure the time required for light to travel a distance in a medium. Typically, this is a measure of the time it takes for the pulsed emission light to reach the object and reflect back to the ToF image sensor. TOF image sensors in combination with information storage units are capable of recording data up to 45 fps. The TOF image sensor can easily form a three-dimensional contour image using point set imaging with low frequency refresh.
Preferably, the TOF image sensor includes at least a light emitting assembly 11, a light sensing assembly 12 and a spot imaging assembly 13. The light emitting component is used for emitting infrared light. The photosensitive assembly is used for receiving the light reflected from the object. The light spot imaging component is used for forming the depth information calculated based on the time difference into a three-dimensional contour image in a point set mode. Preferably, the three-dimensional contour image may be a contour image including a detail feature, or may be a contour image including only a contour feature without a detail feature.
The light imaging component forms the light data recorded with the depth into three-dimensional contour characteristic information in the form of a point set. Preferably, the light imaging component displays the contour image information in a pseudo color or a single color. Preferably, the light imaging component sets the display profile image information based on changes in body temperature. The invention does not display the contour information with obvious light and shadow color difference, so that a viewer can only see a plurality of points with different densities and the contour of five sense organs in the same color, as shown in figure 2. The checking personnel can not directly identify the personal identity by checking the specific information of the face and the body characteristics of the person, namely, the personalized privacy information of the face characteristics, tattoos, hair colors, eyeball colors and the like of the person is protected, and the method is beneficial to the visualization of scenes and the protection of personal privacy information when necessary. The invention adopts the TOF image sensor to collect the personal information and has the advantages that firstly, the working distance is long, and effective and real-time depth information within 5m can be obtained; secondly, the application scene is wide, no matter whether the shot object has characteristic points or not, no matter whether the ambient light is strong (such as sunlight) or weak, effective depth of field information can be obtained; thirdly, the accuracy of the longer distance is high, and the relative accuracy of the TOF between the sensor and the shot object can reach the level of centimeter.
At least one image acquisition device, such as a camera or a still camera, may also be provided in the TOF sensor of the invention. At the moment when the face contour in the three-dimensional contour feature information of the optical imaging assembly is complete, the image acquisition device shoots at least one face image of the acquisition object based on the shooting instruction sent by the optical imaging assembly. And, the image capture device unidirectionally transmits the face image information to the cloud management platform 3 in an encrypted manner. In the case where it is necessary to view an image of an individual, an official law enforcement department views image information of the individual by inputting a designated authentication factor. For example, an official law enforcement department searches for a suspect, and the viewing authority for viewing the personal image is obtained by inputting a verification factor viewed by the official. The arrangement has the advantages that the mechanism with insufficient management capability can be prevented from viewing unnecessary personal privacy information, such as face image information, and can also be used for viewing the face image information of a certain person with enough authority, so that the condition that an official cannot trace a suspect or a criminal because the personal information is not stored is avoided.
For example, the TOF image sensor 1 may include an entrance guard device having a three-dimensional profile feature information acquisition function provided at an exit of the community. The three-dimensional profile data and the body characteristic data of the user can be collected through the access control device. Or, the TOF image sensor 1 may also be a plurality of video collecting devices with TOF image sensors, which are disposed in the community, and the image data of the people moving in the community can be collected by the TOF image sensor. Preferably, the TOF image sensor 1 is connected to several display terminals. Preferably, the TOF image sensor 1 combines the acquired three-dimensional contour feature information of the person or pet with the scene and transmits the combined information to the display terminal.
The plurality of display terminals display the personal characteristics in the monitoring scene of the community in a video mode of displaying the three-dimensional outline characteristic information of the person, so that the leakage of personal privacy in the community monitoring video is avoided. Preferably, the three-dimensional contour feature information of the present invention may be static or dynamic three-dimensional contour feature information displayed by a point set, or may be static or dynamic three-dimensional contour feature information filled with color, as shown in fig. 3. Namely, the staff of the display terminal can view the dynamic state of the people in each scene by viewing the three-dimensional contour characteristic information, but cannot directly see the specific face image and the body characteristics of each person. According to the invention, the arrangement of the TOF image sensor enables the community to normally acquire scene information in the community for management, and meanwhile, personal privacy information is not leaked.
Preferably, the cloud management platform 3 of the present invention includes at least a right verification unit 31, a data analysis processing unit 32, and a database 33. The authority verification unit 31, the data analysis processing unit 32 and the database 33 are connected with each other in a data unidirectional transmission mode, and therefore the data unidirectional transmission and the security in the transmission process are facilitated. Preferably, the right verifying unit 31, the data analysis processing unit 32 and the database 33 are connected to each other in a one-way ferry manner. The authority verification unit 31 includes one or more of an application specific integrated chip, a server or a server group. The data analysis processing unit 32 includes one or more of an application specific integrated chip, a server or a server group. The database 33 is used for storing community data, and may be one or more of a group of dedicated servers. The data analysis processing unit 32 includes one or more of an application specific integrated chip, a server or a server group.
The permission verification unit 31 is configured to perform permission level verification on the viewing terminal, and feed back an inquiry result that does not contain unnecessary information according to the permission level of the viewing terminal and the inquiry request information. The data analysis processing unit 32 is configured to perform data processing, analysis and control instruction transmission on the data acquired by the TOF.
The database 33 is used to store community data. The community data includes at least community resident data and community asset data. The community resident data refers to the identity data, detailed residence data, image data, and the like of resident users who live in a specified community. The identity data at least comprises information such as a real name, a self-defined name, gender, an identification number, a telephone number, a plurality of verification factors and the like. The verification factor is a unique verification factor. The identity data may even include academic information, medical information, learning information, insurance information, vehicle registration information, vehicle access information, and other information authorized by the user. Preferably, the identity information further includes temporary data temporarily input by the user in the living behavior, such as time of arrival at a specified place, identity verification at a certain viewing terminal, and the like.
In the prior art, the identity information of the users is always bound and displayed together. For example, the identity information display combination includes at least: real name + phone number, real name + identification number + phone number, real name + address information + phone information, and the like. Regardless of whether community personnel need telephone number information during checking, the telephone number information is always displayed together with real name and address information. In the case that community personnel manage information materials improperly, user privacy information is leaked and diffused.
The invention avoids the leakage of the user privacy information by setting the hierarchical viewing authority for the user identity information. Preferably, the database 3 is stored in an unbound association of identity data. That is, the database 33 feeds back single real information based on the instruction of the authority verification unit 31, instead of sending and displaying the information that is not requested together with the requested information without a corresponding information request, so that the viewing terminal intelligently views the requested necessary information or query result without obtaining unnecessary information, and the risk that the privacy information of the community users is all obtained and leaked by the viewing party viewing the authority is avoided.
The custom name of the present invention is a false name that has a unique statutory association with the user's real name. The custom name can be displayed in numerical code, text, and/or text symbols. The number of the custom names is not limited to one, and may be several. Alternatively, in the case where the user does not register a custom name in the national identification information registration division, the database 33 generates a custom name by himself/herself when the user identification information is input. The advantage of such an arrangement is that, under the condition that the real name viewing authority is not available, when any viewing terminal in the community system views the user information, only the user-defined name of the user can be viewed, so that the viewed information cannot be combined to form the privacy information of the user.
The plurality of user terminals 4 are connected with the cloud management platform 3 in a wired or wireless mode, so that the user can check own identity information and community public information. The community user can associate the identity information with the checking authority level and the verification factor through the user side 4, so that the privacy information which can be obtained by the checking terminal is limited, and the leakage of personal privacy by a checking party with insufficient information management level is avoided.
Preferably, several verification factors in the present invention are respectively associated with the intensity parameters. The intensity parameters of the verification factors of the invention are evaluated according to the influence range and degree of the behavior of the agent. That is, the strength parameter of the verification factor of the present invention can perform authentication of different strengths on the identity information of the user. For example, when viewing general identity information such as age, sex, telephone, etc., only general authentication of the viewing terminal is required. When important identity information such as a real name, an identity card number, image information and the like needs to be checked, a user needs to input a verification factor through the user side 4 to obtain a checking authority, so that the important identity information is obtained. However, no matter how high the authentication strength parameter is, the verification factor must be unique and uniquely associated with the data such as the real name, the identification number, the house location, the image information, and the permanent place in the privacy information.
The validation factors of the present invention have different intensity parameters. Preferably, the verification factor is not limited to a piece of code, and may be an asymmetric encrypted private key or public key, or all kinds of biometric factors that can indicate unique features, such as facial images, fingerprints, voiceprints, iris features, and features. When the authentication is carried out, the single authentication according to a single element or the combined authentication according to multiple elements can be determined according to the strength parameter of the authentication. Namely, the invention evaluates the strength parameter of the verification factor, limits the security level of the user behavior, avoids the privacy information of the user from being impersonated to use under the condition of not revealing all privacy information of the user, particularly avoids important privacy information from being revealed, and maintains the security and stability of the society.
The strength parameter of the verification factor of the invention represents the difficulty of being forged and cracked. The strength parameter may be a specific value, or may be a language description of the difficulty level, such as a strong, medium, weak, etc. evaluation result indicating the difficulty level. The strength parameter may also be a numerical description of the difficulty rating of cracking, for example, 1-5 indicates 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, when the verification factor is a string of Arabic numerals, the length and complexity of the numerals determine the likelihood of the verification factor being cracked or having multiple frequency collisions. A number of six bits of data of length, up to 2664 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. When the verification factor is a 64-bit computer code, it is 264The collision rate can be greatly reduced when the same number of people use the single-state, the cracking difficulty is increased, and the strength parameter 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. Thus, the verification factor of the present invention and its ownThe strength parameters are correlated, the safety degree of important information types can be improved by improving the difficulty level of the verification factor, and the possibility that the information is illegally stolen and leaked is further reduced.
The community management platform 2 of the present invention may be configured in a community property management center for use by community management personnel. Preferably, the community management platform 2 is used for managing community asset data and community user data. The community management platform comprises a plurality of community viewing terminals. The community management platform 2 may be a computer server. Under the condition that the three-dimensional profile characteristic information of the individual is not matched with relevant data, the cloud management platform 3 sends an image acquisition instruction to at least one TOF image sensor near the geographic position of the specified object. The TOF image sensor responds to an image acquisition instruction to acquire image information or video information of a specified object and feeds the image information or video information back to the database 3 of the cloud equipment management platform 3 for storage. The database 3 stores three-dimensional contour feature information of a designated object, image information or video information, and an automatically generated custom name in a manner of being associated with each other. For example, when a TOF image sensor configured in the community acquires a person who is not outside the community, that is, the three-dimensional contour feature information of the designated object does not match the custom name, the data analysis processing unit 32 of the cloud management platform 3 sends the three-dimensional contour feature information and an image acquisition instruction to at least one TOF sensor. And the TOF image sensor determines a specified object according to the three-dimensional contour characteristic information and acquires image information or video information. The invention has the advantage that community personnel can quickly know the flowing situation of non-registered population and the behavior track of the personnel in the community to carry out necessary management. If necessary, the data analysis processing unit 32 makes a query request to the database based on the three-dimensional contour feature information of the uncertain object, thereby obtaining the legal self-defined name of a stranger in the community and updating the original self-defined name recorded in the database 3 to the legal self-defined name, and even if the authority is sufficient, obtaining the real name and storing the real name. Moreover, through the setting of the user-defined name, community personnel only master the emigration information, the emigration information and the privacy information of the real name and the migration address of a certain user, and the privacy of the user is better protected. If necessary, the community system can request the user's real name from the user's native community or the public security data system by a custom name. The invention has the advantages that a large amount of archive data transfer between communities is not needed, the management of population migration information can be realized through automatic data interaction of the cloud management platform, the manpower and time for phone check and home check of a large amount of community personnel are saved, and real intelligent management is realized.
Preferably, the display unit of the user terminal 4 is capable of displaying an identification associated with the user identity. The identity mark comprises a user-defined name, a photo or an anti-counterfeiting mark. Such as two-dimensional code identification with photo information, custom name. When the user needs to be subjected to identity verification, the user realizes the identity verification through the identity identification of the user side and the verification of the checking terminal. The advantage of such an arrangement is that the registration of identity information can be performed quickly for the inflowing population, and accurate identity information can be obtained directly. Compared with the process of inquiring identity information from a database by using three-dimensional profile characteristic information automatically acquired by a TOF image sensor, the method saves time and data transmission amount, avoids data matching errors and is more convenient for information management of users.
Preferably, the manner in which the user associates the identity information with the viewing permission level and the verification factor includes the following manner.
And under the condition that the information type and the verification and verification authority level are in self-defined association, feeding back or displaying the corresponding identity information when the viewing authority level of the viewing terminal is not lower than the corresponding self-defined authority level.
And under the condition that the real name is associated with the verification authority level in a self-defining way, the real name is fed back when the viewing authority level of the viewing terminal is not lower than the corresponding self-defined authority level.
And under the condition that the information detail degree is in self-defined association with the verification permission level, the identity information with the corresponding information detail degree is fed back when the viewing permission level of the viewing terminal is not lower than the corresponding self-defined permission level.
In the case of associating the information category or the information detail degree with the verification authority level and the verification factor customization, the authority verification unit 31 feeds back at least one type of identity information associated with the verification strength parameter based on the strength parameter and the type of at least one verification factor input by the user side and/or the viewing terminal.
Preferably, the display content of the display unit of the user terminal of the present invention may be designated by the authenticated viewing terminal. Preferably, the display content can be displayed to both the authorized administrator and the user himself. The advantage of such an arrangement is that it is advantageous to display only the kind of information that needs to be verified, and not display unnecessary other identity information, thereby avoiding leakage of an unnecessary part of the identity information during viewing due to display.
Preferably, the state legal department has the highest authority verification factor and viewing authority level, and can view the identity information of the user beyond the user-defined authority of the user. For example, the viewing terminal of the national public security organization can obtain the highest viewing authority by inputting the specified verification factor, and can view all data in the database.
Preferably, the right verification unit 31 synchronously displays the query result or the identity information fed back to the viewing terminal that sends the information request on the display unit of the user side, so that the user can know the information and the detailed degree of the information viewed by the viewing party. For example, when the community checking terminal or the property checking terminal requests the cloud management platform 3 whether the user age is over 60, the authority verification unit 31 feeds back "real name + over 60" or "real name + under 60" based on the user age information in the database, so that the specific age and identity card number of the user are not disclosed, and a statistical worker is not required to calculate the age according to the birth year and month, thereby achieving the dual technical effects of not leaking the privacy of the user and reducing the error in statistics.
Preferably, when a shop in the community gives purchase preference to a user meeting a specified condition through the third-party viewing terminal, the viewing authority and the information request information are sent to the cloud management platform 3 by scanning the identity of the user terminal 4. The authority verification unit 31 of the cloud management platform 3 feeds back the query result based on the checking authority level of the third-party checking terminal, and displays the user-defined name + the birthday date, so that the user can obtain the birthday preference, and the risk of leakage of the identity card number information of the user can be avoided.
Preferably, a plurality of community management terminals and property terminals connected with the community management platform in the community are provided with positioning devices and registration positioning ranges. In the case where the positioning information of the positioning device is in the registration positioning range, the authorization verification unit 31 feeds back the query result or the corresponding information to the viewing terminal of the third party. In the case that the location information of the location device is not in the registration location range, the authorization verification unit 31 rejects the information request of the viewing terminal of the third party, thereby protecting the user information of the community. Preferably, the identity of the user terminal 4 is changed based on the body temperature information collected by the TOF sensor and the community-specified conditions. The identity change includes at least a color change, a set shape change, and the like. In the prior art, in an epidemic situation prevention and control interval, because the range of motion of a user cannot be associated with body temperature in a data acquisition manner, each unit, cell and store in a community can be allowed to enter only by measuring the body temperature through a specially-assigned person while identifying the identity of the user. So set up unable machine of realizing and verify, both extravagant manpower, also can only obtain interim body temperature data, consequently appeared the phenomenon that the user avoids the body temperature inspection through taking the cooling medicine, not convenient to the epidemic situation prevention and control. The TOF sensors can simultaneously acquire three-dimensional contour characteristic information and body temperature information of a user when the user enters an acquisition range of the TOF sensors. Therefore, the database 3 stores the body temperature information of the user at a plurality of times and places, so that the body temperature information of the user is related to changes. Namely, the body temperature information of the present invention is several data associated with time and place. Moreover, based on a plurality of three-dimensional profile characteristic information acquired by the TOF image sensor and image information in the same lens, the data analysis management unit can determine the distance range between people and store the distance range in a database of the cloud management platform.
When the body temperature information exceeds the threshold set by the community, the identity of the user terminal 4 changes correspondingly, such as color change, pattern change or shape change. The third-party terminal can send an information request to the cloud management platform by acquiring the identity of the user terminal, and obtains a query result of whether the body temperature of the user exceeds a threshold value within a specified time. And allowing the user to enter a specified place under the condition that the query result is met. Preferably, during epidemic situation prevention and control, after the specified user confirms diagnosis, the data analysis management unit can determine at least one control object intersected with the specified user within a set distance range by tracing the distance information between the three-dimensional profiles stored in the database, and send related information and identity change information corresponding to the indication to the user terminal 4. For example, a user carries an identity of a user terminal and displays the identity to a viewing terminal, the viewing terminal opens a gate when a query result is satisfied after obtaining the query result from a cloud management platform account recorded by the identity, and the user enters a designated place. According to the invention, through the arrangement of the TOF image sensor, the control of the body temperature, the crowd contact and the intersection of the user by the machine terminal can be realized under the condition that the privacy information of the user image, especially the face image and the like is not fully acquired, so that the effective assistance on epidemic prevention and control is realized, the spread of the epidemic is avoided, the verification work of workers collecting the body temperature of the user is reduced, and the infection risk of contact between people is further reduced.
For example, after the user a confirms diagnosis of a new coronavirus, the data analysis processing unit can determine three-dimensional contour feature information of a plurality of control objects which intersect with a within 1 meter within a specified time through the distance between the three-dimensional contours, and determine a custom name or face specific information of the control objects through the three-dimensional contour feature information. Under the condition that the face payment is popularized, the three-dimensional outline data of the face can be brought into the national household registration system. And further acquiring the necessary identity information of the control object through the database to perform activity control of the epidemic situation under the permission of the authority. Compared with the simple video monitoring in the existing public place, the method only displays images and cannot track the person track. According to the method, even if the community users are not recorded in the community, the behavior track and the contact crowd of the control object in the community can be determined based on the three-dimensional contour characteristic information acquired by the TOF image sensors and the position information and the time information of the TOF image sensors, and the infectious disease flow regulation work of an epidemic situation monitoring department is facilitated.
