Detailed Description
As shown in fig. 1, in the embodiment of the present invention, an intelligent community security method based on the internet of things is characterized by including the following steps:
s1, configuring a special communication link protocol, wherein the communication link protocol is used for controlling communication between the community server and the mobile terminal.
Optionally, the step S1 includes:
s11, dividing the community camera into a public interval camera, a semi-public interval camera and a privacy interval camera;
the camera in the public interval is a camera related to a public area in a community range, the camera in the semi-public interval is a camera arranged in the public interval, the private interval and a transition zone in the community range, and the camera in the private interval is a camera arranged in the private interval and can be flexibly arranged according to the distribution of buildings and structures in the community range.
S12, configuring different authentication authority weights of the public interval camera, the semi-public interval camera and the privacy interval camera corresponding to the community server and the mobile terminal; and configuring a public interval camera, a semi-public interval camera and a privacy interval camera to correspond to the mobile terminals which are authorized to participate in the verification of the user and the threshold value of the number of the mobile terminals needing to be verified.
Through configuring the public interval camera, the semi-public interval camera, the privacy interval camera corresponds the community server, and mobile terminal's different authentication authority weights, make different cameras can go the authentication through different corresponding community servers, mobile terminal, the purpose of setting up the weight lies in more decentralization, transparentizing to the validity verification of acquireing the video demand, avoid because a property is a right too big, lead to the video to acquire the fuzzy contradiction deepening between the property owner and the property of demand validity authentication standard.
S13, configuring a special communication link protocol according to the authentication authority weight and the quantity threshold, wherein the communication link protocol is verified in a verification chain form.
By configuring a special communication link protocol, the interaction between the community server and the mobile terminal can be more safe and transparent. In an embodiment of the invention, the community server represents a property manager's server; the mobile terminal is a terminal device used by a proprietor.
Alternatively, the verification chain may be in the form of a block chain, and the community server and the mobile terminal are added to the block chain in advance.
S2, configuring a use number corresponding to the user in the mobile terminal, wherein the use number is used for identifying the user identity information;
since most of owners live in buildings as units, when some cameras related to the buildings are used for shooting videos, the owners and properties of the buildings may only need to agree, and therefore, by configuring the use numbers corresponding to the users in the mobile terminals, not only can the privacy of the users be protected, but also the users can freely select whether to agree or not, and the privacy is protected. And can also select a mobile terminal corresponding to the associated owner when a video acquisition demand occurs by using the number. For example, when the number of the building is 2, the verification of the mobile terminal and the community server of the owner corresponding to the building of the number 2 is only required to be passed. In addition, the requirement of cameras in a certain semi-public interval, such as a camera in a cross zone, and the agreement of owners of a building 2 and a building 3, only need to circle corresponding use numbers.
S3, when a video acquisition demand occurs, verifying the video acquisition demand according to a preset communication link protocol and a use number, and when the verification is passed, sending the corresponding video to the corresponding mobile terminal;
alternatively,
the step S3 includes:
s31, when a video acquisition demand occurs, judging a use number corresponding to the requested mobile terminal according to the demand; judging the corresponding type of the community camera corresponding to the required video;
s32, determining the authentication authority weight of the community server and the mobile terminal and the participation number of the corresponding mobile terminal according to the community camera type;
optionally, the authentication authority weight of the community server and the mobile terminal is determined by the type of the community camera, and a dynamic adjustment mode can be adopted. In a possible embodiment, the weight proportion of the community server is dynamically adjusted according to the number of the fed-back mobile terminals, so that the verification process can be prevented from being illegally cracked when the number of the participating mobile terminals is too small, and the reliability of the community server is relatively better than that of the mobile terminals.
In a more preferred embodiment, according to the result of checking the previous authentication process in step S4, the weight of the mobile terminal is further adjusted, and a higher weight is given to a mobile terminal with high credibility, and a lower weight is given to a mobile terminal with low credibility until the authentication qualification is cancelled.
S33, broadcasting a verification requirement to a verification chain according to the use number corresponding to the requested mobile terminal, wherein the verification chain comprises the mobile terminal authorized to participate and a community server;
s34, obtaining the verification result fed back by the mobile terminal with the right to participate and the community server, judging whether the authentication right weight and the quantity threshold meet the requirements or not according to the verification result, and jumping to the step S4 when the authentication right weight and the quantity threshold meet the requirements, otherwise, terminating the process.
In a more preferred embodiment, a feedback time node is preset, the number of the mobile terminals which are fed back when the time node arrives and are authorized to participate is judged, and when the number of the mobile terminals which are authorized to participate meets the requirement, the authentication authority weights of the community server and the mobile terminals which are authorized to participate are dynamically adjusted. One way to perform dynamic adjustment is to set the number level of the mobile terminals that are authorized to participate into the dynamic adjustment as the number of the mobile terminals that are authorized to participate into the dynamic adjustment meets the requirement, and divide the number level into a first level, a second level and a third level, where the first number level is greater than the second number level, and the second number level is greater than the third number level. Specifically, when the number level of the mobile terminals is a first level, the authentication authority weight of the community server is reduced; when the number level of the mobile terminals is a first level, keeping the authentication authority weight of the community server unchanged; and when the number level of the mobile terminals is a third level, increasing the authentication authority weight of the community server.
The implementation of the present embodiment has the advantages that: by setting the time node for feedback, the number of the mobile terminals which are fed back when the time node arrives and have the right to participate is judged, so that the overlong verification time can be avoided, and the timeliness of video acquisition is prevented from being reduced. And further according to the number of the fed-back mobile terminals which are authorized to participate, when the number of the mobile terminals which are authorized to participate meets the requirement, dynamically adjusting the authentication authority weights of the community server and the mobile terminals which are authorized to participate, so that when the number of the mobile terminals which meet the requirement (but the number is not too much), the security of the whole verification process is ensured by increasing the authentication authority weight of the community server, and the adjustment is dynamic, so that the community server cannot be always in the condition of higher authentication authority weight, and the overall security during continuous verification is ensured.
Optionally, the step S34 includes:
s341, obtaining verification feedback information returned by the mobile terminal authorized to participate and verification feedback information returned by the community server;
s342, judging whether abnormal terminals exist in the involved mobile terminals, extracting weight information from all verification feedback information when the abnormal terminals do not exist, and jumping to the step S343; otherwise, go to step S345.
Optionally, the determining whether there is an abnormal terminal in the participating mobile terminals in S342 includes:
acquiring historical verification information of all mobile terminals participating in verification, and converting all the historical verification information into a first verification matrix;
estimating according to historical verification information of each past time point to obtain different presumption values of each mobile terminal participating in verification at the current time point, calculating to obtain a presumption value mean value of each mobile terminal participating in verification at the current time point, and generating an estimation vector according to the presumption value mean value. The estimation of the historical authentication information at each time point to obtain different guess values of each mobile terminal participating in authentication at the current time point is due to the fact that certain errors may exist due to the estimation.
And judging whether abnormal terminals exist in the participating mobile terminals according to the estimation vector.
The principle of the embodiment of the invention is that although the verification chain can adopt a block chain form, the community server and the mobile terminal are added into the block chain in advance, the number of the mobile terminals participating in the community range is limited, and the risk of illegal cracking still exists in the verification process through the block chain. By judging whether abnormal terminals exist in the participating mobile terminals or not, the abnormal mobile terminals in the verification chain can be eliminated in time, and the safety of verification is improved.
Optionally, the first validation matrix is as follows:
estimating according to historical verification information of each past time point to obtain different presumption values of each mobile terminal participating in verification at the current time point as follows:
the average of the guess values of the current time point of the ith mobile terminal participating in the verification is represented as follows:
c′itc'1t,c′2t,...c′ntIt represents the average value of the guess values of each mobile terminal, and converts the average value of the guess values of all the mobile terminals into a vector expression form, and the estimation vector form is as follows:
Y＝(c′1t,c′2t,...c′nt)T。
through the processing of the embodiment of the invention, the error that the illegally invaded or controlled mobile terminal becomes an unreliable node due to the deviation of the verification is effectively reduced, so that the illegally invaded or controlled mobile terminal is easier to find, and the verification process is not easy to tamper by cooperating with other participatory mobile terminals.
Judging whether an abnormal terminal exists in the participating mobile terminals according to the estimation vector can be realized by the following modes:
calculating the minimum variance of the vector cluster formed by the estimation vectors, wherein the specific formula is as follows:
S343, judging whether the extracted weight information meets the requirement of the authentication authority weight, and jumping to the step S344 when the extracted weight information meets the requirement of the authentication authority weight; otherwise, go to step S345;
s344, judging whether the participating mobile terminals meet the requirement of a quantity threshold, and jumping to the step S4 when the participating mobile terminals meet the requirement; otherwise, go to step S345;
s345, this flow is terminated.
And S4, verifying the verification process, and sending the corresponding incentive data to the community server and the corresponding mobile terminal according to the verification result. It is understood that any mobile terminal may be a mobile terminal participating in authentication, and may also become a mobile terminal requesting video.
The beneficial technical effects are as follows: compared with the prior art, the intelligent community security method based on the Internet of things can realize the following steps: the method comprises the steps that a use number corresponding to a user is configured in the mobile terminal, and the use number is used for identifying user identity information, so that the personal privacy of the user who performs verification is guaranteed not to be disclosed; the video acquisition requirement is verified through the preset communication link protocol and the use number, so that the verification process is more reliable, and the verification process is more transparent and can not be changed due to the fact that the property is determined to be lost or not only in the actual video monitoring and calling process; and the verification process is verified, and the corresponding incentive data are sent to the community server and the corresponding mobile terminal according to the verification result, so that more owners can be encouraged to participate in verification, and the positivity of video calling verification is improved.
