Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As described above, the smart device generally has a function of connecting to a network, and can perform operations such as querying, binding, and managing through an APP installed on a smart phone or a tablet computer. To manage and operate the intelligent device, a one-to-one operation relationship between the external terminal and the intelligent device needs to be established, that is, binding is performed. The management and operation of the intelligent device cannot be realized without binding. In the prior art, a user realizes binding by scanning a binding two-dimensional code attached to an intelligent device through an external terminal, however, the two-dimensional codes of the intelligent devices of various manufacturers are generated according to a certain rule and are easily obtained by analysis and derivation according to the rule, so that the safety problem of false binding occurs.
The security binding method, system and intelligent device provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a security binding method applied to an intelligent device, where the method includes the following steps:
step 101: receiving a binding instruction sent by an external terminal, wherein the binding instruction is generated by the external terminal by scanning a two-dimensional code attached to the intelligent equipment to obtain an equipment code of the intelligent equipment and generating the equipment code according to the equipment code;
step 102: after receiving the binding instruction, randomly selecting a target key from at least one key installed on the mobile terminal and triggering a timer to start countdown of a preset time value;
step 103: displaying information of the target key and countdown of the timer to prompt a user to press the target key before the countdown is finished;
step 104: and when a signal triggered by the pressing of the target key is received before the countdown of the timer is finished, sending permission information indicating permission for binding to the external terminal through a server according to the equipment information of the external terminal.
In the embodiment of the invention, when a user needs to bind, the two-dimensional code attached to the intelligent equipment is scanned through the external terminal to obtain the equipment code of the intelligent equipment, and the binding instruction is generated according to the equipment code. After the intelligent device receives the binding instruction, in order to ensure the binding safety and prevent the malicious binding of the remote end, a target key is randomly selected from the keys installed on the intelligent device, a timer is triggered to start countdown, after the countdown is started, the information of the target key and the remaining time of the countdown are displayed, and a user is prompted to press the target key before the countdown is finished. And the intelligent equipment monitors whether the target key is pressed or not during the countdown duration, and if a signal triggered by the pressed target key is received before the countdown is finished, the intelligent equipment feeds back the information to the external terminal through the server according to the equipment information of the external terminal to inform that the binding is allowed. According to the scheme provided by the invention, on the basis of the traditional two-dimensional code scanning binding, the step of pressing the entity key for verification is added, and as the short-distance operation is required and the target key of the intelligent equipment is required to be pressed within the time limit, the key can be pressed only at a place close to the intelligent equipment, and the malicious binding at the far end cannot control the entity key for verification, so that the intelligent equipment can be safely bound.
Specifically, the smart device is a device capable of performing data communication with the outside through the internet (the smart device is connected with the APP through the cloud, and the user can perform remote control on the smart device at home). With the increasingly widespread application of home appliances in the internet of things, the market proportion of NBIoT, 4G and large-screen intelligent home appliances is gradually increasing, and one feature of such home appliances is that they can be actively networked, such as automatically networked when being powered on or directly networked on a screen. After the products are networked, how to safely bind the intelligent household appliances with real users is an important part in the current product research and development.
In an embodiment of the present invention, the randomly selecting a target key from at least one key installed in the target key includes:
determining the number N of installed keys, wherein N is a positive integer;
creating a random array comprising N elements; each element in the array represents a target key;
determining a length variable according to the length of the array, wherein the length of the array is the number of the digits contained in the array;
determining an index value of the random array according to the length variable;
determining an element from the random array according to the index value;
selecting the target key characterized by the determined element.
Specifically, in order to further increase security, on the basis that the physical key needs to be pressed for verification during binding, the key that needs to be pressed for each binding may be set to be random, so as to further improve the security of binding. Specifically, determining a positive integer N of the number of keys installed on the intelligent device, and creating a random array comprising N elements; each element in the array represents a target key respectively, and a length variable is determined according to the length of the array, namely the number of the included numbers; and determining an index value of the random array according to the length variable, and randomly selecting an element from the random array according to the index value. Since each element corresponds to one key, the key to be pressed is the key corresponding to the element.
In an embodiment of the present invention, displaying the information of the target key and the countdown of the timer includes:
determining the key name of the target key, wherein the key name of each key is the name of a function triggered when the key is pressed;
generating prompt information for indicating a user to press a target key according to the key name;
calling a pre-created display plug-in;
and sending the countdown to the display plug-in unit according to a preset sending period through the timer so that the display plug-in unit displays the countdown.
In order to more intuitively remind the user of pressing the target key before the countdown is finished, the key needing to be pressed and the countdown remaining time can be displayed through a pre-created display plug-in. For example, when the countdown time is 30 seconds and the key to be pressed is the standby key, the display plug-in displays "please press the standby key within 30 seconds" on the external screen of the smart device, and the displayed countdown is updated in real time to further prompt the user to press the standby key within the countdown time. And if the user presses the standby key within 30 seconds, the intelligent device replies the permission information of the external terminal, and if the pressing is not completed within 30 seconds, the intelligent device fails to be bound with the external terminal.
In an embodiment of the present invention, after randomly selecting a target key from at least one key installed on the mobile terminal, the method further includes:
determining a key value of the target key;
stopping executing the action of reporting the key value to an application layer, wherein the application layer executes corresponding operation according to the key value when receiving the key value;
and when the countdown of the timer is finished or the target key is triggered, the action of reporting the key value to the application layer is recovered to be executed.
Specifically, after the target key to be pressed is determined, the next pressing of the target key should only be used for verification, and the original corresponding function is not executed any more, otherwise, when the target key is pressed, a conflict situation may occur, resulting in a binding failure. For example, when it is randomly determined that the target key to be pressed is the power on/off key, if the original function of the power on/off key is not shielded, the smart device executes the power off operation when the user presses the power on/off key, thereby causing a binding failure. Therefore, after the target key is determined, the key value of the target key is determined, and since the triggering of the function corresponding to the key is the function represented by the key value corresponding to each key, the corresponding operation is executed by reporting the key value of the target key to the application layer by stopping execution. After the countdown of the timer is finished or the user presses the target key once to finish the verification, the action of reporting the key value of the target key to the application layer is replied and executed to recover the use of the target key.
In an embodiment of the present invention, the method further includes: pre-collecting a plurality of voice samples corresponding to at least one key name to construct a training sample set; obtaining a voice template of the key name through iterative training based on the training sample set; setting a matching threshold value for the voice template according to the similarity between the voice samples acquired in the iterative training; wherein the obtaining of the voice template of the key name through iterative training based on the training sample set comprises: selecting a first voice sample from the training sample set as an initial intermediate template; sequentially selecting untrained second voice samples from the training sample set to execute the iterative training so as to update the intermediate template; and responding to the iterative training end condition, and storing the intermediate template as the voice template of the key name.
Specifically, after the target key is randomly determined and countdown is started, the display module of the intelligent device can remind a user of pressing the target key of the intelligent device through voice broadcasting besides displaying. In order to enable voice broadcasting to be more accurate, a plurality of voice samples corresponding to at least one key name are collected in advance to construct a training sample set, a voice template of each key name is obtained through iterative training of the training sample set, and a middle template is updated through continuous training. After the iterative training is finished, the intermediate template after the iterative training is carried out for multiple times is used as a voice template of the key name, and the keys required to be pressed by the user can be broadcasted through voice better and accurately through the voice template.
In an embodiment of the present invention, after determining the key name of the target key, before generating, according to the key name, a prompt message for instructing a user to press the target key, the method further includes:
recognizing the pronunciation of the key name, and determining a voice template with the matching degree higher than the highest matching degree in the matching threshold;
generating voice information corresponding to the key name according to the voice template;
and playing the voice information to prompt the user to press the target key.
In summary, in the embodiments of the present invention, through interaction between the external terminal and the smart device, the security of the binding of the smart device is ensured in a manner that the user presses the key of the smart device, and the specific implementation process is as follows:
1: the intelligent equipment supporting 4G is inserted into the SIM card, the intelligent equipment is started to be automatically networked, the intelligent equipment is communicated with the mqtt server through an mqtt protocol, equipment codes are registered and activated, and the communication unique identification of the intelligent equipment is consistent with the two-dimensional code of the intelligent equipment;
2: a user logs in a client APP through an external terminal, scans a two-dimensional code of the intelligent device to identify a device code, the APP is connected with an mqtt server to inquire whether the device is registered and activated, if the device finishes the step 1, the communication authority of the device is obtained, the step 3 is entered, and otherwise, the user is prompted to insert an SIM card to activate the device;
3: the client APP sends a user binding instruction to the intelligent equipment through the mqtt server, the intelligent equipment receives the user binding instruction, then the intelligent equipment prompts a user to press an intelligent equipment function key in a voice mode, the user presses the intelligent equipment function key within 30 seconds, then the intelligent equipment replies a client APP equipment binding permission instruction, the client APP receives the intelligent equipment binding permission instruction, then a user server interface is started, the binding relationship between the user and the intelligent equipment is added, and the user and the intelligent equipment are successfully and safely bound; the client APP is communicated with the mqtt server through an mqtt protocol and communicated with the user server through an https protocol.
4: and 3, sending an mqtt binding message to the intelligent equipment by the client APP, counting down for 30 seconds to monitor equipment feedback, carrying out voice prompt on the intelligent equipment, counting down for 30 seconds to monitor function key pressing, informing the client APP equipment of allowing binding by the intelligent equipment through the mqtt message by the intelligent equipment when the function key is pressed within 30 seconds, allowing binding by the client APP within 30 seconds, communicating with the user server through an https protocol, and adding the binding relationship between the user and the intelligent equipment.
5: and if the client APP binding countdown does not receive the intelligent equipment binding permission message within 30 seconds, the user binding the equipment fails. Within 30 seconds of intelligent device binding countdown, the intelligent device function key is not pressed, the intelligent device informs the client side APP device of refusing to bind through the mqtt message, the user binds the device failure, and the problem that the intelligent device is maliciously bound by code scanning by other people is solved.
